GitHub MCP vs GitLab MCP: Which Source Control Server Should You Use?

Connecting your AI assistant directly to your source control platform is one of the highest-leverage MCP servers you can add. Instead of switching tabs to check PR status, look up issues, or trigger pipelines, your assistant handles it inline. The question is which server -- and for GitLab users, which option -- to use.

GitHub MCP

Author: Anthropic | Tools: 20 | Requires: GitHub personal access token

The straightforward choice for GitHub users. Twenty tools cover the operations most developers actually need: issues, PRs, repo search, file CRUD, branches, and workflows. Maintained alongside Claude, regularly updated, and efficient at ~10,300 tokens.

{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_your_token_here"
      }
    }
  }
}

Generate a fine-grained token from GitHub Settings > Developer Settings > Personal Access Tokens. Scope permissions to what you actually need.

GitLab MCP: Two Options

Option 1: GitLab's First-Party Server

Built into GitLab 18.6+, 15 tools, OAuth 2.0 auth. Includes semantic code search via GitLab Duo. Catch: requires GitLab Duo (paid feature).

{
  "mcpServers": {
    "gitlab": {
      "type": "http",
      "url": "https://gitlab.com/api/v4/mcp"
    }
  }
}

For clients without HTTP transport, use the stdio bridge:

{
  "mcpServers": {
    "gitlab": {
      "command": "npx",
      "args": ["mcp-remote", "https://gitlab.com/api/v4/mcp"]
    }
  }
}

Option 2: Community GitLab MCP (@zereight/mcp-gitlab)

69+ tools across MRs (31), issues (14), repos (7), branches (4), projects (8), labels (5), plus optional modules. Over 1,100 GitHub stars. Use GITLAB_TOOLSETS to filter which tools load.

{
  "mcpServers": {
    "gitlab": {
      "command": "npx",
      "args": ["-y", "@zereight/mcp-gitlab"],
      "env": {
        "GITLAB_PERSONAL_ACCESS_TOKEN": "glpat-your_token_here",
        "GITLAB_API_URL": "https://gitlab.com",
        "GITLAB_TOOLSETS": "merge_requests,issues,pipelines"
      }
    }
  }
}

Token Budget

GitHub MCP uses ~10,300 tokens for 20 tools -- reasonable alongside other servers. The community GitLab MCP at 69+ tools will be substantially heavier, but GITLAB_TOOLSETS filtering keeps it manageable. Enable what you use, disable what you do not.

Which Should You Use

You use GitHub. Use GitHub MCP. Official, well-maintained, token-efficient. No real alternative to consider.

You use GitLab with Duo. Start with the first-party server. If the 15-tool set is too limiting, add the community server.

You use GitLab without Duo. Use the community server. Enable only needed toolsets to manage token budget.

You use both. Run both servers. Limit GitLab toolsets if you are also running other MCP servers.
