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 Customgpt account to Claude via Composio Connect, enabling it to list all your active CustomGPT projects, show chat history from your latest conversation, get usage limits for your account, 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 Customgpt account

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

For example, ask Claude to:

  • "List all your active CustomGPT projects"
  • "Show chat history from your latest conversation"
  • "Get usage limits for your account"

It will prompt you to authenticate and authorize access.

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

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

The Customgpt MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your CustomGPT.ai account. It provides structured and secure access to your chatbot projects, so your agent can list, manage, update, and analyze your AI-powered chatbots and their licenses on your behalf.

  • Project and agent management: Effortlessly list all your CustomGPT projects, retrieve their details, and even delete agents you no longer need.
  • Comprehensive license handling: Let your agent fetch, update, or remove licenses attached to any of your chatbot projects, ensuring you always have the right access and compliance.
  • Chat conversation insights: Retrieve complete chat histories from your AI chatbot conversations to analyze user interactions or debug sessions.
  • User profile and usage monitoring: Automatically fetch your account profile and check on your usage limits, including agents, words, and queries, so you never exceed your quotas.
  • Project settings inspection: Quickly pull and review configuration details for any chatbot project to audit or adjust your bot's setup.

Troubleshooting

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

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

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

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

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

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

3. Why does the Customgpt authorization link not work?

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

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

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

The Customgpt connection can expire or lose permission.

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

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

Claude can manage the Customgpt connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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