Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

factor
get_factor_pack
Return factors, GWP values, conversions, sources, and pack SHA for one exact bundled region/year. No nearest-region or nearest-year substitution.
list_factor_packs
List the bundled pack version/digest, supported regions and years, activity types, GWP set, and explicit MVP coverage.
calculate
calculate_inventory
Calculate an auditable GHG inventory from explicit activity records. Returns per-line gas/CO2e results, Scope 1/2/3 and category rollups, dual Scope 2 reporting, indeterminate lines, factor lineage, notary payload, and an offset-clearinghouse dry-run weave. This is calculation, not advice. Price: $1.00 per call after 10 free calls/day. Pay at /x402/ghg-ledger/calculate_inventory with Base USDC, cash-fund payment_ref through escrow_checkout + confirm_escrow_funding, or use /seats.
classify
classify_activity
Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion.
describe
describe_agent
Return fleet-standard capabilities, version, pack digest, and pricing.
verify
verify_result
Recompute a prior inventory's audit hash and conservation checks. Pass the prior result object as JSON; tampering or stale factor lineage is flagged.

Ghg Ledger — questions

Answers built from our own checks of this server.

What can Ghg Ledger do?
It exposes 6 tools, read directly from the server on our last check. Among them: calculate_inventory, classify_activity, describe_agent, get_factor_pack, list_factor_packs, verify_result. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Ghg Ledger working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 336 ms. The bar chart above shows every period we have measured.
How do I connect Ghg Ledger?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Ghg Ledger need an API key?
No. Ghg Ledger completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Ghg Ledger?
It answers our handshake in 336 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Ghg Ledger open source?
Yes — written in Python, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
