## 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**: 46/100
  - AI-judged instruction clarity (poor).
  - Tool/resource definitions use about 694 tokens (~57/item across 12 items; 12 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.

### 2026-08-03 (score 69, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-01 (score 68, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-07-31 (score 67, +6)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-07-30 (score 61, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-07-29 (score 60, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (12)

### `record_work` (~153 tokens)

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.

Input parameters:

- `agent_id` (string, required)
- `bit_ops`
- `duration_s` (number, required)
- `entry_id` (string, required)
- `grid_intensity_g_per_kwh` (number)
- `power_w` (number, required)
- `price_minor_per_kwh`
- `task` (string)
- `temperature_k` (number)

Output parameters:

- `result` (string)

### `footprint` (~52 tokens)

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

Input parameters:

- `agent_id` (string, required)

Output parameters:

- `result` (string)

### `attest` (~38 tokens)

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

Input parameters:

- `entry_id` (string, required)

Output parameters:

- `result` (string)

### `verify_attestation` (~29 tokens)

Verify an attestation by recomputing the entry hash.

Input parameters:

- `attestation` (object, required)

Output parameters:

- `result` (string)

### `verify_chain` (~31 tokens)

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

Input parameters:

- `agent_id` (string, required)

Output parameters:

- `result` (string)

### `list_entries` (~24 tokens)

List all ledger entries for an agent.

Input parameters:

- `agent_id` (string, required)

Output parameters:

- `result` (string)

### `carbon_receipt` (~144 tokens)

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.

Input parameters:

- `entry_id` (string, required)
- `offset_ref` (string)

Output parameters:

- `result` (string)

### `record_inventory` (~108 tokens)

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.

Input parameters:

- `agent_id` (string, required)
- `content_digest` (string, required)
- `factor_pack_digest` (string, required)
- `factor_pack_version` (string, required)
- `inventory_id` (string, required)
- `mass_g` (integer, required)
- `source_ids`

Output parameters:

- `result` (string)

### `get_inventory` (~25 tokens)

Fetch one immutable inventory record by inventory_id.

Input parameters:

- `inventory_id` (string, required)

Output parameters:

- `result` (string)

### `list_inventories` (~29 tokens)

List the separate GHG inventory chain for an agent.

Input parameters:

- `agent_id` (string, required)

Output parameters:

- `result` (string)

### `verify_inventory_chain` (~29 tokens)

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

Input parameters:

- `agent_id` (string, required)

Output parameters:

- `result` (string)

### `describe_agent` (~13 tokens)

Fleet-standard self-description.

Output parameters:

- `result` (string)
