Installation

Using NPX (Recommended)

npx @evalin8/mcp-gitlab-server

Global Installation

npm install -g @evalin8/mcp-gitlab-server
# or: pnpm add -g @evalin8/mcp-gitlab-server

Local Installation

npm install @evalin8/mcp-gitlab-server
npx @evalin8/mcp-gitlab-server

Setup

GitLab Personal Access Token

1. Go to GitLab → Settings → Access Tokens
2. Create a new token with these scopes:
   • api - Full API access
   • read_user - Read user information
   • read_repository - Read repository content
3. Copy the token (starts with glpat_)

Environment Configuration

Create a .env file in your project root or set environment variables:

GITLAB_HOST=https://gitlab.com/api/v4
GITLAB_TOKEN=glpat_xxxxxxxxxxxxxxxxx

Note: GITLAB_HOST should include the full API path ending with /api/v4. For self-hosted GitLab, use https://your-gitlab.company.com/api/v4.

MCP Client Integration

Add the following configuration to your MCP client:

Claude Desktop

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Cursor/VSCode/Other MCP Clients

Add to your MCP settings configuration

{
    "mcpServers": {
        "gitlab": {
            "command": "npx",
            "args": ["-y", "@evalin8/mcp-gitlab-server"],
            "env": {
                "GITLAB_HOST": "https://gitlab.com/api/v4",
                "GITLAB_TOKEN": "glpat_your_token_here"
            }
        }
    }
}

Note: Restart your MCP client after saving the configuration.

Example Usage

import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js";
import { McpClient } from "@modelcontextprotocol/sdk/client/mcp.js";

async function example() {
    const transport = new StdioClientTransport({
        command: "npx",
        args: ["-y", "@evalin8/mcp-gitlab-server"],
    });
    const client = new McpClient(transport);
    await client.connect();

    // Create a feature branch
    await client.callTool("git_create_branch", {
        repoPath: "/path/to/repo",
        branchName: "feat/ai-integration",
        fromRef: "origin/main",
    });

    // Make changes, then commit and push
    await client.callTool("git_commit_push", {
        repoPath: "/path/to/repo",
        message: "feat: add AI integration",
        branch: "feat/ai-integration",
    });

    // Create a GitLab issue
    await client.callTool("gitlab_create_issue", {
        project: "12345",
        title: "Review AI integration feature",
        description: "Please review the new AI integration implementation",
    });

    await client.close();
}

Troubleshooting

GitLab API Issues

• 404 Error: Ensure GITLAB_HOST includes the full API path (e.g., https://gitlab.com/api/v4) and use numeric project ID
• 401 Error: Verify your token has api scope and is correctly set
• 403 Error: Check if you have sufficient permissions for the project

Git Operations

• Push hangs: Set setUpstream: false or configure Git credentials/SSH
• Authentication required: This server sets GIT_TERMINAL_PROMPT=0 to avoid interactive prompts

General Issues

• Server not responding: Check that the server process is running
• Environment variables: Ensure .env file is in the correct location
• Node.js version: Requires Node.js 18 or higher

Development

Build

npm run build

Development Mode
