Meta & GraphQL
July 26, 2026 · View on GitHub
Tools the MCP exposes that aren't tied to a specific GitLab feature group — server diagnostics and the GraphQL escape hatch.
!!! note "Feature toggle"
Mixed availability. discover_tools is always exposed (the server re-adds it after every toolset filter). execute_graphql is not part of any toolset — enable it explicitly with GITLAB_TOOLS=execute_graphql.
