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 Engage account to Claude via Composio Connect, enabling it to send SMS to users about Black Friday deals, create and schedule a new email campaign, get analytics on last week's push notifications, 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 Engage account

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

For example, ask Claude to:

  • "Send SMS to users about Black Friday deals"
  • "Create and schedule a new email campaign"
  • "Get analytics on last week's push notifications"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Engage authorization link not work?

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

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

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

The Engage connection can expire or lose permission.

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

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

Claude can manage the Engage connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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