## 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 2026-08-04.

- **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**: 49/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 300 tokens (~50/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 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.

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.

## MCP tools (6)

### `register_agent` (~99 tokens)

Register (or idempotently update) an agent identity. Returns a
    deterministic content-addressed DID. capabilities is a non-empty list of
    lowercase capability tags other agents can discover you by.

Input parameters:

- `agent_id` (string, required)
- `capabilities` (array, required)
- `endpoint` (string)
- `name` (string)
- `pricing`
- `pubkey` (string)
- `reputation_hint` (number)

Output parameters:

- `result` (string)

### `resolve_agent` (~37 tokens)

Resolve an identity by agent_id or DID to its full public registration.

Input parameters:

- `agent_id` (string)
- `did` (string)

Output parameters:

- `result` (string)

### `discover_agents` (~43 tokens)

Find ACTIVE agents matching ALL requested capabilities (AND semantics),
    deterministically ordered by match count then reputation.

Input parameters:

- `capabilities` (array, required)
- `limit` (integer)

Output parameters:

- `result` (string)

### `revoke_agent` (~46 tokens)

Revoke an identity: it disappears from discovery (terminal) but its
    record is retained for auditability.

Input parameters:

- `agent_id` (string)
- `did` (string)

Output parameters:

- `result` (string)

### `list_registrations` (~29 tokens)

List registrations, optionally filtered by status (ACTIVE|REVOKED).

Input parameters:

- `status`

Output parameters:

- `result` (string)

### `describe_agent` (~13 tokens)

Fleet-standard self-description.

Output parameters:

- `result` (string)
