fix: gate MCP user tokens on owner-scoped personal RBAC (#27945)
Re-gates every `mcp_server_user_tokens` dbauthz method from `rbac.ResourceDeploymentConfig` onto owner-scoped personal actions, mirroring the `external_auth_links` prior art. These are per-user credential rows, not deployment config, and the old gate forced every call site to elevate with `dbauthz.AsSystemRestricted`. ## Summary - Reads gate on `ActionReadPersonal` and writes on `ActionUpdatePersonal` against the token owner (`MCPServerUserToken.RBACObject()` derives from `user_id`). The id-keyed refresh and refresh-failure mutations resolve the owner via a `GetMCPServerUserTokenByID` prefetch inside dbauthz; the mutation queries cannot retarget a row's owner, so there is no fetch-authorize race. - All seven token-path `AsSystemRestricted` elevations in `coderd/mcp.go` and all four in chatd are removed along with their `//nolint:gocritic` markers; handlers use the request actor. - The daemon-wide chatd subject keeps only `ActionReadPersonal` on `ResourceUser`. Background token refresh and failure persistence use a new per-user `AsChatdTokenOwner` subject holding only user-level `ActionUpdatePersonal` scoped to the token owner (both mutations resolve the row via the underlying store, so the subject needs no read grant), and chatd never holds site-wide personal-write access. `TestAsChatd` pins the complete `ResourceUser` action set and `TestMCPServerUserTokensAuth` exercises both subjects against the real authorizer. - New strict-authorizer test (`rbac.NewAuthorizer` against real rows): owner passes get/upsert/delete, a stranger fails, and an org admin of another org fails. No user-visible behavior change. Stacked on #27944. Completes the MCP org-separation stack. Closes https://linear.app/codercom/issue/CODAGT-806 UAT: regression pass on a dogfood instance: OAuth2 connect redirect, member list/status with redaction, self-scoped disconnect (cannot touch another user's token), end-to-end chat MCP tool invocation, and lower-stack audit/ACL smoke checks. > Mux (AI agent) authored this PR on Mike's behalf. <!-- mux-attribution: model=claude-fable-5 thinking=high --> |

feat: add group and user ACLs to MCP server configs (#27944)
Adds group and user ACLs to org-scoped MCP server configs so
organizations can restrict specific MCP servers to subsets of members,
mirroring the template ACL pattern.
## Summary
- Migration adds `group_acl`/`user_acl` JSONB columns (nested `{"<id>":
{"permissions": [...]}}` shape) and seeds every existing config with its
organization's Everyone group read entry (the Everyone group ID equals
the org ID), so member access is unchanged by default. Creation seeds
the same entry.
- The blanket org-member read grant from the base PR is replaced by ACL
evaluation: Rego requires org membership for every ACL grant, and
`GetAuthorizedMCPServerConfigs` compiles ACL-aware SQL filters.
- New `ActionShare` (org admins) gates `GET|PATCH
/api/experimental/organizations/{organization}/mcp-servers/{mcpserverconfig}/acl`
(nested under the organization like the rest of the config surface).
PATCH validates principals against the config's organization, merges
sparse updates under a row lock, stamps `updated_by`/`updated_at`, and
is audited as a Write with `Old` captured before authorization. A config
deleted concurrently between the middleware fetch and the locked
re-fetch is concealed as 404, matching the update and delete handlers.
ACL columns are tracked in the audit table.
- ACL management is available in all editions (no enterprise
entitlement), documented in the MCP servers page. Revoking an ACL does
not retro-strip already-selected configs from existing chats; new
selection is blocked at chat create.
- Force On respects the ACL: the forced set is loaded as the chat owner,
so a `force_on` server whose ACL denies the owner never attaches at
create, send, or generation time.
- No rolling-upgrade machinery: upgrades run in scheduled maintenance
downtime, so the migration only backfills existing rows; the API sets
the Everyone read grant explicitly on every insert.
Stacked on #27943. Part of the MCP org-separation stack.
Closes https://linear.app/codercom/issue/CODAGT-712
UAT: verified on a dogfood instance with two members and a custom group:
Everyone-seed default visibility, group grant with Everyone removal
(non-member loses list/fetch/selection), foreign-principal rejection,
non-admin share denial (audited 403 / concealed 404), user_acl restore,
and audited ACL diffs.

