## Tools
- 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_project_id, serial_number, vintage, methodology) so
    retirements are cross-referenceable on registry.verra.org. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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 take. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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 these under the Viridis Verra account to finalize the
    on-registry retirement (portal today; auto-posts when Verra's transaction
    API is live). Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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 exact fills/cost without mutating the book. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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 accrued in a ledger. Idempotent on purchase_id;
    dry_run=true previews without mutating. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- net_position - Buyer's carbon position: emitted (from agent-compute-ledger) minus
    retired. carbon_accountable == true when fully offset. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- verify_certificate - Verify an offset certificate: recompute its hash and check the ledger. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- book - The full credit book with per-credit and book-wide mass conservation totals. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- get_purchase - Fetch a past purchase / offset certificate by id. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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 / shortfall_g and the backing
    credits. Read-only. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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 registered. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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 is what makes the clearinghouse fund restoration. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- list_projects - List all registered restoration projects with their metadata. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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-unregistered projects are surfaced separately as
    pending_registration (can't pay an unverified project). Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- 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 certified investment record the CEO executes the actual
    Stripe transfers against. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- verify_disbursement - Recompute the disbursement certificate hash chain and confirm whole-book
    conservation of disbursed proceeds. Any party can audit disbursements. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
- describe_agent - Fleet-standard self-description. Endpoint: https://mcp.viridisconservation.com/offsets/mcp
