Agent readability score
Strengths
- Tool name 'ip_risk_lookup' directly reflects its purpose of assessing IP risk profiles.
- Parameter definition is explicit with clear type and required status.
Weaknesses
- Description is cut off mid-sentence ('The score is'), leaving critical information about risk scoring undefined.
- No documentation of error handling or constraints (e.g., invalid IP formats, rate limits).
ip_risk_lookup— Description truncation prevents full understanding of risk score methodology.

Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
ip_risk_lookupLook up the risk profile and geolocation of an IPv4 or IPv6 address. Returns a 0-100 risk score measuring the freshness and strength of verifiable risk evidence (proxy, VPN, dial-up pool, cloud phone, datacenter), the evidence state, network (ASN, usage type) and geographic attribution. The score is NOT a probability that the address is an attacker. Free tier: 1000 lookups per day per client IP and 60 per minute; higher limits with an API key sent as the X-API-Key header (https://ip99.com/en/pricing).
