ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR materially expands MCP authorization and target scope: tools can read or modify threads and scheduled work across projects, and external client callers receive bounded runtime permissions. Because it changes security-sensitive authentication/authorization behavior and introduces broad production capabilities, human review is warranted. You can add or adjust custom eligibility rules.

MCP tools now accept optional threadId/projectId targets that fall back to the calling thread, and resolve them anywhere in the environment instead of only the caller's project. The credential still sets the limits: a thread caller is capped by its own runtime and interaction modes and needs a live run to mutate. A caller without a thread (prepared for MCP OAuth clients) must name its targets, is capped by a runtime-mode ceiling, and gets thread_credential_required from tools that act as the calling thread.

… modes update_scheduled_task and delete_scheduled_task now refuse a task whose runtime or interaction mode is broader than the caller's limits, so a capped agent cannot rewrite a full-access task's prompt and have it run. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An in-thread agent that omits projectId searches its own project, like the other project tools; only a caller outside a thread searches all. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Renaming a thread, updating its metadata, and linking, unlinking or watching its pull requests now refuse a target thread that runs with broader modes than the caller, the same rule t3_thread_send and the queue tools apply. A thread changing itself is unaffected. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
- t3_thread_interrupt now refuses a target thread that runs with broader modes than the caller, like t3_thread_send. - t3_thread_update and the pull-request tools need the calling thread's live run before they change another thread, like every other cross-thread write. - schedule_task checks a caller-named project exists before recording a task against it.

… run A provider-session credential can outlive an unclean session stop.

pingdotgg#15219 authorizes an MCP edit against the task's modes before writing it. With the atomic partial update, a mode raise committed in between kept the higher mode while applying the restricted caller's patch, where main's full-row upsert wrote the checked modes back. The update now takes expectedRuntimeMode/expectedInteractionMode preconditions, checked inside the write transaction, and the MCP tool passes the modes it authorized.

Upstream pingdotgg#15892 makes scheduled runs queue instead of steering, the fork's 68b5524 change, so the fork line, its test and README bullet are dropped. PreviewAutomationBroker keeps the fork's host-reset reconnect message on pingdotgg#15219's new scope shape. Silent breaks fixed: the settle cascade moves to KeyedLock (pingdotgg#15577 deleted KeyedSerialExecutor), and the session tools read the new McpInvocationScope thread, refusing a client outside one.

…ants (#1636) ## Problem An external agent (another machine, another harness) had no safe way to coordinate T3 threads. The only options were the provider-session `/mcp` token or a broad admin credential. ## Change The owner approves a DPoP device grant with an MCP policy instead of scopes. The client then uses `/api/mcp/external`, a second MCP server with its own `t3_external_*` tools. | Aspect | Rule | | --- | --- | | Credential | DPoP device session, scopes `[]` | | Policy | `auth_external_mcp_grants`, keyed by session | | Reads | projects, threads, timelines, waits | | Mutations | create, send/steer, interrupt with `--mcp-coordinate` | | Boundary | granted projects only | | Ceilings | default `approval-required` and `plan` | | Retries | `auth_external_mcp_requests` binds key to request and result | | Lost result | retry recovers the committed message and its run | | Interrupt retry | pins its run, or no run, before dispatch | | Steering | a capped grant joins only the provider attempt it vetted | | Dispatch | refuses a capped send or create prompt once its attempt or the thread modes changed | | Later owner changes | apply to turns that start afterwards, as for any queued message | | Reused key, new payload | `invalid_request` | | Failures | MCP `isError: true`, text led by the code | | Provenance | `createdBy: agent`, `creationSource: mcp` | | Revocation | `t3 auth session revoke` ends it at once | | Isolation | own `Layer.fresh`; `/mcp` is unchanged | ```bash t3 auth device approve <code> --mcp-project <id> --mcp-coordinate ``` The token endpoint also omits `scope` for a scopeless grant. It used to fail with `500` after it had issued the session. ## Head | Commit | Content | | --- | --- | | `77023d822ba173f4be58619469f2ae16179f0750` | head; one docs-only commit | | `657bd5cf7f29aa63a04b13c6421baeac2618afba` | last code commit; the recordings and VM transcript ran here | `git diff 657bd5c 77023d8`: `docs/fork/internals/fork-delta.md` only, +2 −1. The recordings stand for the head; a reviewer confirms that equivalence. ```diff -| Credential | DPoP device session only; scopes `[]`, so no RPC or route accepts it | +| Credential | DPoP device session only; scopes `[]`, so scope-checked routes and RPCs refuse it | +| WebSocket | `/api/auth/websocket-ticket` needs only authentication; each socket RPC refuses it | ``` ## Recordings Recorded on an isolated QA VM against `657bd5c`.

