Summary

Duo settings (#607)

  • manage_project update accepts auto_duo_code_review_enabled, duo_remote_flows_enabled, duo_sast_fp_detection_enabled, duo_sast_vr_workflow_enabled, duo_secret_detection_fp_enabled, duo_dependency_bump_breaking_changes_enabled; manage_namespace update accepts auto_duo_code_review_enabled. Each parameter is gated by the GitLab version that introduced it (18.0 to 19.2).
  • GitLab silently drops attributes gated by license, add-on or feature flag and still answers 200. Project/group updates now compare the returned entity and list such settings in not_applied (setting, requested, current, requires).

Version support policy

  • GitLab 16.0 is the oldest supported release (MIN_SUPPORTED_VERSION). minVersion values at or below it are removed; the remaining ones are checked against GitLab release sources (REST docs history, Grape params, GraphQL reference at release tags) and corrected where they were wrong.
  • Requirements declared for a single action are enforced: an action the instance cannot serve is removed from the tool schema, a tool left with no actions is hidden, and a call to such an action is refused with the unmet requirement instead of reaching GitLab.
  • Group webhooks (Premium) are refused on GitLab Free with a clear reason; project webhooks stay available and refuse the group-only project_events / subgroup_events.
  • Restore of projects and groups on GitLab Free requires 18.0 (the 17.11 routes answer 404 unless a disabled-by-default development flag is on).
  • AGENTS.md documents the policy and the "smart MCP, not an API proxy" rule for contributors and reviewers.

Schema-adaptive GraphQL

  • The GraphQL client adapts each document to the connected instance schema (from introspection): fields marked with the client-side @optional directive are dropped when missing, inline fragments on unknown types are removed, and variables that become unused are not declared or sent. A kept field whose sub-selections were all dropped becomes { __typename }. Essential fields are kept so GitLab reports them.
  • Pooled per-instance clients (multi-instance mode) read the same instance schema.

Emulation instead of gating on older instances

  • Access tokens: before 17.2 the state filter is applied client-side before pagination, walking GitLab's pages until the requested filtered page is complete.
  • Users: humans / exclude_active / exclude_humans emulated before 17.3, applied before pagination over at most 2000 users per call (a warning says when later matches may be missing). Without the bot flag (non-admin tokens) humans can only exclude project bots and the result carries a warning (_warning, or searchMetadata.warning for smart search); exclude_humans refuses with a clear reason. Smart search reports failures instead of an empty result and drops the active/humans defaults when the matching exclusion is requested.
  • Commit diffs: unidiff headers built client-side before 16.5.
  • Runners: list_owned falls back to REST when CurrentUser.runners is missing, matching search before pagination.
  • Container registry: newer fields are optional, so actions no longer need a version gate.
  • Work items: list/get fall back to project/group queries; create applies widgets the create input lacks through one follow-up update (reported in _warning.failedProperties if it fails); create and update name a widget the instance cannot set at all, before writing anything, instead of failing on schema validation.

Release workflow

  • A release publishes one GitHub release: the version-locked db package's duplicate release is deleted right after creation (its tag stays, release-please uses it to find the previous db release) and the core release is marked latest. npm, Docker and MCPB publishing for both packages is unchanged.

Testing

  • Lint (typecheck + eslint), unit tests and the integration suite against a live GitLab Ultimate instance. The only integration failure is the webhook creation test hitting a 10 s headers timeout on the test instance; it passes with a longer timeout.

BREAKING CHANGE: GitLab releases older than 16.0 are no longer supported; tools are hidden on such instances.

