At a Glance & Executive Verdict
Carbon Footprint Calculator
Environment & Nature · Local stdio
Quality: 39/100 (Fair) | Auth: No auth required
Caruon
Environment & Nature · Local stdio
Quality: 49/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Carbon Footprint Calculator if you need specialized Environment & Nature tools running via a local process. Choose Caruon if your workspace requires Environment & Nature integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Carbon Footprint Calculator when:
You need dedicated capabilities in the Environment & Nature domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Primary tools included: Calculates Scope 1, 2, and 3 emissions, Accepts bank, Xero, and QBO exports, Uses EPA GHG emission factors.
Check 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.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Carbon Footprint Calculator is categorized under Environment & Nature and uses a local stdio subprocess. In contrast, Caruon belongs to Environment & Nature using local stdio subprocess. Select Carbon Footprint Calculator when you need capabilities focused on environment & nature and Caruon when you require tools for environment & nature.
Get 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_mix
Check 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_intensity
Carbon 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_factors
Carbon 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.
