MCP tools · 2 exposed · ~167 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
check_ip ~105

Check if an IP address is internet background noise or potentially targeted activity. GreyNoise tracks IPs that mass-scan the internet. If an IP is 'noise', traffic from it is likely untargeted scanning. If it's NOT noise, traffic may be targeted at you specifically. RIOT dataset contains known-good IPs (CDNs, DNS servers, etc.).

No examples provided.

check_ips ~62

Check multiple IP addresses against GreyNoise in one call. Useful for triaging a list of suspicious IPs from logs or alerts. Rate limits apply (50/day for free tier).
