Why workflowy_uncomplete_node needs a policy

The tool changes the completion status of a task/node from completed to incomplete. This is a Write operation because it modifies data in a reversible manner—the change can be undone by re-completing the node. It is not Read (no data retrieval), not Execute (no code execution or external command), not Destructive (reversible), not Financial.

From the tool's definition Tool name is 'workflowy_uncomplete_node' and description states 'Mark a WorkFlowy node as not completed'. This modifies the completion status of an existing node, which is a reversible state change to data.

POLICY

How to control workflowy_uncomplete_node

PolicyLayer is an MCP gateway — it sits between your AI agents and WorkFlowy MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for workflowy_uncomplete_node:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "workflowy_uncomplete_node": {
      "limits": [
        {
          "counter": "workflowy_uncomplete_node_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

workflowy_uncomplete_node 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about workflowy_uncomplete_node

What does the workflowy_uncomplete_node tool do? +

Mark a WorkFlowy node as not completed. It is categorised as a Write tool in the WorkFlowy MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on workflowy_uncomplete_node? +

Register the WorkFlowy MCP Server MCP server in PolicyLayer and add a rule for workflowy_uncomplete_node: 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 WorkFlowy MCP Server. Nothing to install.

What risk level is workflowy_uncomplete_node? +

workflowy_uncomplete_node is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit workflowy_uncomplete_node? +

Yes. Add a rate_limit block to the workflowy_uncomplete_node 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.

How do I block workflowy_uncomplete_node completely? +

Set action: deny in the PolicyLayer policy for workflowy_uncomplete_node. 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.

What MCP server provides workflowy_uncomplete_node? +

workflowy_uncomplete_node is provided by the WorkFlowy MCP Server MCP server (vladzima/workflowy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every WorkFlowy MCP Server tool call.

Start from WorkFlowy MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
