Documentation

mcp-deepseek-search

An Model Context Protocol server that exposes DeepSeek's web Search and Fetch tools to any MCP client — Claude Desktop, Claude Code, Cursor, Cline, ZCode, and more.

Works with any LLM: the search runs on DeepSeek's own search engine, but the results are returned to your existing model as ordinary tool output.

Features

deepseek_search — web search backed by DeepSeek's search engine, with two quality signals per result:
- rerank_score (0–3): relevance; ≥ 1.5 = highly relevant
- authority (0–4, -1 unknown): source authority; ≥ 3 = highly authoritative
deepseek_fetch — fetch a single page and get its main content as Markdown
Powerful query syntax: site:, -site:, -term, "exact phrase", -"phrase", lang:zh,en, after:YYYY-MM-DD, before:YYYY-MM-DD
Built-in throttling (stays under the 5 QPS account limit) and automatic retry on 408/429/5xx
Response-size friendly: summaries by default, full page text only on request

Setup

Get an API key at platform.deepseek.com (web tools are billed at ¥5 per 1,000 successful calls, charged to your DeepSeek account — failed calls and empty results are not billed).
Add the server to your MCP client config:

Claude Desktop / Cursor / Cline / most clients

{
  "mcpServers": {
    "deepseek-web": {
      "command": "npx",
      "args": ["-y", "mcp-deepseek-search"],
      "env": {
        "DEEPSEEK_API_KEY": "sk-your-key-here"
      }
    }
  }
}

ZCode

Add the same mcpServers block to your ZCode MCP settings (Settings → MCP → Add server).

From source

git clone https://github.com/Matthewyin/deepseek-mcp
cd deepseek-mcp && npm install && npm run build
node dist/index.js   # stdio MCP server

Tools

`deepseek_search`

Parameter	Type	Required	Description
`query`	string	yes	1–128 chars; supports the search syntax above
`count`	integer	no	1–50 results, default 10 (does not affect billing)
`ori_question`	string	no	The user's original question — improves intent matching when the query was rewritten
`localization`	string	no	User IP to localize results (pass only with consent)
`need_content`	boolean	no	Include full page text per result (each truncated at 8,000 chars). Default `false`

Each result includes title, url, snippet (short, for display), summary (long, for feeding to a model), rerank_score, authority, site_name, date, and optionally content.

`deepseek_fetch`

Parameter	Type	Required	Description
`url`	string	yes	Plain `http(s)` URL, max 8,192 chars, no embedded credentials

Returns title + Markdown content (truncated at 30,000 chars).

Example

Ask your agent: "用 deepseek_search 搜一下最近一周关于 MCP 的大新闻，挑权威来源，再用 deepseek_fetch 读全文总结" — or in English: "Search for recent DeepSeek news, keep only results with authority ≥ 3, fetch the top one and summarize."

Notes & limits

Rate limit is 5 QPS per DeepSeek account (shared across all your API keys); the server throttles automatically.
HTTP 402 means your DeepSeek balance ran out; 401 means the key is invalid.
Page content depends on the target site's availability and access policy.
This is an unofficial community wrapper; not affiliated with DeepSeek.

Development

npm install
npm run build
DEEPSEEK_API_KEY=sk-... npm test   # end-to-end test against the real API

Releases are automated via GitHub Actions: pushing a v* tag publishes to npm and the official MCP Registry.
