Banxico MCP Server

A Model Context Protocol (MCP) server for accessing the Bank of Mexico (Banxico) SIE API to retrieve USD/MXN exchange rate data and other economic indicators.

License: MIT Python 3.10+

Features

  • Real-time Exchange Rates: Get the latest USD/MXN exchange rate from Banxico

  • Historical Data: Retrieve historical exchange rate data with customizable limits

  • Series Metadata: Access detailed information about economic data series

  • Date Range Queries: Get exchange rate data for specific date ranges

  • MCP Compatible: Works with Claude Desktop, Gemini CLI, and other MCP clients

Prerequisites

  1. Python 3.10+ installed on your system

  2. uvx (recommended) or uv package manager

  3. Banxico API Token - Get one from Banxico SIE API

Installation Methods

Option 1: Direct from GitHub (Auto-Updates) ⭐ Recommended

This method automatically gets the latest updates when you restart your MCP client:

Configuration for MCP clients:

"banxico": { "command": "uvx", "args": [ "--from", "git+https://github.com/cfocoder/banxico_mcp", "banxico-mcp-server" ], "env": { "BANXICO_API_TOKEN": "your_token_here" } }

No manual installation needed! uvx will automatically download and run the latest version.

Option 2: Download Single File (Manual Updates)

If you prefer to download the file locally:

  1. Install uvx (if not already installed):

    pip install uv

  2. Download the server file:

    curl -O https://raw.githubusercontent.com/cfocoder/banxico_mcp/main/banxico_mcp_server.py

  3. Configuration for MCP clients:

    "banxico": { "command": "uvx", "args": [ "--python", "3.12", "--from", "fastmcp", "--with", "httpx", "--", "python", "/absolute/path/to/banxico_mcp_server.py" ], "env": { "BANXICO_API_TOKEN": "your_token_here" } }

    To get updates: Re-download the file when new features are added.

Option 3: Traditional Installation

  1. Clone the repository:

    git clone https://github.com/cfocoder/banxico_mcp.git cd banxico_mcp

  2. Install dependencies:

    pip install fastmcp httpx

Testing

To test the server without an MCP client:

# Set your token export BANXICO_API_TOKEN=your_token_here # Run the server with a timeout to test startup timeout 5s python banxico_mcp_server.py && echo "Server starts successfully"

Adding New Tools

See EXTENDING.md for detailed instructions on adding new Banxico API endpoints.

Troubleshooting

Common Issues

  1. "BANXICO_API_TOKEN environment variable not set"

    • Ensure your API token is properly configured in the MCP client settings

  2. "Failed to retrieve data"

    • Check your internet connection

    • Verify your API token is valid

    • Ensure the Banxico API is accessible

  3. Server doesn't start

    • Verify Python 3.10+ is installed

    • Check that uvx or required dependencies are available

Debug Mode

Run with debug logging:

BANXICO_API_TOKEN=your_token PYTHONPATH=. python -c " import logging logging.basicConfig(level=logging.DEBUG) from banxico_mcp_server import mcp mcp.run() "
