Summary

Per-account and per-chat settings for the server, with a native settings page for clients that render structured settings and an MCP App panel for clients that support app panels.

Replaces #659 (same change, squashed into one commit on the current main).

Settings model

  • Three layers: the operator configuration (environment and startup presets) stays the floor; account settings (preset, read-only, default project or group, tool groups) apply to every chat of a GitLab account; chat overrides from manage_context apply to the current chat only. Settings only narrow what the operator allows.
  • The caller is derived from the authenticated context: the GitLab user for OAuth, the token's instance for a static token; the chat is the MCP session.
  • Restrictions apply to the tool list and to every call, including direct calls a client never offered: a refused call returns a clear reason and nothing reaches GitLab. Tool, group, read-only and action limits are checked first; only a call they allow has a project or group named by numeric id read from GitLab and checked as its path (an id GitLab does not know is refused; any other lookup failure, such as an expired sign-in, fails the call with GitLab's error and its reauthorization challenge), URL-encoded paths are compared decoded, and destinations are checked too (target_project_id, target_group_id, namespace_id, and the namespace a project is created or forked into, as the group it goes into). A scope of projects reaches no group, so group-targeted calls are refused under it. get_profile, the host's account identity, is never hidden by settings.
  • A scope path must be confirmed by GitLab: update_settings and manage_context set_scope refuse a typo or an unreachable GitLab instead of saving a guessed project or group; an expired sign-in (401, or 403 insufficient_scope) fails with GitLab's error and the reauthorization challenge.
  • An action the operator denied (GITLAB_DENIED_ACTIONS) stays denied under a working scope, also where the scope runs other actions in its place, and a call the scope answers by other requests is validated by the tool's schema first.
  • manage_todos mark_all_done in a scoped chat marks only the scope's pending todos done, a few at a time, and reports how many were marked and which failed; the others stay pending.
  • A project created or forked without a namespace goes into the scope's single group; with no single group, and for a group without a parent, the call is refused. A fork naming both namespace and namespace_path has each checked.
  • The working scope is a focus, not an access boundary: the user sets and clears it, and objects addressed only by a global id (a work item or todo id) are not resolved against it. A project or group access token is the hard boundary GitLab enforces.
  • A listing or search that names no project or group reads the working scope: a global search becomes a search of the scope's group or project, a project listing lists the scope's group (keeping a caller's include_subgroups: false, and the active-projects default of a plain listing unless active or archived is given; or, for a plain listing under a scope made of projects, those projects themselves), a global project search under a project scope answers with the scope projects that match (project search has no projects scope), a snippet title search (instance-wide only) is refused, and a cross-project merge request or vulnerability listing names the scope's target. Project listings and searches (including projects only shared with the scope group), todos and cross-project merge requests are filtered to the scope, reading further GitLab pages until the requested page is full (at most ten pages of 100; a page still short then comes back marked partial with a hint to narrow the listing, and a page starting past those rows answers so without a request). Instance-wide listings read the scope instead: deploy keys those of the scope project, instance audit events the trail of the scope project or group (a group's trail holds its own events, and the result says so), all runners those available to the scope's project or group, the caller's own runners the owned feed (with its cursor) kept to those the scope can use (marked partial past 1000 such runners); scopes with no such form are refused. The projects of a scope made of projects are listed in GitLab's simple representation unless simple is false, read a few at a time and only as far as the requested page needs. The caller's own activity (browse_events user) shows the scope project's events under a project scope and is refused under a group scope or several targets. A namespace argument (labels, wiki, milestones) passes when it names an allowed project or an allowed group, so the scope group itself works also without its subgroups. Under a group scope without subgroups (GitLab's group results always cover them), a global search and a vulnerability listing read the group's results kept to the group and its direct projects, in the tools' own answer shapes (vulnerabilities now carry their project's path); a user search stays as GitLab gives it, and a search of a group with more than 1000 direct projects comes back marked partial. A global search or vulnerability listing is refused under a scope of several projects or groups.
  • A preset's allowed_tools overrides its denied_tools_regex, as documented for profiles; list-tools counts preset tools the same way.
  • A saved preset that was later removed makes the caller read-only (reported by check_connection) instead of failing every call.

