Frequently asked questions

1

What are the runtime requirements?

Node.js >= 16.17.0 and an MCP client such as Claude Desktop or Cursor.

2

Does the server execute API endpoints as tools?

No. OpenAPI MCP v2 focuses on exploration and providing context; it does not allow executing endpoints directly because authentication is not yet solved.

3

Where does the data come from?

The server searches and explores OpenAPI specifications through oapis.org.

4

What transports / authentication does it use?

The README does not detail specific transports; it notes that authentication for endpoint execution is not yet solved with MCP.

5

Is this version stable?

It is a Work In Progress. Expect bugs and contributions are welcome.