Closes #607

- manage_project update: auto_duo_code_review_enabled, duo_remote_flows_enabled,
  duo_sast_fp_detection_enabled, duo_sast_vr_workflow_enabled,
  duo_secret_detection_fp_enabled, duo_dependency_bump_breaking_changes_enabled;
  manage_namespace update: auto_duo_code_review_enabled. Each is gated by the
  GitLab version that introduced it
- Project/group updates report settings GitLab silently ignored (license,
  add-on or feature flag) in not_applied, instead of implying success
- Declare GitLab 16.0 as the oldest supported release; drop minVersion values
  at or below it and verify the remaining ones against GitLab release sources
- Adapt GraphQL documents to the connected instance schema: fields marked
  @optional and fragments on unknown types are pruned, unused variables dropped
- Emulate newer API behaviour on older instances instead of hiding it:
  client-side token state filter, user type filters, unified diff headers,
  REST fallback for owned runners, project/group fallbacks for work item
  list/get, deferred update for widgets the create input lacks
- Add AGENTS.md with the version support policy for contributors and reviewers

BREAKING CHANGE: GitLab releases older than 16.0 are no longer supported; tools are hidden on such instances.

📝 Walkthrough

Walkthrough

The changes establish GitLab 16.0 as the supported floor. They add version- and schema-aware REST and GraphQL fallbacks, work-item compatibility paths, Duo setting reporting, action availability filtering, and release workflow updates.

Changes

GitLab compatibility and adaptive tooling

Layer / File(s) Summary
Supported version floor and requirements
AGENTS.md, packages/gitlab-mcp/src/services/InstanceCapabilities.ts, packages/gitlab-mcp/src/services/WidgetAvailability.ts, packages/gitlab-mcp/src/entities/*/registry.ts, packages/gitlab-mcp/docs/*
Tool availability now uses GitLab 16.0 as the baseline. Higher minimum versions remain on selected actions and parameters.
Schema-indexed GraphQL adaptation
packages/gitlab-mcp/src/services/SchemaIntrospector.ts, packages/gitlab-mcp/src/services/ConnectionManager.ts, packages/gitlab-mcp/src/graphql/*
Schema introspection indexes fields and arguments. GraphQL requests remove unsupported optional selections and unused variables.
Version-aware handlers and work-item fallbacks
packages/gitlab-mcp/src/entities/access_tokens/registry.ts, packages/gitlab-mcp/src/entities/core/registry.ts, packages/gitlab-mcp/src/entities/runners/registry.ts, packages/gitlab-mcp/src/utils/smart-user-search.ts, packages/gitlab-mcp/src/entities/workitems/registry.ts
Handlers emulate unsupported filters, format older diff responses, use REST runner fallback, and select project or group work-item queries when namespace fields are unavailable.
Duo settings and action availability
packages/gitlab-mcp/src/entities/core/duo-settings.ts, packages/gitlab-mcp/src/entities/core/schema.ts, packages/gitlab-mcp/src/registry-manager.ts, packages/gitlab-mcp/src/utils/schema-utils.ts
Project and group updates accept Duo settings and report values GitLab did not apply. Unavailable actions are removed from advertised schemas and refused before handler execution.

Release workflow

Layer / File(s) Summary
Release cleanup and output handling
.github/workflows/release-please.yml
The workflow removes duplicate database releases, marks applicable core releases as latest, quotes publisher paths, and writes job summaries through one redirected block.

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

Merge Risk: 🟡 Moderate · up to 32041

On GitLab 18.5-18.7, listing a group's projects by active state can return projects outside the requested state. Pre-17.3 user searches can report "no users found" without saying that an earlier search stopped at its scan limit. Project webhooks accept a group-only event field. The project-listing version gate should be fixed before merge; the other issues are smaller follow-ups.

The version-locked db package got its own GitHub release that only repeated
the core one: the core release already carries both MCPB bundles. Delete the
db release object right after release-please creates it and mark the core
release as latest. The db tag stays, since release-please finds the previous
db release by it.

Also quote the summary and mcp-publisher paths flagged by shellcheck.

Inline comments:
In `@packages/gitlab-mcp/docs/advanced/context-switching.md`:
- Around line 123-131: Update the work-item version table in the
context-switching documentation to reflect schema-aware fallbacks: preserve the
18.1+ namespace-listing distinction, indicate project/group listing fallbacks
and get/create/update/delete support on older versions, and show that
link/unlink requires GitLab 16.4.

