Grafbase MCP server
This crate contains the implementation of the Model Context Protocol in Grafbase Gateway. You can find details on how to use it in the docs page.
Getting started
The Grafbase MCP server can be started with the Grafbase CLI by running:
npx grafbase mcp <url>
Where <url> is the URL of your GraphQL API.
The MCP server listens to requests at http://127.0.0.1:5000/mcp by default. To add it to Cursor, create a .cursor/mcp.json file in your project with the following:
{
"mcpServers": {
"my-graphql-api": {
"url": "http://127.0.0.1:5000/mcp"
}
}
}
Setting up MCP in the Grafbase Gateway
The Grafbase Gateway can be configured to expose a MCP endpoint with the following grafbase.toml configuration:
[mcp]
enabled = true # defaults to false
# Path at which to expose the MCP service
path = "/mcp"
# Whether mutations can be executed
execute_mutations = false
Also see the integration tests.
