PayPerFax — Claude Code MCP server: faxing and setup
PayPerFax lets an AI agent prepare a fax and create a browser link for review and payment. Use it to send a drafted letter or attach a file yourself.
claude mcp add --transport http fax https://fax.payperfax.com/mcpWhat PayPerFax does
The server exposes three tools. create_fax prepares a fax and returns a link, get_fax_status reports its state, and list_supported_formats shows accepted file types, size limits, and languages. An agent can turn a letter into Markdown; if you have a finished document, upload it through the form opened by the link.
Payment happens in your browser after you inspect the preview. The agent does not pay, and no account or API key is needed. MCP cannot move chat attachments to the server, so you must add a PDF or scan in the browser. Failed transmissions are not charged. Check the fax number before paying, since a typo could send your documents to the wrong recipient.
What it helps with
- prepare a fax from a drafted letter
- create a review and payment link
- check a fax transmission status
- find accepted file types and size limits
Example prompts for the agent
- Prepare a fax from this letter and give me the review link.
- Create a fax form for this number so I can attach my PDF.
- Check the status of my fax.