One upstream doc, `orchestrator-mcp-server.md`, is corrected to the shipped provider credential lifetime. Probe from the guest with the read-only external credential: ```diff + /api/mcp/external → 200 - provider /mcp, DPoP or Bearer → 401 invalid_mcp_credential - /api/auth/clients, pairing-links → 403 insufficient_scope - /api/auth/pairing-token → 403 insufficient_scope ! /api/auth/websocket-ticket → 200 ``` The ticket route only requires authentication upstream; this PR leaves it unchanged. Every RPC on that socket requires a scope ([`RpcAuthorization.ts`](https://github.com/RSI-Software/t3code-hyprws/blob/77023d822ba173f4be58619469f2ae16179f0750/apps/server/src/auth/RpcAuthorization.ts)).

Payloads were valid but aimed at ids that do not exist, so even an accepted call could touch nothing.

The branch server ran with its own `.t3` and listened on the libvirt bridge only. The guest client was standalone Python with its own P-256 key, and had no T3, host, or provider credentials. ```diff + A, B, C: three grants, three keys, one guest + whoami: each client's own session and policy + one mcp-session-id, two credentials: each call answers as its sender + create K, retry K as sent → same thread + create with prompt → real Codex turn; retry → same run + steer → joins the vetted provider attempt + interrupt → interrupted + steer retry after the run ended → recorded result + owner clears every recorded result while run 3 is live: + interrupt retry → run 2, interrupted; run 3 untouched + steer and send retries → run 2, original delivery + create retry → run 1 - create K or send s1 retried with a changed payload → invalid_request - full-access create → runtime_mode_escalation_denied - reader create → capability_denied - no proof, Bearer, forged, another key's proof → 401 DPoP - replayed proof → 401 DPoP; browser origin → 403 - C after its 1m lifetime → 401 - A revoked → 401; B unaffected ``` Real-orchestrator regression: `ExternalMcpService.orchestrator.fork.test.ts` (owner elevates a thread under a used key; lost result for create, send, interrupt, idle interrupt; owner mode change during a running or starting turn; a send joins only its vetted attempt, also across an owner restart; dispatch refuses a send vetted under older modes; an owner raise that wins the lock mid-create keeps the prompt from starting). Auth: `ExternalMcpServer.auth.fork.test.ts` (real session store and DPoP verifier). Schema: `ForkSchema.fork.test.ts` adds the interrupt pin to an existing request table.

Upstream: several routes per environment (pingdotgg#15467/pingdotgg#15468), T3 MCP tools take explicit thread/project targets (pingdotgg#15219), reject accidental server launches (pingdotgg#15795), renderer history, preview console object release, file-link repair reverted (pingdotgg#15824), and assorted mobile/PR/server fixes. Fork reconciliation: - computer_send and the Codex monitor toolkit read the caller from the new McpInvocationScope.thread (client callers are refused). - `t3 <dir>` skips the desktop launch when a live server is recorded, so upstream's running-server refusal still applies. - Desktop quit also flushes renderer history after stopping Computer History. - Fork's inline visualizations render the raw message text now that the file-link repair is gone. - isApplicationActiveWakeup stays exported for the fork's probe-reset path.

…ants (#1636) ## Problem An external agent (another machine, another harness) had no safe way to coordinate T3 threads. The only options were the provider-session `/mcp` token or a broad admin credential. ## Change The owner approves a DPoP device grant with an MCP policy instead of scopes. The client then uses `/api/mcp/external`, a second MCP server with its own `t3_external_*` tools. | Aspect | Rule | | --- | --- | | Credential | DPoP device session, scopes `[]` | | Policy | `auth_external_mcp_grants`, keyed by session | | Reads | projects, threads, timelines, waits | | Mutations | create, send/steer, interrupt with `--mcp-coordinate` | | Boundary | granted projects only | | Ceilings | default `approval-required` and `plan` | | Retries | `auth_external_mcp_requests` binds key to request and result | | Lost result | retry recovers the committed message and its run | | Interrupt retry | pins its run, or no run, before dispatch | | Steering | a capped grant joins only the provider attempt it vetted | | Dispatch | refuses a capped send or create prompt once its attempt or the thread modes changed | | Later owner changes | apply to turns that start afterwards, as for any queued message | | Reused key, new payload | `invalid_request` | | Failures | MCP `isError: true`, text led by the code | | Provenance | `createdBy: agent`, `creationSource: mcp` | | Revocation | `t3 auth session revoke` ends it at once | | Isolation | own `Layer.fresh`; `/mcp` is unchanged | ```bash t3 auth device approve <code> --mcp-project <id> --mcp-coordinate ``` The token endpoint also omits `scope` for a scopeless grant. It used to fail with `500` after it had issued the session. ## Head | Commit | Content | | --- | --- | | `77023d822ba173f4be58619469f2ae16179f0750` | head; one docs-only commit | | `657bd5cf7f29aa63a04b13c6421baeac2618afba` | last code commit; the recordings and VM transcript ran here | `git diff 657bd5c 77023d8`: `docs/fork/internals/fork-delta.md` only, +2 −1.