Instance routing

  • Every REST call takes its GitLab base URL from one place: the OAuth token's instance, else the instance the server's own token works with now (it follows switch_instance), else GITLAB_API_URL. Tools that built URLs from the startup GITLAB_API_URL (core, files, pipelines, iterations, namespace detection, user search, the generic client used by scope search) now reach the caller's instance; whoami reports and links it the same way, and get_profile reads the account of that instance.

Storage

  • With PostgreSQL session storage (new oauth_account_settings table and migration), account settings live with the sessions, shared by replicas. File session storage keeps them too but serves one server process, as for its sessions.
  • With sessions in memory (the OAuth default) or a local static-token server, they live in ~/.config/gitlab-mcp/settings/ of the user running the server, so saved settings survive a restart. A database package older than the server, which cannot keep settings, falls back to that directory with a warning instead of failing calls.
  • A scope change that does not name the subgroup choice keeps the one saved at write time for a group scope (subgroups included after a project scope or none), so concurrent edits from two chats are both kept.
  • Writes are compare-and-set; concurrent edits of different settings, including different tool groups, are both kept. The local directory needs no lock: each write saves the next numbered generation with an exclusive link and, when another process saved it first, re-reads and checks its version again, so a process that dies or is suspended mid-write never blocks the others or overwrites newer settings. Older generations and temporary files of crashed writers are pruned, the directory is synced after each write, and entries of the wrong shape are skipped; a failed first open of the shared storage is retried by the next request.

Tools and capabilities

  • get_settings / update_settings: the account settings page, advertised through the openai/settings capability. A patch is validated in full before anything is saved; administrator read-only mode cannot be turned off.
  • check_connection: account, GitLab version and tier, restrictions in effect, the number of tools the caller can use (counted as tools/list shows them, including the OAuth token's scopes), and what to do about problems.
  • open_settings_panel: MCP App (ui:// resource, text/html;profile=mcp-app, empty CSP) to search projects and groups, apply a scope to this chat or save it for new chats, and check the connection. Follows the host theme, keyboard accessible, shows GitLab strings as text only, reports success from the settings the server holds after saving. Its preview shows the tool groups off in the chat, including those its preset turns off (manage_context show reports them), and a superseded search finishing late cannot change it. In OAuth mode listing and reading resources needs mcp:resources (refused with an insufficient_scope challenge otherwise), and the panel tool declares both mcp:tools and mcp:resources.
  • find_scope_targets: member projects and visible groups by name, for choosing a scope (needs an api or read_api token scope).
  • manage_context clear_scope: the chat works everywhere, also without the account's default scope; its preset and read-only mode stay. The panel's "Work everywhere in this chat" uses it.
  • The channel gateway forwards resources, so the panel opens through it as well. After a lost link it replays a call when the newest downstream catalog marks the tool read-only, falling back to the tool name for a tool not yet listed or without the annotation; a complete catalog that drops a tool drops its verdict. It forwards the downstream tools/list_changed notification and advertises listChanged, so a host refreshes its catalog after a settings change; it also tells the host to list again after it reconnects downstream.
  • Settings tools are exempt from settings restrictions and from the unreachable-instance check, so a restricted caller can still fix its settings. One answered while GitLab is marked unreachable has the health monitor probe GitLab again, so other tools recover as soon as GitLab answers.
  • The mcp.tools catalog in package.json is regenerated by the release PR (prepare-release.sh), as for every tool; this PR does not edit it.

Behaviour change

manage_context switch_preset, set_scope and reset now affect the current chat only (they used to change the whole server process); reset returns the chat to the account settings. With a static token, switch_instance keeps every chat's read-only mode and preset, clears its scope, and points every session at the new instance before telling it to refresh its tool list.

Known limitation

An account change sends tools/list_changed only to chats served by the replica that saved it. Chats on other replicas apply the new settings from their next request; their clients refresh the tool list on their next list request.

