Agent Compute Ledger tools (12)

write = sends, deletes, buys or posts
  • attestFree

    Issue a content-addressed attestation for a ledger entry (verifiable green-compute / energy claim).

  • carbon_receiptFree

    Emit 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.

  • describe_agentFree

    Fleet-standard self-description.

  • footprintFree

    Aggregate footprint for an agent: total J, kWh, gCO2e, cost, and mean Landauer efficiency. Totals are exact sums of the ledger entries.

  • get_inventoryFree

    Fetch one immutable inventory record by inventory_id.

  • list_entriesFree

    List all ledger entries for an agent.

  • list_inventoriesFree

    List the separate GHG inventory chain for an agent.

  • record_inventoryFree

    Record 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.

  • record_workFree

    Record 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.

  • verify_attestationFree

    Verify an attestation by recomputing the entry hash.

  • verify_chainFree

    Verify the tamper-evident hash chain of an agent's ledger.

  • verify_inventory_chainFree

    Verify an agent's inventory hash chain independently of compute work.

What the publisher says

From the Agent Compute Ledger repository's README, as published. We do not edit it. Read it on GitHub

Viridis Agent Fleet: open-source agents for the agent economy

Deterministic, auditable MCP agents: trust and settlement rails (identity, trust, escrow, metering, arbitration, notary, surety, provenance, covenant, offsets, compute-ledger) and priced-grade services (tax credits, GHG accounting, construction takeoff, measurement, compliance). Every core is pure Python with no LLM in the serving path, and every result is content-addressed so anyone can re-verify it.

Licensed Apache-2.0. Run any agent yourself, fork it, embed it.

Run an agent locally (free, forever)

pip install -r requirements-dev.txt
python3 agent-escrow-agent/adapters/mcp_server.py          # stdio MCP
python3 run_fleet_tests.py                                 # every agent's invariant tests

Or use the hosted fleet

https://mcp.viridisconservation.com runs all agents as one managed MCP service:

Free tier: 10 calls/day per service; the rails (identity, escrow, metering…) are free forever. Verification is always free.

Boundary

This repo contains agent cores, MCP adapters, tests, standards and self-host tooling. The hosted service layer (gateway, payment and settlement, seats, signing authority, operations, telemetry and customer data) is proprietary and is not in this repo. Please don't open PRs that add it.
