MCP Server With OAuth 2.1
Your MCP server works when you try it once. Here is what it does in real use.
Payment and file delivery by Polar. The receipt and the download link arrive by email.
One shared key in every client configuration cannot be revoked, cannot be attributed and never expires.
What you get
- A credential ledger you can switch off, one client at a time
- OAuth 2.1 with PKCE and refresh rotation, built on RFC 7636 and RFC 7009
- Self registering clients that still need a human to approve them
- Tokens bound to the one server they were issued for
- A stateless Streamable HTTP transport and a tool structure that scales
- The runbook for the day a token outlives its client
