Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Aircall account to Claude via Composio Connect, enabling it to list recent missed calls from Aircall, find contacts created this week in Aircall, tag unanswered calls for sales follow-up, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Aircall account

Back in Claude, ask it to connect to Aircall or give it any Aircall-related task.

For example, ask Claude to:

  • "List recent missed calls from Aircall"
  • "Find contacts created this week in Aircall"
  • "Tag unanswered calls for sales follow-up"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Aircall account is ready to use.

What is the Aircall Claude Connector, and what's possible with it?

The Aircall MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Aircall account. It provides structured and secure access to your Aircall calls, users, teams, phone numbers, contacts, tags, and webhooks, so your agent can place calls, search call activity, manage contacts and teams, check user availability, and control call features on your behalf.

  • Call handling and insight: Have your agent place outbound calls, find calls by direction, user, phone number, tags, or date, add comments, manage recording during ongoing calls, delete call audio, and publish insight cards for call agents.
  • Contact management: Let the agent search, create, view, and delete shared contacts, then add or remove their phone numbers and email addresses.
  • User and team administration: Direct your agent to list, create, view, and delete users, create or remove teams, change team membership, and check user availability.
  • Phone numbers and tags: Instruct your agent to list and inspect Aircall phone numbers, check registration status, and create, view, list, or delete call tags.
  • Webhook management: Have your agent create, list, inspect, or delete Aircall webhooks for connected HTTPS destinations.

Troubleshooting

1. Why does Claude not use the Composio connector for Aircall?

The connector can show as connected, but Claude must use it in each Aircall conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Aircall again.

2. Why does Claude show an MCP server error before Aircall connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Aircall.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Aircall.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Aircall authorization link not work?

The Composio connector is one server. Your Aircall account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Aircall connection.
  • Composio creates a fresh Aircall authorization link.
  • Open that link in your browser and finish the Aircall sign-in.

4. Why do Aircall actions fail after they worked before?

The Aircall connection can expire or lose permission.

  • Ask Claude to inspect the Aircall connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Aircall account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Aircall.
  • If the action still fails with a permission error, check that the connected account has that permission in Aircall itself.

5. How do I switch to a different Aircall account?

Claude can manage the Aircall connection for you.

  • Ask Claude to disconnect or delete the current Aircall account.
  • Ask Claude to connect Aircall again.
  • Open the new Composio authorization link for Aircall.
  • Sign in with the other Aircall account in the browser.
  • After the account connects, ask Claude to retry the Aircall task.

6. Why is my Aircall connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Aircall connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Aircall tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Aircall.

FAQ

Frequently asked questions

With a standalone Aircall MCP server, the agents and LLMs can only access a fixed set of Aircall tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Aircall and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Aircall tools.

Yes, absolutely. You can configure which Aircall scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Aircall data and credentials are handled as safely as possible.
