What this server can do

6 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

calculate_inventory(options, activities, request_id, payment_ref)
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. Required: activities.
classify_activity(activity)
Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion. Required: activity.
describe_agent
Return fleet-standard capabilities, version, pack digest, and pricing.
get_factor_pack(year, region)
Return factors, GWP values, conversions, sources, and pack SHA for one exact bundled region/year. No nearest-region or nearest-year substitution. Required: region, year.
list_factor_packs
List the bundled pack version/digest, supported regions and years, activity types, GWP set, and explicit MVP coverage.
verify_result(result_json)
Recompute a prior inventory's audit hash and conservation checks. Pass the prior result object as JSON; tampering or stale factor lineage is flagged. Required: result_json.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