In `@packages/gitlab-mcp/src/entities/core/registry.ts`:
- Around line 887-890: Update both project and group restore handlers to require
GitLab 18.0 for Free-tier instances instead of 17.11, and revise their schema
descriptions to reflect the same minimum version. Locate the handlers by the
`assertInstanceAtLeast` check and the associated restore schema descriptions.

In `@packages/gitlab-mcp/src/entities/runners/registry.ts`:
- Around line 122-131: Validate the external response in the runners handler by
parsing the result of gitlab.get with z.array(RestRunnerSchema) before mapping,
and derive the RestRunner type from that schema instead of maintaining a
separate interface. Ensure the schema validates runner_type and the other fields
used by the mapping.

In `@packages/gitlab-mcp/src/services/ConnectionManager.ts`:
- Around line 263-264: Configure each pooled base client returned by
getInstanceClient with its instance’s SchemaIntrospector field-index provider,
replacing the default provider that returns undefined. Ensure authenticated
proxy clients delegate to the configured base client so GraphQLClient.request
can prune schema-dependent fields.

In `@packages/gitlab-mcp/src/utils/smart-user-search.ts`:
- Around line 131-132: Replace the `Array.isArray(body)` fallback and
`ListedUser[]` cast in the user response parsing with a Zod array schema that
validates each user’s optional `state` and `bot` fields; let parsing fail for
non-array or invalid responses instead of treating them as an empty user list.

In
`@packages/gitlab-mcp/tests/integration/schemas-dependent/duo-settings.test.ts`:
- Around line 78-90: Restore the shared fixture’s Duo settings after each test:
in the project test, wrap the update and assertions following `before` and
`requested` in a `try/finally`, then use `manage_project` to restore each
offered setting from `before` in the `finally` block. Apply the same pattern to
the group test, using `manage_namespace`.

When all sub-selections of a kept field, or of the whole operation, were
@optional fields missing from the instance schema, the original selection was
sent unchanged: the client-only @optional directive and the missing fields
reached GitLab, which rejected the query. Such a selection now becomes
{ __typename }, valid on every type.
The map naming the tool parameter behind each update widget is now keyed by
the widget fields of WorkItemUpdateInput, so a new widget without a name fails
to compile instead of reaching users as a raw widget key. Adds tests for the
remaining project/group fallbacks and for deferring the description on create.
Requirements declared for a single action were never applied: the registry
checked only the tool default, so an action the instance cannot serve stayed
in the schema and its call reached GitLab. The registry now removes such
actions from the tool schema, hides a tool left with none, and refuses a call
to one with the unmet requirement as the reason. Covered by a registry test
that failed before the change.

The version compatibility table in the docs now describes the work item
fallbacks instead of claiming older instances lose most actions.
On Free 17.11 the restore routes answer 404 unless a disabled-by-default
development flag is enabled; 18.0 made delayed deletion unconditional. Restore
on Free now requires 18.0, and the action descriptions say so.
A malformed entry in the REST fallback of list_owned crashed the mapping with
a TypeError. The response is now validated and a mismatch is reported as an
unexpected GitLab response.
Clients from the multi-instance connection pool had no schema source, so
their documents were sent without being adapted to older instances.
getInstanceClient now gives them a per-instance provider that reads the
instance's introspected schema on each request.
- Smart user search no longer turns a failed GitLab call, including the
  refusal to filter bot users on older instances, into an empty result.
- The active/humans defaults are dropped when the caller asks to exclude
  active users or humans; together they could only ever return nothing.
- A /users body that is not a user list is reported as an unexpected
  response instead of being read as no users.
GitLab silently ignores these on older instances while reporting success.
Webhook name and description arrived in 17.1 (the descriptions wrongly said
16.11) and CI/CD variable description in 16.2; each is now gated at that
version.
Before 17.2 the state filter was applied to a single unfiltered page, so a
match on a later page was lost. GitLab's pages are now walked until the
requested filtered page is complete or the list ends.

