Clarigrid MCP Server

Unified Python SDK for European and U.S. energy market data. Clarigrid provides a single, stable Python interface to access and normalise European and U.S. energy market data from multiple sources. All data comes back as timezone-aware pandas DataFrames with consistent column names and units. It is available as a remote MCP endpoint.

Teams that work with data science, energy and weather and want a hosted endpoint instead of running a local process. The project is written in Python.
