Caruon vs Electricity Maps
A side-by-side look at the Caruon and Electricity Maps MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Caruon for environment & nature work as a local process; choose Electricity Maps for environment & nature as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Caruon when
- You need dedicated capabilities in the Environment & Nature domain.
- You prefer a local stdio subprocess transport.
- You want tools like
get_intensity, get_intensity_by_date, get_generation_mix.
Choose Electricity Maps when
- You need dedicated capabilities in the Environment & Nature domain.
- You prefer a local stdio subprocess transport.
- You want tools like
electricitymaps_carbon_intensity, electricitymaps_power_breakdown, electricitymaps_carbon_forecast.

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.
Electricity Maps tools 3
electricitymaps_carbon_intensityCarbon intensity (gCO2/kWh) for a grid zone now — the live climate cost of a kWh drawn from the local grid. Pass a zone code (e.g. "US-CAL-CISO", "DE", "FR", "GB") or lat+lon. Example: electricitymaps_carbon_intensity({ zone: "DE", _apiKey: "your-key" })electricitymaps_power_breakdownPower generation mix for a zone — the latest breakdown of electricity by source (nuclear, wind, solar, hydro, coal, gas, ...) plus fossil-free and renewable percentages. Pass a zone code (e.g. "US-CAL-CISO", "DE", "FR", "GB") or lat+lon. Example: electricitymaps_power_breakdown({ zone: "FR", _apiKe…electricitymaps_carbon_forecastCarbon-intensity forecast for a zone — upcoming hourly gCO2/kWh predictions, useful for scheduling loads when the grid is cleanest. Requires a paid Electricity Maps plan. Pass a zone code (e.g. "US-CAL-CISO", "DE", "FR", "GB"). Example: electricitymaps_carbon_forecast({ zone: "GB", _apiKey: "your-k…

Frequently asked questions
Caruon is categorized under Environment & Nature and uses a local stdio subprocess. Electricity Maps belongs to Environment & Nature and uses a local stdio subprocess. Pick Caruon for environment & nature work and Electricity Maps for environment & nature.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Caruon has no declared pricing — check the project's own site. Electricity Maps has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add caruon and electricity-maps as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Caruon has a quality signal of 52/100 (Good) with 0 views, 0 installs and 0 GitHub stars. Electricity Maps has 53/100 (Good) with 1 views, 0 installs and 0 GitHub stars.
