initialize · Idelrpg MCP: Risk & Policy

WHAT IT DOES

What initialize does on Idelrpg

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

WHY IT NEEDS A POLICY

Why initialize needs a policy

This tool creates new local state files (RPG state, hero profile, companion data) stored locally in the repository. It is a write/create operation with no destructive, financial, or execution implications. Blast radius is low since it only initializes local game state files.

From the tool's definition "Create repo-local IDEL RPG state, hero profile, and starting Patchling companion"

Verdict

initialize Rate-limited

initialize 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.
