# Faxify MCP

> Faxify MCP is a Model Context Protocol (MCP) server that lets AI assistants — ChatGPT, Claude, Cursor, and any OAuth 2.1 client — send, receive, and manage faxes through natural conversation. It bridges AI assistants to the Faxify fax service. MCP endpoint: https://mcp.faxify.com/api/v1/mcp

Faxify MCP is operated by Const Agility, LLC, the makers of Faxify (https://www.faxify.com). It connects AI assistants to a real fax backend so users can send and receive faxes to/from physical fax machines and fax numbers in the US and Canada without leaving their AI tool. Authentication is per-user (a Faxify account); the server forwards each request to the Faxify API using the user's token and stores no fax data of its own.

## What you can do with it

- Send a fax from one or more document URLs (PDF/image), with an optional cover page.
- Fax a LOCAL (on-device) file: request a short-lived signed upload URL, upload the file's bytes directly to it, then fax it by reference (no public hosting needed).
- Send a fax from a saved draft.
- List inbox (received) and sent faxes with search, filtering, and pagination.
- Check fax delivery status and resend failed faxes.
- Create, read, update, and delete drafts; preview a draft before sending.
- View subscription plans and the current account's profile and usage.

## Connecting an AI client

- Cursor / Claude Desktop (JWT): run the `@faxify/mcp-client` bridge with env `FAXIFY_MCP_URL=https://mcp.faxify.com/api/v1/mcp` and `FAXIFY_JWT_TOKEN=<token from Settings → MCP Configuration>`.
- ChatGPT and other OAuth 2.1 clients: add a connector pointing at `https://mcp.faxify.com/api/v1/mcp`; it auto-discovers OAuth endpoints and registers itself (no token to paste).
