Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Retell AI works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Retell AI to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 10 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Retell AI, so you can see the experience inside your AI.

It does not authenticate your account with Retell AI. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work Retell AI owners hand off.

This MCP is built for people who need to bridge the gap between LLM logic and real-world phone conversations.

  • 01

    Founders

    They hand off the setup of autonomous receptionists or support bots to their agent.

  • 02

    Developers

    They use the MCP to prototype voice apps without building custom admin panels.

  • 03

    Workflow Orchestrators

    They use natural language to adjust agent prompts based on previous call data.

FAQ

Questions Retell AI owners ask.

  • 01

    How do I start making calls with this MCP?

    You can use the create_phone_call capability by telling your agent to dial a specific number using a provided 'from_number'.

  • 02

    Can I change how my voice agent behaves?

    Yes, you can use create_agent to make a new one or update_agent to modify the instructions of an existing agent.

  • 03

    Where can I see what happened during a call?

    You can use get_call_details to get the transcript and sentiment analysis, or list_calls to see your history.

  • 04

    Do I need to use a separate dashboard to manage my agents?

    No, this MCP allows you to manage agents, voices, and phone numbers directly through your AI client.

  • 05

    What is required to use this MCP?

    You will need a valid Retell API Key to authenticate the connection.

  • 06

    Does Retell handle the telephone lines, or do I need my own Twilio/carrier?

    Retell AI is designed to integrate seamlessly into telephony workflows but generally focuses on the conversational agent side. They provide features to list and attach numbers (list_phone_numbers), but you often purchase those numbers or link a custom SIP trunk through Retell accounts. You can run list_phone_numbers to see your currently available direct lines.

  • 07

    How do I create an outbound call programmatically with my assistant?

    Simply ask your assistant to "Call X using my Y agent." Behind the scenes, the AI relies on the create_phone_call capability, transmitting a JSON payload supplying the from_number (a Retell registered phone number), to_number (destination), and an override_agent_id parameter to assign your voice agent correctly.

  • 08

    Can the AI initiate voice calls in a web browser instead of over the phone?

    Yes. Use the register_web_call capability to create a browser-based voice session. This returns a connection URL and access token that your frontend application can use to start a real-time WebRTC conversation with a Retell voice agent, without requiring any phone line.
