Update an existing project outline
AI agents use update_outline to create or update resources in Xiaohongshu (RedBook) MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Xiaohongshu (RedBook) MCP Server environment.
This tool creates or modifies data reversibly by updating an outline document within a project. It does not execute arbitrary code, delete data irreversibly, or move money. The severity is medium because misuse could modify content intended for social media publication, potentially causing reputational or compliance issues, but the effects are reversible via further updates or rollback.
From the tool's definition Tool name and description indicate it 'Update an existing project outline' — modifies existing data (the outline) in a reversible manner without deletion or financial implications.
Documented attack patterns abuse exactly the kind of access update_outline gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Xiaohongshu (RedBook) MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for update_outline:
{
"version": "1",
"default": "deny",
"tools": {
"update_outline": {
"limits": [
{
"counter": "update_outline_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} update_outline 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.

Update an existing project outline. It is categorised as a Write tool in the Xiaohongshu (RedBook) MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Xiaohongshu (RedBook) MCP Server MCP server in PolicyLayer and add a rule for update_outline: 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 (RedBook) MCP Server. Nothing to install.
update_outline 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 update_outline 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 update_outline. 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.
update_outline is provided by the Xiaohongshu (RedBook) MCP Server MCP server (xeron2000/redbookmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Xiaohongshu (RedBook) MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
