Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http gotfreefax https://www.gotfreefax.com/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Common questions

Is GotFreeFax safe?

It passed 1 of 1 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?

You need to fill in: Authorization

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 5 months ago.

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?

GotFreeFax MCP Server

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:

"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.

Available tools

Tool	Description	Auth
`send_free_fax`	Send a free fax (≤3 pages, 2/day/email/IP, email-confirmation required)	None

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)

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:

Authorization: Bearer <base64(account_number:pin)>

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.