Integration test maintenance

  • Integration runs wait up to 60 s per test; the API timeouts come from .env.test.
  • closing_issues test accepts GitLab's own issue link in both forms (/-/issues/N before 19.0, /-/work_items/N from 19.0).
  • removeLabelIds test sets a known label first instead of relying on earlier tests that skip without enough lifecycle labels.
  • The lifecycle project step reports GitLab's answer when creation fails.
  • The set_scope project test scopes to a project that exists under the test group.

Testing

  • Unit: 6224/6224 (yarn test), lint, and a compile of the build configuration. Every changed line and branch of the source is covered. Tests read and write settings in a temporary directory, never the user's own settings.
  • Database package: 68/68; the migration applied from scratch on PostgreSQL 17, no drift against the Prisma schema, compare-and-set verified live including concurrent writes and a second replica.
  • Integration against GitLab 19.0 EE: 447/447 (yarn test:integration).
  • Instance routing: each tool family's request URL checked against an OAuth caller on another instance; base URL selection checked for OAuth, switch_instance and the configured fallback.
  • Settings panel exercised in jsdom against a simulated MCP Apps host (handshake, theme, untrusted strings, save and cancel, expired sign-in, unreachable GitLab).
  • Multi-replica test: two users and two chats stay apart, settings survive a restart, concurrent edits from two replicas are kept.
  • Not verified: rendering of the settings page and the panel inside desktop clients.

Closes #637

Summary by CodeRabbit

  • New Features

    • Added persistent account settings and per-chat overrides for presets, read-only mode, tool access, and working scope.
    • Added a settings panel and tools to manage configuration, search projects and groups, check connection health, and clear the current chat’s scope.
    • Tool availability and actions now reflect configured access rules and working scope; clients are notified when available tools change.
    • GitLab requests follow the active instance, including after switching instances.
  • Documentation

    • Added settings guidance and clarified which context preferences persist across chats and instance switches.

…nnection panel

Per-account and per-chat settings on top of the operator configuration,
a native settings page and an MCP App panel to manage them.

- Settings layers: the operator configuration stays the floor; account
  settings (preset, read-only, default scope, tool groups) apply to
  every chat of a GitLab account; manage_context overrides apply to the
  current chat only. The caller comes from the authenticated context.
- Restrictions apply to the tool list and to every call. The working
  scope is a focus: named targets and destinations are checked,
  targetless listings, searches, project creation and mark_all_done
  are narrowed to the scope or refused, and objects addressed only by
  a global id are not resolved against it.
- Tools: get_settings / update_settings (openai/settings),
  check_connection, open_settings_panel (MCP App resource gated by
  mcp:resources), find_scope_targets and manage_context clear_scope.
- Storage: compare-and-set writes in the durable session storage
  (file or PostgreSQL, new oauth_account_settings table) shared by
  replicas, otherwise in ~/.config/gitlab-mcp/settings.json; an older
  database package falls back to that file.
- Every REST call goes to the caller's GitLab instance: the OAuth
  token's, else the one the server's token works with now, else
  GITLAB_API_URL.
- The channel gateway forwards resources and tools/list_changed and
  replays reads by the downstream catalog's readOnlyHint.
- manage_context switch_preset, set_scope and reset now affect the
  current chat only.
- Tests never touch the user's own settings file; integration tests
  updated for GitLab 19 and a slow test instance.

Closes #637

📝 Walkthrough

Walkthrough

The pull request adds persistent account settings, caller-specific configuration, settings tools and a panel, and policy enforcement for GitLab tool calls. It also adds scoped execution, active-instance API routing, and MCP resource forwarding.

