Security enrichment: tech-stack fingerprint + CVE mapping + EPSS + CISA KEV + verdict (clear/review/block) for a domain. Cost: $0.005 USDC per call (x402 micropayment).

Firmographic + tech-stack enrichment: RDAP registrant/registrar, DNS records, full subdomain enumeration + certificate-transparency history, tech-stack fingerprint, verdict (clear/review/block, based on domain age) for a domain. Cost: $0.005 USDC per call via the shared MCP payment gate (the direct HTTP endpoint GET /enrich/domain is $0.01 — MCP tools/call is gated at a flat $0.005 per request).

Security-audit a target MCP server for prompt-injection / tool-poisoning. Fetches the server's advertised tools and statically analyzes each for hidden instructions, data-exfiltration hints, dangerous capabilities, cross-tool shadowing, and invisible-unicode payloads (OWASP LLM01/LLM08). Returns findings + a 0-100 risk score + verdict (clear/review/block). Cost: $0.005 USDC per scan via x402 (GET /scan/mcp HTTP variant is $0.10).

FREE preview scan of a target MCP server for tool-poisoning / prompt-injection. Returns issue count, severity breakdown, risk score, and verdict (clear/review/block) — but NOT which tools or the evidence. Use this to check any MCP server (including your own) at no cost; if issues are found, call the paid scan_mcp_server for the itemized findings + remediation. No payment required.
