What get_project_categories does on Metis Public Health
AI agents call get_project_categories to retrieve information from Metis Public Health without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_project_categories is rated Low
This tool retrieves project metadata (categories) for display or filtering purposes. No modification, deletion, execution, or financial operations are indicated by the name or inferred from context. The empty description lowers confidence slightly, but the 'get_' prefix and categorical naming are strong signals of a read operation with minimal blast radius if misused by an agent.
From the tool's definition Tool name 'get_project_categories' follows a 'get_' prefix pattern consistent with retrieval operations (compare sibling 'get_' tools which are absent, but 'add_' verbs dominate the sibling list, suggesting 'get_' implies read-only queries).
Attacks that exploit this kind of access
The rule that runs get_project_categories safely

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