AI agents use update_folder to create or update resources in ClickUp MCP Sedrver — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ClickUp MCP Sedrver environment.
This tool modifies existing folder properties in ClickUp, which is a reversible write operation. It does not delete data (would be Destructive), execute code (would be Execute), or move money (would be Financial). The severity is medium because an AI agent could reorganize workspace structure in unintended ways, affecting team collaboration and information access, but changes can be undone through subsequent updates.
From the tool's definition Tool name is 'update_folder' and description states 'Update an existing ClickUp folder', indicating modification of existing data.
Documented attack patterns abuse exactly the kind of access update_folder gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ClickUp MCP Sedrver, and nothing reaches the server without passing your rules. This is the rule we recommend for update_folder:
{
"version": "1",
"default": "deny",
"tools": {
"update_folder": {
"limits": [
{
"counter": "update_folder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_folder 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 ClickUp folder\. It is categorised as a Write tool in the ClickUp MCP Sedrver MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ClickUp MCP Sedrver MCP server in PolicyLayer and add a rule for update_folder: 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 ClickUp MCP Sedrver. Nothing to install.
update_folder 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_folder 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_folder. 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_folder is provided by the ClickUp MCP Sedrver MCP server (nsxdavid/clickup-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
