  • Resource management and tool invocation
  • Flexible prompt system

Supported Clients

mcp2tcp supports all clients implementing the MCP protocol, including:

• Claude Desktop (Test ok)
• Continue (Should work)
• Cline (Test ok)

Quick Start

make sure you have installed uv

```bash
windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
MacOS
curl -LsSf https://astral.sh/uv/install.sh | sh

Basic Configuration

Add the following to your MCP client configuration:

{
    "mcpServers": {
        "mcp2tcp": {
            "command": "uvx",
            "args": ["mcp2tcp"]
        }
    }
}

Serial Port Configuration

Create or modify config.yaml to configure serial port parameters:

tcp:
  # TCP服务器配置
  remote_ip: "127.0.0.1"  # 远端IP地址
  port: 9999  # 端口号
  connect_timeout: 3.0  # 连接超时时间，单位为秒
  receive_timeout: 2.0  # 接收超时时间，单位为秒
  communication_type: "client"  # 通信类型，client或server
  response_start_string: "CMD"  # 可选，TCP应答的开始字符串，默认为OK

commands:
  # PWM控制命令
  set_pwm:
    command: "CMD_PWM {frequency}"  # frequency为0-100的整数，表示PWM占空比
    need_parse: false  # 不需要解析响应内容
    data_type: "ascii"  # 数据类型，ascii或hex
    parameters:
      - name: "frequency"
        type: "integer"
        description: "PWM frequency value (0-100)"
        required: true
    prompts:
      - "把PWM调到最大 (frequency=100)"
      - "把PWM调到最小 (frequency=0)"
      - "请将PWM设置为{frequency} (0-100的整数)"
      - "关闭PWM (frequency=0)"
      - "把PWM调到一半 (frequency=50)"

  # PICO信息查询命令
  get_pico_info:
    command: "CMD_PICO_INFO"  # 实际发送的命令格式，server会自动添加\r\n
    need_parse: true  # 需要解析响应内容
    data_type: "ascii"  # 数据类型，ascii或hex
    prompts:
      - "查询Pico板信息"
      - "显示开发板状态"

Configuration File Location

The configuration file (config.yaml) can be placed in different locations depending on your needs. The program searches for the configuration file in the following order:

1. Current Working Directory (For Development)

• Path: ./config.yaml
• Example: If you run the program from C:\Projects, it will look for C:\Projects\config.yaml
• Best for: Development and testing
• No special permissions required

2. User's Home Directory (Recommended for Personal Use)

• Windows: C:\Users\YourName\.mcp2tcp\config.yaml
• macOS: /Users/YourName/.mcp2tcp/config.yaml
• Linux: /home/username/.mcp2tcp/config.yaml
• Best for: Personal configuration
• Create the .mcp2tcp directory if it doesn't exist
• No special permissions required

3. System-wide Configuration (For Multi-user Setup)

• Windows: C:\ProgramData\mcp2tcp\config.yaml (requires admin rights)
• macOS/Linux: /etc/mcp2tcp/config.yaml (requires sudo/root)
• Best for: Shared configuration in multi-user environments
• Create the directory with appropriate permissions

The program will use the first valid configuration file it finds in this order. Choose the location based on your needs:

• For testing: use current directory
• For personal use: use home directory (recommended)
• For system-wide settings: use ProgramData or /etc
