## Questions

### How do I connect Clerk to Krypton?

Open Integrations in Krypton, find Clerk and choose Sign in. Every bot in the workspace can then use it, and you choose which bots get which apps.

### Which plan includes Clerk?

MCP only with 2,000 calls a month, Pro and Max with 20,000. Calls are shared by every catalog app in the workspace. Past the monthly number they keep working from AI credits at $0.90 per 1,000 calls; the count resets on the 1st (UTC) and a retried call counts once.

### Can I use Clerk from Claude or Cursor?

Yes. Connect it in your workspace, then add https://mcp.krypton.bot as a streamable HTTP MCP server with your kmcp_ workspace key. Calls count toward the same monthly number.
