mcp-fns-calc

Overview

mcp-fns-calc is a Model Context Protocol server that brings Russian tax calculation and fiscal-status verification into your AI workflow. It provides tools for VAT, USN, and NDFL tax calculations alongside FNS fiscal-status checks, letting any MCP-compatible AI assistant call these functions directly during conversation or agent tasks.

The server runs locally as a Python package. Install it via uvx atomno-mcp-fns-calc on your machine, where it communicates over stdio with your MCP client. You'll need an API key for authentication. The latest release is v0.1.4, published under the MIT license with source code available at atomno-mcp/mcp-fns-calc on GitHub.

mcp-fns-calc is categorized under Finance and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this server, claim your listing on mcp.site to verify ownership and keep information up to date.
