manage_condition · ChatRPG MCP: Risk & Policy

WHAT IT DOES

What manage_condition does on ChatRPG

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

WHY IT NEEDS A POLICY

Why manage_condition needs a policy

This tool creates or modifies data (D&D conditions) in a reversible manner. Adding/removing conditions and ticking duration are Write operations—they change game state but are not destructive since conditions can be removed or re-applied. Within the gaming context, misuse could disrupt gameplay balance (e.g., applying unwanted conditions), justifying medium severity.

From the tool's definition Tool performs state modifications (add, remove, tick duration) on game conditions; the verbs 'add' and 'remove' indicate reversible write operations that alter game state.

Verdict

manage_condition Rate-limited

manage_condition 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.
