## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1393 tokens (~73/item across 19 items; 19 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-02 (score 72, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (19)

### `list_credit` (~173 tokens)

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.

Input parameters:

- `issuer` (string, required)
- `mass_g` (integer, required)
- `methodology` (string)
- `price_minor_per_kg` (integer, required)
- `project_id` (string, required)
- `registry` (string)
- `serial_number` (string)
- `vcs_project_id` (string)
- `verification_ref` (string, required)
- `vintage` (string)

Output parameters:

- `result` (string)

### `delist_credit` (~66 tokens)

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.

Input parameters:

- `credit_id` (string, required)
- `reason` (string, required)

Output parameters:

- `result` (string)

### `verra_supply` (~68 tokens)

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.

Output parameters:

- `result` (string)

### `verra_retirement_record` (~118 tokens)

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).

Input parameters:

- `purchase_id` (string, required)
- `retirement_reason` (string)

Output parameters:

- `result` (string)

### `buy_offset` (~101 tokens)

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.

Input parameters:

- `buyer` (string, required)
- `dry_run` (boolean)
- `mass_g` (integer, required)
- `purchase_id` (string, required)

Output parameters:

- `result` (string)

### `buy_offset_budget` (~108 tokens)

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.

Input parameters:

- `budget_minor` (integer, required)
- `buyer` (string, required)
- `dry_run` (boolean)
- `purchase_id` (string, required)

Output parameters:

- `result` (string)

### `settlement_batch` (~74 tokens)

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.

Input parameters:

- `buyer` (string, required)
- `since` (string)

Output parameters:

- `result` (string)

### `net_position` (~51 tokens)

Buyer's carbon position: emitted (from agent-compute-ledger) minus
    retired. carbon_accountable == true when fully offset.

Input parameters:

- `buyer` (string, required)
- `emitted_g` (number, required)

Output parameters:

- `result` (string)

### `verify_certificate` (~29 tokens)

Verify an offset certificate: recompute its hash and check the ledger.

Input parameters:

- `certificate` (object, required)

Output parameters:

- `result` (string)

### `book` (~21 tokens)

The full credit book with per-credit and book-wide mass conservation totals.

Output parameters:

- `result` (string)

### `get_purchase` (~26 tokens)

Fetch a past purchase / offset certificate by id.

Input parameters:

- `purchase_id` (string, required)

Output parameters:

- `result` (string)

### `verify_retirement` (~92 tokens)

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.

Input parameters:

- `purchase_id` (string, required)
- `required_g` (integer)

Output parameters:

- `result` (string)

### `register_project` (~109 tokens)

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.

Input parameters:

- `beneficiary` (string)
- `location` (string)
- `methodology` (string)
- `name` (string)
- `project_id` (string, required)
- `registry_ref` (string)
- `verification_ref` (string, required)

Output parameters:

- `result` (string)

### `project_funding` (~82 tokens)

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.

Input parameters:

- `project_id` (string)

Output parameters:

- `result` (string)

### `list_projects` (~17 tokens)

List all registered restoration projects with their metadata.

Output parameters:

### `disbursement_schedule` (~91 tokens)

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).

Input parameters:

- `project_id` (string)

Output parameters:

- `result` (string)

### `certify_disbursement` (~92 tokens)

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.

Input parameters:

- `batch_id` (string, required)

Output parameters:

- `result` (string)

### `verify_disbursement` (~41 tokens)

Recompute the disbursement certificate hash chain and confirm whole-book
    conservation of disbursed proceeds. Any party can audit disbursements.

Output parameters:

- `result` (string)

### `describe_agent` (~13 tokens)

Fleet-standard self-description.

Output parameters:

- `result` (string)