One upstream doc, `orchestrator-mcp-server.md`, is corrected to the shipped provider credential lifetime. Probe from the guest with the read-only external credential: ```diff + /api/mcp/external → 200 - provider /mcp, DPoP or Bearer → 401 invalid_mcp_credential - /api/auth/clients, pairing-links → 403 insufficient_scope - /api/auth/pairing-token → 403 insufficient_scope ! /api/auth/websocket-ticket → 200 ``` The ticket route only requires authentication upstream; this PR leaves it unchanged. Every RPC on that socket requires a scope ([`RpcAuthorization.ts`](https://github.com/RSI-Software/t3code-hyprws/blob/77023d822ba173f4be58619469f2ae16179f0750/apps/server/src/auth/RpcAuthorization.ts)).

Payloads were valid but aimed at ids that do not exist, so even an accepted call could touch nothing. Opening the socket records only the session's own connection, as for any client. <details> <summary>Probe method</summary> | Item | Value | | --- | --- | | Server | `657bd5c` source, own `.t3`, `192.168.122.1:38917` | | Client | host Node script, own P-256 key; DPoP with `ath` | | Grant | `--mcp-project` one project, no `--mcp-coordinate` | | Output | reply tag, exit tag, scope, error tag; never the token or ticket | Effect RPC decodes a payload before the scope check, so an invalid payload fails decoding first. The probe sends valid payloads so the scope check is what answers. </details> ## Verification ```text npx tsc --noEmit -p apps/server → exit 0 vp test run <ForkSchema, mcp/external, ThreadManagementService, SelectionRestart> → exit 0 (43 tests) vp lint <changed .ts> → exit 0 vp run fork:ci → exit 0 vp run build (apps/server) → exit 0 ``` Transcript proof, round 4, on an isolated VM. The branch server ran with its own `.t3` and listened on the libvirt bridge only. The guest client was standalone Python with its own P-256 key, and had no T3, host, or provider credentials. ```diff + A, B, C: three grants, three keys, one guest + whoami: each client's own session and policy + one mcp-session-id, two credentials: each call answers as its sender + create K, retry K as sent → same thread + create with prompt → real Codex turn; retry → same run + steer → joins the vetted provider attempt + interrupt → interrupted + steer retry after the run ended → recorded result + owner clears every recorded result while run 3 is live: + interrupt retry → run 2, interrupted; run 3 untouched + steer and send retries → run 2, original delivery + create retry → run 1 - create K or send s1 retried with a changed payload → invalid_request - full-access create → runtime_mode_escalation_denied - reader create → capability_denied - no proof, Bearer, forged, another key's proof → 401 DPoP - replayed proof → 401 DPoP; browser origin → 403 - C after its 1m lifetime → 401 - A revoked → 401; B unaffected ``` Real-orchestrator regression: `ExternalMcpService.orchestrator.fork.test.ts` (owner elevates a thread under a used key; lost result for create, send, interrupt, idle interrupt; owner mode change during a running or starting turn; a send joins only its vetted attempt, also across an owner restart; dispatch refuses a send vetted under older modes; an owner raise that wins the lock mid-create keeps the prompt from starting). Auth: `ExternalMcpServer.auth.fork.test.ts` (real session store and DPoP verifier). Schema: `ForkSchema.fork.test.ts` adds the interrupt pin to an existing request table.

