claim_reward · Idelrpg MCP: Risk & Policy

WHAT IT DOES

What claim_reward does on Idelrpg

AI agents use claim_reward 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 claim_reward needs a policy

This tool writes/modifies game state by awarding XP and tokens to a player profile for a completed quest. It creates or updates locally stored game data (XP, tokens). While 'tokens' could imply financial value, the server description clarifies everything is stored locally in a gamified dev context with no real financial transactions.

Verdict

claim_reward Rate-limited

claim_reward 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.
