Retellai MCP integration
Reads back what happened on a call, places outbound callbacks, keeps voice agent knowledge bases current, and batch tests an agent before it ships.
67actions available
Three actions you can hand over today
Every action runs live through MCP. Nothing to build, nothing to maintain.
Create chat completion
Lyro generates an AI response to a user message in an active chat session. This lets support agents have conversations without manually composing each reply.
End chat
Lyro closes an active chat conversation. Support agents can terminate sessions instantly when customers are done or ready to switch channels.
Register phone call
Lyro records incoming or outgoing phone calls for custom telephony setups. Agents gain a complete record of every customer call for training and compliance.
How businesses use Retellai + Lyro
Each card is one request a support team gets, and the Retellai actions Lyro runs to close it.
Pick up where the phone call left off
When a customer messages after speaking to a voice agent, Lyro pulls that call by ID and reads its status, timestamps, and outcome, so the chat continues from what was already said instead of starting over.
Retrieve Call Details by IDRetrieve Call DetailsGet Chat DetailsPlace the callback the customer asked for
Lyro starts an outbound phone call from the right number, or opens a web call in the browser session the customer is already in, and updates the live call's dynamic variables with the context it gathered.
Create a New Outbound Phone CallCreate a New Web CallUpdate CallKeep the voice agent's knowledge current
Lyro adds a new document or URL to the knowledge base behind a voice agent and removes the source a policy change made wrong, so the phone line answers from the same material as the rest of support.
Add Sources to Knowledge BaseCreate a New Knowledge BaseDelete Knowledge Base SourceTest an agent change before it takes calls
Lyro runs a batch of defined test cases against the draft agent, reports whether the run passed, and publishes the version only once the results come back clean.

How it works
Get started in 3 steps
Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Retellai actions it has and picks the ones a request needs.
Connect Retellai
Authorize the Retellai account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Retellai actions that close it and chains as many as the request needs.
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

FAQ
Everything else about Retellai
Setup, permissions, and the limits of what Lyro can do inside Retellai.
Get Concurrency returns the organization's current concurrent call count and its limit. Lyro can check that before calling Create a New Outbound Phone Call, so a customer at a busy moment is queued or handed to a human agent instead of hitting a failed dial.
