From the repository
npx mcp-graphql --endpoint http://localhost:3000/graphql
To install GraphQL MCP Server for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install mcp-graphql --client claude
It can be manually installed to Claude:
{
"mcpServers": {
"mcp-graphql": {
"command": "npx",
"args": ["mcp-graphql", "--endpoint", "http://localhost:3000/graphql"]
}
}
}
introspect-schema
This tool retrieves the GraphQL schema. Use this first if you don't have access to the schema as a resource. It 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-mutations' is specified.
The server provides two main tools:
1. 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.
2. query-graphql: Execute GraphQL queries against the endpoint. By default, mutations are disabled unless --enable-mutations is specified.