…16.0

GET job_token_scope predates 16.0, but the whole browse tool was gated at
16.1, hiding it there. The tool now defaults to the supported floor and gates
list_projects at 16.1 and list_groups at 16.10, the releases that added their
allowlist endpoints.
The REST fallback matched `search` within one unfiltered page, so a match on
a later page was lost and a page could come back empty. With a search, REST
pages are now walked until the requested page of matches is complete, and the
cursor counts pages of matches.
On GitLab before 17.3 the emulated user-type filters ran on one unfiltered
page, so matches on later pages were lost; GitLab's pages are now walked until
the requested filtered page is complete. Without the bot flag (non-admin
tokens) humans can only exclude project bots, so such a result now carries a
warning: `_warning` next to the list for a plain search, and
`searchMetadata.warning` for smart search.
A widget missing from both the create and the update input was deferred to
the follow-up update, where GitLab rejected the whole mutation and so dropped
the supported deferred widgets too. Such a widget is now refused before
anything is created, with the same check update already used.

🟡 Minor · Gate group webhooks in the handler. · registry.ts:88-90

packages/gitlab-mcp/src/entities/webhooks/registry.ts:88-90
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Gate group webhooks in the handler.

ManageWebhookSchema accepts create, update, delete, and test. resolveRequirement performs an exact lookup by the submitted action. The handler passes only input.action to assertActionAllowed; it does not derive a key from scope. Therefore, create_group, update_group, and delete_group never gate a call.

Reject scope === 'group' below Premium before getBasePath, then remove the unused requirement keys.

Suggested fix
         actions: {
-          create_group: { tier: 'premium', notes: 'Group webhooks' },
-          update_group: { tier: 'premium', notes: 'Group webhooks' },
-          delete_group: { tier: 'premium', notes: 'Group webhooks' },
           // Project hook test endpoint; the group one (17.1) is checked in the handler.
           test: { tier: 'free', minVersion: '16.11' },
         },

Add a handler check before getBasePath that rejects group scope below Premium with Group webhooks require GitLab Premium.

The same keys were present in the base revision, so their mismatch predates this PR.

- Emulated unidiff headers were built from an unchecked body, so a diff
  missing its paths produced "a/undefined" headers; the diff list is now
  validated and a mismatch is reported as an unexpected response.
- Token pages filtered client-side before 17.2 are validated the same way,
  since a token without `active` would silently fail the filter.
On GitLab before 17.3 a filter matching few users could walk every /users
page of a large instance in one call. The walk now stops after 20 pages
(2000 users) and the result says later matches may be missing, alongside any
partial-humans warning.
Group webhooks are a Premium feature, but the requirement was declared on
create_group/update_group/delete_group, which are not actions of the tool, so
it never applied. Both webhook tools now refuse the group scope on Free with a
clear reason before calling GitLab; the unused requirement keys are removed.
Writing Duo settings on the shared test project and group turned inherited
values into explicit overrides for later tests, even when restored. The tests
now create their own subgroup and project and delete them afterwards.

🟠 Major · Use a separate version gate for group project listings. · registry.ts:209

packages/gitlab-mcp/src/entities/core/registry.ts:209
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Use a separate version gate for group project listings.

On GitLab 18.5-18.7, activeFilterSupported makes the group-list branch send active and delete archived. GitLab introduced active for GET /groups/:id/projects in 18.8. A group listing can therefore return projects outside the requested active state. Gate the group endpoint at 18.8; keep the global project-list gate separate. (docs.gitlab.com)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Restrict project_events to group-scope webhooks.

CreateWebhookSchema and UpdateWebhookSchema accept project_events with either scope. buildRequestBody then forwards it to the project endpoint. Add a scope-specific schema restriction so project-scope requests reject this field.

GET /groups/:id/projects gained `active` in 18.8, three releases after
GET /projects. On 18.5-18.7 the group listing sent `active`, which GitLab
ignored, returning projects outside the requested state. The group branch now
translates to `archived` below 18.8; the global listing keeps its 18.5 gate.
project_events and subgroup_events exist only on the group hooks API; sent to
a project hook they were silently ignored while the call reported success.
They are now refused for project scope with a clear reason.
Smart search reported only the warning of its last phase, so a first phase
that scanned just part of the instance vanished behind an empty
transliteration phase. Warnings of all phases run are now kept.
