Everything about hitch-rails routes through GitHub, where the conversation is public and searchable — the next person with your question can find the answer.
Bugs and unexpected behavior
Open an issue on the issue tracker. Include the gem version, the Rails version, and what the client (Claude, ChatGPT, Cursor, or another MCP client) actually did versus what you expected. Conformance findings — places where behavior diverges from OAuth 2.1 or the MCP authorization spec — are especially welcome, and citing the RFC or spec section gets a fix moving fastest.
Questions and ideas
Also the issue tracker. There is no support contract or SLA behind this gem; there is a maintainer who reads every issue.
Security reports
For a vulnerability in the gem itself, please use GitHub’s security reporting for the repository rather than a public issue, so a fix can ship before the details do.
