Banxico — Claude Code MCP server: what it does, how to install
Pulls official Mexican economic indicators directly from Banco de México. Useful for tracking real-time USD/MXN exchange rates and central bank interest figures.

This server connects AI assistants to the Banco de México SIE economic database. It registers dedicated tools to fetch dollar-to-peso exchange rates, INPC inflation statistics, UDIS values, and central bank reserves. You can also query custom indicator series with consultar_serie_sie across specific date ranges using official series identifiers.
You have two setup paths. The remote hosted endpoint at https://banxico-mcp.duckdns.org/mcp needs zero configuration and no API key, though it throttles traffic per IP address. Running the tool locally via uvx mcp-banxico bypasses shared rate limits. Local execution demands Python 3.10 and a personal token in the BANXICO_TOKEN environment variable, without which SIE requests fail.
What it helps with
- retrieve official USD/MXN exchange rates
- inspect current Mexican inflation metrics and UDIS values
- look up TIIE interbank interest benchmarks
- extract historical time series from Banxico SIE by series code
Example prompts for the agent
- Fetch the latest official USD/MXN exchange rate with
tipo_cambio_usd - What is the current 28-day TIIE interest rate in Mexico?
- Pull data for series
