Summary

AI summary

OpenAI Apps domain verification added via hosted MCP and Cloud Run playbook.

Full changelog

Added

  • OpenAI Apps domain verification for hosted MCP. HTTP mode now serves the raw
    OPENAI_APPS_CHALLENGE_TOKEN from /.well-known/openai-apps-challenge, allowing
    ChatGPT Apps domain verification against Cloud Run and other HTTPS-hosted MCP origins without
    committing the token.
  • Cloud Run verification playbook. deploy/cloud-run documents the Challenge Base URL shape,
    token environment variable, and curl check for ChatGPT Apps verification, and the wrapper now
    tracks the semiotic@^3.7.3 release line.

Tests

  • Added MCP HTTP regression coverage for the OpenAI Apps challenge route while confirming the
    unauthenticated OAuth protected-resource probe continues to return 404.
