AI agents call lookup_property_base to retrieve information from Homedata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to be a foundational property data lookup function. Given the server's explicit focus on querying property data (EPCs, sale history, planning, flood risk, council tax, demographics) and the naming convention matching other read-only sibling tools, this is classified as Read.
From the tool's definition Tool name 'lookup_property_base' with prefix 'lookup' and suffix 'base' suggests data retrieval. Server description explicitly states the purpose is to 'query UK property data' with no mention of modifications or destructive actions.

lookup_property_base is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the lookup_property_base rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for lookup_property_base. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
