persona-4-golden -real-time-hacking

This MCP server is a Rust-based memory hacking tool for Persona 4 Golden. It locates the P4G.exe process, resolves the in-memory pointer path to the in-game money value, and writes a user-specified amount directly into memory in real-time. The server exposes a ready-to-run executable that you launch via MCP configuration; once running, you can chat with Claude (or your configured agent) to issue a command like setting your in-game money. The flow is designed for precision and low overhead, leveraging native Windows APIs to read and write memory in the target process. Use this to adjust in-game currency on the fly without external cheats or overlays.

• Prerequisites:

  • Windows operating system (tested on Windows 11)
  • Persona 4 Golden (Steam version) installed
  • Rust toolchain (stable) installed

• Clone the repository and build:

git clone https://github.com/your-name/persona-4-golden-mcp-hack.git
cd persona-4-golden-mcp-hack
cargo build --release --example persona_4_golden_mcp_hack

• Configure MCP to run the executable:

{
  "mcpServers": {
    "persona4golden": {
      "command": "PATH-TO/persona-4-golden-mcp-hack/target/release/examples/persona_4_golden_mcp_hack.exe",
      "args": []
    }
  }
}

• Run with MCP: ensure your MCP environment loads the above config and starts the server binary. You may need to run with appropriate permissions to access the target process (administrator mode is commonly required).

• Verify operation: launch Persona 4 Golden and verify that the command channel (via Claude or your MCP client) can read/write the in-game money value in real-time.

Tips and common issues:

• Ensure the path in the config points to the compiled release executable; use the exact path from your build environment.
• Running with insufficient privileges can prevent memory access. If you encounter access denied errors, try running the MCP client and the target executable as Administrator.
• The tool relies on the game's memory layout; updates to Persona 4 Golden or Steam patches may require re-basing or pointer path updates.
• If the tool cannot locate P4G.exe, verify that the process name matches exactly and that the game is running.
• Keep environment variables minimal; the current setup uses default env (empty). If you extend functionality, document variables in the env section of the mcp_config.
