Model Context Protocol

MCP is a new protocol, launched in November 2024 by Anthropic, designed to make structured data explorable and actionable via natural language. Grafbase offers MCP support out of the box - removing the need to stand up your own standalone MCP server, configure authentication, or fine-tune access control.

Get started with Cursor

The Grafbase MCP server can be started with the Grafbase CLI by running:

npx grafbase mcp <url>

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
