Nothing serious here today

Today is the operative word: we check Agent Compute Ledger every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 12

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

verify

verify_attestation

Verify an attestation by recomputing the entry hash.

verify_chain

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

verify_inventory_chain

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

record

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.

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 are rejected. Idempotent on entry_id.

attest

attest

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

carbon

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 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

describe_agent

Fleet-standard self-description.

entries

list_entries

List all ledger entries for an agent.

footprint

footprint

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

inventories

list_inventories

List the separate GHG inventory chain for an agent.

inventory

get_inventory

Fetch one immutable inventory record by inventory_id.

Agent Compute Ledger — questions

Answers built from our own checks of this server.

What can Agent Compute Ledger do?

It exposes 12 tools, read directly from the server on our last check. Among them: attest, carbon_receipt, describe_agent, footprint, get_inventory, list_entries and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Agent Compute Ledger mostly used for?

Its tools cluster around verify and record. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Agent Compute Ledger working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 416 ms. The bar chart above shows every period we have measured.

How do I connect Agent Compute Ledger?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Agent Compute Ledger need an API key?

No. Agent Compute Ledger completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Agent Compute Ledger?

It answers our handshake in 416 ms on average, which is faster than 36% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Agent Compute Ledger open source?

We cannot say either way: written in Python, 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
