🔐 fix: Honor Admin-Panel MCP Allowlist Overrides Without Restart (#13814)
* 🔐 fix: Honor Admin-Panel MCP Allowlist Overrides Without Restart

MCPServersRegistry was built once at boot from getAppConfig({ baseOnly:
true }), freezing allowedDomains/allowedAddresses to YAML. Admin-panel
mcpSettings overrides were ignored by both inspection (addServer/
reinspectServer/updateServer/lazyInitConfigServer) and runtime connection
enforcement (assertResolvedRuntimeConfigAllowed), so a domain allowed only
via the panel failed inspection and never connected.

Make the registry's effective allowlists mutable and refresh them from the
merged admin-panel config: seed at boot, and re-apply on every config
mutation via invalidateConfigCaches -> clearMcpConfigCache. Both inspection
and connection paths read the same getters, so both honor overrides without
a restart. Fail-safe: current allowlists are preserved when the merged read
fails.

* 🛡️ fix: Scope MCP allowlist refresh to global config, fail-safe on DB error

Address Codex P1 review findings on the allowlist-refresh path:

- Tenant-scoped config mutations no longer push one tenant's merged
  mcpSettings into the process-wide registry singleton (read by all MCP
  connection paths), which would leak allowlists across tenants. Only
  global (non-tenant) mutations refresh the registry; tenant mutations
  still evict the config-server cache.
- The refresh read now uses strictOverrides:true so a transient DB error
  throws instead of silently returning YAML base config — preserving the
  last-known allowlists rather than overwriting them with fallback values.
  Adds the strictOverrides option to getAppConfig (default off, no behavior
  change for existing callers).

* ♻️ refactor: Resolve MCP allowlists per-request (tenant-scoped) instead of a global singleton

Supersedes the prior global-mutation approach. MCP allowlists live in
mcpSettings, which is tenant/principal-scoped admin config, so a process-wide
singleton value is the wrong model — it caused cross-tenant bleed and stale
reads.

Instead, inject a resolver (from the app layer, where the merged config lives)
that the registry calls per inspection and per connection. It reads the ALS
tenant context via getAppConfig and accepts the acting user so user/role-scoped
overrides resolve; config-source inspection (no user) resolves at tenant scope.
Falls back to the YAML base allowlists when no resolver is set or the lookup
fails, so a transient error fails to the operator baseline rather than
disabling the allowlist.

Removes the now-unnecessary setAllowlists / boot-seed / invalidateConfigCaches
refresh / getAppConfig.strictOverrides machinery.

* 🔒 fix: Scope config-source cache by allowlist; resolve OAuth allowlists per-request

Address Codex review of the per-request resolver:

- Config-source cache key now folds in the resolved allowlists, not just the
  raw-config hash. Inspection results became allowlist-dependent, so without
  this a tenant whose allowlist rejects a URL could poison the shared key with
  an inspectionFailed stub for a tenant that allows it (and vice versa). The
  tenant-scoped allowlist is resolved once per ensureConfigServers pass and
  threaded through the cache key + inspection.
- The two remaining request-time OAuth allowlist reads now use the merged
  config instead of the YAML base getters: the fallback OAuth-initiate path
  (routes/mcp.js) via resolveAllowlists, and OAuth revocation
  (UserController.maybeUninstallOAuthMCP) via the request's already-merged
  appConfig.mcpSettings. Without this, an OAuth endpoint allowed only by an
  admin-panel override was rejected while inspection/connection allowed it.

*  test: Update MCP OAuth registry/config mocks for per-request allowlists

CI fix for the Finding-12 change. The OAuth-initiate route now calls
registry.resolveAllowlists() and the revocation path reads the merged
appConfig.mcpSettings, so the affected specs' mocks were asserting the old
base-getter values:
- routes/__tests__/mcp.spec.js: add resolveAllowlists to the registry mock.
- UserController.mcpOAuth.spec.js: provide mcpSettings on the getAppConfig
  mock so revokeOAuthToken still receives the expected allowlists.

* 🧪 test: e2e proof that admin-panel MCP allowlist override takes effect

Adds a Playwright mock-harness spec for #13809. A URL-based MCP fixture
(e2e-http, streamable-http SDK server) boots inspectionFailed because its
origin is omitted from the YAML mcpSettings.allowedDomains; the spec adds that
origin via an admin config override (PUT /api/admin/config/user/:id) and
asserts the server reinitializes — exercising the real resolver path through
the backend + DB. Before the fix, reinspection used the frozen YAML allowlist
and the server stayed unreachable.

- e2e/setup/fake-mcp-http-server.js: streamable-HTTP MCP fixture (health GET /).
- e2e/playwright.config.mock.ts: boot the fixture as a second webServer.
- e2e/config/librechat.e2e.yaml: mcpSettings.allowedDomains (excludes 127.0.0.1)
  + the e2e-http server.
- e2e/specs/mock/mcp-allowlist-override.spec.ts: login → baseline reinit fails →
  apply override → reinit succeeds.
