Grid Carbon MCP serves the National Grid ESO Carbon Intensity feed for Great Britain: what the grid is emitting right now in gCO2/kWh, what is generating it by fuel, a 48-hour forecast, and an 18-region breakdown ranked cleanest to dirtiest.
cleanest_window is the tool that pays for itself. Give it a job length and it scans the forecast for the lowest-carbon slot and reports how much cleaner that is than the worst slot in the same horizon - a 78% spread in testing. Shifting a batch job, an EV charge or a data pipeline into that window is a real, measurable emissions cut.
No API key. Great Britain only, and the coverage tool says so plainly.
