AI agents use create_note to create or update resources in Xhs — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Xhs environment.
This tool creates and publishes new content (articles/notes) to a Xiaohongshu account without requiring explicit authentication from the account owner. While reversible (published content can be deleted), it represents a significant Write operation that modifies user-visible data and could be used to spam, impersonate, or abuse accounts if misused by an AI agent.
From the tool's definition Tool description states '将文章发布到某个手机号的小红书上' (publish articles to Xiaohongshu for a phone number) and 'can directly call this interface' without prior login. This is a create/publish operation that modifies the target account's content.
Documented attack patterns abuse exactly the kind of access create_note gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Xhs, and nothing reaches the server without passing your rules. This is the rule we recommend for create_note:
{
"version": "1",
"default": "deny",
"tools": {
"create_note": {
"limits": [
{
"counter": "create_note_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_note 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.

Register the Xhs MCP server in PolicyLayer and add a rule for create_note: 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 Xhs. Nothing to install.
create_note 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 create_note 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 create_note. 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.
create_note is provided by the Xhs MCP server (softegli/xhs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Xhs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
