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

```json
{
  "jsonrpc": "2.0",

    "name": "list_tool_groups",

## Why list_tool_groups is rated Low

This tool retrieves and displays information about available tool groups and their status. It performs no modifications, deletions, or external operations—it simply queries and returns state information. This is a classic Read operation. Severity is low because the information disclosed is only metadata about the Metis system itself, not sensitive user data or external resources.

From the tool's own definition: "list_tool_groups: List the tool groups that can be loaded on demand, with how many are parked. The verb 'List' and the passive retrieval of metadata about tool groups (counts, names) indicates a pure query operation with no side effects."

## Use case

AI agents call list_tool_groups to retrieve information from Metis Public Health 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 Metis Public Health:

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