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 Circleback account to Claude via Composio Connect, enabling it to summarize meeting transcripts from last week, find action items assigned to me today, list calendar conflicts across your meetings, 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 Circleback account

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

For example, ask Claude to:

  • "Summarize meeting transcripts from last week"
  • "Find action items assigned to me today"
  • "List calendar conflicts across your meetings"

It will prompt you to authenticate and authorize access.

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

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

The Circleback MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Circleback account. It provides structured and secure access so your agent can perform Circleback operations on your behalf.

Troubleshooting

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

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

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

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

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

  • 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 Circleback.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Circleback authorization link not work?

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

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

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

The Circleback connection can expire or lose permission.

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

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

Claude can manage the Circleback connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If Circleback 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 Circleback.

FAQ

Frequently asked questions

With a standalone Circleback MCP server, the agents and LLMs can only access a fixed set of Circleback tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Circleback 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 Circleback tools.

Yes, absolutely. You can configure which Circleback 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 Circleback data and credentials are handled as safely as possible.
