Ask HN: Has anyone managed to implement OAuth on an MCP server?

1 pointrco87862 comments

OAuth has been officially part of the MCP spec for a few weeks. But so far, I haven't seen any examples of it in the wild. Wondering if anyone has done this, or knows of any documentation that is actually decent on how to do it.

Yep, I ran into a few issues wiring up OAuth over the last few weeks building a ChatGPT connector so built this library to help folks get up and running quickly.

Let me know if you have any questions on it

I came across https://github.com/systempromptio/systemprompt-mcp-server which has an OAuth 2.1 demo
