Summary

  • add a lean core toolset as the only default toolset
  • make the previous broad default toolsets opt-in via GITLAB_TOOLSETS/discover_tools
  • update toolset docs and tests for overlapping toolsets

Default tools drop from 115 to 36, with approximate schema tokens down from 24.2k to 8.9k.

Tests

  • npm run build
  • node --import tsx/esm --test test/test-ci-lint.ts
  • node --import tsx/esm --test test/test-todos.ts
  • node --import tsx/esm --test test/test-toolset-filtering.ts
  • npm run test:mock

Note

Medium Risk
This is a behavior-breaking default for clients that assumed the old wide tool list without setting GITLAB_TOOLSETS; upgrades need the documented restore string or GITLAB_TOOLSETS=all to avoid missing tools.

Overview
Shrinks the default MCP tool surface by introducing a core toolset (35 tools) as the only always-on group when GITLAB_TOOLSETS is unset, plus discover_tools. The former broad defaults (merge requests, issues, repositories, branches, projects, labels, CI, groups, users) are opt-in again.

Registry changes mark those categories isDefault: false, define overlapping tools in both core and the full toolsets, and use TOOLSETS_BY_TOOL_NAME so enabling a full category still exposes tools that also appear in core. Filtering tests now derive counts from TOOLSET_DEFINITIONS and assert advanced tools (merge, drafts, push_files, etc.) stay out of the lean default.

Docs and operator UX add docs/tools/core.md, CLI flags --toolsets / --tools, env-var guidance for all and a pre-lean restore toolset list, opt-in notes on group pages, and updated skill/MkDocs index. Tests for CI lint and todos require explicit GITLAB_TOOLSETS=ci / issues.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added a lean Core toolset as the default, with commonly used GitLab tools.
    • Added CLI options for enabling toolsets or individual tools.
    • Advanced tool categories are now opt-in, with an option to restore the previous default set.
    • Unavailable tools can indicate how to enable their toolset when applicable.
  • Documentation

    • Expanded configuration, CLI, tool reference, and localized README documentation.
    • Added detailed Core tool documentation and guidance for enabling tool categories, including runtime discovery.

Walkthrough

Adds core as the default toolset and makes the previous default toolsets opt-in. Tool membership and unavailable-tool messages now account for tools shared across toolsets. Tests and documentation reflect the updated defaults and activation options.

Changes

Lean core toolset + opt-in restructure

Layer / File(s) Summary
Toolset definitions and membership resolution
tools/registry.ts
Adds core, changes the previous default toolsets to opt-in, maps each tool to all toolsets that contain it, and enables a tool when any mapped toolset is enabled.
Unavailable-tool guidance
index.ts, test/test-permission-mode.ts
Unavailable-tool errors identify an activation option when a tool belongs to a known toolset and is not denied by the configured pattern. Tests cover the guidance and its omission for denied tools.
Toolset filtering and test environments
test/test-toolset-filtering.ts, test/test-ci-lint.ts, test/test-ci-catalog.ts, test/test-create-repository.ts, test/test-download-attachment.ts, test/test-dynamic-project-scope.ts, test/test-list-group-members.ts, test/test-list-group-merge-requests.ts, test/test-merge-request-pipelines.ts, test/test-remote-downloads.ts, test/test-todos.ts, test/test-update-project.ts, test/test-upload-markdown.ts
Filtering tests derive expected counts from toolset definitions and check default exclusions and smallest-toolset lookup. Affected tests explicitly enable the required opt-in toolsets.
Tool documentation generation
scripts/generate-tool-docs.ts
Adds core group metadata and ordering, reports tool overlap in opt-in notes, and adds a value that restores the previous default toolset set.
Core tool reference
docs/tools/core.md, mkdocs.yml
Adds the core tool reference and its navigation entry.
Default and opt-in toolset documentation
docs/tools/index.md, docs/tools/*.md, docs/configuration/environment-variables.md, docs/getting-started/cli-arguments.md, docs/reference/cli-usage-design.md, README*.md, skills/gitlab-mcp/SKILL.md
Documents the core default, opt-in toolsets, individual-tool and runtime activation, CLI arguments, environment variables, and the previous default set.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 4d758

The new Core reference page should describe get_issue responses as issues, not milestones. The other remaining documentation concerns predate this change; they warrant follow-up but do not block this merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 4d758

The smaller default surface does not add newly exposed capabilities, and runtime activation preserves the examined permission and denial controls. However, stateless deployments cannot retain runtime activation between requests, so tools removed from the defaults require explicit startup configuration.

Retained concerns

  • Medium · architecture · inferred: Stateless HTTP cannot retain discover_tools activation for subsequent requests. The handler reports activation after modifying server-local filteredTools, but the next request creates a fresh server and rejects newly omitted tools again. This lifecycle limitation predates the PR, but moving formerly default tools to opt-in expands its impact and makes runtime activation an ineffective recovery path for those deployments. Explicit startup tool or category selection is the bounded workaround; enabling every category is unnecessary and abandons the intended lean exposure.
Security review details

Security Blast Radius

  • inferred — A caller can expand its server instance's exposed category set through discovery, but the inspected activation block does not change credentials, API URL, or project allowlist. Subsequent handlers inherit the existing request-local identity and scope. Potential GitLab impact therefore depends on existing credential authority and handler controls, not the size of core; all downstream handlers were not independently audited.

