Api Key

CloudPDF is an API platform for creating, uploading, managing, and sharing PDF documents. Use it to build secure PDF workflows with webhooks, share links, and access control.

10 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 CloudPDF account to Claude via Composio Connect, enabling it to upload and securely share a PDF, list recent CloudPDF documents by status, create webhook for PDF upload events, 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 CloudPDF account

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

For example, ask Claude to:

  • "Upload and securely share a PDF"
  • "List recent CloudPDF documents by status"
  • "Create webhook for PDF upload events"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the CloudPDF authorization link not work?

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

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

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

The CloudPDF connection can expire or lose permission.

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

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

Claude can manage the CloudPDF connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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