GotFreeFax tools (7, 3 write)

write = sends, deletes, buys or posts
  • check_fax_statusFree

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

  • get_account_balanceFree

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

  • list_sent_faxesFree

    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.

  • list_supported_formatsFree

    List all supported file formats that can be faxed.

  • purchase_creditswrite actionFree

    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.

  • send_faxwrite actionFree

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

  • send_free_faxwrite actionFree

    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.

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:
  • Service homepage:

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 claudedesktopconfig.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 sendfreefax, 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

See the full documentation for per-tool parameter schemas and response shapes.

Client setup

Claude Desktop

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

With credentials (full access): see examples/claudedesktopconfig.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)

Shortened. The full README is on GitHub.