Trust Boundaries and Controls

  • observed — The examined client-controlled category path passes category validation and per-tool permission, deny-regex, and hidden filters before activation. Direct invocation also checks current exposure, subject to the documented hidden exemption, and ordinary dispatch retains centralized permission enforcement. Core overlap changes eligibility but does not bypass those checks.

Hardening Proposals

  • proposed — For stateless deployments, distinguish request-local activation from persistent configuration in the activation response and guidance. Prefer explicit required categories or individual tools as the recovery path rather than enabling all categories.

prepend it with GITLAB_TOOLSETS= so it reads

In `@tools/registry.ts`:
- Around line 1869-1875: The map TOOLSET_BY_TOOL_NAME declared alongside

Remove the unused TOOLSET_BY_TOOL_NAME map declaration and any code that
populates it within the loop that iterates over TOOLSET_DEFINITIONS. Ensure that
only TOOLSETS_BY_TOOL_NAME remains, which correctly maintains the set of
toolsets for each tool name.

The core toolset documentation is comprehensive and well-structured. The tool list is complete with 35 tools correctly categorized (merge requests, issues, repositories, branches, projects, labels, identity), and the detailed documentation with parameter tables follows consistent formatting.

mkdocs.yml (1)

87-87: LGTM!

The nav entry correctly registers the new core toolset documentation in the sidebar.

docs/tools/index.md (5)

19-20: LGTM!

Default/opt-in structure is clear and correct. Default is exclusively Core, and the opt-in list comprehensively covers all 19 other toolsets.


26-26: LGTM!

The restore value GITLAB_TOOLSETS=merge_requests,issues,repositories,branches,projects,labels,ci,groups,users correctly documents the pre-lean default set and matches the value in the doc generator (scripts/generate-tool-docs.ts:315).


46-93: LGTM!

Core section is prominent and accurate: title, description, "(35 tools)" count, and full tool table all align with core.md inventory. The core tools table rows match the 35 tools listed in core.md (lines 7-41) with no discrepancies.


92-92: LGTM!

All opt-in notes follow the standard format from generate-tool-docs.ts and correctly specify the toolset ID and activation methods (GITLAB_TOOLSETS, GITLAB_TOOLS, discover_tools).

Also applies to: 111-111, 127-127, 151-151, 161-161, 213-213, 246-246, 287-287, 395-395

The discover_tools available categories list includes core and all 19 other toolsets (20 total), accurately reflecting the new toolset inventory.

docs/getting-started/cli-arguments.md (1)

35-36: LGTM!

The two new CLI argument rows correctly document the toolsets and tools options, with clear descriptions of default behavior (lean core) and additive tool selection. These map to GITLAB_TOOLSETS_RAW and GITLAB_TOOLS_RAW in config.ts.

README.md (1)

96-97: LGTM!

The CLI argument documentation is consistent with docs/getting-started/cli-arguments.md and correctly specifies the lean core default and additive tool selection. The descriptions are appropriately verbose for a README audience.

skills/gitlab-mcp/SKILL.md (1)

8-35: LGTM!

The toolsets table and introduction accurately reflect the new default/opt-in structure. Core is correctly marked as default with 35 tools, all 19 other toolsets are marked opt-in with their tool counts, and the restore instruction on line 35 matches the index.md value exactly. The 204 total / 202 unique count is consistent with multi-toolset tool membership.

리뷰만 요청해서 코드는 안 건드렸다. 필터링 로직이랑 테스트는 직접 돌려보고, CodeRabbit 코멘트는 현재 HEAD 기준으로 다시 검증했다.

결론

방향은 맞다. 기본값 축소 + overlapping membership은 의도대로 동작한다. GITLAB_TOOLSETS가 비면 core만 켜지고, merge_requests만 켜도 list_merge_requests 같은 겹치는 툴은 살아있다. 기본 36개(core 35 + discover_tools) 주장도 레지스트리랑 맞는다.

머지를 막을 기능 버그는 못 찾았다. 문제는 브레이킹 체인지 안내랑 에이전트 스킬이 기본값 현실과 안 맞는 쪽이다.

