Claude & ChatGPT Connector (MCP)

Build and run your AI phone agents straight from Claude or ChatGPT — over a secure, one-time OAuth connection.
The Famulor connector lets you build and operate your AI phone agents straight from Claude or ChatGPT. Instead of clicking through the dashboard, you just describe what you want — and your AI assistant does it on your account:
  • “Create an inbound receptionist that books appointments.”
  • “Show me why my last campaign call failed.”
  • “Add three leads to my follow-up campaign and start it.”
It’s a remote MCP server secured with OAuth 2.0. You connect once, sign in to approve, and every action stays scoped to your own Famulor account — the connector only ever sees and changes your data.

​
What you can do

Build & refine assistants

Inbound and outbound: system prompt, voice, language, model and call behaviour. Attach knowledge bases (your documents) and mid-call tools (live API lookups during a call).

Run outbound campaigns

Create campaigns, add and manage leads, and start, pause or resume them.

Review & improve

List calls, read full transcripts and post-call evaluations, then update the assistant or its tools — a complete build → review → improve loop.

Manage your account

Knowledge bases & documents, phone numbers & SIP trunks, WhatsApp senders & templates, conversations, folders, labels, API keys and your blacklist.
Read and write are separate tools. Actions that spend balance (placing a call, sending SMS/WhatsApp, buying a number) or delete data always ask for confirmation first. Integration secrets (e.g. auth tokens on your mid-call tools) are masked in responses.

​
Before you start

  • A Famulor account at app.famulor.de.
  • An active plan for the features you use (some actions consume call minutes or chat credits).
This is the secure address Claude and ChatGPT use to reach your account. Copy it — you’ll paste it during setup, then sign in to approve.

Once the connector is listed in the Claude and ChatGPT directories, you’ll also be able to add it in one click by searching for Famulor under Settings → Connectors — no manual URL needed.

​
Try it

Start a new chat in Claude or ChatGPT and ask, for example:

Build

“Create an inbound receptionist for my dental clinic that books appointments and answers FAQs.”

Improve

“Read my last 5 calls and tell me what my assistant got wrong.”

Integrate

“Create a mid-call tool that looks up an order by number from our API.”

Run

“Set up an outbound campaign for this week’s leads and start it.”

​
Security & privacy

  • OAuth 2.0 with a branded consent screen — no API key is ever pasted into the chat client.
  • Scoped to your account — the connector can only see and change your own data.
  • Secrets masked — auth tokens stored on your tools are never returned in plain text.
  • No chat-history harvesting — the connector acts only on your Famulor resources.
  • Privacy policy: famulor.io/privacy.

FAQ

This guide covers Claude and ChatGPT. The connector is a standard remote MCP server, so it also works with any other MCP-compatible client (for example Cursor or VS Code) — the setup is the same: add a custom connector and paste your connection link. See also MCP Client.
No. Connection is handled by OAuth — you simply sign in to your Famulor account and approve. No key is pasted into the chat app.
Yes. Every tool is scoped to your own authenticated account, write and destructive actions ask for confirmation, and any integration secrets you’ve stored are masked in responses.
Only when you explicitly ask it to place a call or send an SMS/WhatsApp — and it confirms first. Building and editing assistants, reading calls, and managing your account don’t place calls.
This block comes from OpenAI’s own safety layer inside ChatGPT, not from Famulor. When ChatGPT is about to trigger a tool that places a real outbound phone call, OpenAI’s policy on AI agents initiating phone calls stops it before the request ever reaches us. We can’t override OpenAI’s decision from our side, and it mainly affects the ChatGPT browser.Things that work:
  • ChatGPT desktop app or an OpenAI agent — the same call goes through there.
  • Claude — the call works there too, including placing a reminder call through the assistant.
  • Schedule an outbound campaign — for reminder calls (“call John at 16:00”), set up a scheduled outbound campaign (assistant + contact + time) from the dashboard or via the API / Automate. It never goes through ChatGPT’s safety layer, so it’s never blocked.
A native ChatGPT integration is in review with OpenAI and coming soon.
