Provides a bridge to GraphQL APIs, enabling schema introspection and query execution. Allows models to discover and interact with GraphQL endpoints dynamically, with optional support for mutation operations.
mcp-graphql
A Model Context Protocol server that enables LLMs to interact with GraphQL APIs. This implementation provides schema introspection and query execution capabilities, allowing models to discover and use GraphQL APIs dynamically.
Usage
Run mcp-graphql with the correct endpoint, it will automatically try to introspect your queries.
Command Line Arguments
| Argument | Description | Default |
|---|---|---|
--endpoint | GraphQL endpoint URL | http://localhost:4000/graphql |
--headers | JSON string containing headers for requests | {} |
--enable-mutations | Enable mutation operations (disabled by default) | false |
--name | Name of the MCP server | mcp-graphql |
--schema | Path to a local GraphQL schema file (optional) | - |
Examples
Available Tools
The server provides two main tools:
- introspect-schema: This tool retrieves the GraphQL schema. Use this first if you don't have access to the schema as a resource. This uses either the local schema file or an introspection query.
- query-graphql: Execute GraphQL queries against the endpoint. By default, mutations are disabled unless
--enable-mutationsis specified.
Resources
- graphql-schema: The server exposes the GraphQL schema as a resource that clients can access. This is either the local schema file or based on an introspection query.
Installation
Installing via Smithery

Installing Manually
It can be manually installed to Claude:
Security Considerations
Mutations are disabled by default as a security measure to prevent an LLM from modifying your database or service data. Consider carefully before enabling mutations in production environments.
Customize for your own server
This is a very generic implementation where it allows for complete introspection and for your users to do whatever (including mutations). If you need a more specific implementation I'd suggest to just create your own MCP and lock down tool calling for clients to only input specific query fields and/or variables. You can use this as a reference.
This server cannot be installed
hybrid server
The server is able to function both locally and remotely, depending on the configuration or use case.
