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 Heyreach account to Claude via Composio Connect, enabling it to list all active outreach campaigns, get all leads from your main list, fetch LinkedIn accounts connected to HeyReach, 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 Heyreach account

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

For example, ask Claude to:

  • "List all active outreach campaigns"
  • "Get all leads from your main list"
  • "Fetch LinkedIn accounts connected to HeyReach"

It will prompt you to authenticate and authorize access.

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

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

The Heyreach MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Heyreach account. It provides structured and secure access to your outreach platform, so your agent can perform actions like managing campaigns, handling leads, creating lists, and automating webhooks on your behalf.

  • Campaign management and reporting: Retrieve and review all your active, scheduled, or past campaigns, enabling your agent to keep your outreach strategy organized and up to date.
  • Lead and list operations: Fetch all leads from any list, create new empty lists, and get a full overview of your audience segments—making bulk actions and lead tracking a breeze.
  • Webhook automation: Set up or delete webhooks programmatically, so your agent can automate notifications and integrate Heyreach data with other tools without manual effort.
  • LinkedIn account integration: Access and manage all connected LinkedIn accounts, streamlining multi-channel outreach and coordination directly from your AI assistant.
  • Company and data retrieval: Pull companies from specific lists and get detailed records, helping your agent power richer, more personalized engagement workflows.

Troubleshooting

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

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

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

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

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

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

3. Why does the Heyreach authorization link not work?

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

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

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

The Heyreach connection can expire or lose permission.

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

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

Claude can manage the Heyreach connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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