Notsy Facturación is a Model Context Protocol (MCP) server: Emite CFDIs 4.0 y resuelve claves del SAT para agentes de IA (México), con permisos por API key. In practice that means any MCP-compatible AI assistant can call Notsy Facturación's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://mcp.notsy.com.mx/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
Notsy Facturación is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
