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:

MethodFormat
OAuth 2.1Connect to https://mcp.search1api.com/mcp without a key and follow the client sign-in flow
Authorization HeaderAuthorization: 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.
