weixin_send_template_message

THE RISK

High Risk

Sending a template message via WeChat is an external operation that delivers communications to end users. This falls under Execute as it triggers an external side-effecting operation. The description is empty, which lowers confidence, but the name strongly suggests outbound message delivery. Severity is high because an AI agent could misuse this to send messages to many users at scale.

From the tool's definition Tool name 'weixin_send_template_message' implies sending a message via WeChat (Weixin) template messaging API, which triggers an external operation (message delivery to users).

HOW TO CONTROL WEIXIN_SEND_TEMPLATE_MESSAGE

PolicyLayer is an MCP gateway — it sits between your AI agents and autoMate, and nothing reaches the server without passing your rules. This is the rule we recommend for weixin_send_template_message:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "weixin_send_template_message": {
      "limits": [
        {
          "counter": "weixin_send_template_message_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

weixin_send_template_message stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register autoMate — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
