doubao-search-mcp

基于火山引擎豆包联网搜索 API 的 MCP 服务,提供 web_search 工具(网页 / 图片搜索),帮助大模型 / AI Agent 获取更准确、更新鲜的外部信息。

本包复刻自火山官方 volcengine/mcp-server 的 mcp_server_askecho_search_infinity(MIT 协议),修复了 mcp SDK 2.x 下的导入崩溃问题,并独立发布到 PyPI。

功能

提供 web_search 工具:

参数 类型 默认 说明
Query str — 搜索 query,1~100 个字符(必填)
Count int 10 返回条数;web 最多 50,image 最多 5
SearchType str web 仅支持 web 或 image
TimeRange str 空 OneDay/OneWeek/OneMonth/OneYear 或日期区间 YYYY-MM-DD..YYYY-MM-DD
AuthLevel int 0 权威等级过滤;0 默认,1 非常权威

安装运行

需要 Python 3.12 / 3.13 与 uv。

# 免安装直接运行(首次自动从 PyPI 拉取)
uvx doubao-search-mcp

# 或安装成常驻工具
uv tool install doubao-search-mcp
doubao-search-mcp

传输方式

默认 stdio;也支持 SSE / streamable-http:

uvx doubao-search-mcp -t sse
uvx doubao-search-mcp -t streamable-http

鉴权

二选一,通过环境变量提供(两者都不配置会启动失败,日志提示 Authentication missing):

方式 环境变量
API Key ASK_ECHO_SEARCH_INFINITY_API_KEY
火山引擎 AK/SK VOLCENGINE_ACCESS_KEY + VOLCENGINE_SECRET_KEY

客户端配置

Claude Code

claude mcp add doubao-search-mcp \
  -e ASK_ECHO_SEARCH_INFINITY_API_KEY=你的Key \
  -- uvx doubao-search-mcp

通用 mcp.json / claude_desktop_config.json

{
  "mcpServers": {
    "doubao-search-mcp": {
      "command": "uvx",
      "args": ["doubao-search-mcp"],
      "env": {
        "ASK_ECHO_SEARCH_INFINITY_API_KEY": "你的Key"
      }
    }
  }
}

为什么锁 mcp<2

官方源码依赖 mcp>=1.9.4 未锁上限,而 mcp Python SDK 2.x 移除了 mcp.server.FastMCP 的导入路径,导致服务启动即崩溃。本包将依赖锁定为 mcp>=1.9.4,<2,保证在最新 1.x 上稳定运行;待上游适配 2.x 后再考虑升级。
