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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "analyze_readability",
    "arguments": {
      "text": "<text>"
    }
  }
}
```

## Why analyze_readability is rated Low

analyze_readability performs read-only text analysis using a standard readability algorithm. It accepts text input and returns calculated metrics (Flesch-Kincaid score, grade level, reading ease). This has no side effects, does not interact with external systems, and poses minimal security risk even if misused by an agent, as it cannot cause data loss, execute arbitrary commands, or trigger financial transactions.

From the tool's own definition: "Tool description states 'Calculate Flesch-Kincaid readability score, grade level, and reading ease' with parameter 'text — Text to analyze for readability.' This is a pure analysis/calculation operation that retrieves metrics from input text without…"

## Use case

AI agents call analyze_readability to retrieve information from X402 Middleware 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 X402 Middleware:

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