AI agents invoke award_game_xp to trigger processes or run actions in Vocab Voyage. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
award_game_xp can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access award_game_xp gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Award score-based XP from a game/activity (separate from study-time XP). Cascades to the leaderboard via DB trigger. Requires sign-in.. It is categorised as a Execute tool in the Vocab Voyage MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Vocab Voyage MCP server in PolicyLayer and add a rule for award_game_xp: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Vocab Voyage. Nothing to install.
award_game_xp is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the award_game_xp rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for award_game_xp. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
award_game_xp is provided by the Vocab Voyage MCP server (https://gponcrussdahcdyrlhcr.supabase.co/functions/v1/mcp-server?ref=mcp_registry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
