Graphql MCP Server

Graphql MCP server exists for a simple reason — assistants are far more useful when they can act on Graphql directly instead of describing what you should do. GraphQL IDE for better development workflows (GraphQL Subscriptions, interactive docs & collaboration).

What you get

• ✨ Context-aware autocompletion & error highlighting
• 📚 Interactive, multi-column docs (keyboard support)
• ⚡️ Supports real-time GraphQL Subscriptions
• ⚙ GraphQL Config support with multiple Projects & Endpoints
• 🚥 Apollo Tracing support

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

What the assistant can call

Once Graphql is connected, these are the calls the assistant has available:

• Express — ** See [packages/graphql-playground-middleware-express/examples/basic](https://github.com/prismagraphql/graphql-playground/tree/main/packages/graphql-
• Hapi — ** See [packages/graphql-playground-middleware-hapi](https://github.com/prismagraphql/graphql-playground/tree/main/packages/graphql-playground-middlew
• Koa — ** See [packages/graphql-playground-middleware-koa](https://github.com/prismagraphql/graphql-playground/tree/main/packages/graphql-playground-middlewa
• Impact — The only reason this vulnerability exists is because we are using template strings in renderPlaygroundPage() with potentially unsanitized user
• Properties — The React component and all middlewares expose the following options:
• Usage — exports.graphqlHandler = function graphqlHandler(event, context, callback) { function callbackFilter(error, output) { // eslint-disable-next-line
• Versions — The Versions tool exposed by this server
• Packages — In the folder packages you'll find the following packages:

Before you rely on it

• Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the graphql mcp server does with a few real requests.

Choosing this one

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Graphql's toolset — Express, Hapi, Koa and 5 more — is a fair guide to whether it matches your workflow. It is maintained by apollo-bot; worth a glance at recent repository activity before you build anything load-bearing on it.
