name gitlab-mcp-skill
description Use this skill when working with the GitLab MCP server tools for merge requests, issues, repositories, pipelines, work items, variables, dependency proxy, vulnerabilities, webhooks, search, CI catalog, and related GitLab workflows.

gitlab-mcp

GitLab MCP server providing 262 tools: 260 tools across 21 toolsets, plus execute_graphql and the always-available discover_tools meta-tool.

For exact generated parameter tables, see docs/tools/. Use this file for workflow shape and high-signal parameter hints.

Toolsets

Toolset Default Enable with
merge_requests (44 tools) yes -
issues (24 tools) yes -
repositories (7 tools) yes -
branches (15 tools) yes -
projects (11 tools) yes -
labels (5 tools) yes -
ci (4 tools) yes -
groups (1 tool) yes -
users (7 tools) yes -
pipelines (56 tools) no USE_PIPELINE=true or GITLAB_TOOLSETS=pipelines
milestones (17 tools) no USE_MILESTONE=true or GITLAB_TOOLSETS=milestones
wiki (10 tools) no USE_GITLAB_WIKI=true or GITLAB_TOOLSETS=wiki
releases (7 tools) no GITLAB_TOOLSETS=releases
tags (5 tools) no GITLAB_TOOLSETS=tags
workitems (18 tools) no GITLAB_TOOLSETS=workitems
webhooks (6 tools) no GITLAB_TOOLSETS=webhooks
search (3 tools) no GITLAB_TOOLSETS=search
variables (10 tools) no GITLAB_TOOLSETS=variables
dependency_proxy (4 tools) no GITLAB_TOOLSETS=dependency_proxy
vulnerabilities (4 tools) no GITLAB_TOOLSETS=vulnerabilities
orbit (4 tools) no GITLAB_TOOLSETS=orbit

Enable all: GITLAB_TOOLSETS=all. Use GITLAB_TOOLS to enable individual tools outside their toolset. discover_tools can list and activate opt-in categories for the current session. execute_graphql is not in a toolset; enable it explicitly with GITLAB_TOOLS=execute_graphql.

The per-toolset counts above sum to 262 because get_branch and list_branches are each listed in both merge_requests and branches; the unique tool count across all toolsets is 260.

Key Workflows

Code Review (see reference/code-review.md)

  1. list_merge_request_changed_files - get file paths only (no diffs)
  2. get_merge_request_file_diff - get diffs for 3-5 files per call (batch)
  3. create_merge_request_thread or create_draft_note - leave review comments
  4. bulk_publish_draft_notes - publish all drafts at once

MR Lifecycle (see reference/merge-requests.md)

create_merge_request -> review -> approve_merge_request -> merge_merge_request

Issue Management (see reference/issues.md)

create_issue -> create_issue_link -> create_issue_note -> update_issue

Use update_issue_description_patch for small edits to long issue descriptions instead of resending the full body.

Projects & Namespaces

  • get_project, list_projects, update_project - inspect or change project settings
  • list_project_members, list_group_members - search members by name or username within a project or group
  • list_namespaces, get_namespace, verify_namespace - find target namespaces before creating projects/groups
  • verify_namespace.parent_id scopes nested namespace checks
  • create_repository.namespace_id creates a project under a group namespace

Branches & Commits

  • create_branch, list_branches, get_branch, delete_branch
  • Protected branches: list_protected_branches, get_protected_branch, protect_branch, unprotect_branch, update_default_branch
  • Commits: list_commits, get_commit, get_commit_diff, get_file_blame, list_commit_statuses, create_commit_status

CI

  • Lint configs: validate_ci_lint, validate_project_ci_lint
  • Catalog: list_ci_catalog_resources, get_ci_catalog_resource
  • Pipelines/jobs/deployments: see reference/pipelines.md

Work Items (see reference/work-items.md)

list_work_items -> get_work_item -> update_work_item -> create_work_item_note

Variables & Dependency Proxy

Enable with GITLAB_TOOLSETS=variables or GITLAB_TOOLSETS=dependency_proxy.

  • Variables: project/group CRUD tools (list_*_variables, get_*_variable, create_*_variable, update_*_variable, delete_*_variable)
  • Dependency proxy: get_dependency_proxy_settings, update_dependency_proxy_settings, list_dependency_proxy_blobs, purge_dependency_proxy_cache

Webhooks & Search

  • Webhooks: see reference/webhooks.md
  • Code search: see reference/search.md

Vulnerability Triage (see reference/vulnerability-triage.md)

Enable with GITLAB_TOOLSETS=vulnerabilities (requires GitLab Ultimate).

list_project_vulnerabilities -> get_vulnerability -> dismiss_vulnerability or confirm_vulnerability

File Operations

  • Read: get_file_contents, get_repository_tree
  • Write: create_or_update_file (single file), push_files (multiple files in one commit)

Parameter Hints

  • project_id: numeric ID or URL-encoded path (group%2Fsubgroup%2Fproject)
  • namespace_id: numeric namespace ID for create_repository; use list_namespaces/verify_namespace first
  • parent_id: scope subgroup creation or verify_namespace for nested groups
  • MR lookup: provide mergeRequestIid OR branchName (not both)
  • list_issues: default scope = created by current user. Use scope: "all" for all issues
  • list_merge_requests: without project_id returns user's MRs across all projects
  • CI catalog resource lookup: provide exactly one of id or full_path
  • emoji reactions: merge request, issue, and work item reaction tools use GitLab emoji names like thumbsup, rocket, or eyes
  • work items: status and custom fields require GitLab Premium/Ultimate features
  • execute_graphql: escape double quotes in query strings

Destructive Tools (require caution)

delete_branch, delete_deployment, approve_deployment, delete_draft_note, delete_environment, erase_pipeline_job, delete_group_milestone, delete_group_variable, delete_group_wiki_page, delete_issue, delete_issue_emoji_reaction, delete_issue_link, delete_issue_note_emoji_reaction, delete_label, delete_merge_request_discussion_note, delete_merge_request_emoji_reaction, delete_merge_request_note, delete_merge_request_note_emoji_reaction, delete_milestone, delete_pipeline, delete_pipeline_schedule, delete_pipeline_schedule_variable, delete_pipeline_trigger, delete_project_variable, delete_release, delete_review_app_environments, delete_tag, delete_webhook, delete_wiki_page, delete_work_item_emoji_reaction, delete_work_item_note_emoji_reaction, merge_merge_request, protect_branch, purge_dependency_proxy_cache, push_files, unprotect_branch, update_default_branch

Advanced

  • Dynamic discovery: discover_tools lists and activates opt-in toolsets at runtime
  • GraphQL: execute_graphql for queries not covered by REST tools
  • Tool docs: docs/tools/ is generated from tools/registry.ts; prefer it for exact schemas
  • Remote MCP OAuth: when GITLAB_MCP_OAUTH=true, POST /register (DCR) is rate-limited per client IP (default 20/hour via MCP SDK; tune with OAUTH_REGISTER_RATE_LIMIT_PER_HOUR). Separate from MAX_REQUESTS_PER_MINUTE and GitLab API quotas — see environment-variables.md
  • Zoekt search: search_code, search_project_code, search_group_code (requires advanced search enabled)
  • Work Items: GraphQL-based alternative to issues (Premium/Ultimate features)
