Tlaloc MCP Server

Connect Claude, ChatGPT, and any AI assistant to official Mexican data.

The Tlaloc MCP (Model Context Protocol) server gives AI assistants and agents live, authenticated access to official Mexican data sources: CURP (RENAPO), RFC (SAT), postal codes (SEPOMEX), phone numbers (IFT), and SPEI payment receipts / CEP (Banxico). Pay per call in MXN via SPEI — no credit card, no subscription.

As far as we know, this is the first MCP server for official Mexican data.

Why

• AI-native. Validate a CURP, verify an RFC, or download a SPEI CEP straight from your assistant or agent — no glue code.
• Official sources. RENAPO, SAT, SEPOMEX, IFT, Banxico.
• One key, many services. A single tlmx_ API key covers everything.
• Fair, transparent pricing. Pay per call (CURP $0.25, RFC $0.10, postal/phone $0.01, CEP $0.10 MXN). Prepaid via SPEI, no minimum, no monthly fee.

Quick start

1. Create an account and generate an API key at https://console.tlaloc.sh (keys look like tlmx_...).
2. Add the server to your MCP client:

Claude Code

claude mcp add --transport http tlaloc \
  https://api.tlaloc.sh/mx/mcp \
  --header "Authorization: Bearer tlmx_YOUR_API_KEY"

Claude Desktop / other MCP clients (JSON config)
