ictfax-mcp

A Model Context Protocol server for ICTFax, the open-source fax server built on the ICTCore framework by ICT Innovations.

It lets an AI assistant list fax transmissions and check their status, and — only when you turn writes on — upload a document and send a fax.

Install

npx -y ictfax-mcp      # no install
npm install -g ictfax-mcp

Requires Node.js 18 or newer.

Tools

Read tools are always available:

| Tool | What it does | |------|--------------| | ictfax_list_faxes | List fax transmissions (id, contact, status, direction) | | ictfax_get_fax_status | Status of one transmission by id |

Write tools appear only when ICTFAX_MCP_ALLOW_WRITE=true:

| Tool | What it does | |------|--------------| | ictfax_upload_document | Upload a local PDF as a fax document; returns a document_id | | ictfax_send_fax | Send a local document as a fax to a number — dials a real number |

Safety

The server is read-only by default. Sending a fax dials a real number and can cost money, so ictfax_upload_document and ictfax_send_fax are not registered at all unless you set ICTFAX_MCP_ALLOW_WRITE=true.

How it connects

ICTFax runs on ICTCore, which authenticates with a JWT from POST /authenticate (login by email) and reads it back from the Authorization: Bearer header. Sending a fax is a short chain the server handles for you: upload the document (metadata then raw bytes, which ICTFax converts to fax format), create the recipient and a sendfax program, create the transmission and send it.
