WHAT IT DOES

What net.rpki-validity does on Mcp

AI agents call net.rpki-validity to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why net.rpki-validity is rated Low

This is fundamentally a read-only security validation tool that queries public BGP/RPKI data to assess route legitimacy. It retrieves information and returns results (valid/invalid status, hijack signals, ROAs) without side effects.

From the tool's definition Tool performs RPKI Route Origin Validation — a query operation that 'checks' if an AS is authorized to originate a prefix. Returns status, ROAs, and description without modifying any data. Uses 'Live RIR/RPKI data via RIPEstat' for lookups.
