    How to connect

    How to connect agent-compute-ledger to Claude

    The server address to paste into Claude settings:

    https://mcp.viridisconservation.com/compute-ledger/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect agent-compute-ledger to ChatGPT

    The server address to paste into ChatGPT settings:

    https://mcp.viridisconservation.com/compute-ledger/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    How to connect agent-compute-ledger to Cursor

    The server address to paste into Cursor settings:

    https://mcp.viridisconservation.com/compute-ledger/mcp

    Fastest: click Open in Cursor below and confirm the prompt.

    Manually:

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
    3. Save the file. The server appears in the MCP list; authorize it there if asked.

    Authorization

    If the service needs sign-in, an authorize button appears next to the server in the MCP list.

    Server tool list (12)

    Raw names from tools/list. Only developers need these.

    record_workRecord 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.
    footprintAggregate footprint for an agent: total J, kWh, gCO2e, cost, and mean Landauer efficiency. Totals are exact sums of the ledger entries.
    attestIssue a content-addressed attestation for a ledger entry (verifiable green-compute / energy claim).
    verify_attestationVerify an attestation by recomputing the entry hash.
    verify_chainVerify the tamper-evident hash chain of an agent's ledger.
    list_entriesList all ledger entries for an agent.
    carbon_receiptEmit 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.
    record_inventoryRecord 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.
    get_inventoryFetch one immutable inventory record by inventory_id.
    list_inventoriesList the separate GHG inventory chain for an agent.
    verify_inventory_chainVerify an agent's inventory hash chain independently of compute work.
    describe_agentFleet-standard self-description.
