GitLab MCP

Name: GitLab MCP MCP Server
Author: zereight

Treat GitLab like the GitHub MCP treats GitHub — issues, MRs, pipelines, comments — with explicit support for self-hosted instances.

Zereight's GitLab MCP is the de-facto community implementation. It covers REST and a curated GraphQL surface, supports self-hosted GitLab via GITLAB_API_URL, and has fine-grained read/write tool gating.

Installieren

Wählen Sie Ihren Client

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

{
  "mcpServers": {
    "gitlab-mcp-zereight": {
      "command": "npx",
      "args": [
        "-y",
        "@zereight/mcp-gitlab"
      ],
      "env": {
        "GITLAB_PERSONAL_ACCESS_TOKEN": "${GITLAB_TOKEN}",
        "GITLAB_API_URL": "https://gitlab.com/api/v4"
      }
    }
  }
}

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "gitlab-mcp-zereight": {
      "command": "npx",
      "args": [
        "-y",
        "@zereight/mcp-gitlab"
      ],
      "env": {
        "GITLAB_PERSONAL_ACCESS_TOKEN": "${GITLAB_TOKEN}",
        "GITLAB_API_URL": "https://gitlab.com/api/v4"
      }
    }
  }
}

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "gitlab-mcp-zereight": {
      "command": "npx",
      "args": [
        "-y",
        "@zereight/mcp-gitlab"
      ],
      "env": {
        "GITLAB_PERSONAL_ACCESS_TOKEN": "${GITLAB_TOKEN}",
        "GITLAB_API_URL": "https://gitlab.com/api/v4"
      }
    }
  }
}

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "gitlab-mcp-zereight": {
      "command": "npx",
      "args": [
        "-y",
        "@zereight/mcp-gitlab"
      ],
      "env": {
        "GITLAB_PERSONAL_ACCESS_TOKEN": "${GITLAB_TOKEN}",
        "GITLAB_API_URL": "https://gitlab.com/api/v4"
      }
    }
  }
}

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "gitlab-mcp-zereight",
      "command": "npx",
      "args": [
        "-y",
        "@zereight/mcp-gitlab"
      ]
    }
  ]
}

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

{
  "context_servers": {
    "gitlab-mcp-zereight": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "@zereight/mcp-gitlab"
        ]
      }
    }
  }
}

In context_servers hinzufügen. Zed lädt beim Speichern neu.

claude mcp add gitlab-mcp-zereight -- npx -y @zereight/mcp-gitlab

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.
