Stacked on #15464, which is stacked on #15219.

Closes #15131.

Problem

After #15464, an MCP client still couldn't do much of what the app does. It couldn't change settings or keybindings, check providers and quota, run git or PR actions, use terminals, browse host folders to add a project, reorder pins, or open a thread in the user's window.

Change

Domain services own the inbox, diffs, settings, git, terminal, and ordering workflows; MCP handlers authorize calls and map service errors. Anything that changes the environment, runs commands, pushes code, or reveals host paths needs a full-access caller.

  • Settings: t3_environment_read can include the full server settings (credentials redacted) and keybindings. t3_environment_preferences_update accepts any non-credential settings patch, a provider instance toggle or custom models, and keybinding upsert/remove. Credential fields, providerInstances and deviceHosts are rejected and stay in the Settings UI. Reads only return each provider instance's customModels from its opaque driver config, and strip userinfo, query, and fragment credentials from settings URLs, including Cursor's legacy endpoint. Writable endpoints reject embedded credentials. Provider preference edits merge into the latest instance under the settings write lock, preserving concurrent metadata and environment edits. Keybinding rule matching in the keybindings service now compares when expressions and shortcut spellings by meaning, so a listed rule always removes the stored one. The Settings UI gets the same fix.
  • Providers: t3_provider_status (full access, since messages can carry configured URLs) returns install, auth and version per instance, plus rate-limit windows and optional token/cost usage. t3_provider_refresh re-runs the provider checks. There's no login or logout over MCP, since an agent can't complete a sign-in.
  • Git: t3_git_status (read-only, full access because a cold status cache fetches) and t3_git (create/switch branch, pull, and the app's commit/push/open-PR flow). There's no merge or force-push.
  • Pull requests: t3_pull_request_read returns the overview, checks, conversation or a review thread, within a character budget. t3_pull_request_update can comment, reply, resolve or unresolve, request reviewers, and set labels. Reviewer names are matched against the host's candidates. GitHub and Forgejo take logins as given, and on GitLab and Bitbucket an unmatched name must be the host's own id. Merge, close, review approval and title/body edits are left out.
  • Terminals: t3_terminal_list, t3_terminal_read (scrollback with escape codes stripped, full access because output can hold secrets) and t3_terminal_control (open/write/close the same terminals the panel shows). Open attaches to a running shell instead of restarting it. Writes fail if the shell has exited, while the terminal panel still ignores trailing keystrokes.
  • Projects: t3_folder_browse, t3_agent_session_scan and t3_agent_session_import. Creating a new or scratch project already works through t3_project_create and t3_thread_launch.
  • Pin order: t3_thread_organize gets move_pinned and move_active with beforeThreadId. The order-key helpers moved from client-runtime to @t3tools/shared/threadOrderKeys, and client-runtime re-exports them, so web and mobile are unchanged.
  • Open in client: t3_client_open_thread {threadId, panel?} goes through a new subscribeClientIntents stream. The window that acts is the desktop window that most recently reported focus to the preview broker (that history survives reconnects), or failing that a visible, focused window. So an outside agent in a terminal can still bring up a thread. The stream retains at most eight pending intents per client and serializes subscription changes with delivery reporting. Mobile doesn't act on it yet.
  • Fixes the existing t3_environment_preferences_update crash (Service not found: ThreadCommandExecutor), the same one-line wiring as fix(mcp): allow environment preference updates #15337.

Verification

The final service refactors were exercised through 35 actual Codex MCP calls in the isolated dev app: inbox, both diff sources, git/provider/settings reads, pin reorder and restoration, terminal open/write/read/list/close, settings toggle and restoration, keybinding upsert/removal, and credential-bearing endpoint rejection with the original value preserved. The client displayed the terminal output and changed pin order. Concurrent terminal allocation and legacy Cursor endpoint redaction have focused regression coverage in existing test files. Claude's readonly allowlist now includes PR reads.

mcp-created terminal output and reordered pins

settings and keybinding changes verified and restored

  • After the service extraction, Blacksmith passed typecheck for server, contracts, shared, client-runtime and web. The service extraction passed 449 tests across 27 files. The final settings update passed server typecheck, 263 tests across 7 affected files, and scoped lint (zero errors). The MCP, CLI, adapter-allowlist, thread-sort and presentation tests pass, and lint is clean. A new case in core.test.ts checks that settings reads never contain credentials.
  • I ran it live in a dev app, with a full-access Claude Sonnet 5.5 thread calling each tool:

settings and keybinding writes round-trip

git status and pull request reads

terminal open, write, read, list, close

folder browse and agent session scan

pinned order before the move

pinned order after move_pinned

Not verified:

  • t3_git writes (the test checkout was dirty) and t3_pull_request_update, to avoid writing to a real PR.
  • t3_agent_session_import.
  • t3_client_open_thread actually navigating a focused window. It returned delivered: true, but the test browser tab had no focus.
  • The outside-client path over OAuth (feat(server): outside agents sign in to the T3 MCP server with OAuth #15220).
  • A useful interaction recording: preview host disconnects prevented capture; further preview browser use was then disabled by the maintainer. Screenshots were downloaded and inspected. Provider usage probes returned unavailable in the live environment.

Implemented by claude-opus-5-5 in Claude Code; continued and verified by gpt-6-astra in Codex, running in T3 Code.

