Bridges any GraphQL API to Claude Code — auto-generates MCP tools via schema introspection.
MCP MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Bridges any GraphQL API to Claude Code — auto-generates MCP tools via schema introspection.
A generic MCP (Model Context Protocol) server that bridges any GraphQL API to Claude Code. It introspects your GraphQL schema and exposes each query and mutation as an individual tool, letting Claude interact with your API directly.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Once MCP is connected, these are the calls the assistant has available:
execute_graphql — Generic fallback — run any query or mutation (mutations rejected if GRAPHQL_INCLUDE_MUTATIONS=false)get_type_details — Explore fields of a specific GraphQL typeYou will need 6 environment variables: GH_TOKEN, GRAPHQL_INTROSPECTION_URL, GRAPHQL_API_URL, GRAPHQL_TOKEN, GRAPHQL_INTROSPECTION_TOKEN, MCP_AUTH_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP's toolset — execute_graphql, get_type_details — is a fair guide to whether it matches your workflow. It is maintained by murilojrpereira; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
