# Impôts France MCP

Adrien Murillo — Murillo Consulting

A French tax MCP with a Rust/Wasm engine and versioned official rules.

Demonstrates an approach where results, data versions, sources and assumptions remain auditable behind a protected MCP interface.

## Architecture
MCP client → OAuth → Worker → Rust / Wasm engine

62 sourced tools, deterministic calculations, a dated registry, Cloudflare OAuth and reference functional tests.

Public CI checks the server, engine and versioned reference cases.

No shared endpoint is guaranteed and outputs remain simulations, not tax advice.
