Send a text message to a 钉钉 group via webhook robot. Args: content: Message text. at_all: Whether to @all members.
AI agents use dingtalk_send_text to create or update resources in autoMate — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your autoMate environment.
This tool sends messages to a group chat (DingTalk is a Chinese communication/collaboration platform), which is a reversible write operation. It creates new data (messages) but does not execute code, delete data, or move money. The ability to @all members increases the blast radius (potential spam or unwanted notifications to many users), warranting medium severity rather than low.

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 dingtalk_send_text:
{
"version": "1",
"default": "deny",
"tools": {
"dingtalk_send_text": {
"limits": [
{
"counter": "dingtalk_send_text_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}dingtalk_send_text 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.
