WHAT IT DOES

What list_members does on Plane

AI agents call list_members 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_members is rated Low

This tool performs a simple query to retrieve workspace members without creating, modifying, or deleting any data. It is a read-only operation with minimal blast radius if misused by an AI agent, as it only exposes already-accessible membership information.

From the tool's definition Tool name is 'list_members' and description states 'List all members of a workspace' - clearly a retrieval operation with no mutation or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_members 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_members, this is the rule to start with:

list_members Allowed

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

View as policy code

policy.json

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

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_members call is checked against it from then on.
