Available components
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. How we score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 399 tokens (~99/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage92
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 75% of tool parameters carry a description.Partial
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 21 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.
- 19 Aug 26 +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.

first_42_sponsor ~70
Pay Fieldproof $42. Returns every live rail: Stripe card_uri, EIP-681 usdc_uri, BIP-21 btc_uri, x402 POST /v1/sponsor, Zelle, and GET /v1/invoice. One settlement meets the first-$42 bar.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
policy_check ~181
Evaluate a proposed agent action against a policy and return allow / require_approval / deny with the matched rule and rationale. Paid per call via x402 ($0.005 USDC on Base); returns signing instructions when unpaid.
| Name | Type | Req | Description |
|---|---|---|---|
| ledger | object | – | Optional cumulative exposure for the window. A per-action gate cannot see repetition: 49 payments of $40 each pass a $50 rule individually. Omit it and any policy declaring a cumulative bound returns… |
| policy | object | – | Your own policy document, evaluated instead of ours |
| policy_id | string | – | Built-in policy id; see policy_rules. "default-action-tiers-capped" adds a cumulative spend bound. |
| request | object | yes | – |
No output schema declared.
No examples provided.
policy_example ~37
Free. Worked allow/require_approval/deny verdicts from the live policy engine, so you can judge the service before paying for it.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
policy_rules ~35
Free. The full built-in policy: every tier, rule, condition and rationale. Nothing about how a verdict is reached is hidden.
