AI agents use wecom_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.
Sending a message creates new data (a message) in an external system. This is a Write action. The blast radius is medium — an AI agent could send unauthorized messages to colleagues or groups, but it does not destroy data or move money. Confidence is reduced due to the empty description.
From the tool's definition Tool name 'wecom_send_text' suggests sending a text message via WeCom (WeChat Work); description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access wecom_send_text gives an agent:
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 wecom_send_text:
{
"version": "1",
"default": "deny",
"tools": {
"wecom_send_text": {
"limits": [
{
"counter": "wecom_send_text_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}wecom_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.

wecom_send_text. It is categorised as a Write tool in the autoMate MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the autoMate MCP server in PolicyLayer and add a rule for wecom_send_text: 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 autoMate. Nothing to install.
wecom_send_text is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the wecom_send_text 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 wecom_send_text. 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.
wecom_send_text is provided by the autoMate MCP server (yuruotong1/automate). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
