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 Copper account to Claude via Composio Connect, enabling it to create a new lead from email, list open opportunities assigned to me, log a call and attach meeting notes, 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 Copper account

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

For example, ask Claude to:

  • "Create a new lead from email"
  • "List open opportunities assigned to me"
  • "Log a call and attach meeting notes"

It will prompt you to authenticate and authorize access.

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

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

The Copper MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Copper account. It provides structured and secure access to your CRM records, activities, files, pipelines, and account settings, so your agent can create leads, find contacts, track opportunities, assign tasks, and review customer activity on your behalf.

  • Lead and contact management: Have your agent create leads, people, and companies, find people by email, update records in bulk, or convert qualified leads into contacts, companies, and opportunities.
  • Opportunity and pipeline tracking: Let the agent create opportunities and review your configured pipelines, stages, and win probabilities before adding new deals.
  • Projects, tasks, and activities: Direct your agent to create projects, assign tasks with due dates and priorities, add notes or other activities, and review activity tied to leads, people, or companies.
  • CRM record organization: Instruct your agent to connect related records, apply tags and custom fields, inspect field requirements, and remove records or relationships you no longer need.
  • Files and account context: Have your agent list attached files, inspect file details, delete outdated attachments, and check the connected account or current user before assigning work.

Troubleshooting

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

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

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

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

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

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

3. Why does the Copper authorization link not work?

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

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

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

The Copper connection can expire or lose permission.

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

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

Claude can manage the Copper connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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