Why

AI assistants either make up Mexican economic figures or use stale ones, so you end up looking them up by hand at Banxico, INEGI or the SAT and pasting them in. mcp-mexico lets any MCP client (Claude Desktop, Claude Code, Cursor) fetch them directly. Every result names its official source and the date it applies to.

Tools

getuma and getisr_table work offline with no configuration. Their data ships inside the package; each table cites the document it was taken from and the date it was verified.

The bundled UMA covers up to 2026. From 1 February 2027, get_uma returns an error until the package is updated, instead of a stale value.

Get your tokens

Both are free and take a couple of minutes.

1. Banxico: open the SIE API token page, solve the captcha and click "Generar token". The 64-character token appears on the page.
2. INEGI: enter your email in the INEGI token form. The token arrives by email.

You can start with only one token, or none: tools whose token is missing return a message explaining how to get it.

Install

You need uv. The server runs with uvx mcp-mexico; you don't start it yourself, your MCP client does.

Claude Code

claude mcp add mcp-mexico -e BANXICO_TOKEN=your-token -e INEGI_TOKEN=your-token -- uvx mcp-mexico

Claude Desktop

Add this to claudedesktopconfig.json (Settings → Developer → Edit Config) and restart Claude Desktop:

{
  "mcpServers": {
    "mcp-mexico": {
      "command": "uvx",
      "args": ["mcp-mexico"],
      "env": {
        "BANXICO_TOKEN": "your-token",
        "INEGI_TOKEN": "your-token"
      }
    }
  }
}

Cursor

Add the same mcpServers block to ~/.cursor/mcp.json.