One upstream doc, `orchestrator-mcp-server.md`, is corrected to the shipped provider credential lifetime. Probe from the guest with the read-only external credential: ```diff + /api/mcp/external → 200 - provider /mcp, DPoP or Bearer → 401 invalid_mcp_credential - /api/auth/clients, pairing-links → 403 insufficient_scope - /api/auth/pairing-token → 403 insufficient_scope ! /api/auth/websocket-ticket → 200 ``` The ticket route only requires authentication upstream; this PR leaves it unchanged. Every RPC on that socket requires a scope ([`RpcAuthorization.ts`](https://github.com/RSI-Software/t3code-hyprws/blob/77023d822ba173f4be58619469f2ae16179f0750/apps/server/src/auth/RpcAuthorization.ts)). Live probe through that ticket, same branch server, a fresh read-only external grant: ```diff + POST /api/auth/websocket-ticket → 200, ticket issued + GET /ws?wsTicket=…&orchestrationProtocol=2 → socket open - server.getConfig → EnvironmentAuthorizationError orchestration:read - orchestration.subscribeShell → EnvironmentAuthorizationError orchestration:read - subscribeAuthAccess → EnvironmentAuthorizationError access:read - orchestration.dispatchCommand → EnvironmentAuthorizationError orchestration:operate - terminal.open → EnvironmentAuthorizationError terminal:operate - after revoke: websocket-ticket → 401 ``` No call returned a value or a stream chunk. Payloads were valid but aimed at ids that do not exist, so even an accepted call could touch nothing. Opening the socket records only the session's own connection, as for any client. <details> <summary>Probe method</summary> | Item | Value | | --- | --- | | Server | `657bd5c` source, own `.t3`, `192.168.122.1:38917` | | Client | host Node script, own P-256 key; DPoP with `ath` | | Grant | `--mcp-project` one project, no `--mcp-coordinate` | | Output | reply tag, exit tag, scope, error tag; never the token or ticket | Effect RPC decodes a payload before the scope check, so an invalid payload fails decoding first. The probe sends valid payloads so the scope check is what answers. </details> ## Verification ```text npx tsc --noEmit -p apps/server → exit 0 vp test run <ForkSchema, mcp/external, ThreadManagementService, SelectionRestart> → exit 0 (43 tests) vp lint <changed .ts> → exit 0 vp run fork:ci → exit 0 vp run build (apps/server) → exit 0 ``` Transcript proof, round 4, on an isolated VM. The branch server ran with its own `.t3` and listened on the libvirt bridge only. The guest client was standalone Python with its own P-256 key, and had no T3, host, or provider credentials. ```diff + A, B, C: three grants, three keys, one guest + whoami: each client's own session and policy + one mcp-session-id, two credentials: each call answers as its sender + create K, retry K as sent → same thread + create with prompt → real Codex turn; retry → same run + steer → joins the vetted provider attempt + interrupt → interrupted + steer retry after the run ended → recorded result + owner clears every recorded result while run 3 is live: + interrupt retry → run 2, interrupted; run 3 untouched + steer and send retries → run 2, original delivery + create retry → run 1 - create K or send s1 retried with a changed payload → invalid_request - full-access create → runtime_mode_escalation_denied - reader create → capability_denied - no proof, Bearer, forged, another key's proof → 401 DPoP - replayed proof → 401 DPoP; browser origin → 403 - C after its 1m lifetime → 401 - A revoked → 401; B unaffected ``` Real-orchestrator regression: `ExternalMcpService.orchestrator.fork.test.ts` (owner elevates a thread under a used key; lost result for create, send, interrupt, idle interrupt; owner mode change during a running or starting turn; a send joins only its vetted attempt, also across an owner restart; dispatch refuses a send vetted under older modes; an owner raise that wins the lock mid-create keeps the prompt from starting). Auth: `ExternalMcpServer.auth.fork.test.ts` (real session store and DPoP verifier). Schema: `ForkSchema.fork.test.ts` adds the interrupt pin to an existing request table. The VM run caught that upgrade gap on a round-1 database. | Evidence | Value | | --- | --- | | Head | `77023d822ba173f4be58619469f2ae16179f0750` | | VM run | `657bd5cf7f2`, the last code commit, from source | | Not on the VM | an owner mode change racing a capped send or create; regressions own it | | Harness `extmcp.py` sha256 | `bf43970f…6eef5` | | Transcript sha256 | `4af1dec3…7ccf03` | Transcript: [external-mcp-vm-proof-r4.txt](https://github.com/user-attachments/files/33043476/external-mcp-vm-proof-r4.txt), harness: [extmcp.py](https://github.com/user-attachments/files/33041290/extmcp.py) ### Internal compatibility The external rejection above is a negative test; this section is the positive one. | Check | Result | | --- | --- | | Native Electron | `vp run dev:desktop:agent --home-dir <worktree>/.t3`, head `77023d8`, virtual monitor; backend ready, window connected, threads listed | | Provider MCP call | Codex thread asked to call `t3_project_list`: item `dynamic_tool` `t3-code.t3_project_list` completed, reply `6` = 6 projects | | Provider `/mcp` traffic | initialize `200`, tools/list `200`, tool call `200` | | Existing tests, CI on head | `McpHttpServer`, `McpProviderSession`, `McpSessionRegistry`, `OrchestratorMcpToolkit.integration` in Test Server 1-3 |  Screenshot sha256 `e0c474c6625dc16855e3174840f85d210d032d90bcc08b23479ad8f317ca0712`.

Upstream landed V2 on main as a squash, so a plain merge hit 500 conflicts. This commit takes upstream main's tree and reapplies the fork's own changes since the last preview merge. Fork changes needed to build on the new upstream: - Voice migrations move from 57/58 to 59/60. Upstream now uses 57/58 for webhooks. - effect/unstable/* imports drop the unstable prefix (Effect 4.0.1). - Voice MCP handlers read the caller from the new scope.thread field. - Removed the pending-question tests that rejected other projects. Upstream made those tools work across projects on purpose (pingdotgg#15219). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…ants (#1636) ## Problem An external agent (another machine, another harness) had no safe way to coordinate T3 threads. The only options were the provider-session `/mcp` token or a broad admin credential. ## Change The owner approves a DPoP device grant with an MCP policy instead of scopes. The client then uses `/api/mcp/external`, a second MCP server with its own `t3_external_*` tools. | Aspect | Rule | | --- | --- | | Credential | DPoP device session, scopes `[]` | | Policy | `auth_external_mcp_grants`, keyed by session | | Reads | projects, threads, timelines, waits | | Mutations | create, send/steer, interrupt with `--mcp-coordinate` | | Boundary | granted projects only | | Ceilings | default `approval-required` and `plan` | | Retries | `auth_external_mcp_requests` binds key to request and result | | Lost result | retry recovers the committed message and its run | | Interrupt retry | pins its run, or no run, before dispatch | | Steering | a capped grant joins only the provider attempt it vetted | | Dispatch | refuses a capped send or create prompt once its attempt or the thread modes changed | | Later owner changes | apply to turns that start afterwards, as for any queued message | | Reused key, new payload | `invalid_request` | | Failures | MCP `isError: true`, text led by the code | | Provenance | `createdBy: agent`, `creationSource: mcp` | | Revocation | `t3 auth session revoke` ends it at once | | Isolation | own `Layer.fresh`; `/mcp` is unchanged | ```bash t3 auth device approve <code> --mcp-project <id> --mcp-coordinate ``` The token endpoint also omits `scope` for a scopeless grant. It used to fail with `500` after it had issued the session. ## Head | Commit | Content | | --- | --- | | `77023d822ba173f4be58619469f2ae16179f0750` | head; one docs-only commit | | `657bd5cf7f29aa63a04b13c6421baeac2618afba` | last code commit; the recordings and VM transcript ran here | `git diff 657bd5c 77023d8`: `docs/fork/internals/fork-delta.md` only, +2 −1.

