Aircall API and MCP server

Aircall lets code tag calls, add notes, send texts and create contacts only with an API key an admin makes, and its beta agent connector is read-only. Sign in to Aircall once in your own Cloud Browser, and your AI agent does the work there for you. The same tools work over MCP for agents and as a REST API for scripts.

Aircall's own API leaves this out. So we run one for you.

How do I connect Aircall to Claude, ChatGPT or my code?

AI agents connect over MCP, scripts call the REST API. Both reach the same 11 tools with one API key.

For AI agents: MCP

Add Cotlet to your agent once. Aircall and every other app you connect show up as its tools.

    Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.

For scripts: REST API

Every tool is an endpoint under /api/v1/aircall with its own method and path, such as POST /api/v1/aircall/contacts, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the Aircall API and MCP server do?

11 tools on your own Aircall account. Agents call them as operations of the MCP tools aircall_read and aircall_write; scripts call each one at its own REST endpoint, with the same inputs and answers.

Each call uses 10 credits, and your Cloud Browser uses 50 credits a day while Aircall is enabled for agents, so 20 calls a day come to 250 credits.

Questions

Does Aircall have an API?

Aircall has a full public REST API and an official MCP server in beta (checked 23 Oct 2026). The API needs a key that a company Admin creates under Company Settings > API Keys, and it reads and writes calls, tags, comments, contacts and messages. The MCP server at mcp.aircall.io is read-only: it searches calls and call intelligence, and it cannot tag calls, send messages or change data.

How do I get access?

Sign up free, open Aircall under Integrations in the console and press Request access. Your free trial starts with your account, no card needed.

Is the MCP server different from the API?

No, only the way in. Cotlet builds each integration as a REST API and puts an MCP server on top, so both have the same 11 tools, the same inputs and answers, one API key and one price. AI agents such as Claude, ChatGPT or Cursor use MCP; scripts, cron jobs and HTTP steps in n8n, Make or Zapier use the REST API.

What is the Cloud Browser?

Your own Chrome that Cotlet runs for you in the EU, around the clock. You open it from the console, sign in to Aircall yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so Aircall sees the browser you signed in with. Password saving is off and the profile is stored encrypted with AES-256-GCM.

Can my agent act without asking me?

Not on anything that reaches other people: add_call_note, send_message, create_contact wait for your OK by default. You can switch that off per tool for scheduled runs.

Do I need an Aircall admin or an API key?

No. Cotlet works from your own signed-in Aircall Workspace seat, so it needs no API key and no Admin to make one. Your role still counts: only Admins and Supervisors create tags, the Dashboard Call History is for Admins and Supervisors, and summaries need an AI Assist add-on on your seat.

Can my agent make or answer calls?

No. The tools read call history and conversations, tag calls, add notes, send SMS and manage contacts. Calls are made and answered by people in Aircall Workspace.

When is the Aircall API the better choice?

For high volume and live events. The API allows 120 requests a minute per company and pushes call, message and contact events by webhook, while a signed-in session works at the speed of the app and polls. If you have an Admin and want that, use the API. If you do not, or want one agent tool without the build, use Cotlet.

Should I use a Aircall MCP server from GitHub instead?

Pick one if you want the code on your own computer and do not mind the upkeep: you install it, sign it in and fix it when Aircall changes. Pick Cotlet if you want it hosted and kept working for you.

Can I use it in n8n, Make or Zapier?

Yes. Add https://cotlet.dev/mcp/v1 in n8n's MCP Client node, or call the REST endpoints from an HTTP step in Make or Zapier.

Who runs Cotlet?

Cotlet is run by Take Group, a Polish software company working since 2019. Take Group runs about 3,200 websites on its own systems and has its own DevOps team for infrastructure security. We built and used integrations like this inside the company for years before opening them as Cotlet.

Is Cotlet affiliated with Aircall?

No. Cotlet is independent and not affiliated with Aircall.
