What it can do

get_test_numbers
Get the Faxbeep test fax numbers, the test email addresses and the limits. Call this first, before the person sends a test. Each item of "numbers" is a test fax number: "local_format" is the number to dial inside its country, "international_format" from any other country. The per
list_test_faxes
List the test faxes that Faxbeep received and published, newest first. The list is public and holds the tests of everyone. Each item of "faxes" is a fax object: slug, source ("phone" or "email"), from (the sender, masked as on faxbeep.com, or null), received_at, page_count, file_
get_test_fax
Get one test fax by its slug (fax_ and 8 characters from 0-9 and a-f, for example fax_1a2b3c4d) or by the URL of its page on faxbeep.com (view_url, with or without a language prefix such as /de). The result is the fax object, the same as an item of list_test_faxes, and after it a

Common questions

Is Faxbeep safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

Faxbeep MCP server

Test a fax machine, a fax service or a scan-to-email setup from your AI agent. Faxbeep gives free public test fax numbers and test email addresses. Send a test to one, then ask your agent whether it arrived.

https://faxbeep.com/mcp

Remote server, Streamable HTTP, no authentication. Read-only.

Every test that Faxbeep receives is public on faxbeep.com for 30 days. Do not send a private document.

Add it to your chat app

Claude: Customize > Connectors > Add custom connector. Name Faxbeep, URL https://faxbeep.com/mcp, no sign in.
ChatGPT: turn on developer mode in the Apps settings, then create an app with the URL https://faxbeep.com/mcp and no authentication.

Menus change often. The docs have the current steps.

Add it to a coding agent

# Claude Code

claude mcp add --transport http faxbeep https://faxbeep.com/mcp

Codex

codex mcp add faxbeep --url https://faxbeep.com/mcp

Cursor: put this in ~/.cursor/mcp.json, or in .cursor/mcp.json in a project:

"mcpServers": { "faxbeep": { "url": "https://faxbeep.com/mcp" } } }

Add it to Gemini CLI

Install the extension from this repository:

gemini extensions install https://github.com/faxbeep/faxbeep-mcp --ref main

Use /mcp to check the connection and see the three tools. The --ref main is needed: without it, the installer takes a release, and a release holds only the ChatGPT package.

Add it to Antigravity

The Antigravity plugin package connects to the hosted server. See its installation instructions.

Tools

Tool	What it does
`get_test_numbers`	The test fax numbers (US, UK, Australia), the test email addresses, the limits, and `now`, the server time
`list_test_faxes`	The test faxes received since a time, newest first. Filters: sender, page count, limit
`get_test_fax`	One test fax, by its slug (`fax_1a2b3c4d`) or by the URL of its page on faxbeep.com

Each result gives the sender (masked as on faxbeep.com), the time received, the page count, and links to the PDF, the thumbnail and the page of the fax.

A match by time, sender or page count narrows the candidates. It does not prove that a fax is yours, because other people send tests at the same time. Check the page.

Example

I want to test the fax machine at the office. Give me a number, and tell me when my fax arrives.

The agent calls get_test_numbers, gives you a number, and notes the server time. You send the fax. The agent calls list_test_faxes with that time and shows you the page of each new fax, so you can find yours.

To try the connection without sending anything, ask for the fax fax_example. It is a fixed sample, not a real fax.

Faxbeep does not send faxes

Faxbeep only receives. To send a test without a fax machine, use a fax sending service, for example PayPerFax, which has its own MCP server.

About this repository

This repository documents the hosted server. The server code is not open source. server.json is the entry in the official MCP registry as com.faxbeep/faxbeep. Its version counts the versions of that registry entry. It is not the version that the server reports.

The files in this public repository are available under the MIT License. That license does not cover the hosted server, which is not included here.
