Itzamná

Mexico's public data, ready for AI.

Itzamná is an open-source project so that any AI assistant (Claude, ChatGPT, Gemini or a local one) can query Mexico's official information and answer citing the source, instead of making numbers up.

01The idea

Ask an AI model for the peso exchange rate, September's inflation or how many businesses are in your neighborhood: it will answer confidently, even if the figure is stale or invented. Models have no access to Mexico's official sources, and that gap matters to companies, accountants, journalists and anyone making decisions with data.

The answer isn't training a new model, it's giving them tools. Each Itzamná MCP server connects AI to an official source (Banxico, INEGI, SAT…) and returns the figure with its series, cut-off date and origin, so anyone can verify it.

02How it works

  1. 01

    You

    Ask your AI assistant something about Mexico.

  2. 02

    The model

    Any of them: Claude, GPT, Gemini or a local one with Ollama.

  3. 03

    Itzamná

    The MCP server queries the right official source.

  4. 04

    The answer

    The figure with its source and cut-off date.

03Servers

04Principles

Every answer says where it comes from and how current it is.

Open source and free

MIT license, PyPI packages and public endpoints with no sign-up.

Made in Mexico

In Spanish, built for local use cases.

Why Itzamná

Itzamná was the Maya god of wisdom; tradition says he invented writing and the calendar, the way to keep a record of what is known. The logo is a stepped fret, the xicalcoliuhqui, found on temples all over Mexico.

05Where it's going

  1. MCP servers

    One for each major public data source in Mexico.

  2. The Itzamná agent

    An assistant that works with any model and always checks the official source.

  3. An open model

    Later, a model fine-tuned to use these tools, published on Hugging Face.
