Context Cost

~2,624Tokens (tool definitions)
~508 BTypical response size
Significant attention impact (2.05% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢enrich_domain(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).

⚪scan_mcp_server(url)

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).
