AI agents use create_xhs_client to create or update resources in Xiaohongshu API MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Xiaohongshu API MCP Server environment.
This tool creates and initializes a new client instance, which is a Write operation—it creates new state in the system. It requires authentication credentials (Cookie), which is a security concern because improper credential handling could lead to unauthorized access. However, client instantiation itself is reversible (clients can be destroyed), so it doesn't qualify as Destructive.
From the tool's definition '创建一个新的小红书客户端实例' (creates a new Xiaohongshu client instance) and 'returns client ID' indicates creation of a new resource/state. The tool accepts Cookie authentication, establishing a persistent client session that modifies the state of the system.
Documented attack patterns abuse exactly the kind of access create_xhs_client gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Xiaohongshu API MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_xhs_client:
{
"version": "1",
"default": "deny",
"tools": {
"create_xhs_client": {
"limits": [
{
"counter": "create_xhs_client_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_xhs_client 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 Xiaohongshu API MCP Server MCP server in PolicyLayer and add a rule for create_xhs_client: 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 Xiaohongshu API MCP Server. Nothing to install.
create_xhs_client 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_xhs_client 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_xhs_client. 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_xhs_client is provided by the Xiaohongshu API MCP Server MCP server (proerror77/xhs_mcp_agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Xiaohongshu API MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
