Russian FNS Tax Calculator MCP server
by atomno-mcp
Have your AI run Russian tax and contribution calculations, plus check fiscal statuses by tax number.
This is a helper for people who deal with Russian taxes: sole traders, small businesses, and accountants. It lets your AI do common tax sums for you, like VAT, simplified tax, and sole trader contributions, and also look up public fiscal statuses. You do not need to be technical. You just ask in plain words.
What is an MCP server? The 30-second version
On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to Russian tax calculators and public fiscal checks, so it can work out numbers or look up a status for you when you ask. You do not install anything complicated; you just add it once and then talk to your AI as usual.
What this MCP server does
You ask your AI a tax question in normal words, for example how much VAT to add to an amount. The AI uses this helper to run the right calculation. The helper works out the number using the current rules and shows the formula and a link to the tax law article. For status checks, the helper asks a hosted service that reads public tax data, and then tells you what it found. You get the answer right in the chat.

What it gives back to you
You get a clear answer in the chat: the calculated number, the formula used, and a link to the relevant tax law article. For status checks, you get a short result like registered or not, plus the source. Every answer includes a disclaimer that it is not tax advice. Nothing is changed anywhere; it only reads and calculates.
Before you start
What you need
- The uvx or pipx tool installed on your computer (the README shows the one-line commands)
- An API key from Atomno MCP if you want the live status checks and always-fresh rates (the calculators work without it)
- A tax number (INN) when you want to check a status
Good to know
This is not tax advice, rates and limits change, and the live checks use public data, so always confirm important numbers with the official tax service or a professional.
