What can you do with Search1 API MCP?

Web search with source filtering — Ask for search results from Google, Bing, Reddit, GitHub, YouTube, or arXiv using search, with options to include or exclude specific sites and set a time range.
News article discovery — Use news to find recent articles across Google, Bing, DuckDuckGo, Yahoo, or Hacker News, optionally crawling top results for full content.
Page content extraction — Pass a URL to crawl to retrieve the full text of a webpage when search snippets aren't enough.
Sitemap and link discovery — Call sitemap on a URL to get all related links from that page.
Trending topics lookup — Use trending to fetch current hot topics from GitHub or Hacker News.

Documentation

Search1API MCP Server

中文文档

The official MCP server for Search1API — web search, news, page retrieval, sitemap discovery, and trending topics in one API.

Authentication

OAuth-aware clients can connect to the Remote MCP URL directly, then sign in and approve access in the browser.
Existing integrations can continue to use an API key from the Search1API dashboard.

Quick Start (Remote MCP)

No installation required. Configure your MCP client with the remote URL. Use OAuth when the client supports it, or provide an API key.

Authentication

Three methods are supported — use whichever your client supports:

Method	Format
OAuth 2.1	Connect to `https://mcp.search1api.com/mcp` without a key and follow the client sign-in flow
Authorization Header	`Authorization: Bearer YOUR_SEARCH1API_KEY`
URL Query Parameter (legacy)	`https://mcp.search1api.com/mcp?apiKey=YOUR_SEARCH1API_KEY`

Prefer OAuth or the Authorization header. Query-parameter credentials can be exposed in URLs, logs, and shell history.

Agent Skill

The Agent Skill has moved to search1api-cli. Install it with:

npm install -g search1api-cli
npx skills add superagents-lab/search1api-cli

Local Mode (stdio)

If you prefer to run the server locally, use Node.js 20 or newer with npx — no cloning required:

{
  "mcpServers": {
    "search1api": {
      "command": "npx",
      "args": ["-y", "search1api-mcp"],
      "env": {
        "SEARCH1API_KEY": "YOUR_SEARCH1API_KEY"
      }
    }
  }
}

For self-hosted HTTP deployments behind a proxy, add any internal hostnames that reach the Node.js process to the comma-separated MCP_ALLOWED_HOSTS environment variable. mcp.search1api.com and localhost addresses are allowed by default. Browser-based clients that send an Origin header must also have their trusted origin hostnames added to the comma-separated MCP_ALLOWED_ORIGINS variable. Requests from server-side MCP clients normally omit Origin and do not require an entry.
