## 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**: 57/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 528 tokens (~58/item across 9 items; 9 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.

## MCP tools (9)

### `open_escrow` (~159 tokens)

Open an escrow between payer and payee. amount_minor is a positive
    integer in minor units (cents). The platform fee is computed and FROZEN at
    open (ceil bps). Returns the escrow_id (state OPEN). RETRY-SAFE: pass
    open_ref=<your job id> and a replayed open returns the ORIGINAL escrow
    (duplicate=true) instead of minting another one (E10).

Input parameters:

- `amount_minor` (integer, required)
- `currency` (string)
- `deadline` (string)
- `fee_bps`
- `open_ref` (string)
- `payee` (string, required)
- `payer` (string, required)
- `terms` (string)

Output parameters:

- `result` (string)

### `fund_escrow` (~49 tokens)

Mark an OPEN escrow as FUNDED (idempotent). payment_ref links the
    payment-rail transaction.

Input parameters:

- `escrow_id` (string, required)
- `payment_ref` (string)

Output parameters:

- `result` (string)

### `release_escrow` (~62 tokens)

Release a FUNDED/DISPUTED escrow to the payee (exactly-once — a repeat
    release returns the existing terminal record, never a double payout).

Input parameters:

- `delivery_proof` (string)
- `escrow_id` (string, required)

Output parameters:

- `result` (string)

### `refund_escrow` (~55 tokens)

Refund an OPEN/FUNDED/DISPUTED escrow to the payer (exactly-once).
    Refunding an OPEN escrow is a cancel.

Input parameters:

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

Output parameters:

- `result` (string)

### `dispute_escrow` (~54 tokens)

Move a FUNDED escrow to DISPUTED. An arbiter (agent-arbitration-agent)
    then resolves it to release or refund.

Input parameters:

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

Output parameters:

- `result` (string)

### `escrow_status` (~22 tokens)

Current record for an escrow.

Input parameters:

- `escrow_id` (string, required)

Output parameters:

- `result` (string)

### `list_escrows` (~43 tokens)

List escrows, optionally filtered by state
    (OPEN|FUNDED|RELEASED|REFUNDED|DISPUTED).

Input parameters:

- `state`

Output parameters:

- `result` (string)

### `verify_audit` (~31 tokens)

Validate the tamper-evident audit hash chain for an escrow.

Input parameters:

- `escrow_id` (string, required)

Output parameters:

- `result` (string)

### `describe_agent` (~13 tokens)

Fleet-standard self-description.

Output parameters:

- `result` (string)
