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

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

  "method": "tools/call",
  "params": {
    "name": "get_units",
    "arguments": {}
  }
}
```

## Why get_units is rated Low

The 'get_' prefix strongly indicates a retrieval operation with no side effects. Fetching unit definitions (e.g., cups, grams, liters) from a recipe management system is a read-only query. No data is created, modified, deleted, or executed. Confidence is not higher due to empty description, but the name and context provide sufficient evidence for Read classification.

From the tool's own definition: "Tool name 'get_units' indicates a retrieval operation. The empty description provides no contradictory evidence."

## Use case

AI agents call get_units to retrieve information from Mealie MCP 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 Mealie MCP Server:

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