Connect AI agents to GraphQL APIs through the Model Context Protocol with built-in introspection and operation tools. Apollo MCP Server exposes GraphQL operations as MCP tools, enabling AI agents to interact with GraphQL APIs through the Model Context Protocol. Create config.yaml in your project root: Start the server: The MCP endpoint is available at (streamable_http defaults: address 127.0.0.1 , port 8000 ). The GraphQL endpoint defaults to — override with the endpoint key if your API runs elsewhere. Add to your MCP client configuration: Streamable HTTP (recommended): Claude Desktop ( claude_desktop_config.json ): Claude Code: Stdio (client launches the server directly): Claude Desktop ( claude_desktop_config.json ) or Claude Code ( .mcp.json ): Apollo MCP Server provides four introspection tools: MCP tools are created from GraphQL operations. Three methods: Each file must contain exactly one operation. Each named operation becomes an MCP tool. Use GraphOS Studio to manage operations collaboratively.
