Unmeasured means there is not enough evidence to decide. How these checks work
Start using io.github.jdhart81/agent-compute-ledger
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

Issue a content-addressed attestation for a ledger entry (verifiable green-compute / energy claim).
DiscoveredEmit an x402-C carbon receipt for a recorded work entry — the physically-grounded {version, g_co2e, energy_j, method, landauer_*, ...} object an x402 machine-payment receipt can carry. method is 'landauer-floor' when the workload declared bit_ops (thermodynamically validated), else 'measured'. Pass offset_ref (a retirement id from the offset clearinghouse) to assert carbon-neutrality. Read-only; the returned attestation_hash binds the receipt to the ledger's hash chain.
DiscoveredDescribe this agent: name, version, purpose, every action it supports and the inputs each one takes. Read-only and free; call it first to learn how to use this server.
DiscoveredAggregate footprint for an agent: total J, kWh, gCO2e, cost, and mean Landauer efficiency. Totals are exact sums of the ledger entries.
DiscoveredFetch one immutable inventory record by inventory_id.
DiscoveredThermodynamic ceiling on information processing for a power budget. Returns the Landauer ceiling P / (k_B*T*ln 2) on irreversible bit operations per second (established physics), the Intelligence Bound min(rho*B, P / (k_B*T*ln 2)) (Viridis's working conjecture), which term binds, and, if you pass a measured rate, how far your workload sits below it. Free, read-only and deterministic.
DiscoveredList all ledger entries for an agent.
DiscoveredList the separate GHG inventory chain for an agent.
DiscoveredRecord an audited GHG inventory in a separate append-only chain. mass_g is exact integer grams; content and factor-pack digests are bare lowercase SHA-256 hex. Idempotent on inventory_id.
DiscoveredRecord a unit of agent compute work. energy_j = power_w * duration_s; carbon_g follows from grid intensity. If bit_ops is declared, the entry is validated against the Landauer floor (bit_ops * kB * T * ln2) — physically impossible claims are rejected. Idempotent on entry_id.
DiscoveredVerify an attestation by recomputing the entry hash.
DiscoveredVerify the tamper-evident hash chain of an agent's ledger.
DiscoveredVerify an agent's inventory hash chain independently of compute work.
