Multi-Debugger MCP Server (LLDB and GDB)

一个 Model Context Protocol 服务器，为 GDB 和 LLDB 调试器提供调试功能，可用于 Claude Desktop、VSCode Copilot 或其他 AI 助手。

快速开始

uv sync
uv venv
uv run server.py

Related MCP server: LLDB MCP Server

集成

请注意，你可以使用 uv run 运行 server.py 脚本，也可以使用 uv venv 创建虚拟环境，然后运行 /home/youruser/dev/personal/GDB-MCP/.venv/bin/python /home/youruser/dev/personal/GDB-MCP/server.py。

Claude Desktop

添加到你的 claude_desktop_config.json：

{
  "mcpServers": {
    "gdb": {
      "command": "uv",
      "args": ["run", "/home/youruser/dev/personal/GDB-MCP/server.py"],
      "disabled": false
    }
  }
}

VSCode Copilot

如果你使用的是 WSL：

 "mcp": {
    "servers": {
      "my-mcp-server-4dc36648": {
        "type": "stdio",
        "command": "wsl",
        "args": [
          "/home/youruser/dev/personal/GDB-MCP/.venv/bin/python",
          "/home/youruser/dev/personal/GDB-MCP/server.py"
        ]
      }
    }
  }

如果你不是在使用 WSL：

  "mcp": {
    "servers": {
      "my-mcp-server-db89eee1": {
        "type": "stdio",
        "command": "/home/youruser/dev/personal/GDB-MCP/.venv/bin/python",
        "args": ["/home/youruser/dev/personal/GDB-MCP/server.py"]
      }
    }
  }

Windsurf

{
  "mcpServers": {
    "debugger-mcp": {
      "command": "python3",
      "args": ["/Users/youruser/dev/GDB-MCP/server.py"]
    }
  }
}

实验性 LLDB 支持（macOS）

本项目在 GDB 之外还包含实验性的原生 LLDB 支持，并具有自动调试器选择功能。

安装

要在 macOS 上启用 LLDB 支持，请通过 Homebrew 安装 LLVM（其中包含 LLDB）和 python：

# Install LLDB for supporting python3.14 bindings
brew install llvm python3

# Install MCP and debugging dependencies
pip3 install mcp pygdbmi --break-system-packages

可用工具

统一工具

  • debugger_status()：显示可用的调试器及其状态

  • debugger_start()：使用自动检测到的调试器启动调试会话

  • debugger_terminate(session_id)：终止调试会话

  • debugger_list_sessions()：列出所有活动的调试会话

  • debugger_command(session_id, command)：执行调试器命令

LLDB 工具

  • lldb_start()：启动新的 LLDB 调试会话

  • lldb_terminate(session_id)：终止 LLDB 调试会话

  • lldb_list_sessions()：列出所有活动的 LLDB 会话

  • lldb_command(session_id, command)：执行任意 LLDB 命令

GDB 工具

  • gdb_start(gdb_path)：启动新的 GDB 调试会话

  • gdb_terminate(session_id)：终止 GDB 调试会话

  • gdb_list_sessions()：列出所有活动的 GDB 会话

  • gdb_command(session_id, command)：执行任意 GDB 命令

对于所有高级调试器操作，请使用 *_command() 函数，你的 LLM 客户端应该已经知道如何使用它，但提一下也无妨。

检查状态

你可以验证调试器的可用性：

from modules.lldb import LLDBSessionManager
from modules.gdb import GDBSessionManager

print("LLDB available:", LLDBSessionManager.is_available())
print("GDB available:", GDBSessionManager.is_available())

测试

uv run python run-tests.py --check-deps
uv run python run-tests.py --type all

示例

请查看 examples 目录中的示例提示词。

示例二进制文件编译为 arm64 和 amd64，请选择与你的系统架构匹配的那个。
