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.
- Every MCP request — including tool discovery (
initialize,tools/list) — requires a credential. Unauthenticated requests draw the OAuth challenge, which is how clients trigger sign-in; pre-connect inspection is served by the static server card instead.
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 |
