mcp-gitlab

<!-- mcp-name: io.github.vish288/mcp-gitlab -->

mcp-gitlab is a Model Context Protocol (MCP) server for the GitLab REST API that provides 83 tools, 7 resources, and 6 prompts for AI assistants to manage projects, merge requests, pipelines, CI/CD variables, approvals, issues, code reviews, and more. Works with Claude Desktop, Claude Code, Cursor, Windsurf, VS Code Copilot, and any MCP-compatible client.

Supports GitLab.com and self-hosted GitLab instances (CE/EE). No GitLab Duo or Premium required.

Built with FastMCP, httpx, and Pydantic.

Install: uvx mcp-gitlab | PyPI | MCP Registry | Changelog

1-Click Installation

💡 Tip: For other AI assistants (Claude Code, Windsurf, IntelliJ, Gemini CLI), visit the GitLab MCP Installation Gateway.

triage_issues	project_id, label	List open issues → categorize → prioritize → identify duplicates

Usage Examples

Projects & Branches

"Get details for project my-org/api-gateway"
→ gitlab_get_project(project_id="my-org/api-gateway")

"Create a feature branch from main"
→ gitlab_create_branch(project_id="123", branch_name="feat/login", ref="main")

"Delete all branches merged into main"
→ gitlab_list_branches(project_id="123") → filter merged → gitlab_delete_branch for each

Merge Requests & Code Review

"Open a merge request from feat/login to main"
→ gitlab_create_mr(project_id="123", source_branch="feat/login", target_branch="main", title="Add login")

"Review MR !42 — list changes and add inline comments"
→ gitlab_mr_changes(project_id="123", mr_iid=42)
→ gitlab_create_mr_discussion(project_id="123", mr_iid=42, body="nit: ...", new_path="src/auth.py", new_line=15)

"Merge MR !42 after resolving all threads"
→ gitlab_list_mr_discussions(project_id="123", mr_iid=42) → resolve unresolved
→ gitlab_merge_mr(project_id="123", mr_iid=42, squash=True)

Pipelines & CI/CD

"Show failed pipelines on main this week"
→ gitlab_list_pipelines(project_id="123", ref="main", status="failed")

"Retry a failed pipeline"
→ gitlab_retry_pipeline(project_id="123", pipeline_id=456)

"Get the build log for job 789"
→ gitlab_get_job_log(project_id="123", job_id=789, tail_lines=100)

Issues

"Create a bug report in project 123"
→ gitlab_create_issue(project_id="123", title="Login page 500 error", labels=["bug","P1"])

"Find open issues assigned to me"
→ gitlab_list_issues(project_id="123", state="opened", assignee_username="johndoe")

Security Considerations

• Token scope: Use the minimum required scope. api scope grants full access; prefer read_api for read-only deployments.
• Read-only mode: Set GITLAB_READ_ONLY=true to disable all write operations (create, update, delete, merge). Read-only mode is enforced server-side before any API call.
• SSL verification: GITLAB_SSL_VERIFY=true by default. Only disable for self-signed certificates in trusted networks.
• CI/CD variable masking: gitlab_list_variables and gitlab_list_group_variables automatically mask values of variables marked as masked in GitLab, returning ***MASKED*** instead of the actual value.
• MCP tool annotations: Each tool declares readOnlyHint, destructiveHint, and idempotentHint for client-side permission prompts.
• No credential storage: The server does not persist tokens. Credentials are read from environment variables at startup.

Rate Limits & Permissions

Rate Limits

GitLab enforces per-user rate limits (default: 2000 requests/minute for authenticated users). When rate-limited, tools return a 429 error with a hint to wait before retrying. Paginated endpoints default to 20 results per page; use per_page (max 100) to reduce the number of API calls.

Required Permissions

Operation	Minimum GitLab Role
Read projects, MRs, pipelines, issues	Reporter
Create branches, MRs, issues	Developer
Merge MRs, manage CI/CD variables	Maintainer
Delete projects, manage approval rules	Maintainer/Owner
Share projects/groups	Owner (or Admin)

CLI & Transport Options

# Default: stdio transport (for MCP clients)
uvx mcp-gitlab

# HTTP transport (SSE or streamable-http)
uvx mcp-gitlab --transport sse --host 127.0.0.1 --port 8000
uvx mcp-gitlab --transport streamable-http --port 9000

# CLI overrides for config
uvx mcp-gitlab --gitlab-url https://gitlab.example.com --gitlab-token glpat-xxx --read-only

The server loads .env files from the working directory automatically via python-dotenv.
