Connect Claude & ChatGPT to Pumble

Ask your AI what was said in a channel, where a decision was made, or to post an update, and it works in your Pumble workspace. It can read channels, messages, threads, users and user groups, and search messages by text, channel or sender. It can also post, reply, send direct and group messages, schedule messages, react, edit, create channels and add people, with your approval if you want it.

Questions

What can the AI do in Pumble?

It can read users, user groups, channels, messages, threads and scheduled messages, and search messages. It can post messages and thread replies, send direct and group messages, schedule and edit messages, add reactions, create channels, add users to channels and delete messages.

Does the AI see my Pumble credentials?

No. Your Pumble credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Channel posts and direct messages are seen right away and deleting a message cannot be undone, so these can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Pumble workspace.

Who do the AI's messages come from?

The API key acts as the Pumble user who created it, so messages and reactions appear under that user's name. You can always ask the AI which user the connection acts as.
