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

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

## Why evaluate_feature_flag is rated Low

Feature flag evaluation typically queries configuration state to determine which features are active, returning a boolean or flag value without side effects. No modification, deletion, code execution, or financial operations are implied. The tool fits the Read category despite the uninformative description.

From the tool's own definition: "Tool name 'evaluate_feature_flag' suggests a query operation that retrieves the state of a feature flag configuration. The empty description limits confidence, but feature flag evaluation is inherently a read operation."

## Use case

AI agents call evaluate_feature_flag to retrieve information from Mapi Agent Memory 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 Mapi Agent Memory:

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