Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tool inventory
Tools (6)
🟢calculate_inventory(activities, options, payment_ref, request_id)
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_activity(activity)
Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion.

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.
