Search1API MCP Server

[中文文档](./README_zh.md)

The official MCP server for Search1API — web search, news, crawling, and more 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 npx — no cloning required:

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