WHAT IT DOES

What scratchpad_open_workspace does on TTG Scratchpad MCP Server

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

WHY IT NEEDS A POLICY

Why scratchpad_open_workspace needs a policy

Opening or switching to a workspace modifies session/context state by changing the active workspace. This is a reversible state change (Write), not merely reading data. While the blast radius is moderate (it could expose a different workspace's data to subsequent operations), it doesn't directly delete or execute code.
