Search1API MCP Server

中文文档

The official MCP server for Search1API — web search, news, crawling, and more in one API.

Get Your API Key

1. Register at Search1API
2. Get your API key from the dashboard

Quick Start (Remote MCP)

No installation required. Just configure your MCP client with the remote URL and your API key.

Authentication

Two methods are supported — use whichever your client supports:

Agent Skill

This repo also includes an Agent Skill that teaches agents how to use Search1API effectively — with decision strategies (when to search vs. crawl, how to tune parameters for different intents), multi-step workflows, and constraints.

The skill works in two modes: it prefers MCP tools when available, and falls back to bundled shell scripts for agents that don't support MCP (e.g. OpenClaw).

npx skills add fatwang2/search1api-mcp

Even if you're already using the MCP server above, the skill adds a strategy layer that helps agents make smarter decisions — like adjusting max_results based on research depth, choosing the right search_service for a query, or running a multi-step search → crawl → synthesize workflow. See the skills/ directory for details.

Quick start — copy and send this to your Agent:

I want to use Search1API for web search and content retrieval. Install the skill (npx skills add fatwang2/search1api-mcp), help me complete the setup, and run a quick test to verify it works.

Update skills:

Update my installed skills to the latest version: npx skills update

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"
      }
    }
  }
}
