安装

选择你的客户端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "gearboy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Gearboy"
      ]
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "gearboy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Gearboy"
      ]
    }
  }
}

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "gearboy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Gearboy"
      ]
    }
  }
}

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "gearboy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Gearboy"
      ]
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "gearboy-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Gearboy"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "gearboy-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/drhelius/Gearboy"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add gearboy-2 -- TODO 'See README: https://github.com/drhelius/Gearboy'

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。

使用场景

实战用法： Gearboy

How to debug a Game Boy ROM with AI assistance using Gearboy

👤 Homebrew Game Boy developers and ROM hackers ⏱ ~30 min intermediate

何时使用： You're developing a Game Boy homebrew ROM and need to debug runtime issues.

前置条件

Gearboy built with MCP support — Build from source following the GitHub README
A Game Boy ROM file (.gb or .gbc) — Your own homebrew ROM or a ROM you legally own

步骤

Load ROM and connect

Connect to the Gearboy MCP server and load my ROM. Show me the current CPU state and disassembly at the program counter.✓ 已复制

→ CPU registers, flags, and disassembled instructions at PC
Set a breakpoint and investigate

Set a breakpoint at address 0x0150 (after the header). Step through execution and explain what each instruction does.✓ 已复制

→ Step-by-step execution with instruction explanations
Inspect memory

Show me the contents of WRAM from 0xC000 to 0xC0FF. Are there any recognizable data structures?✓ 已复制

→ Memory dump with analysis of data patterns

结果： A clear understanding of how the ROM executes, with bugs identified and explained.

注意事项

Breakpoints on frequently-hit addresses slow execution dramatically — Use conditional breakpoints or set them only when you're close to the bug

搭配使用： filesystem

Learn Game Boy architecture interactively with AI and Gearboy

👤 Students learning retro console hardware and assembly ⏱ ~45 min intermediate

何时使用： You want to understand how the Game Boy CPU, memory, and graphics work hands-on.

前置条件

Gearboy with MCP server — Build from source
A simple test ROM — Use a homebrew test ROM or Blargg's test ROMs

步骤

Explore the memory map

Show me the Game Boy memory map. Read the ROM header at 0x0100-0x014F and explain each field.✓ 已复制

→ Annotated header with title, cartridge type, ROM/RAM sizes
Watch VRAM in action

Step through the VBlank interrupt handler and explain how tiles are loaded into VRAM.✓ 已复制

→ Step-by-step explanation of tile loading with VRAM state

结果： Hands-on understanding of Game Boy hardware through interactive exploration.

注意事项

Assembly can be overwhelming for beginners — Start with simple test ROMs that exercise one hardware feature at a time

组合

与其他 MCP 搭配，撬动十倍杠杆

gearboy-2 + filesystem

Export memory dumps and debug logs for offline analysis

Dump the entire VRAM contents to a file and annotate the tile data layout.✓ 已复制

工具

此 MCP 暴露的能力

工具	输入参数	何时调用
pause/resume/step	none / step_count?	Control emulator execution
read_memory	address: int, size: int	Read emulator memory at any address
write_memory	address: int, data: bytes	Write to emulator memory
set_breakpoint	address: int, type?: str	Set a CPU or memory breakpoint
disassemble	address: int, count: int	Disassemble instructions at an address
get_cpu_state	none	Get current CPU registers and flags

成本与限制

运行它的成本

API 配额: N/A — fully local
每次调用 Token 数: 100–500 tokens per debug command
费用: Free and open source (MIT license)
提示: Use targeted memory reads instead of full dumps to keep token usage low.

安全

权限、密钥、影响范围

凭据存储： N/A

数据出站： Fully local — no network calls

故障排查

常见错误与修复

MCP server not responding

Ensure Gearboy was built with MCP support enabled. Check that the server port (default 7777) is not in use.

验证： curl http://localhost:7777/health

ROM fails to load

Verify the ROM file is a valid .gb or .gbc file. Check the file isn't corrupted.

验证： Check the ROM header with a hex editor

Breakpoint never hits

Verify the address is in the execution path. Use the disassembler to check if code actually runs at that address.

验证： Disassemble around the target address
