Why get_dbfs_file_info needs a policy

This tool retrieves metadata about files and directories in Databricks File System (DBFS) without creating, modifying, deleting, or executing anything. It is purely informational and presents minimal risk even if misused by an AI agent, as the worst outcome would be discovering file structure information that may already be accessible to the authenticated user.

From the tool's definition Tool name and description both indicate retrieval-only operation: 'Get file/directory information from DBFS' is a query/fetch action with no modification or execution.

POLICY

How to control get_dbfs_file_info

PolicyLayer is an MCP gateway — it sits between your AI agents and Databricks MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_dbfs_file_info:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_dbfs_file_info": {}
  }
}

get_dbfs_file_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Databricks MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
