API Reference

Important Notes

Async Generation: generate_document polls every 1.5 seconds for up to 3 minutes
Download URLs: Expire after 1 hour
Share Links: Permanent URLs for premium users
Rate Limiting: 60 requests/minute

Full API documentation: docs.pdfmonkey.io

Troubleshooting

"PDFMONKEY_API_KEY environment variable is required"

Verify your configuration file includes the API key.

"Invalid API key" or 401 errors

Get a new key from dashboard.pdfmonkey.io.

Document generation timeout

Generation took >3 minutes. Use get_document_status with the document ID to check later.

Docker container exits immediately

Ensure you're using -i (interactive) flag:

docker run -i --rm -e PDFMONKEY_API_KEY="key" pdfmonkey-mcp-server:latest
