WHAT IT DOES

What create_directory does on Browser Automation MCP Server

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

WHY IT NEEDS A POLICY

Why create_directory needs a policy

Creating a directory is a reversible Write operation that modifies the filesystem. The lack of description lowers confidence slightly, but the name and context are clear. Severity is low because directory creation has minimal blast radius—it doesn't affect existing data and can be easily undone.

From the tool's definition Tool name 'create_directory' indicates directory creation; context shows file system operations (change_directory, list_directory, read_file_content, etc.) on a browser automation server.
