How Atomic Agent connects to Pdf4me

Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.

Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

Connect Pdf4me to Atomic Agent

  1. Sign up or sign in to the Composio dashboard. Copy your API key.
  2. In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
  3. Ask Atomic Agent to do something in Pdf4me. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your Pdf4me account, then return to Atomic Agent to continue.

Headless setup

Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY

What is the Pdf4me MCP server, and what's possible with it?

The Pdf4me MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Pdf4me account. It provides structured and secure access to document conversion, letting your agent automate tasks like transforming files, generating PDFs, and preparing documents for further processing—all without manual intervention.

  • Seamless document-to-PDF conversion: Instantly convert a wide variety of document and image formats to high-quality PDFs using natural language commands.
  • Batch processing automation: Let your agent handle multiple file conversions at once, streamlining workflows for reports, forms, and scanned images.
  • Workflow integration: Enable your agent to convert documents to PDF as part of larger automation chains, making it easy to prep files for storage, sharing, or e-signatures.
  • Base64 file transformation: Accept base64-encoded files from other sources and have your agent convert them to PDFs, ready for further use or archiving.

Use Pdf4me from Atomic Agent

With your account connected, ask Atomic Agent to work with Pdf4me in natural language. You can connect more apps through the same Composio integration as you need them.

Troubleshooting

Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See Composio pricing for the current limits that apply to your connection.

FAQ

Frequently asked questions

With a standalone Pdf4me MCP server, the agents and LLMs can only access a fixed set of Pdf4me tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Pdf4me and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Atomic Agent 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 Pdf4me tools.

Yes, absolutely. You can configure which Pdf4me 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 Pdf4me data and credentials are handled as safely as possible.
