WHAT IT DOES

What list_project_labels does on Linear

AI agents call list_project_labels to retrieve information from Linear 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_project_labels is rated Low

This tool retrieves and lists existing labels without modifying, creating, or deleting any data. It is a read-only operation on project metadata. The blast radius of misuse is minimal—an agent could enumerate labels but cannot affect workspace state or data integrity.

From the tool's definition Tool name 'list_project_labels' and description 'List available project labels in the Linear workspace' indicate a query/retrieval operation with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_project_labels safely

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

list_project_labels Allowed

list_project_labels 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_project_labels": {}
  }
}

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

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