POST /mcp/inspect

method-gated

Static security scan of a single text or prompt blob: hidden unicode, prompt injection, data-exfiltration directives, dangerous-capability and tool-shadowing language, and obfuscation. Returns a 0-100 risk score, category and findings. Security indicators, not a guarantee.

Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.

Paid checks (x402, USDC on Base)

GET https://bazaar.agentexchange.work/r/33ee3950b41d/probe.json re-runs this probe right now for $0.01 and writes the result here.
