WHAT IT DOES

What databricks_pin_cluster does on Databricks MCP Server

AI agents use databricks_pin_cluster 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.

RISK

Why databricks_pin_cluster is rated Medium

Pinning a cluster modifies cluster configuration or state reversibly—it does not execute arbitrary code, delete data, or move money. The empty description reduces confidence, but the name and server context (Databricks Compute management) indicate this is a Write operation that changes cluster properties.

From the tool's definition Tool name 'databricks_pin_cluster' indicates modification of cluster state (pinning), and context shows sibling tools like databricks_create_cluster and databricks_create_alert that perform Write operations.

RECOMMENDED RULE

The rule that runs databricks_pin_cluster safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Databricks MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For databricks_pin_cluster, this is the rule to start with:

databricks_pin_cluster Rate-limited

databricks_pin_cluster stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
