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

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

## Why store_files is rated Medium

The tool creates/stores new files on the server by accepting uploaded file objects with base64-encoded data. This is a write operation (creating data), reversible in principle (files could be deleted), with medium severity as it could be misused to store malicious content or large amounts of data.

From the tool's own definition: "'Store uploaded files. Receives file objects with name, size, type, data (base64).'"

## Use case

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

## Recommended policy (PolicyLayer)

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

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