## 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**: 66/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 370 tokens (~52/item across 7 items; 7 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 (7)

### `grant_covenant` (~98 tokens)

Grant an agent a covenant: an explicit lease of authority. scopes support
    wildcards ('payments.*', '*'); budget_minor is the total spend ceiling in
    minor units; expires_at is ISO-8601. Returns the covenant_id.

Input parameters:

- `agent_id` (string, required)
- `budget_minor` (integer, required)
- `expires_at` (string, required)
- `principal` (string, required)
- `scopes` (array, required)

Output parameters:

- `result` (string)

### `check_act` (~84 tokens)

Check (and if allowed, record) a proposed act against a covenant.
    Deny-by-default. Idempotent on act_id — retries never double-consume
    budget. Every check lands on the audit chain.

Input parameters:

- `act_id` (string, required)
- `amount_minor` (integer)
- `covenant_id` (string, required)
- `scope` (string, required)

Output parameters:

- `result` (string)

### `revoke_covenant` (~39 tokens)

Revoke a covenant immediately and terminally. All subsequent checks deny.

Input parameters:

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

Output parameters:

- `result` (string)

### `covenant_status` (~28 tokens)

Current state, consumed/remaining budget, and check count.

Input parameters:

- `covenant_id` (string, required)

Output parameters:

- `result` (string)

### `verify_audit` (~33 tokens)

Verify the tamper-evident audit chain of allowed/denied acts.

Input parameters:

- `covenant_id` (string, required)

Output parameters:

- `result` (string)

### `list_covenants` (~46 tokens)

List covenants, optionally filtered by state (ACTIVE|REVOKED|EXPIRED)
    and/or the bound agent.

Input parameters:

- `agent_id`
- `state`

Output parameters:

- `result` (string)

### `describe_agent` (~13 tokens)

Fleet-standard self-description.

Output parameters:

- `result` (string)
