submit_review · Maiat Protocol MCP: Risk & Policy

WHAT IT DOES

What submit_review does on Maiat Protocol

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

WHY IT NEEDS A POLICY

Why submit_review needs a policy

This is a Write operation because it creates/stores new review records and modifies token balances reversibly. It is not Destructive because reviews can theoretically be amended or flagged, and the Scarab cost is refundable. It is not Financial because the primary purpose is data submission, not moving funds or creating financial obligations (the token cost is incidental to the review mechanism).

From the tool's definition The tool 'submit_review' writes review data to an on-chain system and modifies account state (deducts 5 Scarab tokens, potentially credits 1-3 Scarab back). It is described as submitting data that persists on-chain.
