Setup Overview

Authentication Methods

The server supports four authentication methods:

For local/desktop use (most common):

1. Personal Access Token (GITLAB_PERSONAL_ACCESS_TOKEN) — simplest setup
2. OAuth2 — Local Browser (GITLAB_USE_OAUTH) — recommended for better security

For server/remote deployments:

3. OAuth2 — MCP Proxy (GITLAB_MCP_OAUTH) — for remote MCP clients such as Claude.ai
4. Remote Authorization (REMOTE_AUTHORIZATION) — multi-user deployments where each caller provides their own token

Quick setup paths

• Codex: see Codex Setup Guide
• Cursor: see Cursor Setup Guide
• Factory AI Droid / OpenClaw / OpenCode style clients: see JSON-Based MCP Clients Setup Guide
• OAuth browser flow details: see OAuth2 Authentication Setup Guide

For the simplest local setup, start with a Personal Access Token. For browser-based local auth, use OAuth2. For remote or multi-user deployments, continue to the MCP OAuth and Remote Authorization sections later in this README.

Using CLI Arguments (for clients with env var issues)

Some MCP clients (like GitHub Copilot CLI) have issues with environment variables. Use CLI arguments instead:

{
  "mcpServers": {
    "gitlab": {
      "command": "npx",
      "args": [
        "-y",
        "@zereight/mcp-gitlab",
        "--token=YOUR_GITLAB_TOKEN",
        "--api-url=https://gitlab.com/api/v4"
      ],
      "tools": ["*"]
    }
  }
}

Available CLI arguments:

• --token - GitLab Personal Access Token (replaces GITLAB_PERSONAL_ACCESS_TOKEN)
• --api-url - GitLab API URL (replaces GITLAB_API_URL)
• --read-only=true - Enable read-only mode (replaces GITLAB_READ_ONLY_MODE)
• --use-wiki=true - Enable wiki API (replaces USE_GITLAB_WIKI)
• --use-milestone=true - Enable milestone API (replaces USE_MILESTONE)
• --use-pipeline=true - Enable pipeline API (replaces USE_PIPELINE)

CLI arguments take precedence over environment variables.

Using MCP OAuth Proxy (GITLAB_MCP_OAUTH)

For server/remote deployments only. This mode requires the MCP server to be deployed with a publicly accessible HTTPS URL. For local/desktop use, see GITLAB_USE_OAUTH above.

For remote MCP clients that support the MCP OAuth specification (e.g. Claude.ai). The server acts as a full OAuth 2.0 authorization server — unauthenticated requests receive a 401 + WWW-Authenticate response, which triggers the OAuth browser flow automatically on the client side.

Remote MCP clients such as OpenCode, MCPJam, and Claude.ai can send their own callback URL during authorization. If you cannot register every client callback URL in GitLab, enable GITLAB_OAUTH_CALLBACK_PROXY=true. With callback proxy mode, GitLab only needs one registered redirect URI: {MCP_SERVER_URL}/callback.

GITLAB_OAUTH_REDIRECT_URI is for local OAuth (GITLAB_USE_OAUTH) only. It does not override remote MCP OAuth client callback URLs and should not be used to fix remote Unregistered redirect_uri errors.

This variable exists because the local OAuth flow starts a browser on the same machine as the MCP server and listens for the callback on a local HTTP server, for example http://127.0.0.1:8888/callback.

Remote MCP OAuth is different. In GITLAB_MCP_OAUTH=true mode, the MCP client provides its own callback URL during /authorize. GITLAB_OAUTH_REDIRECT_URI does not replace that client-provided URL.

Mode	Enable with	Callback variable	GitLab redirect URI
Local OAuth	GITLAB_USE_OAUTH=true	GITLAB_OAUTH_REDIRECT_URI	http://127.0.0.1:8888/callback or your local callback
Remote MCP OAuth	GITLAB_MCP_OAUTH=true	GITLAB_OAUTH_CALLBACK_PROXY=true	{MCP_SERVER_URL}/callback

Use GITLAB_OAUTH_REDIRECT_URI only when the MCP server itself owns the local browser callback. Use GITLAB_OAUTH_CALLBACK_PROXY=true when a remote MCP client owns the callback URL.

How it works: You deploy this MCP server somewhere with a public HTTPS URL. MCP clients connect to {MCP_SERVER_URL}/mcp. The server handles the OAuth 2.0 flow, exchanging credentials with GitLab on behalf of the client.

