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.

Cursor usa el mismo esquema mcpServers que Claude Desktop. La configuración del proyecto prevalece sobre la global.

      "command": "npx",

Haz clic en el icono MCP Servers de la barra lateral de Cline y luego en "Edit Configuration".

Mismo formato que Claude Desktop. Reinicia Windsurf para aplicar.

Continue usa un array de objetos de servidor en lugar de un mapa.

Añádelo a context_servers. Zed recarga en caliente al guardar.
