Manage Your Retell AI Voice Agents and Calls Through Your Muse

Through a custom connector, your muse can work with a Retell AI workspace in plain words: review calls with transcripts and cost, edit voice and chat agents, route phone numbers, and start a call or a text conversation after you confirm.

What it does

The connector adds 29 tools. It can list calls and read one in full: transcript, recording address, analysis, sentiment, and cost. It can list agents and versions, update a draft agent's response engine (prompt, first message, model, tools), and publish a version live after you approve. It can list phone numbers and change which agent answers or places calls and texts on each, list voices, knowledge bases, and contacts, and check call capacity. After your yes, it can start or stop a call and start a text conversation.

How to use it

1. Start an AnythingMCP account and add the Retell AI connector.
2. Sign in to Retell AI, open Settings, then API Keys, and create or copy a key. It starts with key.
3. Copy the key into the connector settings, with no prefix added.
4. In Muse, open Settings, then Connectors, and add a custom connector with the address AnythingMCP gives you. Sign in and approve.
5. Ask the muse to review recent calls or check free call capacity before any call or agent change.

What you need

• A Muse account that can add custom connectors
• An AnythingMCP account with the Retell AI connector added
• A Retell AI account, an API key, and credit on the account for calls and texts, plus a number in Retell for outbound calls

What to watch for

• Calls and texts reach real people and are billed per minute or per message. The muse shows who will be contacted, from which number, and by which agent, and acts only after your yes.
• Only contact people who have agreed to be contacted. Rules on marketing calls and texts are strict.
• Batch calls are off at install: one request can schedule many outbound calls at once, so leave it off unless you run that kind of campaign on purpose.
• Publishing an agent version changes live calls on its numbers right away. Compare the draft with the live version first.
• Stopping a live call hangs up at once.
• The connector does not create or delete agents, buy or import numbers, or edit knowledge bases and contacts.
• This is a custom connector, and Meta does not review custom connectors. You can disconnect it in Settings at any time. The muse prepares, you decide.
