## Facts

- Tool: `list_users`
- Server: Linear Kanban Server (`0xikarus/linear-kanban-mcp`) — https://policylayer.com/tools/0xikarus-linear-kanban-mcp.md
- Homepage: https://github.com/0xikarus/linear-kanban-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why list_users is rated Low

This tool retrieves and queries user information from the Linear workspace without creating, modifying, deleting, or executing operations. It has minimal blast radius as it only exposes read-access to user directory information that is typically accessible to workspace members.

From the tool's own definition: "Tool name is 'list_users' and description states it 'List all users in the Linear workspace'. The verb 'list' indicates data retrieval with no modification or side effects."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call list_users to retrieve information from Linear Kanban Server 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 Linear Kanban Server:

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