Reload the game preview. If the game is already running, it hot-reloads all assets. If the game is not running yet, it starts the game automatically (workspacePath required in that case).

AI agents invoke reload_game to trigger processes or run actions in Weixin Minigame Helper. 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.
reload_game 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 reload_game gives an agent. Each links to the full case and the policy that stops it:

Reload the game preview. If the game is already running, it hot-reloads all assets. If the game is not running yet, it starts the game automatically (workspacePath required in that case).. It is categorised as a Execute tool in the Weixin Minigame Helper MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Weixin Minigame Helper MCP server in PolicyLayer and add a rule for reload_game: 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 Weixin Minigame Helper. Nothing to install.
reload_game 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 reload_game 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 reload_game. 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.
reload_game is provided by the Weixin Minigame Helper MCP server (@weadmin/weixin-minigame-helper-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