📝 Walkthrough

Walkthrough

The change adds MCP tools for project, Git, terminal, provider, pull-request, and environment operations. It also adds client-intent delivery, shared thread-ordering utilities and sidebar reordering, and semantic keybinding comparisons.

Changes

MCP tools and settings

Layer / File(s) Summary
Project browsing and agent-session tools
apps/server/src/mcp/toolkits/project/*
Adds paginated folder browsing and agent-session scan and import tools, with full-access checks. Project listing uses a shared pagination helper.
Git status and actions
apps/server/src/git/GitThreadService.ts, apps/server/src/mcp/toolkits/git/*
Adds checkout resolution, status reads, branch and pull actions, and stacked Git actions. MCP handlers check access and map service errors to tool failures.
Thread terminal operations
apps/server/src/terminal/Manager.ts, apps/server/src/terminal/ThreadTerminals.ts, apps/server/src/mcp/toolkits/terminal/*
Adds terminal listing, scrollback reads, opening, writing, and closing. Agent writes can require a running terminal.
Provider status and refresh
apps/server/src/mcp/toolkits/provider/*
Adds provider and quota status, optional usage summaries, and targeted or untargeted refresh operations.
Pull-request reads and updates
apps/server/src/mcp/toolkits/pullRequests/*
Adds bounded pull-request reads and updates for comments, review threads, reviewers, and labels.
Agent settings and keybindings
apps/server/src/serverSettings.ts, apps/server/src/settings/AgentSettings.ts, apps/server/src/keybindings.ts, apps/server/src/mcp/toolkits/environment/*
Adds redacted settings reads and validated settings, provider-preference, and keybinding updates. Keybinding matching compares parsed shortcut and condition meaning.
Toolkit registration and presentation
apps/server/src/mcp/McpHttpServer.ts, apps/server/src/mcp/toolkits/core.test.ts, apps/server/src/mcp/toolkits/worktree/registration.test.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2*, packages/client-runtime/src/t3ToolSummary.ts, packages/shared/src/t3McpToolPresentation.ts

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~90 minutes

Change: Feature

Suggested reviewers: juliusmarminge, t3dotgg

Merge Risk: 🔵 Low · up to 65c59

Some thread-open requests may navigate an unintended tab, and long pull-request responses may return unusable branch or file identifiers. These issues are bounded, but should be fixed or explicitly accepted before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 65c59

The new tools expose consequential host operations and credential-backed repository reads. Full-access checks and settings restrictions provide important containment, but the authority remains broad within an environment. Window-routing identity and failure recovery have not been fully established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — A compromised caller approved for full access can use terminal input and output to exercise host-level authority and encounter host secrets, not merely manipulate application metadata. The inspected gate requires orchestration capability, full-access/default limits, and live-run ownership for thread callers.
  • observed — Pull-request read authority is environment-wide rather than project-isolated. A caller with pull-requests and orchestration capabilities can select another environment thread to resolve a project; the service can route an explicitly hosted reference to another configured checkout and repository on that host. Effective data exposure consequently follows the configured provider account's permissions.

Trust Boundaries and Controls

  • observed — The caller model explicitly separates caller limits from caller-selected targets. Target-mode checks govern thread writes; readThread deliberately loads targets anywhere in the environment. Cross-thread reads alone therefore do not establish a bypass of a project-scoped grant in the inspected model.
  • observed — Window registration and focus reporting use client-supplied routing IDs, while the corresponding RPCs require orchestration read scope. Published intents include the selected target ID. The inspected sources do not bind that routing ID to the authenticated RPC identity; the impact established here is window-selection integrity, not cross-environment access or host privilege escalation.

Resilience and Maintainability Implications

  • observed — Provider preference updates merge editable fields into the current instance under the settings write semaphore, preserving other instance configuration. Settings changes validate before writing, exclude mixed settings/keybinding transactions, and use existing secret rollback and atomic-file persistence paths.
  • observed — Intent publication, window registration, focus updates, and cleanup share a semaphore. Cleanup checks registration object identity before removing a window, preventing an old closing stream from unregistering its replacement after reconnect.

Hardening Proposals

  • proposed — Define the same-environment window-routing trust policy explicitly. If windows are intended to be independently protected, bind registration and focus updates to the authenticated session or connection rather than accepting another window's routing ID. This is a hardening proposal, not a verified vulnerability.

Explanation

Issue #15131 concerns the missing ThreadCommandExecutor dependency for settings updates. The Git, provider, pull-request, terminal, folder/session, pin-order, and client-navigation services and MCP tools do not fix or test that defect. The PR description identifies these as current goals, but no linked issue requires them.

Resolution

Move the independent Git, provider, pull-request, terminal, folder/session, pin-order, and client-navigation workflows and their supporting changes to PRs linked to requirements for those features. Keep this PR focused on the #15131 dependency fix and directly supporting settings changes and tests.

📐 Maintainability & Code Quality | 🟠 Major | 🏗️ Heavy lift

Move reviewer resolution into PullRequestService.

The handler calls detail, conditionally calls reviewerCandidates, resolves host-specific IDs, and then calls requestReviewers. Put that workflow in one domain-service method. The MCP handler should authorize the call and map its typed error. This also gives other transports the same reviewer-resolution behavior. As per coding guidelines, “A transport handler does three things: decode the request, call one service method, and map the service's typed errors to the transport's error. Nothing else.” As per path instructions, “Keep filesystem, Git, process, persistence, naming, multi-step dispatch, retries, and rollback work in services.”
