Cradl AI is an API-first platform for AI-powered document extraction workflows. Use it to turn invoices, forms, and PDFs into structured data at scale.

11 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 Cradl AI account to Claude via Composio Connect, enabling it to extract invoice totals from uploaded PDFs, list failed Cradl AI extraction jobs, review purchase order extraction results, 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.

Connecting Cradl AI to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Cradl AI account

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

For example, ask Claude to:

  • "Extract invoice totals from uploaded PDFs"
  • "List failed Cradl AI extraction jobs"
  • "Review purchase order extraction results"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Cradl AI authorization link not work?

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

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

4. Why do Cradl AI actions fail after they worked before?

The Cradl AI connection can expire or lose permission.

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

5. How do I switch to a different Cradl AI account?

Claude can manage the Cradl AI connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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