Changes

Account settings and policy

Layer / File(s) Summary
Versioned settings persistence
packages/gitlab-mcp-db/..., packages/gitlab-mcp/src/oauth/storage/*, packages/gitlab-mcp/src/configuration/settings-store.ts
Account settings gain versioned compare-and-set storage in PostgreSQL, OAuth storage backends, and local files.
Caller identity and policy
packages/gitlab-mcp/src/configuration/*, packages/gitlab-mcp/src/registry-manager.ts
Caller identity, tool groups, account and session configuration, and effective tool policies are added.
Context settings and user-facing tools
packages/gitlab-mcp/src/entities/context/*
Context management uses resolved caller configuration. Settings, connection-check, scope-search, and settings-panel tools and handlers are added.
Policy enforcement and scoped execution
packages/gitlab-mcp/src/handlers.ts, packages/gitlab-mcp/src/configuration/scope-*, packages/gitlab-mcp/src/configuration/scoped-*, packages/gitlab-mcp/src/profiles/scope-enforcer.ts
Tool listings and calls apply policy and scope checks. Scoped execution narrows arguments and results, paginates listings, and handles scoped todo updates.
Active-instance routing and gateway forwarding
packages/gitlab-mcp/src/utils/*, packages/gitlab-mcp/src/entities/*/registry.ts, packages/gitlab-mcp/src/channel-gateway/gateway.ts
GitLab requests resolve the active instance URL. The gateway forwards resource requests and tool-list changes and uses catalog read status when classifying calls.
Documentation and validation
packages/gitlab-mcp/docs/*, packages/gitlab-mcp/tests/*, packages/gitlab-mcp/eslint.config.mjs, packages/gitlab-mcp/jest.config.js, packages/gitlab-mcp/package.json

Inline comments:
Review comments at @packages/gitlab-mcp/docs/configuration/settings.md:
- Around line 38-39: Update the documentation near buildPolicy to state that a
chat-level readOnly value can override the account value, while read-only set by
the server administrator or selected preset always applies and cannot be turned
off by a chat.

Review comments at @packages/gitlab-mcp/src/channel-gateway/gateway.ts:
- Around line 152-160: Update recordCatalogReads so a full catalog read (no
nextCursor) removes catalogReads entries from older generations that are absent
from the current catalog. Preserve entries during paginated reads and retain the
existing generation checks when recording tools.

Review comments at @packages/gitlab-mcp/src/configuration/settings-store.ts:
- Around line 80-87: In the settings-loading logic around JSON.parse and
AccountSettingsSchema.safeParse, validate that the parsed root and accounts
value are plain objects before iterating, and validate each entry before reading
record.settings. Reject a non-object root and skip invalid accounts entries with
the existing warning behavior; ensure arrays are not treated as objects.

Review comments at
@packages/gitlab-mcp/src/entities/context/connection-check.ts:
- Line 95: Update the scope reported by the connection check to fall back to the
first project or group when singular project, group, and namespace values are
absent. Reuse a shared scope-resolution helper in this scope assignment and the
access-log path so both report list-based scopes consistently.

Review comments at @packages/gitlab-mcp/src/utils/gitlab-base-url.ts:

- Listings filtered to the working scope read further GitLab pages
  until the requested page is full (at most ten pages of 100), instead
  of filtering one page that may hold no in-scope rows.
- A project scope lists its own projects only for a plain listing;
  with other list filters it pages GitLab's listing, keeping their
  semantics. A scope project that fails for a reason other than 404
  fails the call instead of shortening the list.
- URL-encoded paths ("group%2Fproject") are compared decoded.
- The namespace of a created or forked project is checked as the
  group it goes into, so the scope group itself is allowed also
  without subgroups; a fork without a destination goes into the scope
  group or is refused, like project creation.
- A targetless vulnerability listing names the scope target, and is
  refused for several targets or a group without subgroups.
- get_profile is never hidden by settings.
- Removing a dead settings lock claims it by rename and checks its
  identity, so a fresh lock taken meanwhile is handed back.
- A settings file entry of the wrong shape is skipped, a root that is
  not an object is reported.
- The channel gateway forgets tools a complete catalog no longer
  lists; check_connection and the access log name list scopes; the
  OAuth instance URL is normalized.
- Scoped execution moved to its own module; the settings guide states
  read-only precedence and that file session storage serves one
  process.

Regression tests: scoped page filling and paging, project scope list
filters and failures, encoded paths, creation and fork destinations,
vulnerability listings, the profile exemption, the stale lock race,
settings file shapes, removed gateway tools, list scope reports and
URL normalization.

