This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

Available tools 3

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

fax

get_fax_status

Read one fax by id. Status is queued, sending, delivered or failed. Does not charge.

quote

quote_fax

Price one fax to a US or Canadian number before sending it. Returns both tiers: standard and priority, in cents and in USDC atomic units. Does not send the fax and does not charge.

send

send_fax

Send a PDF to a US or Canadian fax number. Pass an https pdf_url. Pay with Authorization: Bearer and a prepaid API key, or with the x402 PAYMENT-SIGNATURE header. priority true uses the priority price and is sent before other agent faxes. A website or app fax is still sent first. If neither payment is present the call answers 402 with both prices.

FaxFair — questions

Answers built from our own checks of this server.

What can FaxFair do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_fax_status, quote_fax, 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 FaxFair working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 335 ms. The bar chart above shows every period we have measured.

Is FaxFair still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect FaxFair?

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.

Does FaxFair need an API key?

No. FaxFair completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is FaxFair?

It answers our handshake in 335 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
