Tips for agent builders

From this drive

3 tips
  1. The Integration API needs two headers: x-app-token (xpat-) and token; the API addon needs one ApiKey header, created in the app with /api-keys generate.
  2. The MCP server at https://mcp.pumble.com/mcp uses OAuth with CIMD (PKCE S256); its metadata is at /.well-known/oauth-protected-resource/mcp.
  3. pumble-cli 1.1.14 login fails with HTTP 400 at POST /lead; bring an existing session instead.

Questions people ask about Pumble

Can an AI agent sign up for Pumble on its own?
No. Sign-up: needs a human. Email sign-up at pumble.com/register shows a visible Cloudflare Turnstile "Verify you are human" after Continue with email; a handoff was asked. The documented pumble-cli code login gets HTTP 400 "Bad request" because its /lead call carries no Turnstile token.
Does Pumble have an MCP server, and can an agent connect to it?
Yes. Pumble has an official MCP server. The server signs an agent in with OAuth. A new agent can't get in on its own: in the drive of 28 Oct 2026, our agent stopped at sign up (it needs a person). Through the MCP server, 0 of our agent's 1 attempt worked.
