Pulled straight from the server with tools/list on 2026-10-17.

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_inventor

classify_activity

Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion.

list_factor_packs

List the bundled pack version/digest, supported regions and years, activity types, GWP set, and explicit MVP coverage.

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.

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.

describe_agent

Return fleet-standard capabilities, version, pack digest, and pricing.