feat!: org-scope MCP server configs with RBAC (#27942)
Moves `mcp_server_configs` from deployment scope to organization scope
so each organization fully controls the MCP servers its members can use
with Coder Agents.
## Summary
- Migration: adds `organization_id` (NOT NULL, FK) and keeps existing
rows as the default organization's originals with credentials intact.
Other organizations start with no MCP servers and configure their own;
nothing is copied across organizations. Chats outside the default
organization keep any now-cross-organization `mcp_server_ids` entries;
the runtime already ignores IDs that do not resolve in the chat's
organization, so no data rewrite is needed. Slug uniqueness becomes
`(organization_id, slug)`.
- RBAC: new org-scoped `ResourceMCPServerConfig` with regosql converter
and `GetAuthorizedMCPServerConfigs`; org admins get in-org CRUD, org
members get read (replaced by ACL evaluation in the follow-up ACL PR in
this stack).
- API: all config routes nest under the organization, matching
templates: `POST|GET
/api/experimental/organizations/{organization}/mcp-servers` and
`GET|PATCH|DELETE .../mcp-servers/{mcpserverconfig}` (plus
`oauth2/connect`), resolved by a read-only param middleware that
conceals read-denied and cross-organization access as 404. Two routes
stay on the frozen `/api/experimental/mcp/servers/{mcpServer}` block:
the OAuth2 callback (the redirect URI baked into existing AS-side client
registrations) and `oauth2/disconnect`, which must remain reachable by
users removed from the organization so they can still revoke their token
grant.
- Chat runtime: selection validation and generation resolve configs
strictly by IDs, enabled state, and the chat's organization in SQL;
requested duplicates are normalized; invalid or cross-org IDs are
rejected with the precise ID list. IDs already persisted on a chat are
exempt from message-time rejection so disabling a selected server never
blocks sends; generation skips servers that are no longer usable.
- Frontend: API layer and admin settings pages target the new endpoints.
The admin page manages the default organization's servers; the org
picker is tracked separately (CODAGT-714).
- Security hardening from review: OAuth user grants are additionally
bound to `oauth2_revocation_url` (changing it invalidates grants, and a
racing OAuth callback gets 409 instead of recreating a grant).
Stack-wide SSRF protection for MCP config-directed traffic was split
into its own PR at the top of this stack (#28242) to keep this diff
reviewable; this PR keeps main's existing discovery IP-range guard.
OAuth2 auto-discovery now completes before the config row is inserted: a
failed discovery persists nothing, and there is no provisional row that
concurrent updates could race against.
Two follow-up PRs in this stack were split out to keep this diff
reviewable: #28064 completes the swagger annotations for the moved
routes (main already ships these experimental MCP handlers unannotated),
and #28065 carries hardening fixes and regression pins on top of the
cutover.
- Force On enforcement (landed on main mid-review) is org-scoped: the
forced set is read per chat organization
(`GetForcedMCPServerConfigsByOrganization`), so another organization's
`force_on` server never attaches to a chat.
## Breaking changes (experimental API)
The MCP server config endpoints move from the deployment-scoped
`/api/experimental/mcp/servers` block to organization-nested paths:
`POST|GET /api/experimental/organizations/{organization}/mcp-servers`
and `GET|PATCH|DELETE
/api/experimental/organizations/{organization}/mcp-servers/{mcpserverconfig}`
(plus `oauth2/connect`). The old paths are removed, so API consumers
must supply an organization. Two routes intentionally stay on the frozen
`/api/experimental/mcp/servers/{mcpServer}` block: the OAuth2 callback
(its redirect URI is baked into existing AS-side client registrations)
and `oauth2/disconnect` (must remain reachable by users removed from the
organization). These endpoints are under `/api/experimental`, so no
deprecation window is provided.
## Rolling upgrades
During a rolling deploy, an old replica creating an MCP config can fail
the new `NOT NULL organization_id` constraint until it is upgraded
(reads are unaffected: old binaries' generated queries select their own
column lists). This matches the repo's existing precedent for additive
NOT NULL migrations (000562) and affects only the admin config-create
path in the upgrade window.
