deepseek-search-mcp
This server provides multi-backend web search and URL content fetching via MCP, powered by DeepSeek V4-Flash and Xiaomi MiMo.
web_search: Standard DeepSeek search with automatic query planning, source verification, and cited results.
web_search_fast: Fast search for time-sensitive queries; concise answers after 1–2 searches.
web_search_deep: Deep search that breaks queries into sub-queries, cross-verifies, and synthesizes comprehensive cited answers.
fetch_page: Fetches and extracts content from URLs, converting HTML/JSON to text with SSRF protection.
mimo_search / raw retrieval: Raw web retrieval similar to Tavily, returning structured source lists and summaries without further orchestration.
health: Checks API keys and search/fetch functionality.
Also supports location-aware searching, automatic fallback from DeepSeek to MiMo, and configuration of API keys, models, timeouts, and output lengths.
Provides web search integration with Xiaomi's MiMo API, enabling raw search results with structured sources, summaries, location-based customization, and fallback search support.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@deepseek-search-mcpWhat are the latest developments in quantum computing?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

多后端联网搜索 MCP 服务器:DeepSeek V4-Flash 全自动搜索 + 小米 MiMo 原始检索 + fetch_page 来源验证,带自动降级链与位置定制化搜索。
零依赖:纯 Python 标准库(≥3.9),无第三方包
协议自实现:stdio + JSON-RPC 2.0,兼容 Claude Desktop / Codex / Cherry Studio / Hermes 等客户端
自动降级:

工具
工具 | 模式 | 用途 | 耗时 |
| DeepSeek 全自动 | 日常查询、新闻、事实确认 | 30–60s |
| 快速 | 时效敏感的快查 | 3–8s |
| 深搜 | 事实核查、调研报告(子查询拆解 + 交叉核验) | 3–10 分钟 |
| raw 检索 | 类似 Tavily:结构化来源列表 + 摘要,不编排 | 20–40s |
| 基础 | 抓取 URL 验证来源真实内容 | 1–10s |
| 诊断 | 验证各后端与 fetch 链路 | 30–60s |
参数
location(三个搜索工具通用,可选):{"country":"中国","region":"湖北","city":"武汉"}或"湖北省武汉市"/"Wuhan, Hubei, China"。MiMo 映射user_location(实测显著提升本地结果),DeepSeek 注入查询上下文。web_search_deep的enrich_mimo(可选,默认 false):每路子查询额外注入 MiMo raw 结果作为补充来源,DeepSeek 定"准确性"、MiMo 补"覆盖面"。mimo_search的fast/max_keyword/limit(可选):控制检索成本(默认 5/5,fast 减半)。fetch_page的max_chars(可选,默认 20000):提取文本上限。

MCP 客户端接入
以 Claude Desktop 的 claude_desktop_config.json 为例:
{
"mcpServers": {
"deepseek-search": {
"command": "python",
"args": ["/absolute/path/to/deepseek_web_search_mcp.py"],
"env": {
"DEEPSEEK_API_KEY": "sk-...",
"MIMO_API_KEY": "sk-...",
"BACKEND": "auto"
}
}
}
}超时:标准模式 30–60s、深搜最长 10 分钟,客户端侧超时需配置足够长(opencode 为
experimental.mcp_timeout,单位毫秒)。
开发与测试
mcp_search/ # models / providers / fetch / server
tests/ # 99 个用例:单元(mock)+ 集成(本地 HTTP)+ stdio 端到端
mcp_client.py # 通用 MCP stdio 客户端,可调任意工具# 全量测试(配置任一 API Key 后自动包含真实搜索用例)
python -m unittest discover -s tests -p "test_*.py"
# 手动调用示例
python mcp_client.py --cmd "python" --args "deepseek_web_search_mcp.py" \
--tool mimo_search --params-file params.json \
--env "MIMO_API_KEY=sk-..." --env "BACKEND=auto" --timeout 600可靠性设计:网络错误/5xx/429/空结果自动重试;深搜规划失败自动回退默认子查询拆解、综合失败降级为结果汇总;断连自动走降级链。详见 TESTING.md。
已知限制
DeepSeek Responses API 仅支持
deepseek-v4-flash;MiMo 联网搜索需mimo-v2.5系列并在控制台启用联网插件(启停有约 5 分钟缓存期)。MiMo 请求显式禁用 thinking(默认开启时偶发返回空 content)。
fetch_page无法提取 JS 动态渲染页(SPA)正文,返回明确提示;SSRF 防护默认拒绝内网地址。mimo_search的答案摘要可能被截断(finish_reason: length),需更长输出请调大MIMO_MAX_OUTPUT。notifications/initialized无响应,客户端不能同步等待。
