What is OpenAPI MCP Server?
This service acts as a stateless proxy between MCP clients and OpenAPI-documented APIs. It requires basic endpoint configuration, which is passed as a base64url-encoded JSON object in the URL.
How to use OpenAPI MCP Server?
To use the server, you need to create a configuration payload containing the OpenAPI schema URL and the API base URL. This payload is then converted to a base64url-encoded string and appended to the server's URL. The resulting URL can then be used with various tools that support MCP servers.
