WHAT IT DOES

What create_knowledge_database does on Metis Public Health

AI agents use create_knowledge_database to create or update resources in Metis Public Health, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Metis Public Health environment.

RISK

Why create_knowledge_database is rated Medium

The verb 'create' combined with 'knowledge_database' suggests this tool creates or initializes a new data structure. This is a Write action (reversible modification of data). Severity is medium because database creation could consume resources or overwrite existing schemas, but lacks the destructive finality of deletion or the blast radius of Execute/code-execution.

From the tool's definition Tool name 'create_knowledge_database' indicates creation of a database artifact. Description is empty, limiting specificity.
