Retell AI MCP server
AI voice and chat agents with your choice of LLM (Claude, GPT, Gemini): three meta-tools (list endpoints, get schema, invoke) that reach the whole Retell API, so agents, calls, numbers, knowledge bases and batch tests. Claude.ai directory connector signs in with OAuth and picks a workspace; the raw URL takes a Bearer API key only and answers initialize anonymously (probed 10/19, no OAuth discovery). No confirmation gating: approve invoke_api_endpoint per call. Added 10/19 for the Vapi vs Bland vs Retell comparison in docs/voice-agents.
Can anyone connect?
Needs a key or vendor setup. The server asks for credentials but publishes no self-serve login, so it wants an API key in a header or an OAuth client you create with the vendor yourself.
Who runs it: Vendor-run. The MCP host is the product's own domain, so the company behind the product runs the server and the only data exposed is data already in your account with them.
Listed by its source as: Sign in with your own account. The live check disagrees, trust the check.

Before you connect
- The verdict is about the door, not the house. Our check proves the server answers and whether it lets you sign in. It says nothing about what the server does with your data or what its tool results contain.
- Tool results can carry hidden instructions. Everything a server returns is text Claude reads. A bad server can bury an instruction in it, such as searching your inbox and sending what it finds back out. So never run an unknown server in the same chat as Gmail, Drive, Slack or Stripe.
- Keep write confirmations on. Claude asks before a connector sends, posts, pays or deletes. Leave that on for any server you do not know, and read its tool list before you say yes.
- Everything you pass goes to that server. A document you ask Claude to run through a tool is now on that company's machine. Try an unknown server on a throwaway question first.
- Servers change. A server can swap its tools next week. Re-check before you rely on one, and disconnect what you stop using under Settings, Connectors.
