Summary

Fixes the four MCP console surfaces in #2579 that gave poor or misleading feedback.

  • Directory list and Show more. Rows render at once and logos fill in afterwards from a budgeted host-side icon cache that remembers failed logos instead of re-fetching them. A failed Show more shows inline with Retry, and paging appends without duplicates.
  • Directory search. Earlier results stay on screen under "Searching for '…'", and a superseded request is aborted. Featured servers that match answer at once, and stay visible if the directory is slow or times out. The host bounds search, featured lookups and icons, and answers with typed failures (registry_timeout, registry_unavailable) that the console shows in plain words with Retry; raw harness error text no longer reaches the screen. Install is disabled in the entry pop-up while its server lookup has failed.
  • OAuth sign-in. A per-flight sign-in watcher survives React StrictMode, re-checks when the tab regains focus or visibility, shows elapsed time and Check now, confirms success with a toast carrying the tool count, and ends in a clear timed-out state with Try again after 5 minutes.
  • Agent access on an MCP server page. "Edit agents" is replaced by an inline "Available to" editor that shares the Skills agent-access list and save loop. Reach is reported per agent from the same grant checks the harness uses, so registry installs no longer over-report the whole roster; blocked agents show a reason, and removing inherited access warns first. A tools edit made outside the harness path now rebuilds that agent's runtime.
  • Secrets in Debug output. ObservedServers (the MCP call observer's record of configured credentials, used for scrubbing) no longer derives Debug, so those values cannot reach a log line through it. This was the non-blocking review note on refactor(skills,mcp): move skills and MCP machinery onto tinyskills and tinymcp (#2576) #2580.

Closes #2579

API Or Behavior Changes

  • Host MCP registry routes return typed failures (registry_timeout, registry_unavailable) instead of a raw harness error string, and search, featured lookups and icon fetches each run under a time budget.
  • Icons are served through a host-side cache with negative caching of failed fetches.
  • The MCP server route reports each agent's access to the server (granted, inherited or blocked, with a reason); the console edits it in place.
  • Editing an agent's tools outside the harness path rebuilds that agent's runtime.
  • No public Rust API changes outside the server ops and MCP modules.

Tests

Run locally on the branch rebased onto main (c589a64):

  • cargo fmt --all -- --check
  • cargo clippy --locked --all-targets -- -D warnings
  • cargo clippy --locked -p opencompany-core --no-deps --features openhuman --all-targets -- -D warnings, and the same with --features openhuman,mcp
  • cargo build --locked --bin opencompany
  • cargo test --locked -p opencompany-core --features openhuman --tests: 8735 passed, 0 failed
  • Console: npm run typecheck, typecheck:e2e, typecheck:unit; npm test: 6375 passed
  • Playwright against the real host with a mock registry: mcp-agent-access, mcp-directory-feedback, mcp-signin-feedback (10/10 passed)

New coverage: host unit tests for agent access, typed directory failures, the icon cache and the tools-edit runtime rebuild; console unit tests for popular-match search and its fallback; e2e for sign-in feedback, directory paging/search and agent access.

A wider --features openhuman,mcp --lib run, which CI does not run, shows two failures in code this branch does not change (no diff under harness/ or the inference ops): every_registered_tool_is_declared (harness belt) and a_company_key_on_a_staging_host_is_presented_to_staging (inference ops).

Documentation

docs/modules/mcp.md (sign-in watch, agent access) and docs/modules/mcp-registry.md (directory budgets, typed failures, icon cache, featured-first search) are updated.

Summary by CodeRabbit

  • New Features

    • Added per-agent MCP server access details and an editor for managers to grant or revoke access, with clear indicators when access is inherited or blocked.
    • Improved browser sign-in feedback with progress updates, automatic checks, manual rechecks, and retry options after a timeout.
    • Enhanced the MCP directory with search, featured-result fallbacks, pagination, and retry options for slow or failed requests.
  • Improvements

    • Directory failures now show clearer messages, and server icons can load in the background.
    • Agent tool changes can take effect without waiting for a new turn in supported cases.
    • MCP server reachability now reflects effective access grants; registry-only installs no longer imply that every teammate can reach the server.

ObservedServers holds every configured MCP credential for scrubbing; a
derived Debug would print them in any log line that formatted it. Nothing
formats it, so the derive is dropped rather than replaced.

📝 Walkthrough

Walkthrough

The PR adds per-agent MCP access reporting and editing, improves registry read and directory feedback, and changes OAuth sign-in polling and confirmation. It also rebuilds runtimes after qualifying agent tool edits and updates associated tests and documentation.

