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 → Why this is hard to score →
Endpoint Security51
- 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 34 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability71
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 4511 tokens (~132/item across 34 items; 34 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management53
- Stability observed for 16 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage98
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 93% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 34 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 35 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

x402_preflight ~474
Should an agent pay this x402 endpoint? Pre-payment check of an UNKNOWN x402 URL: fetch it once (never pays) to validate the 402 challenge + accepts[] (scheme/network/payTo/amount/asset/resource = will it settle) AND label its LIVENESS (LIVE | ZOMBIE | DEAD — is it a working payable endpoint right now, or listed-active-but-broken) AND flag an absolute PRICE TRAP (a honeypot charging >= $1,000/call trips AVOID even when its advertised==live price looks self-consistent; pass max=<usdc> for your own budget ceiling) AND scan the resource + any advertised MCP tools for LLM01/LLM08 prompt-injection and screen payTo against the OFAC SDN + community scam lists (safe to pay) AND verify the PRICE — does the live accepts[].amount match the advertised price? pass advertised=<usdc> (the figure your catalog quoted) or it self-checks the endpoint's /.well-known/x402: MATCH | OVERCHARGE | UNDERCHARGE. Optional samples=N (1-5) runs a reliability/payability burst (settle-consistency + latency; a flapping endpoint downgrades PAY to CAUTION). Returns verdict PAY | CAUTION | AVOID + per-check fix hints + latency. Read-only, never a settlement guarantee. Cost: $0.001 USDC per call via x402.
| Name | Type | Req | Description |
|---|---|---|---|

| max | string | – | optional: your per-call budget ceiling in USDC dollars (e.g. 0.05) — the result flags price_trap.exceeds_caller_max if the live charge is over it; an absolute >=$1000/call trap trips AVOID regardless |
| samples | integer | – | optional reliability burst: sample the 402 challenge N times (1-5) for settle-consistency + latency; default 1 |

x402_receipt_verify ~290
Did my x402 payment actually settle? POST-payment on-chain proof — the other half of x402_preflight (which checks BEFORE paying). Bring your Base settlement tx hash + the resource URL you paid, and this reads the tx receipt from Base mainnet, decodes its USDC Transfer events, and reconciles them against the endpoint's advertised payTo + amount (resolved from the resource's live 402, or pass payto/expect to bind it directly). Returns verdict SETTLED | UNDERPAID | WRONG_RECIPIENT | NO_TRANSFER | REVERTED | NOT_FOUND | UNVERIFIED, the matched transfer, and all USDC transfers in the tx. Read-only ground truth; confirms settlement to the right address + amount, not off-chain resource delivery. Cost: $0.004 USDC per call via x402.

|---|---|---|---|
| expect | string | – | optional: advertised amount in USDC dollars (e.g. 0.004) to verify the settled amount against |

| tx | string | yes | 0x-prefixed 32-byte Base-mainnet settlement transaction hash |

No examples provided.
x402_receipt_verify_preview ~166
FREE keyless x402 settlement check on Base: pass a tx hash plus payto (and optionally expect, in USDC). Dual-RPC reads the receipt, decodes USDC Transfers and returns SETTLED | UNDERPAID | WRONG_RECIPIENT | NO_TRANSFER | REVERTED | NOT_FOUND. Binds to the payTo you supply; resolving the payTo from a live 402 url is the paid x402_receipt_verify.
| Name | Type | Req | Description |
|---|---|---|---|
| expect | string | – | optional: advertised amount in USDC dollars (e.g. 0.004) |
| payto | string | yes | 0x payTo address the payment should have reached |
