Start with custom-connectors/MCP-Streamable-HTTP/apiDefinition.swagger.json and compare it with commit d0e166e18ee71275bb6a6f0561b66b3ddd6ef9d. Reproduce the Import from Github flow using the dev branch and MCP-streamable-http connector, then validate the corrected Swagger definition; done means the connector imports without the reported securityDefinitions error.
