FastMCP FAQs

Question 1

What types of services can FastMCP integrate with?

Accepted Answer

FastMCP is designed to integrate with any REST service that exposes an OpenAPI document. It offers specific configuration and auto-discovery features for EMPI Java/Spring services.

Question 2

How can I update the OpenAPI specification without restarting FastMCP?

Accepted Answer

FastMCP includes a built-in maintenance tool named 'reload_openapi_spec'. Invoking this tool will instruct the server to re-fetch the OpenAPI specification and dynamically rebuild its list of available MCP tools.

Question 3

Can FastMCP handle custom HTTP headers like x-group or x-hospital?

Accepted Answer

Yes, FastMCP supports injecting custom HTTP headers. You can configure default headers via environment variables (e.g., DEFAULT_X_GROUP) or override them by passing explicit headers in a tool call argument.

Question 4

What is FastMCP?

Accepted Answer

FastMCP is a Model Context Protocol (MCP) server that dynamically converts your existing REST API endpoints into MCP tools by reading their OpenAPI specifications, enabling seamless integration.

Question 5

How does FastMCP automate tool generation?

Accepted Answer

FastMCP fetches the OpenAPI spec from your service (e.g., Spring Boot's /v3/api-docs) and automatically converts each operationId into an MCP tool, generating an appropriate input schema from parameters and request bodies.
