Overview

Description from the maker (original English)

Freemática ERP: invoicing, receivables, suppliers, accounting and HR through 300+ MCP tools

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Accounting, finance & tax
  • You need to fill in: FREEMATICA_AUTH_TOKEN, FREEMATICA_AUTH_COMPANY, FREEMATICA_AUTH_ORGANIZATION, FREEMATICA_AUTH_APP, FREEMATICA_AUTH_SESSION

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: FREEMATICA_AUTH_TOKEN, FREEMATICA_AUTH_COMPANY, FREEMATICA_AUTH_ORGANIZATION, FREEMATICA_AUTH_APP, FREEMATICA_AUTH_SESSION, FREEMATICA_ENABLE_WRITES, FREEMATICA_BASE_URL

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "freematica": {
      "command": "npx",
      "args": [
        "-y",
        "@nubiia/mcp-freematica"
      ],
      "env": {
        "FREEMATICA_AUTH_TOKEN": "your-value",
        "FREEMATICA_AUTH_COMPANY": "your-value",
        "FREEMATICA_AUTH_ORGANIZATION": "your-value",
        "FREEMATICA_AUTH_APP": "your-value",
        "FREEMATICA_AUTH_SESSION": "your-value",
        "FREEMATICA_ENABLE_WRITES": "your-value",
        "FREEMATICA_BASE_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add freematica --env FREEMATICA_AUTH_TOKEN=your-value --env FREEMATICA_AUTH_COMPANY=your-value --env FREEMATICA_AUTH_ORGANIZATION=your-value --env FREEMATICA_AUTH_APP=your-value --env FREEMATICA_AUTH_SESSION=your-value --env FREEMATICA_ENABLE_WRITES=your-value --env FREEMATICA_BASE_URL=your-value -- npx -y @nubiia/mcp-freematica

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "freematica": {
      "command": "npx",
      "args": [
        "-y",
        "@nubiia/mcp-freematica"
      ],
      "env": {
        "FREEMATICA_AUTH_TOKEN": "your-value",
        "FREEMATICA_AUTH_COMPANY": "your-value",
        "FREEMATICA_AUTH_ORGANIZATION": "your-value",
        "FREEMATICA_AUTH_APP": "your-value",
        "FREEMATICA_AUTH_SESSION": "your-value",
        "FREEMATICA_ENABLE_WRITES": "your-value",
        "FREEMATICA_BASE_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "freematica": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@nubiia/mcp-freematica"
      ],
      "env": {
        "FREEMATICA_AUTH_TOKEN": "your-value",
        "FREEMATICA_AUTH_COMPANY": "your-value",
        "FREEMATICA_AUTH_ORGANIZATION": "your-value",
        "FREEMATICA_AUTH_APP": "your-value",
        "FREEMATICA_AUTH_SESSION": "your-value",
        "FREEMATICA_ENABLE_WRITES": "your-value",
        "FREEMATICA_BASE_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is MCP Freematica safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: FREEMATICA_AUTH_TOKEN, FREEMATICA_AUTH_COMPANY, FREEMATICA_AUTH_ORGANIZATION, FREEMATICA_AUTH_APP, FREEMATICA_AUTH_SESSION

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.11.2) reached the registry 15 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?
