MCP GitLab Jira Server

A Model Context Protocol (MCP) server for GitLab and Jira integration. This server allows AI agents like gemini-cli to interact with your GitLab and Jira instances.

• Projects: List all accessible projects or filter them by name.
• Merge Requests: List merge requests for a project, get detailed information (including diffs), add comments, and assign reviewers.
• Pipeline/CI/CD: Get pipeline status, trigger/retry/cancel pipelines, get job details and logs.
• Branch Management: List, create, delete branches and get branch details.
• Issue Management: Create, list, update, close issues and manage comments.
• Files: Get the content of a specific file at a given SHA.
• Releases: List all releases for a project or filter them since a specific version.
• Users: List project members, get a user's ID by username, and get user activities.

• Tickets: Get detailed information about a ticket, get comments, add comments, search for tickets using JQL, create new tickets, get available transitions, update tickets, and transition tickets to a new status.
• Project Management: Get all projects, project details, components, and versions.

• Node.js 18+
• GitLab Personal Access Token with API access
• Jira API Token
• Access to a GitLab instance (on-premise or GitLab.com)
• Access to a Jira instance

1. Install the package globally:

   npm i -g mcp-gitlab-jira

2. Set up environment variables:

   # GitLab
   export GITLAB_URL="https://your-gitlab-instance.com"
   export GITLAB_ACCESS_TOKEN="your-personal-access-token"
   
   # Jira
   export ATLASSIAN_SITE_NAME="your-atlassian-site-name"
   export ATLASSIAN_USER_EMAIL="your-email@example.com"
   export ATLASSIAN_API_TOKEN="your-jira-api-token"

3. Test the server manually:

   # Test that the server starts without errors
   echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}' | mcp-gitlab-jira

   The server should start and log "GitLab/Jira MCP server started" to stderr.

Create or update your MCP configuration file (usually ~/.mcp/config.json or similar):

{
  "mcpServers": {
    "gitlab-jira-mcp": {
      "command": "mcp-gitlab-jira",
      "env": {
        "GITLAB_URL": "https://your-gitlab-instance.com",
        "GITLAB_ACCESS_TOKEN": "your-personal-access-token",
        "ATLASSIAN_SITE_NAME": "your-atlassian-site-name",
        "ATLASSIAN_USER_EMAIL": "your-email@example.com",
        "ATLASSIAN_API_TOKEN": "your-jira-api-token"
      }
    }
  }
}

You can also run this MCP server in a Docker container using the pre-built image from Docker Hub.

The Docker images are automatically built and published to Docker Hub for each release:

• Latest release: hainanzhao/mcp-gitlab-jira:latest
• Specific versions: hainanzhao/mcp-gitlab-jira:v0.1.2, hainanzhao/mcp-gitlab-jira:v0.1.1, etc.
• View all available tags: Docker Hub - mcp-gitlab-jira

The images are built for multiple architectures: linux/amd64 and linux/arm64 (Apple Silicon compatible).

1. Pull and run the Docker container:

   docker run -d --name mcp-gitlab-jira-container \
     -e GITLAB_URL="https://your-gitlab-instance.com" \
     -e GITLAB_ACCESS_TOKEN="your-personal-access-token" \
     -e ATLASSIAN_SITE_NAME="your-atlassian-site-name" \
     -e ATLASSIAN_USER_EMAIL="your-email@example.com" \
     -e ATLASSIAN_API_TOKEN="your-jira-api-token" \
     hainanzhao/mcp-gitlab-jira:latest

2. Alternative: Run without persistent container (one-time execution):

   docker run --rm -i \
     -e GITLAB_URL="https://your-gitlab-instance.com" \
     -e GITLAB_ACCESS_TOKEN="your-personal-access-token" \
     -e ATLASSIAN_SITE_NAME="your-atlassian-site-name" \
     -e ATLASSIAN_USER_EMAIL="your-email@example.com" \
     -e ATLASSIAN_API_TOKEN="your-jira-api-token" \
     hainanzhao/mcp-gitlab-jira:latest

You have two options for using the Docker container with MCP clients:

First, start the container as shown above, then update your MCP configuration file. The env block is empty because the necessary environment variables are passed directly to the container using the -e flag in the docker run command.

{
  "mcpServers": {
    "gitlab-jira-mcp": {
      "command": "docker",
      "args": ["exec", "-i", "mcp-gitlab-jira-container", "npm", "start"],
      "env": {}
    }
  }
}

This runs a new container for each MCP session:

{
  "mcpServers": {
    "gitlab-jira-mcp": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "-e", "GITLAB_URL=https://your-gitlab-instance.com",
        "-e", "GITLAB_ACCESS_TOKEN=your-personal-access-token",
        "-e", "ATLASSIAN_SITE_NAME=your-atlassian-site-name",
        "-e", "ATLASSIAN_USER_EMAIL=your-email@example.com",
        "-e", "ATLASSIAN_API_TOKEN=your-jira-api-token",
        "hainanzhao/mcp-gitlab-jira:latest"
      ],
      "env": {}
    }
  }

1. "Cannot find module" errors: If you are developing locally, make sure you've run npm install and npm run build.
2. Authentication errors: Verify your GITLAB_ACCESS_TOKEN, ATLASSIAN_USER_EMAIL, and ATLASSIAN_API_TOKEN have the necessary permissions.
3. Connection errors: Ensure your GITLAB_URL and ATLASSIAN_SITE_NAME are correct and accessible.
4. Server not responding: Check that the MCP server process is running and the path in your config is correct.

To see detailed logs, you can run the server directly:

export GITLAB_URL="your-url"
export GITLAB_ACCESS_TOKEN="your-token"
export ATLASSIAN_SITE_NAME="your-atlassian-site-name"
export ATLASSIAN_USER_EMAIL="your-email@example.com"
export ATLASSIAN_API_TOKEN="your-jira-api-token"
mcp-gitlab-jira

For development, clone the repository and install the dependencies.