Prerequisites:

1. A publicly accessible HTTPS server URL (MCP_SERVER_URL) — use ngrok for local testing
2. A pre-registered GitLab OAuth application with api (or read_api) scopes — Go to Admin area → Applications, set Redirect URI to {MCP_SERVER_URL}/callback

Environment Variable	Required	Description
GITLAB_MCP_OAUTH	✅	Set to true to enable
GITLAB_API_URL	✅	GitLab API base URL
GITLAB_OAUTH_APP_ID	✅	GitLab OAuth Application ID
MCP_SERVER_URL	✅	Public HTTPS URL of this MCP server
STREAMABLE_HTTP	✅	Must be true
GITLAB_OAUTH_CALLBACK_PROXY	optional	Set to true to use the MCP server's fixed /callback URL
GITLAB_OAUTH_SCOPES	optional	Comma-separated scopes (default: api,read_api,read_user)
GITLAB_OAUTH_ALLOWED_GROUPS	optional	Comma-separated group full paths — only members (and subgroup members) may obtain a token (replaces deprecated GITLAB_ALLOWED_GROUPS)

When STREAMABLE_HTTP=true, server-side GITLAB_PERSONAL_ACCESS_TOKEN or GITLAB_JOB_TOKEN require REMOTE_AUTHORIZATION=true or GITLAB_MCP_OAUTH=true.

Troubleshooting Unregistered redirect_uri

Check the redirect_uri in the browser URL. If it points to a client callback such as http://127.0.0.1:xxxxx/.../callback, enable:

GITLAB_OAUTH_CALLBACK_PROXY=true

Do not fix remote MCP OAuth by changing GITLAB_OAUTH_REDIRECT_URI. That variable is for local OAuth (GITLAB_USE_OAUTH) only.

docker run -i --rm \
  -e HOST=0.0.0.0 \
  -e GITLAB_MCP_OAUTH=true \
  -e GITLAB_OAUTH_CALLBACK_PROXY=true \
  -e STREAMABLE_HTTP=true \
  -e MCP_SERVER_URL=https://your-server.example.com \
  -e GITLAB_API_URL="https://gitlab.com/api/v4" \
  -e GITLAB_OAUTH_APP_ID=your_app_id \
  -p 3000:3002 \
  zereight050/gitlab-mcp

MCP client configuration:

{
  "mcpServers": {
    "gitlab": {
      "type": "http",
      "url": "https://your-server.example.com/mcp"
    }
  }
}

Using Remote Authorization (REMOTE_AUTHORIZATION)

For server/remote deployments only. Each HTTP caller provides their own GitLab token directly in request headers — no OAuth flow involved.

For multi-user or multi-tenant deployments where each caller provides their own GitLab token in the HTTP request header. No OAuth flow — the MCP server forwards the token to GitLab on behalf of the caller.

Header priority: Private-Token > JOB-TOKEN > Authorization: Bearer

Environment Variable	Required	Description
REMOTE_AUTHORIZATION	✅	Set to true to enable
STREAMABLE_HTTP	✅	Must be true
ENABLE_DYNAMIC_API_URL	optional	Allow per-request GitLab URL via X-GitLab-API-URL header
GITLAB_ALLOW_UNAUTHENTICATED_TOOL_DISCOVERY	optional	Allow unauthenticated initialize, notifications/initialized, and tools/list only (tool calls still require auth)
MCP_TRUST_PROXY	optional	Trust Forwarded / X-Forwarded-* headers behind a reverse proxy (download URLs, Express req.ip, OAuth rate limits)

GITLAB_ALLOW_UNAUTHENTICATED_TOOL_DISCOVERY=true is intended for MCP gateways or admin UIs that need to inspect tool metadata before a user provides a GitLab token. Leave it disabled unless the tool list is safe to expose in your deployment.

When MCP_SERVER_URL is not set, remote download URLs fall back to the local server address. Set MCP_TRUST_PROXY=true only if the server is reachable through a trusted reverse proxy and direct client access to the MCP server is blocked. This enables Express trust proxy for Streamable HTTP and SSE, derives public download URLs from Forwarded / X-Forwarded-Proto / X-Forwarded-Host / X-Forwarded-Prefix, and keeps OAuth endpoint rate limiting working when proxies send X-Forwarded-For with a client port (for example 1.2.3.4:5678). Existing OAuth+proxy deployments must set this explicitly after the flag was introduced.

