概覽

AI 產生的概覽

Faxbeep 提供免費的公開測試傳真號碼與測試電子郵件地址,並讓助理列出與讀取 Faxbeep 收到的測試傳真。

可以做什麼
  • 取得測試傳真號碼(美國、英國、澳洲)、測試電子郵件地址、限制與伺服器時間
  • 依指定時間列出之後收到的測試傳真,最新在前,可依寄件者與頁數篩選
  • 依 slug 或頁面網址讀取一份測試傳真,包含第一頁影像以及 PDF 與頁面連結
  • 回傳固定的範例傳真,方便在不寄送任何內容的情況下測試連線
適用情境
適合需要確認傳真機、傳真服務或掃描寄送電子郵件設定是否正常運作時使用,讓助理判斷測試是否送達並顯示收到的頁面。
執行需求
遠端 Streamable HTTP 端點 faxbeep.com/mcp,無需驗證、API 金鑰或本機套件。由於 Faxbeep 只接收不發送,使用者仍需傳真機或傳真發送服務來送出測試。
安裝前請注意
每份收到的測試都會在 faxbeep.com 公開 30 天,包含其頁面,因此不要寄送私人文件。依時間、寄件者或頁數比對只能縮小範圍,無法證明傳真屬於本人,因為同一時間還有其他人送出測試;應查看頁面確認。此伺服器為唯讀,不發送傳真。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Faxbeep,將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable,透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

README

Faxbeep MCP server

[Faxbeep MCP connector - tool definition quality and endpoint health on Glama]

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

sh
# Claude Codeclaude mcp add --transport http faxbeep https://faxbeep.com/mcp
# Codexcodex mcp add faxbeep --url https://faxbeep.com/mcp

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

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

Add it to Gemini CLI

Install the extension from this repository:

sh
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

ToolWhat it does
get_test_numbersThe test fax numbers (US, UK, Australia), the test email addresses, the limits, and now, the server time
list_test_faxesThe test faxes received since a time, newest first. Filters: sender, page count, limit
get_test_faxOne 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.

Documentation

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.

get_test_numbers

Get the 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 person sends a fax to it from a fax machine or a fax service. Each item of "email_addresses" takes an email with one PDF, TIFF or JPEG attachment, for a scan-to-email or Internet fax test. "email_addresses" is left out while the email test is off. Every test that Faxbeep receives is public on faxbeep.com for 30 days. Tell the person not to send a private document. "limits" has the limits of the email test: "email_max_message_bytes" is the size of the whole email, and email encoding adds about a third, so the attachment can be about three quarters of it. "troubleshooting_url" is the docs page with each refusal message of the email test and its fix. "now" is the server time. Use it as "since" of list_test_faxes: call this tool, or take "now" from your last result, just before the person sends the test. Do not use your own clock.

無需輸入參數。

list_test_faxes

List received 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_size, pdf_url, thumbnail_url and view_url (the page of the fax on faxbeep.com). In the result, "since" is the start time that was used, and "now" is the server time. The result holds at most "limit" faxes (20 when not given), newest first, with no paging. When "faxes" has "limit" items, there can be more: narrow the list with from, page_count or a since closer to the test. Set "since" to the "now" value that get_test_numbers or list_test_faxes returned just before the person sent the test, and keep it fixed while you poll. Do not use your own clock. Do not move since to the newest received_at: a long fax can appear after a newer, shorter one. Without "since", the list covers the last 24 hours. A match by time, sender or page count narrows the candidates. It does not prove that a fax is the person's, because other people send tests at the same time. Show the person the view_url so they can check the page. In a chat that shows images, also show thumbnail_url as an image in your answer. An empty list is a normal answer while a fax is on its way. A new fax usually appears within a minute after the call ends or the email is sent; a few take longer. Wait about 30 seconds between calls, and stop after about 10 minutes. A fax is public for 30 days, then it is removed. For a sample answer, set from to FAXBEEP-EXAMPLE: the result is the sample fax fax_example, whatever since says. The sample has a fixed date in the past, older than 30 days, and it stays available.

輸入參數fromlimitsincepage_count

get_test_fax

Get a 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 an image of page 1 when one can be read. A client can draw that image very small. In a chat that shows images, also show thumbnail_url as an image in your answer. Give view_url for the full page. A fax that is not found gives an error result: a new fax can take a while to appear, and a fax that is still processing is not found yet. A fax that was removed, by request or after 30 days, gives the error result "This fax was removed, or it is older than 30 days." Its files are deleted, so it cannot be read again. For a sample answer, use fax_example (a published sample fax) or fax_example_removed (the answer for a removed fax).