Upgrades are expected to run in scheduled maintenance downtime with the
database locked during migration, so the migration ships no
rolling-upgrade compatibility machinery. The down migration deletes
organization-created configs (their chat references are cleaned by the
000510 delete trigger) and restores deployment-wide slug uniqueness.
Part of the MCP org-separation stack (CODAGT-711 -> CODAGT-717 audit ->
CODAGT-712 ACLs -> CODAGT-806 token RBAC).
Closes https://linear.app/codercom/issue/CODAGT-711
UAT: validated end to end on a two-org dogfood deployment, including a
real pre-migration to post-migration upgrade, cross-org isolation
(404s), same-slug-two-orgs, chat selection gating, and a live MCP tool
call through the org-scoped generation path. The migration was later
revised to keep existing rows in the default organization only (no
per-organization copies); that revision is covered by the migration test
suite.

feat: revoke MCP server OAuth grants at the provider on disconnect (#27300)
Closes [CODAGT-805](https://linear.app/codercom/issue/CODAGT-805/revoke-oauth-grants-at-the-source-for-mcp-servers). The experimental MCP server OAuth2 disconnect endpoint previously deleted only the stored token row, leaving the grant active at the OAuth provider. This PR adds provider-side token revocation while keeping local disconnect independent of provider availability. ## Changes - Add `mcp_server_configs.oauth2_revocation_url` in migration `000547`. The value can be configured manually, discovered from RFC 8414 metadata, and managed through the MCP server settings UI. Non-admin responses redact it with the other OAuth2 fields. - Revoke the refresh token first through the RFC 7009 endpoint, then fall back to the access token only for `unsupported_token_type`. Public clients send `client_id`; confidential clients use `client_secret_basic`. - Delete the local token transactionally before best-effort provider revocation. Callers without a token receive the same response for hidden and nonexistent config IDs, and provider failures return a generic warning without exposing provider response bodies. - Require HTTPS revocation endpoints except for HTTP loopback URLs. Redirects must preserve the POST and remain on the configured origin. Redirect errors omit provider-controlled paths and query strings so reflected token material cannot enter logs. - Treat `200 OK` and `204 No Content` as completed revocations. `202 Accepted` remains a failure because it does not confirm completion. - Prevent an in-flight refresh from recreating a token deleted by disconnect. Refresh persistence now uses an optimistic update keyed by token ID and `updated_at`; only the OAuth callback can create a token row. Refresh conflicts reload the current row or clear in-memory auth when disconnect deleted it. - Return `{token_revoked, token_revocation_error}` from disconnect, while retaining SDK compatibility with the legacy `204` response. The UI surfaces provider revocation failures as warning toasts. - Document revocation endpoint discovery, HTTPS requirements, and best-effort disconnect behavior. No token or no configured revocation URL returns `token_revoked: false` without an error, so disconnect remains idempotent. > Updated by Mux, an AI coding agent, on Mike's behalf. |

feat: handle revoked OAuth grants for MCP servers gracefully (#27264)
Closes [CODAGT-792](https://linear.app/codercom/issue/CODAGT-792/handle-revoked-oauth-grants-for-mcp-servers-gracefully). When a user revokes an upstream OAuth grant for an MCP server used by Coder Agents, Coder kept treating the cached token as valid: `invalid_grant` refresh failures were logged and swallowed, the dead bearer token kept being attached, the list endpoints re-attempted the refresh on every call, and the UI kept showing the server as authenticated. ## Changes Backend, mirroring the `external_auth_links` prior art: - New migration adds `mcp_server_user_tokens.oauth_refresh_failure_reason`. `UpsertMCPServerUserToken` clears it, so completing the OAuth flow again recovers the row. - New `MarkMCPServerUserTokenRefreshFailure` query records the failure and clears all token material, guarded by an `updated_at` optimistic lock so a stale failure never clobbers a concurrently refreshed token (on a lock miss the winner's row is used). - `mcpclient.IsPermanentRefreshError` classifies `*oauth2.RetrieveError` codes: only `invalid_grant` and `bad_refresh_token` are permanent. Client/config errors (`invalid_client`, `unauthorized_client`, ...) stay transient for the user row since reconnecting cannot fix them. - chatd token refresh and the MCP list/get endpoints persist permanent failures, return cleared tokens for the in-flight request, and skip provider calls for already-failed rows. - `buildAuthHeaders` no longer attaches an Authorization header for failed tokens, so chat degrades by omitting that server's tools instead of sending a dead bearer. API and UI: - No new API surface. A permanently failed token simply reports `auth_connected: false`, so the existing "Auth" button and "Not authenticated" tooltip appear and the user re-runs the same OAuth flow to recover. An earlier revision added an `auth_status` enum (`connected` / `not_connected` / `reconnect_required`) with a dedicated "Reconnect" button; it was collapsed to keep the API minimal since both states lead to the identical re-auth action. Out of scope (follow-up): typed 401-on-connect detection and forced refresh. mcp-go exposes no stable typed 401 signal in the static-header path, so a revocation while the access token still looks valid locally stays undetected until expiry triggers a refresh. ## Testing - Unit and integration tests: classifier, chatd refresh paths (permanent/transient/race/persist-failure), API endpoints (revoked, transient, no-retry caching, re-auth recovery, stale-lock), dbauthz, dbcrypt, migrations. - Dogfood UAT against a dev instance with a mock IdP returning `invalid_grant`: revoked grant detected on refresh and persisted once (no repeated IdP calls), chat with the revoked server selected completes with the server's tools omitted, and re-auth restores the connected state. > This PR was authored by Mux, working on Mike's behalf. |

feat: allow approved external MCP tools in root plan mode (#24509)
## Summary
Allow root plan-mode chats to use MCP tools from external servers that
an admin has explicitly approved for plan mode. Workspace MCP and
plan-mode subagents remain blocked.
## Problem
`chatd.go` excluded every MCP tool when `isPlanModeTurn` was true, so
planning had no access to tools like docs search, ticketing, etc.
Lifting that guard wholesale was unsafe: `mcp_server_configs` already
has centralized admin governance, but workspace-local MCP (discovered
from agent `.mcp.json`) does not, and subagents use a narrower trust
boundary.
## Fix
Add an admin-controlled per-server `allow_in_plan_mode` flag (default
`false`) and gate plan-mode MCP access on it.
### Backend / schema
- New migration `000472_mcp_server_allow_in_plan_mode.{up,down}.sql` and
matching fixture update.
- `mcpserverconfigs.sql` + generated code: persist and read the new
column.
- `codersdk/mcp.go`: thread the field through `MCPServerConfig`,
`Create*`, and `Update*` request types.
- `coderd/mcp.go`: validate, persist, and return the flag in
get/list/create/update handlers.
### chatd
- `coderd/x/chatd/chatd.go`: pre-filter selected external MCP configs by
`AllowInPlanMode` before calling `mcpclient.ConnectAll` on plan-mode
root turns. Workspace MCP discovery is skipped entirely on plan-mode
turns.
- Single helper decides whether a tool is available in plan mode, used
both at construction and for active-tool filtering (defense in depth).
Plan-mode subagents, dynamic tools, provider-native tools, computer-use,
and workspace MCP stay unchanged.
- `coderd/x/chatd/prompt.go`: update the root plan-mode overlay text to
match the new boundary.
### UI
- `MCPServerAdminPanel.tsx`: add an explicit toggle ("Allow all tools
from this MCP server in root plan mode") next to the existing governance
controls.
- Regenerated `site/src/api/typesGenerated.ts`.
### Docs
- `docs/ai-coder/agents/architecture.md`: replace the blanket "MCP is
unavailable in plan mode" note with the new root-only, external-only,
admin-approved policy. Explicitly call out that workspace MCP and
plan-mode subagents are still excluded.
### Tests
- Plan-mode visibility (approved vs non-approved external server).
- Plan-mode invocation of an approved external MCP tool.
- End-to-end plan-mode workflow that uses an approved MCP tool and then
reaches `propose_plan`.
- Regressions: workspace MCP still excluded in plan mode; plan-mode
subagents still on the restricted tool boundary; existing tool
allow/deny list filtering still applies.