One upstream doc, `orchestrator-mcp-server.md`, is corrected to the shipped provider credential lifetime. Probe from the guest with the read-only external credential: ```diff + /api/mcp/external → 200 - provider /mcp, DPoP or Bearer → 401 invalid_mcp_credential - /api/auth/clients, pairing-links → 403 insufficient_scope - /api/auth/pairing-token → 403 insufficient_scope ! /api/auth/websocket-ticket → 200 ``` The ticket route only requires authentication upstream; this PR leaves it unchanged. Every RPC on that socket requires a scope ([`RpcAuthorization.ts`](https://github.com/RSI-Software/t3code-hyprws/blob/77023d822ba173f4be58619469f2ae16179f0750/apps/server/src/auth/RpcAuthorization.ts)). Live probe through that ticket, same branch server, a fresh read-only external grant: ```diff + POST /api/auth/websocket-ticket → 200, ticket issued + GET /ws?wsTicket=…&orchestrationProtocol=2 → socket open - server.getConfig → EnvironmentAuthorizationError orchestration:read - orchestration.subscribeShell → EnvironmentAuthorizationError orchestration:read - subscribeAuthAccess → EnvironmentAuthorizationError access:read - orchestration.dispatchCommand → EnvironmentAuthorizationError orchestration:operate - terminal.open → EnvironmentAuthorizationError terminal:operate - after revoke: websocket-ticket → 401 ``` No call returned a value or a stream chunk. Payloads were valid but aimed at ids that do not exist, so even an accepted call could touch nothing. Opening the socket records only the session's own connection, as for any client. <details> <summary>Probe method</summary> | Item | Value | | --- | --- | | Server | `657bd5c` source, own `.t3`, `192.168.122.1:38917` | | Client | host Node script, own P-256 key; DPoP with `ath` | | Grant | `--mcp-project` one project, no `--mcp-coordinate` | | Output | reply tag, exit tag, scope, error tag; never the token or ticket | Effect RPC decodes a payload before the scope check, so an invalid payload fails decoding first. The probe sends valid payloads so the scope check is what answers. </details> ## Verification ```text npx tsc --noEmit -p apps/server → exit 0 vp test run <ForkSchema, mcp/external, ThreadManagementService, SelectionRestart> → exit 0 (43 tests) vp lint <changed .ts> → exit 0 vp run fork:ci → exit 0 vp run build (apps/server) → exit 0 ``` Transcript proof, round 4, on an isolated VM. The branch server ran with its own `.t3` and listened on the libvirt bridge only. The guest client was standalone Python with its own P-256 key, and had no T3, host, or provider credentials. ```diff + A, B, C: three grants, three keys, one guest + whoami: each client's own session and policy + one mcp-session-id, two credentials: each call answers as its sender + create K, retry K as sent → same thread + create with prompt → real Codex turn; retry → same run + steer → joins the vetted provider attempt + interrupt → interrupted + steer retry after the run ended → recorded result + owner clears every recorded result while run 3 is live: + interrupt retry → run 2, interrupted; run 3 untouched + steer and send retries → run 2, original delivery + create retry → run 1 - create K or send s1 retried with a changed payload → invalid_request - full-access create → runtime_mode_escalation_denied - reader create → capability_denied - no proof, Bearer, forged, another key's proof → 401 DPoP - replayed proof → 401 DPoP; browser origin → 403 - C after its 1m lifetime → 401 - A revoked → 401; B unaffected ``` Real-orchestrator regression: `ExternalMcpService.orchestrator.fork.test.ts` (owner elevates a thread under a used key; lost result for create, send, interrupt, idle interrupt; owner mode change during a running or starting turn; a send joins only its vetted attempt, also across an owner restart; dispatch refuses a send vetted under older modes; an owner raise that wins the lock mid-create keeps the prompt from starting). Auth: `ExternalMcpServer.auth.fork.test.ts` (real session store and DPoP verifier). Schema: `ForkSchema.fork.test.ts` adds the interrupt pin to an existing request table. The VM run caught that upgrade gap on a round-1 database. | Evidence | Value | | --- | --- | | Head | `77023d822ba173f4be58619469f2ae16179f0750` | | VM run | `657bd5cf7f2`, the last code commit, from source | | Not on the VM | an owner mode change racing a capped send or create; regressions own it | | Harness `extmcp.py` sha256 | `bf43970f…6eef5` | | Transcript sha256 | `4af1dec3…7ccf03` | Transcript: [external-mcp-vm-proof-r4.txt](https://github.com/user-attachments/files/33043476/external-mcp-vm-proof-r4.txt), harness: [extmcp.py](https://github.com/user-attachments/files/33041290/extmcp.py) ### Internal compatibility The external rejection above is a negative test; this section is the positive one. | Check | Result | | --- | --- | | Native Electron | `vp run dev:desktop:agent --home-dir <worktree>/.t3`, head `77023d8`, virtual monitor; backend ready, window connected, threads listed | | Provider MCP call | Codex thread asked to call `t3_project_list`: item `dynamic_tool` `t3-code.t3_project_list` completed, reply `6` = 6 projects | | Provider `/mcp` traffic | initialize `200`, tools/list `200`, tool call `200` | | Existing tests, CI on head | `McpHttpServer`, `McpProviderSession`, `McpSessionRegistry`, `OrchestratorMcpToolkit.integration` in Test Server 1-3 |  Screenshot sha256 `e0c474c6625dc16855e3174840f85d210d032d90bcc08b23479ad8f317ca0712`.

