wechat_short_url

THE RISK

High Risk

This tool triggers an external operation via the WeChat API to transform a long URL into a short URL. It's not a pure read (it creates a new resource/mapping on WeChat's servers), but it's also not a direct write to user-owned data. It best fits Execute as it invokes an external WeChat service operation. Misuse could be used to obscure malicious URLs, hence medium severity.

From the tool's definition 将长URL转换为短链接 (converts long URLs to short links)

HOW TO CONTROL WECHAT_SHORT_URL

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

policy.json

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

wechat_short_url 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 WeChat Official Account MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
