Add the GitLab MCP server to Codex

Work with GitLab issues, merge requests, pipelines and code search.

Official serverRemoteDeveloper tools

1. Add the server

Run in your terminal

codex mcp add gitlab --url https://gitlab.com/api/v4/mcp

2. Sign in

Run codex mcp login <name> to complete OAuth for a remote server. GitLab is hosted by GitLab, so there is nothing to install or keep updated.

3. Try it

Ask Codex for something GitLab can do. Work with GitLab issues, merge requests, pipelines and code search. Approve the first tool call and check the result before allowing write actions automatically.

· Each server is a [mcp_servers.<name>] table in config.toml.
· Use enabled_tools or disabled_tools to keep the tool list short.
