About ictfax-mcp
ictfax-mcp is an MCP server for viewing ICTFax transmissions and, when write access is explicitly enabled, uploading documents and sending faxes. It is intended for AI assistants connected to ICTFax through ICTCore REST.
Key features
- 01List fax transmissions
- 02Check a transmission’s status
- 03Upload PDF documents when writes are enabled
- 04Send faxes when writes are enabled
Use cases
- 01Review recent fax transmissions
- 02Check whether a fax was sent successfully
- 03Upload a PDF and fax it after enabling writes
MCP support
Exposes fax listing and status tools to MCP clients. Document upload and fax sending tools are registered only when ICTFAX_MCP_ALLOW_WRITE=true.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
npx -y ictfax-mcpICTFAX_BASE_URLICTCore REST base URL of your ICTFax server, normally ending in /api, e.g. https://your-ictfax/api.ICTFAX_USERNAMEAPI account email (ICTCore logs in by email).ICTFAX_PASSWORDSecretPassword for the account.ICTFAX_ACCOUNT_IDAccount id to send faxes from. Defaults to 1.ICTFAX_MCP_ALLOW_WRITEUnlocks uploading documents and sending faxes, which dials a real number and can cost money. When false those tools are not registered at all. Leave off unless you mean it.ICTFAX_TIMEOUT_MSPer request timeout in milliseconds. Defaults to 30000.ICTFAX_TLS_INSECURESkip TLS certificate verification. Only for a self-signed test server.Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details
From the project READMEictfax-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.
Configure
| Variable | Required | Default | |
|---|---|---|---|
ICTFAX_BASE_URL | yes | ICTCore REST base, normally ending in /api, e.g. https://your-ictfax/api | |
ICTFAX_USERNAME | yes | API account email (ICTCore logs in by email) | |
ICTFAX_PASSWORD | yes | Password for that account | |
ICTFAX_ACCOUNT_ID | no | 1 | Account id to send faxes from |
ICTFAX_MCP_ALLOW_WRITE | no | false | Unlock upload/send (see Safety) |
ICTFAX_TIMEOUT_MS | no | 30000 | Per-request timeout |
ICTFAX_TLS_INSECURE | no | false | Skip TLS verification — self-signed test servers only |

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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
