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 HighLevel account to Claude via Composio Connect, enabling it to create opportunity for Acme Corp contact, list open opportunities for location A, send SMS reply to conversation 123, 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 HighLevel account

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

For example, ask Claude to:

  • "Create opportunity for Acme Corp contact"
  • "List open opportunities for location A"
  • "Send SMS reply to conversation 123"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the HighLevel authorization link not work?

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

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

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

The HighLevel connection can expire or lose permission.

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

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

Claude can manage the HighLevel connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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