Changes

Per-agent MCP access

Layer / File(s) Summary
Access projection and reachability
crates/opencompany-core/src/server/ops/mcp*
MCP rows now include an access grant and per-agent access states, grant/revoke tools, and reachability derived from effective grants. Registry installs use registry-specific grant keys.
Console access editor and shared agent list
frontend/src/api/types.ts, frontend/src/components/agent-access-list.tsx, frontend/src/lib/agent-access-*, frontend/src/lib/mcp-scope.ts, frontend/src/views/mcp/*, frontend/src/views/skills/SkillPage.tsx
The MCP page now displays and edits per-agent access. Saves proceed in order and report partial failures. The Skills view uses the shared agent list and save helper.
Runtime rebuild after tool edits
crates/opencompany-core/src/server/ops/team_agent*
Tool edits trigger a runtime rebuild on non-harness cognition paths when in-place rebuilding is available. Tests cover tool-list and null edits, and confirm name edits do not rebuild.
Observed-server derive update
crates/opencompany-core/src/mcp/observe.rs
The private ObservedServers type no longer derives Debug; PartialEq and Eq remain.

Registry reliability and directory feedback

Layer / File(s) Summary
Bounded registry reads and icon caching
crates/opencompany-core/src/server/ops/mcp_registry*
Search and lookup reads use budgets and typed timeout or unavailable responses. Icon fetches share pending work and cache successful and failed results.
Directory search, pagination, and recovery
frontend/src/api/mcp-registry.ts, frontend/src/hooks/use-mcp-directory.ts, frontend/src/lib/mcp-registry.ts, frontend/src/views/connections/McpRegistryBrowser.tsx
Search requests can be aborted. The directory retains prior rows while loading, merges featured matches, and offers retry for search and pagination failures. Failed detail lookups disable installation until retry succeeds.
Registry tests and documentation
crates/opencompany-core/src/server/ops/mcp_registry/*tests.rs, frontend/test/e2e/mcp-directory-feedback.spec.ts, frontend/test/unit/mcp-directory-feedback.test.ts, frontend/test/unit/mcp-registry-degrade.test.ts, frontend/test/unit/mcp-yours-discover.test.ts, docs/modules/mcp-registry.md
Tests cover registry failures, icon caching, search, pagination, cancellation, fallback, and lookup retry. Documentation describes the related directory behavior and time limits.

OAuth sign-in feedback

Layer / File(s) Summary
Sign-in watcher and dialog feedback
frontend/src/lib/mcp-sign-in-watch.ts, frontend/src/views/connections/McpServersSection.tsx, frontend/src/views/mcp/McpConnectDialog.tsx
Sign-in checks repeat on a timer and on focus or visibility changes. The dialog shows check timing, timeout state, and check/retry actions. A successful probe reports the connected server and tool count.
Sign-in validation and docs
frontend/test/e2e/mcp-signin-feedback.spec.ts, frontend/test/unit/mcp-sign-in-watch.test.ts, frontend/test/unit/mcp-signin-strictmode.test.ts, docs/modules/mcp.md
Tests cover polling, focus checks, StrictMode, timeout, manual checks, retry, and success feedback. Documentation describes the polling and timeout behavior.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 673f9

The new server-specific access editor can overwrite a concurrent permission change because it saves an agent’s complete tool list. This can unintentionally restore access to another server. Changes still require administrator authority and remain bounded by company and desk permissions. Runtime refresh improves, but review coverage is incomplete.

Retained concerns

  • Medium · security · inferred: The new server-specific editor submits complete tool lists computed from an earlier roster snapshot. Two administrator views can therefore undo each other’s revocations: with access to servers A and B, revoking B and then saving a stale revocation of A restores B. The backend lock serializes both writes but does not preserve the first revocation. The underlying whole-list contract predates this PR; the new independently scoped server controls expose it to cross-server permission changes that are outside the displayed edit’s intent.

Security review details

Security Blast Radius

  • inferred — A stale save can affect the selected agent’s entire requested tool list, including permissions unrelated to the displayed server. A multi-agent save can affect several roster agents. Effective authority remains bounded by that company’s grants and desk narrowing; the inspected path does not establish cross-company or host-level privilege expansion.

Security Findings and Attack Paths

  • inferred — Concurrent authorized server edits can restore a previously revoked grant through stale whole-list replacement. An agent subsequently receiving that restored grant may regain the corresponding tool capability. This is an inferred permission-consistency failure, not an observed exploit or a member-to-administrator bypass.

Trust Boundaries and Controls

  • observed — Client-submitted tools are not authorized by the UI alone. The backend reloads the company record under its write lock, rechecks roster identity, and requires administrator authority whenever tools are supplied. These checks constrain the stale-write concern but do not validate the freshness of its permission snapshot.

Resilience and Maintainability Implications

  • observed — The shared save loop explicitly contains partial failures by stopping at the first refused write and reporting which updates completed. This avoids presenting a failed multi-agent save as atomic success, but does not protect successful writes from stale permission snapshots.

Hardening Proposals

  • proposed — Use a revision-checked whole-tools update, or a server-specific mutation that recomputes the change from current permissions under the company lock. Reject conflicting snapshots rather than silently restoring unrelated grants.

The PR includes changes outside issue #2579. crates/opencompany-core/src/mcp/observe.rs removes Debug from ObservedServers for the separate #2580 review note. crates/opencompany-core/src/server/ops/team_agent.rs adds runtime rebuild behavior for non-harness tool edits, which is not an acceptance criterion for #2579's directory, sign-in, or per-server access feedback.
