Parameters from the server's own tool schema.
Why razz_react is rated Medium
Adding an emoji reaction creates or modifies data (the reaction metadata associated with a message) in a reversible manner. It does not retrieve data (Read), execute code or commands (Execute), delete data permanently (Destructive), or move money (Financial). The context of a gaming server with SOL wagering does not change the nature of this specific tool—it only adds metadata to messages.
From the tool's definition Tool description states 'Add an emoji reaction to a message', which creates a new message reaction object. This is a reversible modification operation (reactions can be removed).
Attacks that exploit this kind of access
The rule that runs razz_react safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Razz Games, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For razz_react, this is the rule to start with:
razz_react 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Razz Games, apply this rule, and every razz_react call is checked against it from then on.