Example request headers:

Private-Token: glpat-xxxxxxxxxxxxxxxxxxxx

or using a Bearer token:

Authorization: Bearer glpat-xxxxxxxxxxxxxxxxxxxx

⚠️ REMOTE_AUTHORIZATION is not compatible with SSE transport. STREAMABLE_HTTP=true is required.

Environment Variables

Use the dedicated reference for the full environment variable list:

• Environment Variables Reference

Most users only need one of these starting sets:

• Local PAT: GITLAB_PERSONAL_ACCESS_TOKEN, GITLAB_API_URL
• Local OAuth: GITLAB_USE_OAUTH=true, GITLAB_OAUTH_CLIENT_ID, GITLAB_OAUTH_REDIRECT_URI, GITLAB_API_URL
• Remote multi-user HTTP: STREAMABLE_HTTP=true, REMOTE_AUTHORIZATION=true, HOST, PORT
• Multi-pod HPA (stateless): above + OAUTH_STATELESS_MODE=true, OAUTH_STATELESS_SECRET (same across all pods). See Stateless Mode.

Commonly referenced variables:

• GITLAB_API_URL
• GITLAB_PERSONAL_ACCESS_TOKEN
• GITLAB_USE_OAUTH
• REMOTE_AUTHORIZATION
• MCP_TRUST_PROXY
• GITLAB_MCP_OAUTH
• GITLAB_OAUTH_CALLBACK_PROXY
• OAUTH_STATELESS_MODE
• OAUTH_STATELESS_SECRET

The reference document also covers:

• auth and OAuth variables
• MCP OAuth proxy variables
• project and tool filtering variables
• dynamic tool discovery via discover_tools (on-demand toolset activation)
• transport and session variables
• proxy and TLS variables

For callback proxy mode details, see GitLab MCP OAuth Callback Proxy.

Remote Authorization Setup (Multi-User Support)

When using REMOTE_AUTHORIZATION=true, the MCP server can support multiple users, each with their own GitLab token passed via HTTP headers. This is useful for:

• Shared MCP server instances where each user needs their own GitLab access
• IDE integrations that can inject user-specific tokens into MCP requests

Setup Example:

# Start server with remote authorization
docker run -d \
  -e HOST=0.0.0.0 \
  -e STREAMABLE_HTTP=true \
  -e REMOTE_AUTHORIZATION=true \
  -e GITLAB_API_URL="https://gitlab.com/api/v4" \
  -e GITLAB_READ_ONLY_MODE=true \
  -e SESSION_TIMEOUT_SECONDS=3600 \
  -p 3333:3002 \
  zereight050/gitlab-mcp

Client Configuration:

Your IDE or MCP client must send one of these headers with each request:

Authorization: Bearer glpat-xxxxxxxxxxxxxxxxxxxx

or

Private-Token: glpat-xxxxxxxxxxxxxxxxxxxx

The token is stored per session (identified by mcp-session-id header) and reused for subsequent requests in the same session.

Remote Authorization Client Configuration Example with Cursor

{
  "mcpServers": {
    "GitLab": {
      "url": "http(s)://<your_mcp_gitlab_server>/mcp",
      "headers": {
        "Authorization": "Bearer glpat-..."
      }
    }
  }
}

Important Notes:

• Remote authorization only works with Streamable HTTP transport
• Each session is isolated - tokens from one session cannot access another session's data Tokens are automatically cleaned up when sessions close
• Session timeout: Auth tokens expire after SESSION_TIMEOUT_SECONDS (default 1 hour) of inactivity. After timeout, the client must send auth headers again. The transport session remains active.
• Each request resets the timeout timer for that session
• Rate limiting: Each session is limited to MAX_REQUESTS_PER_MINUTE requests per minute (default 60)
• Capacity limit: Server accepts up to MAX_SESSIONS concurrent sessions (default 1000)

MCP OAuth Setup (Claude.ai Native OAuth)

When using GITLAB_MCP_OAUTH=true, the server acts as an OAuth proxy to your GitLab instance. Claude.ai (and any MCP-spec-compliant client) handles the entire browser authentication flow automatically — no manual Personal Access Token management needed.

Prerequisites:

A pre-registered GitLab OAuth application is required. GitLab restricts dynamically registered (unverified) applications to the mcp scope, which is insufficient for API calls (need api or read_api).

