概要

What is OneSearch MCP Server?

A Model Context Protocol (MCP) server that integrates with multiple search providers for web search, local browser search, URL discovery, and scraping capabilities using agent-browser. It is designed for developers building AI agents that need to search and extract web content via MCP tools.

How to use OneSearch MCP Server?

Install via npm (npx -y one-search-mcp) or Docker, then configure the search provider and optional API keys via environment variables. Use the exposed tools (one_search, one_scrape, one_map, one_extract) from any MCP client.

Key features of OneSearch MCP Server

  • Supports multiple search engines: SearXNG, Tavily, DuckDuckGo, Bing, Google, Zhipu, Exa, Bocha, and local browser search.
  • Local browser-based search (free, no API keys) using agent-browser with automatic Chromium detection.
  • Tools include: one_search, one_scrape, one_map, and one_extract.
  • Docker image with pre-installed Chromium for zero-setup deployment.
  • one_scrape supports multiple output formats: markdown, HTML, rawHtml, links, screenshot, full-page screenshot.

Use cases of OneSearch MCP Server

  • Perform web searches from an AI agent using a variety of providers with or without API keys.
  • Scrape a single page and return content in markdown, HTML, or screenshot format with optional pre-scrape actions.
  • Discover all URLs from a starting page (link discovery) via one_map.
  • Preprocess content from multiple URLs into clean text blocks for downstream LLM analysis.

よくある質問

1

What search providers are supported?

The server supports `searxng`, `duckduckgo`, `bing`, `tavily`, `google`, `zhipu`, `exa`, `bocha`, and `local` (browser-based). Default is `local`.

2

Do I need an API key?

It depends on the provider: `local` and `duckduckgo` require no API key; `searxng` requires a self-hosted URL; `bing`, `tavily`, `google`, `zhipu`, `exa`, and `bocha` require an API key.

3

What browsers are required for local search?

A Chromium-based browser (Google Chrome, Microsoft Edge, Chromium, or Google Chrome Canary) is required. The server auto‑detects installed browsers; otherwise, you can install Chromium via `npx agent-browser install`.

4

Can I run OneSearch MCP Server in Docker?

Yes. Docker images are available from GitHub Container Registry and Docker Hub, with Chromium pre‑installed. See the configuration example for Claude Desktop.

5

How do I migrate from v1.1.0 or earlier?

Remove Firecrawl environment variables, install a Chromium browser, and update to the latest version with `npm install -g one-search-mcp@latest`. Firecrawl has been replaced by agent-browser for local operations.
