Mexican Payroll & Tax Calculator is a Model Context Protocol (MCP) server: Deterministic Mexican payroll & tax math: finiquito, ISR, aguinaldo, IMSS (2026 tables). In practice that means any MCP-compatible AI assistant can call Mexican Payroll & Tax Calculator'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://fiscal.tinyapis.dev/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
Mexican Payroll & Tax Calculator is listed under Development 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.
