Summary

MCPHub v1.2.1 improves upstream connection stability and OpenAPI parameter compatibility, adds narrowly scoped Fake-IP exceptions, and restores Authorization passthrough through an explicit administrator opt-in. It also refreshes package versions more promptly after reinstall or reload and updates dependencies.

Highlights

Fixes

  • Restore upstream Authorization passthrough through an explicit admin opt-in, disabled by default; requires a separate MCPHub authentication header and trusted upstream configuration, and remains unavailable in hosted mode. by @samanhappy in https://github.com/samanhappy/mcphub/pull/1453
  • Refresh package versions and update hints promptly after Reinstall or Reload. by @samanhappy in https://github.com/samanhappy/mcphub/pull/1451
  • Preserve upstream connections when changing tool, prompt or resource settings, avoiding duplicate stdio processes while servers are connecting. by @11113127 in https://github.com/samanhappy/mcphub/pull/1449
  • Handle nullable and union tool schemas in OpenAPI and convert scalar array inputs correctly; affected generated operations now use POST with a JSON body. by @OsamaAnsar in https://github.com/samanhappy/mcphub/pull/1447
  • Update runtime and development dependencies, including OpenAI, Hugging Face tokenizers, uuid, tailwind-merge, i18next-browser-languagedetector and concurrently.
