Agent Offset Clearinghouse is an MCP server with 19 tools an agent can call, among them book, buy_offset, buy_offset_budget. It answers at https://mcp.viridisconservation.com/offsets/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.
Verified conservation credits matched to agent compute emissions — the conservation flywheel of the
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
book | The full credit book with per-credit and book-wide mass conservation totals. |
buy_offset | Retire mass_g of verified credits for a buyer: cheapest-first matching, exactly-once (idempotent on purchase_id), returns a content-addressed offset certificate with per-fill costs. Payment settles via escrow. dry_run=true previews the exac Inputs: buyer, purchase_id, mass_g, dry_run |
buy_offset_budget | Money-denominated offset purchase: retire the maximum cheapest-first verified mass whose exact cost fits inside budget_minor (never overspends). Built for callers whose restoration obligation is a currency amount — e.g. a revenue share accr Inputs: buyer, purchase_id, budget_minor, dry_run |
certify_disbursement | Freeze the current disbursement schedule into a certified, tamper-evident batch (content-addressed, hash-chained). Idempotent on batch_id; only newly-accrued proceeds for verified projects are certified (never disbursed twice). This is the Inputs: batch_id |
delist_credit | Admin operation: remove a credit from the active fill path while retaining its listing and retirement history for audit. Idempotent for an already-delisted credit. Gateway state-change authentication is required. Inputs: credit_id, reason |
describe_agent | Fleet-standard self-description. |
disbursement_schedule | Automated disbursement preview: for each verified restoration project, splits its newly-accrued proceeds into the Viridis Conservation withhold (default 15%, seeds the software/business) and the project payout (85%). Read-only. Funded-but-u Inputs: project_id |
get_purchase | Fetch a past purchase / offset certificate by id. Inputs: purchase_id |
list_credit | List a conservation credit on the book. verification_ref (a D-Score / land-verification attestation) is REQUIRED — unverified credits cannot enter the book. To trade on the Verra network, pass registry="verra" with the VCS provenance (vcs_p Inputs: issuer, project_id, mass_g, price_minor_per_kg, verification_ref, registry |
list_projects | List all registered restoration projects with their metadata. |
net_position | Buyer's carbon position: emitted (from agent-compute-ledger) minus retired. carbon_accountable == true when fully offset. Inputs: buyer, emitted_g |
project_funding | Supply-side disbursement ledger: how much each restoration project has earned from retirements and is owed (gross_proceeds_minor + retired_g). Pass a project_id for one project, else all. Read-only — the CEO settles the actual payout. This Inputs: project_id |
register_project | Register a VERIFIED restoration project so retirements against its credits can be funded. verification_ref (D-Score / land-verification / registry id) is required — only verified conservation is funded. project_id is immutable once register Inputs: project_id, verification_ref, name, location, methodology, beneficiary |
settlement_batch | Read-only cash-settlement summary for a buyer: the list + exact sums (purchases, mass_g, cost_minor) of their retirements, optionally since an ISO-8601 timestamp — the statement a human settles in one transfer. Inputs: buyer, since |
verify_certificate | Verify an offset certificate: recompute its hash and check the ledger. Inputs: certificate |
verify_disbursement | Recompute the disbursement certificate hash chain and confirm whole-book conservation of disbursed proceeds. Any party can audit disbursements. |
verify_retirement | x402-C C4 check: confirm a retirement (offset_ref = purchase_id) actually retires at least required_g grams of verified conservation credit — the check that lets a carbon receipt's neutrality claim be honored. Returns covered / retired_g / Inputs: purchase_id, required_g |
verra_retirement_record | Generate the Verra-portal-ready retirement record(s) for a retirement made against Verra supply — VCS project id, serial, vintage, methodology, quantity (tCO2e), beneficiary, and the registry.verra.org cross-reference. Read-only. Submit the Inputs: purchase_id, retirement_reason |
verra_supply | The tradeable Verra VCS book: verified credits carrying genuine Verra provenance (project id + serial + vintage), cross-referenceable on registry.verra.org. Read-only. Every retirement nets the project 85% and Viridis the 15% marketplace ta |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.viridisconservation.com/offsets/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.