## Policy precedence
`allow_in_plan_mode` is an **additional** requirement on top of existing
`enabled`, availability, chat-selected / forced server IDs, and tool
allow/deny lists. It approves **all tools on that server** for root plan
mode; a per-tool plan allowlist is deliberately deferred.
## Follow-ups (explicitly out of scope)
- Whether plan-mode subagents should inherit approved external MCP
tools.
- Workspace-local MCP safety model (agent-side `.mcp.json` schema vs. a
coderd-managed workspace MCP config).
## Validation
- `go vet ./coderd/x/chatd/...`
- `go test ./coderd/x/chatd -run 'TestPlan.*|TestMCP.*' -count=1`
- `go test ./coderd/x/chatd -count=1 -timeout 5m` (full chatd suite)
- `make fmt` (no diff)

feat: add model_intent option to MCP server configs (#23717)
Add a per-MCP-server `model_intent` toggle that wraps tool schemas with
a
`model_intent` field, requiring the LLM to provide a human-readable
description of each tool call's purpose. The intent string is shown as a
status label in the UI instead of opaque tool names, and is
transparently
stripped before the call reaches the remote MCP server.
Built-in tools have rich specialized renderers (terminal blocks, file
diffs,
etc.) and don't need this. MCP tools hit `GenericToolRenderer` which
only
shows raw tool names and JSON — that's where model_intent adds value.
The model learns what to provide via the JSON Schema `description` on
the
`model_intent` property itself — no system prompt changes needed.
<details>
<summary>Implementation details</summary>
### Architecture
Inspired by the `withModelIntent()` pattern from `coder/blink`, adapted
for
Go + React. The wrapping is entirely in the `mcpclient` layer — tool
implementations never see `model_intent`.
**Schema wrapping** (`mcpToolWrapper.Info()`): When enabled, wraps the
original tool parameters under a `properties` key and adds a
`model_intent`
string field with a rich description that teaches the model inline.
**Input unwrapping** (`mcpToolWrapper.Run()`): Strips `model_intent` and
unwraps `properties` before forwarding to the remote MCP server. Handles
three input shapes models may produce:
1. `{ model_intent, properties: {...} }` — correct format
2. `{ model_intent, key: val, ... }` — flat, no wrapper
3. Malformed — falls through gracefully
**Frontend extraction**: `streamState.ts` extracts `model_intent` from
incrementally parsed streaming JSON. `messageParsing.ts` extracts it
from
persisted tool call args.
**UI rendering**: `GenericToolRenderer` shows the capitalized intent
string
as the primary label when available, falling back to the raw tool name.
### Changes
- Database: `model_intent` boolean column on `mcp_server_configs`
- SDK: `ModelIntent` field on config/create/update types
- API: pass-through in create/update handlers + converter
- mcpclient: schema wrapping in `Info()`, input unwrapping in `Run()`
- Frontend: extraction from streaming + persisted args
- UI: intent label in `GenericToolRenderer`, toggle in admin panel
- Tests: 6 new tests (schema wrapping, unwrapping, passthrough,
fallback)
### Decision log
- **Option lives on MCPServerConfig, not model config**: Built-in tools
already have rich renderers; only MCP tools benefit from model_intent.
- **No system prompt changes**: The JSON Schema `description` on the
`model_intent` property teaches the model inline.
- **Pointer bool on update request**: Follows existing pattern (`*bool`)
so PATCH requests don't reset the value when omitted.

feat: add MCP server configuration backend for chats (#23227)
## Summary
Adds the database schema, API endpoints, SDK types, and encryption
wrappers for admin-managed MCP (Model Context Protocol) server
configurations that chatd can consume. This is the backend foundation
for allowing external MCP tools (Sentry, Linear, GitHub, etc.) to be
used during AI chat sessions.
## Database
Two new tables:
- **`mcp_server_configs`**: Admin-managed server definitions with URL,
transport (Streamable HTTP / SSE), auth config (none / OAuth2 / API key
/ custom headers), tool allow/deny lists, and an availability policy
(`force_on` / `default_on` / `default_off`). Includes CHECK constraints
on transport, auth_type, and availability values.
