Oh Fax is a remote MCP server that gives an AI agent 4 tools, among them get_fax_receipt, get_fax_status, quote_fax. It answers at https://app.ohfax.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 23 September 2026; the last check, on 6 November 2026, succeeded.
Outbound US/CA fax for agents: quote PDF, pay via MPP, get delivery receipt.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_fax_receipt | Verifiable delivery receipt for a completed fax. Available once the fax has reached a final state. Use this to prove the workflow finished. Inputs: fax_id |
get_fax_status | Current delivery state of a fax: awaiting_payment, paid, submitted, sending, delivered, or failed. Failed faxes include a reason you can act on. Inputs: fax_id |
quote_fax | Returns the price: $2.00 per fax by card for up to 100 pages (flat, no per-page charge); prepaid balance or MPP stablecoin: $0.02 per page. Also validates the number and PDF and returns a quote_id and payment link. Free; sends nothing. Call Inputs: to, document_url, document_base64 |
send_fax | Returns the authorization instructions for sending a previously quoted fax. THIS ACTION COSTS MONEY AND CANNOT BE UNDONE: paying the returned link transmits a real document to a real fax machine. This tool itself does not charge you — it re Inputs: quote_id |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://app.ohfax.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 21 September 2026. The tools are exactly what the server returned; nothing on this page
