Connect Claude & ChatGPT to Callers

Ask your AI how a calling campaign is going, which contacts said they were interested, or to add new people for an agent to call. Callers runs AI voice agents that phone your contacts, and through PipMCP your AI can manage agents, campaigns and contacts, read call lists, reports and recordings, set call outcomes and save notes the agent uses on later calls.

Connect Callers free

Free plan, no credit card. Takes about a minute.

Try asking

“How is the renewal campaign doing?”
The AI finds the campaign and reads its results report.
“Which contacts on agent 12 said call me later?”
It lists the agent's contacts filtered by status.
“Add Maria Jensen, +45 12 34 56 78, to the webinar follow-up agent.”
It adds the contact with name, phone number and variables. The agent may call her once it is running.

What your AI can do

Agents and campaigns

List and read agents and campaigns, rename them or change phone numbers, and start or stop calling.

Contacts and memories

List, read and add contacts, remove campaign contacts, and save memories the agent uses on later calls.

Calls and reports

List calls, get recording links, read results reports and set the outcome of a call.

“Send me the recording of the last call to contact 4411.”
It lists the calls to that contact and gets the recording link for the latest one.
“Mark call 9021 as not interested.”
It sets the call outcome to NOT_INTERESTED and whether the call reached its goal.
“Remember that Peter prefers calls after 15:00.”
It saves a memory on the contact that the agent will use in future calls.

Questions

What can the AI do in Callers?

It can list organizations, agents, campaigns, contacts and calls, read reports, recording links and contact memories, and update agents and campaigns. It can add contacts, remove campaign contacts, set call outcomes, save memories, and start or stop agents and campaigns.

Does the AI see my Callers credentials?

No. Your Callers API key is encrypted at rest and never shown to the AI. After you save it, it is 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. Starting an agent or campaign places real calls, and removing a contact changes who gets called, 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 Callers account.

Will the AI place phone calls?

Only through Callers. Starting an agent or a campaign makes it begin calling its contacts, and adding a contact to a running agent means it may call them. Switch those tools off, or require your approval, if you want the AI to only read reports and calls.