- **`mcp_server_user_tokens`**: Per-user OAuth2 tokens for servers
requiring individual authentication. Cascades on user/config deletion.
New column on `chats` table:
- **`mcp_server_ids UUID[]`**: Per-chat MCP server selection, following
the same pattern as `model_config_id` — passed at chat creation,
changeable per-message with nil-means-no-change semantics.
## API Endpoints
All routes are under `/api/experimental/mcp/servers/` and gated behind
the `agents` experiment.
**Admin endpoints** (`ResourceDeploymentConfig` auth):
- `POST /` — Create MCP server config
- `PATCH /{id}` — Update MCP server config (full-replace)
- `DELETE /{id}` — Delete MCP server config
**Authenticated endpoints** (all users, enabled servers only for
non-admins):
- `GET /` — List configs (admins see all, members see enabled-only with
admin fields redacted)
- `GET /{id}` — Get config by ID (with `auth_connected` populated
per-user)
**OAuth2 per-user auth flow:**
- `GET /{id}/oauth2/connect` — Initiate OAuth2 flow (state cookie CSRF
protection)
- `GET /{id}/oauth2/callback` — Handle OAuth2 callback, store tokens
- `DELETE /{id}/oauth2/disconnect` — Remove stored OAuth2 tokens
## Security
- **Secrets never returned**: `OAuth2ClientSecret`, `APIKeyValue`, and
`CustomHeaders` are never in API responses — only boolean indicators
(`has_oauth2_secret`, `has_api_key`, `has_custom_headers`).
- **Field redaction for non-admins**: `convertMCPServerConfigRedacted`
strips `OAuth2ClientID`, auth URLs, scopes, and `APIKeyHeader` from
non-admin responses.
- **dbcrypt encryption at rest**: All 5 secret fields use `dbcrypt_keys`
encryption with full encrypt-on-write / decrypt-on-read wrappers (11
dbcrypt method overrides + 2 helpers), following the same pattern as
`chat_providers.api_key`.
- **OAuth2 CSRF protection**: State parameter stored in `HttpOnly`
cookie with `HTTPCookies.Apply()` for correct `Secure`/`SameSite` behind
TLS-terminating proxies.
- **dbauthz authorization**: All 18 querier methods have authorization
wrappers. Read operations use `ActionRead`, write operations use
`ActionUpdate` on `ResourceDeploymentConfig`.
## Governance Model
| Control | Implementation |
|---------|---------------|
| **Global kill switch** | `enabled` defaults to `false` |
| **Availability policy** | `force_on` (always injected), `default_on`
(pre-selected), `default_off` (opt-in) |
| **Per-chat selection** | `mcp_server_ids` on `CreateChatRequest` /
`CreateChatMessageRequest` |
| **Auth gate** | OAuth2 servers require per-user auth before tools are
injected |
| **Tool-level allow/deny** | Arrays on `mcp_server_configs` for
granular tool filtering |
| **Secrets encrypted at rest** | Uses `dbcrypt_keys` (same pattern as
`chat_providers.api_key`) |
## Tests
8 test functions covering:
- Full CRUD lifecycle (create, list, update, delete)
- Non-admin visibility filtering (enabled-only, field redaction)
- `auth_connected` population for OAuth2 vs non-OAuth2 servers
- Availability policy validation (valid values + invalid rejection)
- Unique slug enforcement (409 Conflict)
- OAuth2 disconnect idempotency
- Chat creation with `mcp_server_ids` persistence
## Known Limitations (Deferred)
These are documented and intentional for an experimental feature:
- **Audit logging** not yet wired — will add when feature stabilizes
- **Cross-field validation** (e.g., OAuth2 fields required when
`auth_type=oauth2`) — admin-only endpoint, will add when stabilizing
- **`force_on` auto-injection** — query exists but not yet wired into
chatd tool injection (follow-up)
- **Additional test coverage** — 403 auth tests, GET-by-ID tests,
callback CSRF tests planned for follow-up
## What's NOT in this PR
- Frontend UI (admin panel + chat picker)
- Actual MCP client connections (`chatd/chatmcp/` manager)
- Tool injection into `chatloop/`