- A dead settings lock is removed only while the claimed file is still
  old. Linux reuses a freed inode number at once, so a fresh lock could
  carry the dead one's inode and was removed (the stale lock test
  failed in CI on Linux).
- A namespace argument (labels, wiki, milestones) passes when it names
  an allowed project or an allowed group, so the scope group itself is
  usable also without its subgroups.
- browse_events user under a project scope shows that project's events
  and is refused under a group scope or several targets.
- A project scope listing answers with GitLab's simple project fields
  unless simple is false.
- A scoped page that stays short after the bounded read comes back
  marked partial with a hint to narrow the listing.

Regression tests: the lock race with a reused inode, namespace
arguments under a group scope without subgroups, scoped activity
feeds, simple project fields and the partial page.

- A project or group named by numeric id is read from GitLab and
  checked as its path; a working scope holds paths, so numeric ids
  were always refused, also for the scope's own project.
- Instance-wide listings follow the working scope: deploy keys and
  instance audit events read the scope project, all or owned runners
  those available to the scope's project or group; scopes with no
  such form are refused instead of listing the whole instance.
- A preset whitelist overrides its deny pattern, at runtime and in
  the preset tool counts of list-tools, as documented for profiles.
- A scoped page that starts past the 1000 readable rows answers
  partial at once instead of making ten GitLab requests.

Regression tests: numeric ids in and out of the scope, scoped and
refused instance listings, a whitelisted tool its deny pattern
matches, and the page past the readable rows.

Resolving a numeric project or group id for the scope check turned every
failed lookup into an unresolved id, so an expired or revoked token read
as a target outside the working scope and never reached the
reauthorization challenge. Only a 404 keeps the id numeric now; any
other failure fails the call with GitLab's own error.

Regression tests: 401, 403 insufficient_scope, 500 and a non-Error
failure, for a project id and for a namespace read as a group.

🟡 Minor · Check both fork destinations before execution. · scope-targets.ts:94-130

packages/gitlab-mcp/src/configuration/scope-targets.ts:94-130
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Check both fork destinations before execution.

For the accepted manage_project fork arguments, namespace and namespace_path can both be supplied. If namespace is a numeric string, withTargetPaths resolves it, but scopeCheckArgs discards that resolved value when namespace_path already exists. An out-of-scope namespace ID can therefore pass using an in-scope namespace_path, and the original request sends both values to GitLab. GitLab does not define precedence for both fields.

Suggested fix
   if (!isProjectCreation(tool, args) || !hasValue(args.namespace)) return args;
-  const { namespace, ...rest } = args;
-  return { ...rest, namespace_path: rest.namespace_path ?? namespace };
+  return { ...args, namespace_path: args.namespace_path ?? args.namespace };

- Local settings are kept as numbered generations in a directory
  (~/.config/gitlab-mcp/settings/). A write saves the next generation
  with an exclusive link and, when another write saved it first, reads
  the new state and checks its version again. The lock file is gone:
  breaking a dead lock could free the path for a third writer, and a
  writer suspended past the lock lifetime overwrote newer settings
  when it resumed. A temporary file left after a successful save no
  longer reports the write as failed.
- An action the operator denied stays denied under a working scope;
  the scoped emulations ran other actions in its place.
- A project listing keeps the caller's include_subgroups=false under a
  group scope that includes subgroups.
- A global project search under a project scope answers with the scope
  projects that match (project search has no projects scope); a
  snippet title search, instance-wide only, is refused under a scope.
- A fork naming both namespace and namespace_path has both checked.
- Scope lookups for update_settings and set_scope fail with GitLab's
  error on 401 or 403 insufficient_scope, so the call gets the
  reauthorization challenge instead of an unknown-path answer.

Regression tests: a writer resuming after a newer save (failed on the
lock), lost races across accounts, clean-up failures after a save,
denied actions under emulation, subgroup exclusion, project and
snippet searches, both fork destinations, and auth failures of the
scope lookup.

@coderabbitai Re: check both fork destinations (scope-targets.ts, scopeCheckArgs): fixed. The project's namespace of a create or fork is now checked as the group-valued namespace_id while namespace_path stays, so a fork naming both has each destination checked (a numeric namespace is resolved to its path first). Covered by policy tests for an out-of-scope namespace with an in-scope namespace_path and the reverse.

