AI agents call lookup_property_complete 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.
The tool appears to retrieve comprehensive property information from the Homedata API without modifying or deleting data. It fits the 'Read' category (queries data with no side effects). Severity is 'medium' rather than 'low' because property data can be sensitive (flood risk, crime, sales history, demographics, council tax bands) and misuse could enable privacy violations or social engineering.
From the tool's definition Tool name 'lookup_property_complete' and server description indicate this queries UK property data (EPCs, sale history, planning, flood risk, council tax, demographics).