1. Go to your GitLab instance → Admin Area > Applications (instance-wide) or User Settings > Applications (personal)
2. Create a new application with:
   • Confidential: unchecked
   • Scopes: api, read_api, read_user (or whichever scopes you intend to request via GITLAB_OAUTH_SCOPES)
3. Save and copy the Application ID — this is your GITLAB_OAUTH_APP_ID

How it works:

1. User adds your MCP server URL in Claude.ai
2. Claude.ai discovers OAuth endpoints via /.well-known/oauth-authorization-server
3. Claude.ai registers itself via Dynamic Client Registration (POST /register) — handled locally by the MCP server (each client gets a virtual client ID)
4. Claude.ai redirects the user's browser to GitLab's login page using the pre-registered OAuth application
5. User authenticates; GitLab redirects back to https://claude.ai/api/mcp/auth_callback
6. Claude.ai sends Authorization: Bearer <token> on every MCP request
7. Server validates the token with GitLab and stores it per session

Server setup:

docker run -d \
  -e STREAMABLE_HTTP=true \
  -e GITLAB_MCP_OAUTH=true \
  -e GITLAB_OAUTH_APP_ID="your-gitlab-oauth-app-client-id" \
  -e GITLAB_API_URL="https://gitlab.example.com/api/v4" \
  -e MCP_SERVER_URL="https://your-mcp-server.example.com" \
  -p 3002:3002 \
  zereight050/gitlab-mcp

For local development (HTTP allowed):

MCP_DANGEROUSLY_ALLOW_INSECURE_ISSUER_URL=true \
STREAMABLE_HTTP=true \
GITLAB_MCP_OAUTH=true \
GITLAB_OAUTH_APP_ID=your-gitlab-oauth-app-client-id \
MCP_SERVER_URL=http://localhost:3002 \
GITLAB_API_URL=https://gitlab.com/api/v4 \
node build/index.js

Claude.ai configuration:

{
  "mcpServers": {
    "GitLab": {
      "url": "https://your-mcp-server.example.com/mcp"
    }
  }
}

No headers field is needed — Claude.ai obtains the token via OAuth automatically.

Environment variables:

Variable	Required	Description
GITLAB_MCP_OAUTH	Yes	Set to true to enable
GITLAB_OAUTH_APP_ID	Yes	Client ID of the pre-registered GitLab OAuth application
MCP_SERVER_URL	Yes	Public HTTPS URL of your MCP server
GITLAB_API_URL	Yes	Your GitLab instance API URL (e.g. https://gitlab.com/api/v4)
STREAMABLE_HTTP	Yes	Must be true (SSE is not supported)
GITLAB_OAUTH_SCOPES	No	Comma-separated GitLab scopes to request (e.g. api,read_user). Defaults to api (or read_api when GITLAB_READ_ONLY_MODE=true). The pre-registered application must be configured with at least these scopes.
MCP_DANGEROUSLY_ALLOW_INSECURE_ISSUER_URL	No	Set true for local HTTP dev only

Important Notes:

• MCP OAuth only works with Streamable HTTP transport (SSE=true is incompatible)
• Each user session stores its own OAuth token — sessions are fully isolated
• Session timeout, rate limiting, and capacity limits apply identically to the REMOTE_AUTHORIZATION mode (SESSION_TIMEOUT_SECONDS, MAX_REQUESTS_PER_MINUTE, MAX_SESSIONS)
• Header auth fallback: when Private-Token or JOB-TOKEN request headers are present, OAuth validation is skipped and the raw token is used directly for that session. This allows PATs and CI job tokens to be used alongside the OAuth flow on the same server instance. Authorization: Bearer is always treated as an OAuth token — use Private-Token for PAT-based header auth.

Agent Skill Files

Pre-built skill files are available in skills/gitlab-mcp/ for AI agents that support skill/instruction loading (Claude Code, GitHub Copilot, Cursor, etc.).

• SKILL.md — Core guide (~800 tokens) with toolset overview, key workflows, and parameter hints
• reference/ — Detailed workflow docs for code review, merge requests, issues, and pipelines

Install with the skills CLI:

npx skills add zereight/gitlab-mcp --skill gitlab-mcp-skill

Register the skill directory in your AI client to get optimal tool usage guidance without relying solely on the full ListTools response.
