## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_states",
    "arguments": {}
  }
}
```

## Why list_states is rated Low

This tool queries and returns existing workflow state data without modifying, deleting, or executing any operations. It is a straightforward read operation that retrieves configuration information from the project management system.

From the tool's own definition: "Tool name 'list_states' and description 'List all workflow states in a project' indicate a retrieval operation with no side effects."

## Use case

AI agents call list_states 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Plane:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_states": {}
  }
}
```

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
