Faxwell MCP server

Send a fax from Claude, ChatGPT, Cursor or any app that supports MCP servers over HTTP. Faxwell faxes any US or Canada number, as low as 6¢ a page, with no subscription.

This repository holds Faxwell's entry in the official MCP Registry (com.sendfaxwell/faxwell). The servers themselves are hosted by Faxwell; there is nothing to install.

Two ways to connect

Address	Sign-in	How it sends
https://api.sendfaxwell.com/mcp	None	The AI prepares the fax and gives you a link. You check it and pay there (or use page credits you have), and it sends.
https://api.sendfaxwell.com/mcp/account	Once, in your browser (OAuth 2.1)	Sends right away from your Faxwell page credits. Disconnect any time on Your faxes.

In Claude, add a custom connector with either address. In Claude Code:

claude mcp add --transport http faxwell https://api.sendfaxwell.com/mcp

Tools

/mcp

• send_fax: a fax number, plus a PDF, PNG or JPEG (base64 or an https link) or the text of a letter. Returns the link to check and pay.
• fax_status: how a fax is going, by the code send_fax returned.

/mcp/account

• send_fax: a fax number and a document, optionally encrypted. Sends from page credits; if there aren't enough, returns a link to buy more.
• fax_status, recent_faxes, cancel_fax, account (page credits left and plan).

Every tool carries read-only and destructive hints. The signed-in server can't buy page credits or open faxes you receive.

Prices

10¢ a page, as low as 6¢ with the 200 pack. Faxwell only charges for faxes that go through. See sendfaxwell.com and the guide to faxing with AI.
