Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to gotfreefax.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP server that lets an assistant send free or paid faxes to US and Canada numbers, check delivery status, and manage prepaid credits.

What you can do: Send faxes to US or Canada numbers, free (3 pages, email confirmation) or paid via a prepaid account with attached PDF, DOC, DOCX, JPG or TXT files
Check the delivery status of a sent fax by job_id and list faxes previously sent by the account
View the account's page and dollar balance
Start a prepaid credit purchase and get back a PayPal payment link
List the file formats that can be faxed
When to use it: Useful when someone wants to fax a document to a US or Canada recipient directly from a chat, either as a one-off free send with email confirmation or through a prepaid account for larger documents without the confirmation step.
Requirements: A remote MCP endpoint; no local installation. Clients that do not speak HTTP MCP natively need a bridge such as mcp-remote, which requires Node.js. Free tools need no account. Paid tools need an Authorization header with a Bearer token built from the prepaid account number and PIN. Network access to the service.

Before you install

Paid tools require the Authorization header carrying account number and PIN, so treat it as a secret. purchase_credits leads to real PayPal payments (for example 9.95 USD for 100 pages); credits are only loaded after payment. Sending a fax transmits the document and sender/recipient details to GotFreeFax. Free faxes do not send until the recipient of the confirmation email clicks the link, and the daily limit is checked at click time.

Installation

In SourceWeft

Open GotFreeFax in the dashboard and add it to a workspace.
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.gotfreefax%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

README

[GotFreeFax]

GotFreeFax MCP Server

[License: MIT] [MCP]

Send faxes to the US and Canada from Claude, ChatGPT, Codex, and other AI agents over the Model Context Protocol. No account required to start.

Endpoint: https://www.gotfreefax.com/mcp
Full docs: https://www.gotfreefax.com/mcp-server
Service homepage: https://www.gotfreefax.com

What it does

The GotFreeFax MCP Server exposes GotFreeFax.com's fax-sending capabilities as MCP tools. An AI agent can:

Send a free fax to any US/Canada number (3-page limit, 2/day per email & IP, email-confirmation required)
Send a paid fax (up to 300 pages, no confirmation step) once the user has a prepaid account
Purchase prepaid credits without leaving the chat — the tool returns a PayPal payment link
Check fax status, list sent faxes, and view account balance

The free tier means a brand-new user can complete a real workflow ("Claude, please fax this to my doctor") with no signup. Paid tiers unlock larger documents and remove the confirmation step.

Quick start (Claude Desktop, free, no account)

Add this to your claude_desktop_config.json and restart Claude Desktop:

json

{  "mcpServers": {    "gotfreefax": {      "command": "npx",      "args": ["mcp-remote", "https://www.gotfreefax.com/mcp"]    }  }}

{  "mcpServers": {    "gotfreefax": {      "command": "npx",      "args": ["mcp-remote", "https://www.gotfreefax.com/mcp"]    }  }}

Then ask Claude something like:

"Send a free fax to 555-123-4567 with the text 'Hello from Claude'."

Claude calls send_free_fax, you receive a confirmation link by email, and the fax sends once you click it.

Requires Node.js installed locally — mcp-remote bridges Claude Desktop to the remote MCP endpoint.

Client setup

Claude Desktop

No credentials (free tools only): see Quick start above, or examples/claude_desktop_config.json.

With credentials (full access): see examples/claude_desktop_config.with-auth.json.

Codex CLI (OpenAI)

Add to ~/.codex/config.toml — see examples/codex.config.toml.

ChatGPT

ChatGPT's MCP support is rolling out across surfaces. The most reliable path as of mid-2026 is the ChatGPT desktop app's connector / MCP settings; the web UI uses an OAuth-based Connectors mechanism configured in account settings (not via JSON files). The values you need:

Endpoint: https://www.gotfreefax.com/mcp
Transport: Streamable HTTP (JSON-RPC 2.0 over POST)
Authentication (for paid tools): Bearer token, format "Bearer " + base64(account_number + ":" + pin)

Follow OpenAI's current documentation for the exact UI steps.

Cursor, Windsurf, and other MCP clients

Any client that speaks MCP over HTTP can connect. Use the same JSON shape as Claude Desktop in the client's MCP settings.

Raw JSON-RPC (custom clients)

bash

curl -X POST https://www.gotfreefax.com/mcp \  -H "Content-Type: application/json" \  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

curl -X POST https://www.gotfreefax.com/mcp \  -H "Content-Type: application/json" \  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

See the Examples section of the canonical docs for full per-tool requests and responses.

Authentication

Free tools work anonymously. Authenticated tools require an Authorization header:

Where account_number and pin come from a GotFreeFax prepaid account. You can buy one through the purchase_credits tool without leaving your AI client — after PayPal payment, account credentials are emailed to you.

Rate limiting: 5 failed auth attempts per IP per 30 min; 10 per account per 30 min. Detailed PIN/auth design at the Authentication section of the docs.

Pricing

Tier	Cost	Includes
Free (`send_free_fax`)	$0	3 pages max, 2/day per email/IP, email-confirmation step
Prepaid 100 pages	$9.95	`send_fax` with no confirmation step
Prepaid 250 pages	$19.95	as above
Prepaid 800 pages	$49.95	as above
International prepaid	$49.95 / $99.95 / $199.95	dollar-balance-based, see docs

purchase_credits returns a standard PayPal payment URL; payment is processed by PayPal. GotFreeFax does not store payment instruments.

Privacy & terms

This MCP server is a thin protocol surface over the existing GotFreeFax.com service. Standard service terms apply:

Fax content, sender/recipient identifiers, and account credentials are transmitted to GotFreeFax for delivery. No fax content is logged beyond what's required for delivery and statutory record-keeping.

About this repo

This repository is the canonical project page for the GotFreeFax MCP Server, containing setup examples, an MCP manifest, and pointers to the live service. The server itself is hosted at https://www.gotfreefax.com/mcp — there is no local installation. The repo is published under the MIT License so the config snippets are free to copy into your own setups.

The server implementation is part of the GotFreeFax.com web application (closed-source).

Tools

send_fax

Send a fax to a US or Canada phone number. Accepts PDF, DOC, DOCX, JPG, JPEG, TXT files (max 10) as base64-encoded content.

Parametersfilesrequiredfax_numberrequirednotify_url

check_fax_status

Check the delivery status of a previously sent fax using its job_id. No authentication required — the job_id is the unforgeable token.

Parametersjob_idrequired

get_account_balance

Get the current page balance and dollar amount balance for the authenticated account.

Takes no parameters.

list_sent_faxes

List faxes previously sent by the authenticated account (most recent first). Includes faxes sent via MCP, REST API, and the prepaid web form. Free anonymous sends are not included.

Parameterslimitoffset

purchase_credits

Start a prepaid credit purchase. If the request is authenticated, credits will be loaded into the authenticated account after PayPal payment. If the request is not authenticated, provide email and name to create a new prepaid account (or load credits into an existing one with the same email). Returns a PayPal payment URL the user must visit to complete the purchase.

Parametersnameemailservice_typerequired

send_free_fax

Send a free fax to a US or Canada number (no account required). Limited to 3 pages total and 2 sends per email/IP per day. Returns a job_id immediately, but the fax does NOT send until the sender clicks a confirmation link emailed to sender_email. The daily-limit check happens at click time, not at submission — a submitted fax may still be rejected if the limit is hit by then; the agent can detect this by calling check_fax_status after the user reports clicking the link. If the document exceeds the free page limit, the response will suggest using purchase_credits to buy a prepaid account.
