Today is the operative word: we check Faxwell every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

This server publishes 1 more address. The block above uses the one we reach during checks; the full list is under Endpoints below, and the author may intend a particular one for your client.

Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

fax
fax_status
How a fax set up with send_fax is going: waiting for payment, sending, trying again, delivered, or why it didn’t go through.
send
send_fax
Send a fax to a US or Canada fax number with Faxwell (10¢ a page, no subscription, no account needed first). Give the document as base64 (PDF, PNG or JPEG), as a public https link to one, or as the plain text of a letter you wrote. This prepares the fax and returns a link for the user: they check it and pay (Apple Pay, Google Pay or card) or use page credits they already have, and it sends automatically. Nothing is sent or charged before that. If you can’t pass the file, call this with just the number: the user can add the document at the link.

Faxwell — questions

Answers built from our own checks of this server.

What can Faxwell do?
It exposes 2 tools, read directly from the server on our last check. Among them: fax_status, send_fax. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Faxwell working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 171 ms. The bar chart above shows every period we have measured.
How do I connect Faxwell?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to Faxwell?
No API key is involved. Faxwell answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is Faxwell?
It answers our handshake in 171 ms on average, which is faster than 75% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Faxwell open source?
We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
