接入MCP成功后，发送请求报错

问题描述

使用deepcode-cli接入vociebox的mcp后，输入提示词但报错Request failed: 400 Invalid 'tools[7].function.name': string does not match pattern. Expected a string that matches the pattern '^[a-zA-Z0-9_-]+$'.

复现步骤

• 安装voicebox
• 给deepcode-cli配置voicebox的MCP

{
  "env": {
    "MODEL": "deepseek-v4-pro",
    "BASE_URL": "https://api.deepseek.com",
    "API_KEY": "sk-xxxxxxxxxxxxxxxxxxxxxxxxxx"
  },
  "thinkingEnabled": true,
  "reasoningEffort": "max",
  "mcpServers": {
    "voicebox": {
      "command": "D:\\voicebox\\voicebox-mcp.exe",
      "env": {
        "VOICEBOX_CLIENT_ID": "deepcode-cli"
      }
    }
  }
}

• 终端进入deepcode，使用/mcp可以成功看到mcp服务已经Ready，✓ voicebox Ready (4 tools, 0 prompts, 0 resources)，且只有voicebox一个mcp
• 重启deepcode，输入提示词“你好“
• 报错equest failed: 400 Invalid 'tools[7].function.name': string does not match pattern. Expected a string that matches the pattern '^[a-zA-Z0-9_-]+$'.

关于voicebox的MCP

• 支持HTTP MCP客户端包括claude code、cursor、vs code等，但deepcode-cli中配置失败，deepcode-cli不支持下面格式的MCP

{
  "mcpServers": {
    "voicebox": {
      "url": "http://127.0.0.1:17493/mcp",
      "headers": {
        "X-Voicebox-Client-Id": "claude-code"
      }
    }
  }
}

• 可以使用适用于仅启动 stdio 进程的客户端。deepcode-cli支持此模式

{
  "mcpServers": {
    "voicebox": {
      "command": "C:\\Program Files\\Voicebox\\voicebox-mcp.exe",
      "env": {
        "VOICEBOX_CLIENT_ID": "claude-code"
      }
    }
  }
}

系统和版本

• win11系统
• deepcode-cli: 0.1.26
• voicebox: 0.5.0
