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

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

## Why modify_file is rated Medium

The tool name 'modify_file' unambiguously indicates a write operation that creates or modifies files. In the context of a pentesting/security research server (HexStrike AI), file modification could include updating payloads, scripts, or configurations. While the empty description prevents full context, the name itself is sufficiently clear. This is Write (not Destructive) because modification is typically reversible.

From the tool's own definition: "Tool name is 'modify_file' which directly indicates creation or modification of data. Description is empty, reducing confidence but not changing the core classification."

## Use case

AI agents use modify_file to create or update resources in Hexstrike Ai, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Hexstrike Ai environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Hexstrike Ai:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "modify_file": {
      "limits": [
        {
          "counter": "modify_file_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
