## Why databricks_update_metastore is rated Medium

Updating a metastore modifies configuration and metadata that affects data governance, permissions, and catalog structure across an organization. This is reversible (Write, not Destructive), but has high blast radius if misconfigured by an AI agent. Severity is high rather than critical because metastore updates typically require elevated privileges and don't directly delete data or move money.

From the tool's own definition: "Tool name is 'databricks_update_metastore'; 'update' indicates modification of data. Metastores are central Databricks metadata repositories controlling catalog, schema, and table definitions. The description is empty, limiting certainty."

## Use case

AI agents use databricks_update_metastore to create or update resources in Databricks MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Databricks MCP Server environment.
