Retrieve all contacts from the contacts table.
AI agents call get_contacts to retrieve information from Metis Public Health without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of stored contact data. The verb 'retrieve' and the absence of any modification, deletion, or execution capability clearly place this in the Read category. The severity is low because retrieving contact metadata has minimal blast radius unless the contacts themselves contain highly sensitive personal identifiers, which is not indicated in the description.
From the tool's definition Tool name 'get_contacts' and description 'Retrieve all contacts from the contacts table' indicate a data retrieval operation with no modification capability.
