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 Convertapi account to Claude via Composio Connect, enabling it to convert PDF invoice to editable DOCX, turn PDF presentation into JPG images, list all formats convertible to XLSX, 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 Convertapi 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 Convertapi account

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

For example, ask Claude to:

  • "Convert PDF invoice to editable DOCX"
  • "Turn PDF presentation into JPG images"
  • "List all formats convertible to XLSX"

It will prompt you to authenticate and authorize access.

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

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

The Convertapi MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Convertapi account. It provides structured and secure access to file conversion and management tools, so your agent can perform actions like converting documents, uploading files, retrieving converted outputs, and managing temporary file storage on your behalf.

  • Multi-format file conversion: Instantly convert documents, images, and spreadsheets between formats like PDF, DOCX, and JPG with just a prompt.
  • Bulk and asynchronous processing: Use asynchronous conversion for large files or batch jobs, allowing your agent to handle long-running tasks without delays.
  • File upload and remote import: Upload files directly or import them from remote URLs, making it easy to work with files stored anywhere on the web.
  • Download and manage uploaded files: Retrieve converted outputs, download original or processed files, or delete unused uploads from temporary storage.
  • Format compatibility discovery: Ask your agent to list which formats can be converted to a desired output, ensuring smooth workflow automation.

Troubleshooting

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

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

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

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

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

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

3. Why does the Convertapi authorization link not work?

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

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

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

The Convertapi connection can expire or lose permission.

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

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

Claude can manage the Convertapi connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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