description: 'OpenAPI Generator publishes NO official hosted or remote MCP server. Searched on 2026-08-06:
  no /.well-known/* MCP or OAuth discovery document on either openapi-generator.tech or api.openapi-generator.tech
  (all 404), no MCP entry in the project docs navigation, and no MCP endpoint referenced from the Online
  Generator docs. The tool list below is a CANDIDATE derived from the seven real operations in the published
  Swagger document — it describes what an MCP server over this API would expose, and is not a claim that
  one exists.'

caveats:
- Not a published server. Do not present this tool list as an OpenAPI Generator product.
- download_generated_artifact returns a zip stream, which is a poor fit for an MCP text/JSON tool result
  — a real server would need to return the download URL instead.
- Generated artifacts are transient; an expired fileId returns 500, not 404.
