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

```json
{
  "jsonrpc": "2.0",
  "id": 1,

  "params": {
    "name": "write_memory",
    "arguments": {}
  }
}
```

## Why write_memory is rated Medium

Writing to process memory is a Write operation—it modifies data state. While it could enable destructive or execute-class harms depending on what is overwritten, the tool itself is fundamentally a reversible write operation (data can be restored). Severity is high because memory modification in an active process can cause immediate instability, crashes, or be leveraged for malicious code injection.

From the tool's own definition: "Tool name is 'write_memory' with empty description. Context indicates this is part of Frida Game Hacking MCP that provides 'memory scanning, value modification, pattern matching, function hooking, and code injection.' The write_memory tool directly modifies…"

## Use case

AI agents use write_memory to create or update resources in Frida Game Hacking MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frida Game Hacking MCP environment.
