enrich_tech_risk | 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). params: domain, techstack |
enrich_domain | 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). params: domain* |
scan_mcp_server | 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 params: url* |
scan_mcp_preview | 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.

Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
