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

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

~/.cursor/mcp.json · .cursor/mcp.json

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

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

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

~/.codeium/windsurf/mcp_config.json

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

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

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

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

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

加入 context_servers。Zed 保存后热重载。

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

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： Geargrafx

How to debug a PC Engine ROM with AI assistance using Geargrafx

👤 PC Engine homebrew developers and retro game researchers ⏱ ~30 min intermediate

何时使用： You're developing or analyzing a PC Engine ROM and need to debug runtime behavior.

前置条件

Geargrafx built with MCP support — Build from source following the GitHub README
A PC Engine ROM file (.pce or .sgx) — Your own homebrew ROM or a ROM you legally own

步骤

Connect and inspect

Connect to the Geargrafx MCP server. Show me the current HuC6280 CPU state and disassembly at the program counter.✓ 已复制

→ CPU registers and disassembled instructions
Analyze sprite system

Inspect the VDC sprite table. How many sprites are active and what tiles do they reference?✓ 已复制

→ Sprite attribute table with positions, tile indices, and flags

结果： Understanding of ROM execution and VDC hardware state for debugging.

注意事项

CD-ROM games require proper CUE/BIN setup — Ensure your CUE file paths are correct and all BIN tracks are present

搭配使用： filesystem

Learn PC Engine hardware architecture interactively

👤 Students and enthusiasts learning retro console hardware ⏱ ~45 min advanced

何时使用： You want to understand the HuC6280 CPU, VDC graphics, and PSG audio systems.

前置条件

Geargrafx with MCP server — Build from source

步骤

Explore the VDC

Step through the VBlank interrupt and explain how the PC Engine's VDC handles background scrolling and sprite rendering.✓ 已复制

→ Annotated explanation of VDC register writes and their effects

结果： Hands-on understanding of PC Engine hardware internals.

注意事项

SuperGrafx has two VDCs which complicates analysis — Start with regular PC Engine games before tackling SuperGrafx titles

组合

与其他 MCP 搭配，撬动十倍杠杆

geargrafx-2 + filesystem

Export debug data and memory dumps for documentation

Dump the VDC sprite table and tile data to files for analysis.✓ 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
set_breakpoint	address: int	Set a CPU breakpoint
disassemble	address: int, count: int	Disassemble HuC6280 instructions
get_hardware_status	none	Get VDC, VCE, and PSG register states

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 reads instead of full memory dumps.

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 Geargrafx was built with MCP support. Check the default port is available.

验证： Test the HTTP endpoint

CD-ROM game won't load

Verify CUE file references correct BIN paths. Try converting to CHD format.

验证： Check CUE file contents match actual BIN filenames

SuperGrafx ROM crashes

Only a handful of SuperGrafx games exist. Verify the ROM is actually an SGX title, not a regular PCE ROM.

验证： Check ROM header
