Weather MCPEnvironment & Nature · Local subprocess (stdio)Free, open-source MCP server giving AI assistants 17 weather tools — a one-call weather summary plus forecasts, alerts, air quality, marine, radar, lightning, rivers, wildfires, and historical data back to 1940. Ask by city name or coordinates. Built on free public APIs (NOAA, Open-Meteo). No API keys, no signup.67GreatAuth: no auth requiredVerdict: choose Caruon for environment & nature work as a local process; choose Weather MCP for environment & nature as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities
Caruon tools 5
get_intensityCheck current UK electricity carbon intensity. Returns gCO2/kWh (forecast and actual) plus intensity level (very low to very high). Use to schedule energy-intensive tasks during low-carbon periods.get_intensity_by_dateGet UK electricity carbon intensity for every 30-minute period on a specific date (e.g., "2024-01-15"). Returns gCO2/kWh forecast and actual. Use to identify lowest-carbon hours.get_generation_mixCheck current UK electricity grid composition by source percentage (gas, coal, wind, solar, nuclear, hydro, biomass, imports). Use to understand real-time grid energy mix.get_regional_intensityCarbon intensity (forecast gCO2/kWh + index band) and generation mix for a specific Great Britain region. Pass "postcode" (UK outcode — first half of a postcode, e.g. "RG10") or "regionid" (1–17, e.g. 13 = London). Omit both for all regions at the current half-hour. Regional figures are forecast-on…get_intensity_factorsCarbon intensity factors (gCO2/kWh) per fuel type used in the headline figures — e.g. Coal 937, Gas (Combined Cycle) 394, Nuclear 0, Wind 0, Solar 0.
