add_room · Mnehmos Synch MCP: Risk & Policy

WHAT IT DOES

What add_room does on Mnehmos Synch

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

WHY IT NEEDS A POLICY

Why add_room needs a policy

This tool creates new entities (folders/rooms) in the persistent context system, which is a reversible write operation. It modifies the organizational structure of the agent's memory store but does not execute arbitrary code, delete data, or move funds.

From the tool's definition Tool name 'add_room' and description 'Add a folder as a' indicate creation of a new organizational structure (room/folder) within the memory management system. The description is incomplete ('Add a folder as a' cuts off mid-sentence), which limits precision.

Verdict

add_room Rate-limited

add_room 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.