…ants (#1636) ## Problem An external agent (another machine, another harness) had no safe way to coordinate T3 threads. The only options were the provider-session `/mcp` token or a broad admin credential. ## Change The owner approves a DPoP device grant with an MCP policy instead of scopes. The client then uses `/api/mcp/external`, a second MCP server with its own `t3_external_*` tools. | Aspect | Rule | | --- | --- | | Credential | DPoP device session, scopes `[]` | | Policy | `auth_external_mcp_grants`, keyed by session | | Reads | projects, threads, timelines, waits | | Mutations | create, send/steer, interrupt with `--mcp-coordinate` | | Boundary | granted projects only | | Ceilings | default `approval-required` and `plan` | | Retries | `auth_external_mcp_requests` binds key to request and result | | Lost result | retry recovers the committed message and its run | | Interrupt retry | pins its run, or no run, before dispatch | | Steering | a capped grant joins only the provider attempt it vetted | | Dispatch | refuses a capped send or create prompt once its attempt or the thread modes changed | | Later owner changes | apply to turns that start afterwards, as for any queued message | | Reused key, new payload | `invalid_request` | | Failures | MCP `isError: true`, text led by the code | | Provenance | `createdBy: agent`, `creationSource: mcp` | | Revocation | `t3 auth session revoke` ends it at once | | Isolation | own `Layer.fresh`; `/mcp` is unchanged | ```bash t3 auth device approve <code> --mcp-project <id> --mcp-coordinate ``` The token endpoint also omits `scope` for a scopeless grant. It used to fail with `500` after it had issued the session. ## Head | Commit | Content | | --- | --- | | `77023d822ba173f4be58619469f2ae16179f0750` | head; one docs-only commit | | `657bd5cf7f29aa63a04b13c6421baeac2618afba` | last code commit; the recordings and VM transcript ran here | `git diff 657bd5c 77023d8`: `docs/fork/internals/fork-delta.md` only, +2 −1. The recordings stand for the head; a reviewer confirms that equivalence. ```diff -| Credential | DPoP device session only; scopes `[]`, so no RPC or route accepts it | +| Credential | DPoP device session only; scopes `[]`, so scope-checked routes and RPCs refuse it | +| WebSocket | `/api/auth/websocket-ticket` needs only authentication; each socket RPC refuses it | ``` ## Recordings Recorded on an isolated QA VM against `657bd5c`.