@polaz, I could not verify the fix in the checked-out PR branch. scopeCheckArgs still maps namespace to namespace_path only when namespace_path is absent. When both are supplied, it drops namespace from the scope-check arguments.

I also did not find the two reported regression cases in policy.test.ts. Please confirm that the fix is pushed, then retry verification. This finding remains unresolved.

- A call the scope answers by other requests (a project search, a
  project listing of a scope made of projects, mark_all_done) is
  validated by the tool's schema first: an invalid call is refused
  instead of answered with the scope's projects.
- Tool, group, read-only and action limits are checked before numeric
  targets are resolved, so a call they refuse reaches nothing on
  GitLab and an expired sign-in cannot mask the configured refusal.
- An instance audit listing under a group scope reads the group's own
  trail and says that its projects' events are listed per project,
  instead of being refused.
- A configuration tool answered while GitLab is marked unreachable has
  the health monitor probe GitLab again, so other tools recover as soon
  as GitLab answers. The monitor decides from its own probe; the
  tool's success is not reported as GitLab's.

Regression tests: invalid emulated calls, a read-only call with a
numeric target, the group audit trail, and the probe after a
configuration tool answers.

- Under a group scope without subgroups, a global search and a
  vulnerability listing read the group's results kept to the group
  and its direct projects, instead of being refused: search rows by
  project id, project path or group id, vulnerabilities by their
  project path (now read with each vulnerability). A user search stays
  as GitLab gives it.
- The caller's own runners under a project or group scope keep the
  owned feed and its cursor, filtered to the runners the target can
  use; they were replaced by every runner available to the target.
- A scope made of projects is read a few projects at a time and only
  as far as the requested page needs: the first page of a 50-project
  scope made 50 concurrent requests, now 5.
- switch_instance points every session at the new instance before
  telling them to refresh, so their tool lists are built for the new
  instance's account.

Regression tests: group-only search and vulnerability rows, owned
runners in scope, request count and concurrency of a large project
scope, and session pinning on an instance switch.

💡 Codex Review

const instanceUrl = normalizeInstanceUrl(getGitLabApiUrlFromContext() ?? GITLAB_BASE_URL);

P2 Badge Resolve profiles against the active static instance

After manage_context switch_instance in static-token mode, there is no OAuth context, so this fallback continues using the startup GITLAB_BASE_URL. Consequently, get_profile fetches /user from the previous instance and derives its profile ID and nickname from that old host even though other tools now target the selected instance; use the active instance source or current caller instead.

- A search of a group without its subgroups reads the group's own
  projects up to 1000; past them, rows of projects not read were
  dropped silently. The answer is now marked partial, with the reason
  added to any the page already had.
- The channel gateway tells the host to list tools again after it
  reconnects downstream: the new downstream may serve another catalog
  (settings changed during the outage, or the old link lost its
  notification).
- get_profile reads the account of the instance the server's token
  works with now, so it follows switch_instance like every other tool.

Regression tests: the truncated group search and combined partial
reasons, the catalog refresh after a reconnect, and the profile after
an instance switch.

- Scope paths are trimmed of their leading and trailing slashes in one
  pass; the end-anchored pattern backtracked over every run of slashes
  inside a path a caller supplies.
- The two-step settings check of a tool call (limits needing nothing
  from GitLab, then the scope with numeric targets resolved) is its own
  function instead of part of the call handler.
- list-tools counts a preset's tools from the same function that lists
  them, with the deny pattern built in one place, instead of two copies
  of the filtering.
- The search tool answers with its rows under `results`; the filter of
  a group search without subgroups expected a bare list and passed the
  answer through, so subgroup results stayed visible. The rows are now
  unwrapped, kept to the group and its direct projects, and returned in
  the search's own answer shape. The project search of a scope made of
  projects answers in that shape too.
- A project listing narrowed to the scope's group keeps the active
  projects default of a plain listing, unless the caller chose active
  or archived projects.
- The owned runners of a scope are marked partial when the target has
  more runners than are read.

Regression tests: the group search filtered through the real search
tool, search answer shapes, the active default and its overrides, and
the truncated runner intersection.
