WHAT IT DOES

What hippo_detect_anomalies does on Verimem

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

RISK

Why hippo_detect_anomalies is rated Low

This tool retrieves and analyzes data to identify anomalies within the bi-temporal memory engine. Detection and pattern analysis are read-only operations that do not create, modify, delete, or execute code. The tool fits the 'Read' category as it queries and reports on existing memory state without side effects.

From the tool's definition Tool name 'hippo_detect_anomalies' and description 'detect anomalous episodes' indicate analysis and detection of patterns in existing memory data without modification, deletion, or execution of external commands.

RECOMMENDED RULE

The rule that runs hippo_detect_anomalies safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Verimem, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hippo_detect_anomalies, this is the rule to start with:

hippo_detect_anomalies Allowed

hippo_detect_anomalies is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
