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., "@websearch-deepseek What are the latest features of React 19?"
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.
A universal MCP Server that provides a web search tool powered by DeepSeek's native web search API — no third-party search API required.
Works with Claude Code, Cursor, Continue, OpenCode, pi, and any tool that supports the MCP protocol.
🔍 DeepSeek Native Search — Uses the server-side web_search_20250305 tool, no third-party search API needed
📝 AI-Generated Answers — Returns detailed answers synthesized from full page content, not just a list of URLs
🔗 Source URLs Included — Every answer comes with original source links for verification
⚙️ Flexible Configuration — Choose model, toggle thinking mode, adjust token limits
🌐 MCP Protocol — Standard JSON-RPC over stdio, compatible with all MCP clients

"websearch-deepseek": {
"command": "npx",
"args": ["websearch-deepseek"],
"env": {
"DEEPSEEK_API_KEY": "sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"WEBSEARCH_MODEL": "deepseek-v4-flash",
"WEBSEARCH_THINKING": "enabled"
}
}
}
}Edit ~/.cursor/mcp.json:
{
"mcpServers": {
"websearch-deepseek": {
"command": "npx",
"args": ["websearch-deepseek"],
"env": {
"DEEPSEEK_API_KEY": "sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}
}
}
}Edit ~/.continue/config.json, add to mcpServers:
{
"mcpServers": [
{
"name": "websearch-deepseek",
"command": "npx",
"args": ["websearch-deepseek"],
"env": {
"DEEPSEEK_API_KEY": "sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}
}
]
}Edit ~/.pi/agent/settings.json, add to mcp:

}
}Restart your AI coding assistant and ask a question that needs real-time information. The assistant will automatically call the web_search tool when needed.
Examples:
"What's new in React 19?"
"Search for Python 3.13 release date and major updates"

Scenario | Recommended Model | Notes |
Daily search (default) |
| Fast, low cost, good quality |
Deep research |
| More detailed and accurate, slightly slower |
enabled (default): The model thinks before answering, producing higher quality results but consuming more tokens
disabled: Skips the thinking step for faster responses, suitable for simple queries
You can also use it directly from the terminal:
# Set API Key
export DEEPSEEK_API_KEY=sk-xxxxxxxxxxxxxxxx
# Search
npx websearch-deepseek search "Node.js LTS versions"
# JSON output
npx websearch-deepseek search --json "TypeScript 5.8"
# Specify model and disable thinking
npx websearch-deepseek search --model deepseek-v4-pro --no-thinking "Rust latest version"## Node.js Latest LTS Versions
