## 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**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (a2a_signup).
  - 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**: 40/100
  - Verified sse transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 188 tokens (~94/item across 2 items; 2 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**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `a2a_get_started` (~36 tokens)

Explains what A2A TrustGate is and how to activate this MCP server (no API key on this session yet).

### `a2a_signup` (~152 tokens)

Create a new A2A TrustGate tenant and get an API key (shown once), unlocking all safety tools in this session immediately. Agent-first: only a short tenant slug is required — no email or password. A human must then add a card (secure Stripe checkout) at the returned paymentUrl to activate; /v1 calls return 402 until activated.

Input parameters:

- `agent` (string): Agent/label creating the tenant (optional, e.g. "claude-code")
- `description` (string): What this tenant is for (optional)
- `tenantId` (string, required): Short tenant slug, 3-64 chars, lowercase alphanumeric + hyphens (e.g. "my-agent")
