Overview

AI-generated overview

Lets an assistant send a fax by uploading a PDF, paying, and checking delivery status.

What you can do
SingleFax is a remote MCP endpoint that lets an assistant send a fax directly from chat clients such as Claude, ChatGPT, or Cursor. Based on the description, the workflow covers uploading a PDF, making a payment, and retrieving delivery status for the fax.
When to use it
Useful when you need to send a document by fax to a recipient that only accepts fax, and you want to do it from within an AI assistant instead of a separate fax service or machine.
Requirements
A remote MCP endpoint at singlefax.com over streamable HTTP; no packages, environment variables, or headers are declared. A payment method is implied by the described pay step.
Before you install
The description mentions paying as part of sending a fax, so expect a charge for each send. Faxes transmit the document to a third party, so avoid sending sensitive content unless you accept that exposure.

Installation

In SourceWeft

  1. Open SingleFax in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.singlefax%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