PR: #547

CodeRabbit — 지금 코드 기준으로 다시 봄

지적 판정 이유
env restore에 GITLAB_TOOLSETS= 빠짐 이미 해결 environment-variables.md 452줄에 prefix 있음
NON_DEFAULT_TOOLSETS unused 이미 해결 테스트 파일에서 제거됨
Core를 36개로 고쳐라 틀린 지적 Core 그룹은 35개. 36은 discover_tools 포함 기본 노출 수
스킬 인트로 202/239 이미 해결 지금 258 tools: 256 across 21 toolsets. npm run check:skill-sync 통과
TOOLSET_BY_TOOL_NAME 잔존 유효, 마이너 write-only. last-write-wins라 whoami가 users로 덮인다. 지금 읽는 곳 없음
Meta & GraphQL을 opt-in 행렬에 넣음 문서 이슈, 기능 아님 meta는 toolset이 아님. 페이지 본문 노트는 맞는데 index 표가 헷갈림

내가 추가로 본 것

Warning — CHANGELOG에 이 브레이킹이 없다. CHANGELOG.md Unreleased Breaking changes에 update_issue slim response, Node 18.17만 있고, 기본 툴 115→36 축소는 없다. 업그레이드하는 사람 입장에선 README/스킬보다 여기를 먼저 본다.

Warning — 스킬 Key Workflows가 기본값에 없는 툴을 전제로 한다. create_draft_note, approve_merge_request, merge_merge_request는 merge_requests opt-in이다. 기본 설치 에이전트가 스킬 따라가면 툴 없음으로 터진다. 이 PR이 스킬 테이블은 고쳤는데 워크플로 문구는 안 고쳤다.

Warning — README에 restore 문자열이 없다. --toolsets=all / lean core만 있고, 구기본값 복구 예시는 env/tools index/스킬에만 있다. 첫 진입점이 README면 업그레이드 경로가 안 보인다.

Note — overlapping membership 단위 테스트가 없다. parseEnabledToolsets / isToolInEnabledToolset을 직접 치는 테스트가 없다. 서버 띄우는 통합 테스트(defaults include core samples)가 간접 커버하긴 한다. 회귀 방지로는 얇은 유닛이 더 싸다.

Note — GITLAB_TOOLSETS=issues는 core를 대체하지 추가가 아니다. 기존 의미라 버그는 아닌데, lean default 이후로는 GITLAB_TOOLSETS=ci 한 줄이 MR/이슈 툴을 전부 날린다. 문서에 “replaces the default set”를 더 세게 써야 한다.

테스트

직접 돌림.

  • node --import tsx/esm --test test/test-toolset-filtering.ts test/test-ci-lint.ts test/test-todos.ts → 47/47 pass
  • npm run check:skill-sync → pass
  • npm run lint → 이 브랜치 문제가 아님. ESLint 9가 .eslintrc.json을 못 읽는다. 원래 깨져 있음

보안 쪽으로는 기본 표면 축소가 맞다. destructive(merge_merge_request, push_files, delete_issue)는 기본에서 빠졌고, create/update류는 core에 남은 게 의도된 starter set로 보인다.


진짜야? 제대로 한거 맞아? 레지스트리 숫자, overlap 멤버십, 테스트 47개는 로컬에서 다시 확인했다. CodeRabbit 35→36이랑 202→239는 현재 HEAD에선 틀린/철 지난 지적이다.

자신감 8/10. 필터링 동작은 확신한다. CHANGELOG/README/스킬 워크플로는 문서 공백이라 머지 후에 운영 이슈로 터질 여지는 있다. 원하면 그 세 개만 최소 패치 넣겠다.

114-114: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the get_issue response description.

This text says that get_issue returns a slim milestone and a complete milestone object. The tool returns an issue. Describe the default as a slim issue and full_response=true as the complete issue object.

Regenerate the tool-count summaries in all README files.

The current skill inventory documents 256 unique toolset tools plus execute_graphql and discover_tools (258 total). Update every README summary and the generated tool list so all languages describe the same inventory.

  • README.md#L25-L25: replace the stale 232 tools + discover_tools summary.
  • README.md#L38-L38: replace the stale ~232 granular tools comparison value.
  • README.ko.md#L20-L20: update the Korean tool count.
  • README.zh-CN.md#L20-L20: update the Chinese tool count.

Mark execute_graphql as write-capable.

Line 19 states that callers can send GraphQL mutations, but the tool index and heading still label execute_graphql as read-only. This can cause clients or users to skip write confirmation for a state-changing operation. Update the labels to indicate mixed read/write behavior.

In `@docs/tools/branches.md`:
- Around line 5-6: Update the feature-toggle notes for the branches
documentation around the get_branch and list_branches tool entries to
distinguish those core-overlapping tools from the opt-in tools. Also update
docs/tools/issues.md lines 5-6 to identify the core issue tools and state that
only the remaining Issues tools require GITLAB_TOOLSETS=issues.

In `@docs/tools/core.md`:
- Line 85: The merge-request descriptions use parameter names that differ from
the tool schema. Update the authoritative descriptions for all affected entries
to use merge_request_iid and source_branch, then regenerate the documentation
page so its prose matches the schema.
- Line 326: Update the get_issue tool description so it refers to a slim issue
and complete issue object, with full_response controlling the complete issue
response; preserve the remaining guidance, then regenerate the affected
documentation page.

23-23: Keep Meta & GraphQL out of the opt-in toolset list.

discover_tools is always exposed, and execute_graphql is not part of a toolset. Listing this mixed-availability group as opt-in conflicts with the note below.
