Feishu questions

How do I connect Feishu to Krypton?

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

Which plan includes Feishu?

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 Feishu 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.

Tools

With an API key, your bot gets these 5 tools. Signing in uses Feishu's own MCP server and the tools it offers. Either way, the bot asks before anything hard to undo.
