WHAT IT DOES

What search_cross_agent does on Enhanced Knowledge Graph Memory Server

AI agents call search_cross_agent to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_cross_agent is rated Low

This tool retrieves and filters existing memory data based on search criteria and trust weights. There are no side effects, data modifications, or external operations triggered. The visibility filtering respects access controls rather than bypassing them. Confidence is high because the description clearly indicates a search/retrieval function with no state-changing operations.

From the tool's definition Tool performs 'search across agent memories' with 'trust-weighted scoring and visibility filtering'. This is a query/retrieval operation with no modification, deletion, or execution capabilities.

RECOMMENDED RULE

The rule that runs search_cross_agent safely

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

search_cross_agent Allowed

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