…ants (#1636) ## Problem An external agent (another machine, another harness) had no safe way to coordinate T3 threads. The only options were the provider-session `/mcp` token or a broad admin credential. ## Change The owner approves a DPoP device grant with an MCP policy instead of scopes. The client then uses `/api/mcp/external`, a second MCP server with its own `t3_external_*` tools. | Aspect | Rule | | --- | --- | | Credential | DPoP device session, scopes `[]` | | Policy | `auth_external_mcp_grants`, keyed by session | | Reads | projects, threads, timelines, waits | | Mutations | create, send/steer, interrupt with `--mcp-coordinate` | | Boundary | granted projects only | | Ceilings | default `approval-required` and `plan` | | Retries | `auth_external_mcp_requests` binds key to request and result | | Lost result | retry recovers the committed message and its run | | Interrupt retry | pins its run, or no run, before dispatch | | Steering | a capped grant joins only the provider attempt it vetted | | Dispatch | refuses a capped send or create prompt once its attempt or the thread modes changed | | Later owner changes | apply to turns that start afterwards, as for any queued message | | Reused key, new payload | `invalid_request` | | Failures | MCP `isError: true`, text led by the code | | Provenance | `createdBy: agent`, `creationSource: mcp` | | Revocation | `t3 auth session revoke` ends it at once | | Isolation | own `Layer.fresh`; `/mcp` is unchanged | ```bash t3 auth device approve <code> --mcp-project <id> --mcp-coordinate ``` The token endpoint also omits `scope` for a scopeless grant. It used to fail with `500` after it had issued the session. ## Head | Commit | Content | | --- | --- | | `77023d822ba173f4be58619469f2ae16179f0750` | head; one docs-only commit | | `657bd5cf7f29aa63a04b13c6421baeac2618afba` | last code commit; the recordings and VM transcript ran here | `git diff 657bd5c 77023d8`: `docs/fork/internals/fork-delta.md` only, +2 −1.

One upstream doc, `orchestrator-mcp-server.md`, is corrected to the shipped provider credential lifetime. Probe from the guest with the read-only external credential: ```diff + /api/mcp/external → 200 - provider /mcp, DPoP or Bearer → 401 invalid_mcp_credential - /api/auth/clients, pairing-links → 403 insufficient_scope - /api/auth/pairing-token → 403 insufficient_scope ! /api/auth/websocket-ticket → 200 ``` The ticket route only requires authentication upstream; this PR leaves it unchanged. Every RPC on that socket requires a scope ([`RpcAuthorization.ts`](https://github.com/RSI-Software/t3code-hyprws/blob/77023d822ba173f4be58619469f2ae16179f0750/apps/server/src/auth/RpcAuthorization.ts)).

The branch server ran with its own `.t3` and listened on the libvirt bridge only. The guest client was standalone Python with its own P-256 key, and had no T3, host, or provider credentials. ```diff + A, B, C: three grants, three keys, one guest + whoami: each client's own session and policy + one mcp-session-id, two credentials: each call answers as its sender + create K, retry K as sent → same thread + create with prompt → real Codex turn; retry → same run + steer → joins the vetted provider attempt + interrupt → interrupted + steer retry after the run ended → recorded result + owner clears every recorded result while run 3 is live: + interrupt retry → run 2, interrupted; run 3 untouched + steer and send retries → run 2, original delivery + create retry → run 1 - create K or send s1 retried with a changed payload → invalid_request - full-access create → runtime_mode_escalation_denied - reader create → capability_denied - no proof, Bearer, forged, another key's proof → 401 DPoP - replayed proof → 401 DPoP; browser origin → 403 - C after its 1m lifetime → 401 - A revoked → 401; B unaffected ``` Real-orchestrator regression: `ExternalMcpService.orchestrator.fork.test.ts` (owner elevates a thread under a used key; lost result for create, send, interrupt, idle interrupt; owner mode change during a running or starting turn; a send joins only its vetted attempt, also across an owner restart; dispatch refuses a send vetted under older modes; an owner raise that wins the lock mid-create keeps the prompt from starting). Auth: `ExternalMcpServer.auth.fork.test.ts` (real session store and DPoP verifier). Schema: `ForkSchema.fork.test.ts` adds the interrupt pin to an existing request table. The VM run caught that upgrade gap on a round-1 database. | Evidence | Value | | --- | --- | | Head | `77023d822ba173f4be58619469f2ae16179f0750` | | VM run | `657bd5cf7f2`, the last code commit, from source | | Not on the VM | an owner mode change racing a capped send or create; regressions own it | | Harness `extmcp.py` sha256 | `bf43970f…6eef5` | | Transcript sha256 | `4af1dec3…7ccf03` | Transcript: [external-mcp-vm-proof-r4.txt](https://github.com/user-attachments/files/33043476/external-mcp-vm-proof-r4.txt), harness: [extmcp.py](https://github.com/user-attachments/files/33041290/extmcp.py) ### Internal compatibility The external rejection above is a negative test; this section is the positive one. | Check | Result | | --- | --- | | Native Electron | `vp run dev:desktop:agent --home-dir <worktree>/.t3`, head `77023d8`, virtual monitor; backend ready, window connected, threads listed | | Provider MCP call | Codex thread asked to call `t3_project_list`: item `dynamic_tool` `t3-code.t3_project_list` completed, reply `6` = 6 projects | | Provider `/mcp` traffic | initialize `200`, tools/list `200`, tool call `200` | | Existing tests, CI on head | `McpHttpServer`, `McpProviderSession`, `McpSessionRegistry`, `OrchestratorMcpToolkit.integration` in Test Server 1-3 |  Screenshot sha256 `e0c474c6625dc16855e3174840f85d210d032d90bcc08b23479ad8f317ca0712`.

