Agent Compute Ledger is an MCP server with 12 tools an agent can call, among them attest, carbon_receipt, describe_agent. It answers at https://mcp.viridisconservation.com/compute-ledger/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Compute-is-carbon energy/carbon ledger for agent work with Landauer-limit validation.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
attest | Issue a content-addressed attestation for a ledger entry (verifiable green-compute / energy claim). Inputs: entry_id |
carbon_receipt | 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 b Inputs: entry_id, offset_ref |
describe_agent | Fleet-standard self-description. |
footprint | Aggregate footprint for an agent: total J, kWh, gCO2e, cost, and mean Landauer efficiency. Totals are exact sums of the ledger entries. Inputs: agent_id |
get_inventory | Fetch one immutable inventory record by inventory_id. Inputs: inventory_id |
list_entries | List all ledger entries for an agent. Inputs: agent_id |
list_inventories | List the separate GHG inventory chain for an agent. Inputs: agent_id |
record_inventory | 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. Inputs: agent_id, inventory_id, mass_g, content_digest, factor_pack_version, factor_pack_digest |
record_work | 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 ar Inputs: agent_id, entry_id, power_w, duration_s, task, bit_ops |
verify_attestation | Verify an attestation by recomputing the entry hash. Inputs: attestation |
verify_chain | Verify the tamper-evident hash chain of an agent's ledger. Inputs: agent_id |
verify_inventory_chain | Verify an agent's inventory hash chain independently of compute work. Inputs: agent_id |

It answered our last check on 22 October 2026 in 321 ms. Over 6 checks since 11 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
12, as returned by the server's own tools/list on 14 September 2026: attest, carbon_receipt, describe_agent, footprint, get_inventory, list_entries, list_inventories, record_inventory, and 4 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.viridisconservation.com/compute-ledger/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.jdhart81. Endpoint host: mcp.viridisconservation.com. ARD identifier: urn:air:io.github.jdhart81:mcp:agent-compute-ledger.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
