attach_moku · Moku MCP Server MCP: Risk & Policy

WHAT IT DOES

What attach_moku does on Moku MCP Server

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

WHY IT NEEDS A POLICY

Why attach_moku needs a policy

This tool establishes a connection to a Moku device and takes ownership of it, which is a reversible state change (ownership can be released via release_moku). It modifies the device's connection/ownership state but does not execute arbitrary commands, delete data, or involve financial transactions. Severity is medium because assuming ownership could disrupt other users/interfaces currently controlling the device.