…ants (#1636) ## Problem An external agent (another machine, another harness) had no safe way to coordinate T3 threads. The only options were the provider-session `/mcp` token or a broad admin credential. ## Change The owner approves a DPoP device grant with an MCP policy instead of scopes. The client then uses `/api/mcp/external`, a second MCP server with its own `t3_external_*` tools. | Aspect | Rule | | --- | --- | | Credential | DPoP device session, scopes `[]` | | Policy | `auth_external_mcp_grants`, keyed by session | | Reads | projects, threads, timelines, waits | | Mutations | create, send/steer, interrupt with `--mcp-coordinate` | | Boundary | granted projects only | | Ceilings | default `approval-required` and `plan` | | Retries | `auth_external_mcp_requests` binds key to request and result | | Lost result | retry recovers the committed message and its run | | Interrupt retry | pins its run, or no run, before dispatch | | Steering | a capped grant joins only the provider attempt it vetted | | Dispatch | refuses a capped send or create prompt once its attempt or the thread modes changed | | Later owner changes | apply to turns that start afterwards, as for any queued message | | Reused key, new payload | `invalid_request` | | Failures | MCP `isError: true`, text led by the code | | Provenance | `createdBy: agent`, `creationSource: mcp` | | Revocation | `t3 auth session revoke` ends it at once | | Isolation | own `Layer.fresh`; `/mcp` is unchanged | ```bash t3 auth device approve <code> --mcp-project <id> --mcp-coordinate ``` The token endpoint also omits `scope` for a scopeless grant. It used to fail with `500` after it had issued the session. ## Head | Commit | Content | | --- | --- | | `77023d822ba173f4be58619469f2ae16179f0750` | head; one docs-only commit | | `657bd5cf7f29aa63a04b13c6421baeac2618afba` | last code commit; the recordings and VM transcript ran here | `git diff 657bd5c 77023d8`: `docs/fork/internals/fork-delta.md` only, +2 −1. The recordings stand for the head; a reviewer confirms that equivalence. ```diff -| Credential | DPoP device session only; scopes `[]`, so no RPC or route accepts it | +| Credential | DPoP device session only; scopes `[]`, so scope-checked routes and RPCs refuse it | +| WebSocket | `/api/auth/websocket-ticket` needs only authentication; each socket RPC refuses it | ``` ## Recordings Recorded on an isolated QA VM against `657bd5c`.

Part 1 of 3 for MCP sign-in from outside T3 Code (#15219 → #15220 → #15222).
Problem
Every
t3-codeMCP tool assumes the caller is a provider session T3 Code launched for one thread: the invocation scope carries that thread, tools read "the calling thread" to find their target, and thread/project lookups are filtered to the caller's project. An agent that isn't running inside a T3 thread (the goal of this stack) has no thread to fall back on, and in-thread agents can't reach threads in other projects.Fix
Tool parameters choose the target, the credential sets the limits:
threadId/projectId(thread organize/fork/configure/merge-back, queue, pending requests, pull-request link/unlink/list/watch/unwatch, worktree list, thread list/search, scheduled tasks). Omitted targets fall back to the calling thread, so existing agents behave as before.threadAccess.readThread,OrchestratorMcpService.loadScopedThread).t3_thread_update), pull-request link/unlink/watch/unwatch, and scheduled task update/delete (a capped caller can't rewrite a full-access task's prompt). Interrupts are included. A thread caller also needs its own live run before it writes to any other thread, so a provider token that outlived an unclean session stop can still read but not reach across threads. A thread changing itself is unaffected.schedule_taskchecks a caller-named project exists before recording a task against it.t3_thread_searchstill defaults to the caller's own project; only a caller outside a thread that omitsprojectIdsearches every project.McpInvocationScopenow has an optionalthreadand aclient(filled in by feat(server): outside agents sign in to the T3 MCP server with OAuth #15220). A caller without a thread must name its targets (target_required), is capped by a runtime-mode ceiling, and getsthread_credential_requiredfrom tools that act as the calling thread (delegate_task,create_threads, task status/cancel, worktree handoff/status, preview, devices). Preview and device capabilities are refused to it outright.orchestrator_capabilities.parentThreadId,inheritedModel,inheritedProviderInstanceIdandt3_thread_list.currentThreadIdbecome nullable for that case. No client reads them.Verification
vp test run src/mcp src/orchestration-v2/ProviderSessionManager.test.ts(server, in a PID namespace): 23 files, 240 tests pass.target_requiredwithout a target, can pin a thread in another project within its ceiling, is denied above it (runtime_mode_escalation_denied), and getsthread_credential_requiredfromdelegate_task; a client launch defaults to the project's model at its ceiling; a caller can't update or delete a scheduled task, rename or interrupt a thread, that runs above its own modes; a thread caller whose run ended can read other threads but not send to, interrupt or rename them.Limits
Thread-only tools still appear in a client's
tools/list(Effect's MCP server filters by the initialize payload, not the credential); their descriptions say they need a T3 thread.Model: Claude Opus 5.5 (1M context) via T3 Code's Claude Code harness.
