Api Key

Hex is a collaborative data workspace for SQL, Python, and R notebooks. It helps teams build analytics, data apps, and data science workflows together.

32 Tools

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 Hex account to Claude via Composio Connect, enabling it to list recent Hex analytics projects, run weekly revenue Hex project, check latest Hex project status, 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 Hex account

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

For example, ask Claude to:

  • "List recent Hex analytics projects"
  • "Run weekly revenue Hex project"
  • "Check latest Hex project status"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Hex authorization link not work?

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

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

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

The Hex connection can expire or lose permission.

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

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

Claude can manage the Hex connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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