OpenAPI Proxy FAQs

Question 1

What is OpenAPI Proxy?

Accepted Answer

OpenAPI Proxy is a standalone tool that transforms any OpenAPI/Swagger-described HTTP API into an MCP (Model Context Protocol) server, dynamically generating a distinct MCP tool for each of your API endpoints.

Question 2

Can I control which API endpoints are exposed as MCP tools?

Accepted Answer

Yes, it offers precise control. You can configure endpoint filtering using environment variables like MCP_INCLUDE_ENDPOINTS (to only expose specific endpoints) or MCP_EXCLUDE_ENDPOINTS (to ignore certain ones).

Question 3

What are the deployment options for OpenAPI Proxy?

Accepted Answer

OpenAPI Proxy can be deployed locally using npm, or for simplified and scalable setups, it integrates seamlessly with Docker and Docker Compose.

Question 4

What kind of communication does it support for MCP clients?

Accepted Answer

OpenAPI Proxy utilizes Streamable HTTP transport, allowing MCP clients to seamlessly communicate with the server via standard POST or GET requests to the /mcp endpoint.

Question 5

How does OpenAPI Proxy generate MCP tools from my API spec?

Accepted Answer

It loads your OpenAPI/Swagger specification at startup, intelligently filters API operations based on configurable include/exclude rules, and then registers a unique MCP tool for each selected API operation.
