Give your AI assistant the power to send and receive faxes
Faxify's Model Context Protocol (MCP) server lets ChatGPT, Claude, and Cursor send, track, and — with a dedicated fax number — receive real faxes. The server is included free on every Faxify plan, with a 10-minute setup. No enterprise tier required.
Watch: send a fax from your AI assistant
Send and receive faxes
Ask Claude, ChatGPT, or Cursor to send a fax — or, with a dedicated fax number, list and read the faxes you've received. 18 typed tools, no glue code.
Free on every plan
Faxify MCP is included on every plan, free and paid. It is not gated behind an enterprise tier or a waitlist.
10-minute setup
Point your MCP client at one URL, sign in with the same login as the apps, and you're sending faxes.
One endpoint, two auth flows
https://mcp.faxify.com/api/v1/mcpOAuth 2.1 for HTTP clients, JWT for stdio clients — the same Apple, Google, and email sign-in you already use for the Faxify apps.
18 typed tools across 4 categories
Your AI assistant discovers these automatically and chains them into multi-step workflows — outbound and inbound.
Faxes
send, list & read inbound, check status, resend, delete
Drafts
create, update, preview, send a saved draft
Account
profile, fax number, usage
Subscription

Why Faxify MCP
Faxify shipped the first hosted commercial fax MCP server in November 2025. But the reason to pick it today is simpler: it's the only one included free on every plan, and the fastest to set up. Here's the honest comparison — we'll tell you where a competitor wins, too.
| Faxify MCP | Fax.Plus MCP | |

| Setup | ~10 min, self-serve | Enterprise onboarding |
| First shipped | Nov 2025 | May 2026 |

Compliance
Faxify routes faxes through SignalWire's HIPAA-eligible carrier infrastructure with BAA coverage and stores documents on Google Cloud under Google's BAA. Faxify itself is not a HIPAA-covered entity, and no published plan ships with a BAA — if you transmit PHI you remain responsible for your own compliance posture and any required Business Associate Agreements. Service coverage is the USA and Canada.
Frequently asked questions

- It is included on every Faxify plan — free and paid — at no extra cost. The free plan gives you 25 fax pages a month with no credit card.
