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 Conversion tools account to Claude via Composio Connect, enabling it to convert your Excel file to clean CSV, export a website as a PDF snapshot, extract text from this Word document, 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 Conversion tools account

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

For example, ask Claude to:

  • "Convert your Excel file to clean CSV"
  • "Export a website as a PDF snapshot"
  • "Extract text from this Word document"

It will prompt you to authenticate and authorize access.

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

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

The Conversion tools MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Conversion tools account. It provides structured and secure access to a wide range of file and document conversion utilities, so your agent can convert documents, extract data, generate snapshots, and automate file handling between multiple formats on your behalf.

  • Seamless document format conversion: Effortlessly have your agent convert Excel, Word, Markdown, OXPS, or JPG files to formats like CSV, HTML, PDF, text, or JSON.
  • Website snapshot creation: Ask your agent to capture entire web pages as PDF documents or PNG images, ready to download or share.
  • Automated file upload and processing: Let your agent upload local files, obtain conversion-ready file IDs, and initiate multi-step conversion workflows.
  • AI-powered data extraction: Use AI tools to transform images (JPG) into structured JSON, streamlining data entry and analysis tasks.
  • Easy retrieval of conversion results: Direct your agent to track conversion tasks and download the final output files once processing is complete.

Troubleshooting

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

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

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

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

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

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

3. Why does the Conversion tools authorization link not work?

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

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

4. Why do Conversion tools actions fail after they worked before?

The Conversion tools connection can expire or lose permission.

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

5. How do I switch to a different Conversion tools account?

Claude can manage the Conversion tools connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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