WHAT IT DOES

What list_labels does on Plane

AI agents call list_labels to retrieve information from Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_labels is rated Low

This tool performs a read-only operation that queries and retrieves label data from a project. It does not create, modify, delete, or execute any actions—it simply lists existing labels. This is a standard Read category operation with minimal risk.

From the tool's definition Tool name 'list_labels' and description 'List all labels in a project' indicate data retrieval with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_labels safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_labels, this is the rule to start with:

list_labels Allowed

list_labels is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_labels": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Plane, apply this rule, and every list_labels call is checked against it from then on.

How do I enforce a policy on list_labels? +

Register the Plane MCP server in PolicyLayer and add a rule for list_labels: 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 Plane. Nothing to install.

What risk level is list_labels? +

Can I rate-limit list_labels? +

How do I block list_labels completely? +

Set action: deny in the PolicyLayer policy for list_labels. 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 list_labels? +

list_labels is provided by the Plane MCP server (cmet7/plane-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
