Connect Claude & ChatGPT to Tars
Ask your AI to look up the people your Tars agents talk to, tag them or add new ones. It can send a WhatsApp message or a campaign template to a phone number, check a campaign send for errors first, and start a conversation at a trigger point in one of your agent flows.
Free plan, no credit card. Takes about a minute.

Questions
What can the AI do in Tars?
It can list, read, create, update and delete end users. It can send WhatsApp messages and campaign messages, check a campaign send for errors without sending it, and start a conversation with an end user at a trigger point in an agent flow.
Does the AI see my Tars API key?
No. Your Tars 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 with lookups only. Sending messages, starting agent conversations and deleting end users can require your approval before they run. Deleting an end user is permanent. 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 Tars account, and Tars says API access requires a paid Tars plan.
Can the AI send any WhatsApp message?
Inside an open conversation window it can send a plain text message. Outside that window it has to use an approved WhatsApp template with its name and language. Either way the message is delivered immediately, so you may want sending to require your approval.
