Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server One Search MCP for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "one-search": { "command": "npx", "args": [ "-y", "one-search-mcp" ], "env": { "SEARCH_API_URL": "your-value", "SEARCH_API_KEY": "your-value", "YDC_API_KEY": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For SEARCH_API_KEY, YDC_API_KEY, SEARCH_API_URL, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the One Search MCP tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

Common questions

Is One Search MCP safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SEARCH_API_KEY, YDC_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 4 months ago, and the latest version (1.2.4) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

🚀 OneSearch MCP Server: Web Search, URL Discovery, Scraper & Content Prep

A Model Context Protocol (MCP) server implementation that integrates with multiple search providers for web search, local browser search, URL discovery, and scraping capabilities with agent-browser.

Features

Web search, scrape, discover URLs, and preprocess content from websites.
Support multiple search engines and web scrapers: SearXNG, Tavily, DuckDuckGo, Bing, Google, Zhipu (智谱), Exa, Bocha (博查), You.com, etc.
Local web search (browser search), support multiple search engines: Bing, Google, Baidu, Sogou, etc.
Use agent-browser for browser automation.
Free, no API keys required.
Enabled tools: one_search, one_scrape, one_map, one_extract

Current Tool Surface

one_search
Returns search results from the configured provider.
one_map
Discovers links from a starting URL by loading the page in the browser and extracting links from its HTML.
Supported input fields: url, search, includeSubdomains, limit.
This is not a sitemap crawler; removed fields such as ignoreSitemap and sitemapOnly are rejected at the schema boundary.
one_scrape
Scrapes one page and returns content selected by formats.
Supported input fields: url, formats, waitFor, timeout, skipTlsVerification, allowExecuteJavascript, actions.
Supported formats: markdown, html, rawHtml, links, screenshot, screenshot@fullPage.
Supported bounded pre-scrape actions: wait, click, write, press, scroll.
Advanced pre-scrape action: executeJavascript. If actions contains executeJavascript, you must set allowExecuteJavascript: true.
actions run serially before content capture and fail fast on the first action error.
Removed fields such as onlyMainContent, extract, and location are rejected at the schema boundary.
one_extract
Accepts only urls and returns preprocessed text blocks for downstream tools or models.

Migration from v1.1.0 and Earlier

Breaking Changes in v1.1.0:

Firecrawl Removed: The Firecrawl integration has been removed in favor of agent-browser, which provides similar functionality without requiring external API services.
New Browser Requirement: You must install Chromium browser (see Prerequisites section).
Environment Variables: FIRECRAWL_API_URL and FIRECRAWL_API_KEY are no longer used.

What Changed:

one_scrape and one_map now use agent-browser instead of Firecrawl
one_extract now preprocesses multi-URL page content for downstream analysis instead of performing built-in LLM extraction
All browser-based operations are now handled locally, providing better privacy and no API costs

Migration Steps:

Install Chromium browser (see Prerequisites)
Remove FIRECRAWL_API_URL and FIRECRAWL_API_KEY from your environment variables
Update to the latest version: npm install -g one-search-mcp@latest

Prerequisites

Browser Requirement: This server uses agent-browser for web scraping and local search, which requires a Chromium-based browser.

Good News: The server will automatically detect and use browsers already installed on your system:

✅ Google Chrome
✅ Microsoft Edge
✅ Chromium
✅ Google Chrome Canary

If you don't have any of these browsers installed, you can:

# Option 1: Install Google Chrome (Recommended)

Download from: https://www.google.com/chrome/

Option 2: Install Microsoft Edge

Download from: https://www.microsoft.com/edge

Option 3: Install Chromium via agent-browser

npx agent-browser install

Option 4: Install Chromium directly

Download from: https://www.chromium.org/getting-involved/download-chromium/

Installation

Using Claude Code CLI (Recommended)

# Add to Claude Code with default settings (local search)

claude mcp add one-search-mcp -- npx -y one-search-mcp

Add with custom search provider (e.g., SearXNG)

claude mcp add one-search-mcp -e SEARCH_PROVIDER=searxng -e SEARCH_API_URL=http://127.0.0.1:8080 -- npx -y one-search-mcp

Add with Tavily API

claude mcp add one-search-mcp -e SEARCH_PROVIDER=tavily -e SEARCH_API_KEY=your_api_key -- npx -y one-search-mcp

Manual Installation

# Install globally (Optional)

npm install -g one-search-mcp

Or run directly with npx

npx -y one-search-mcp

Local Debugging with MCP Inspector

Use the official MCP Inspector to interactively test tools, resources, and prompts against this server during local development.

# Inspect the TypeScript source entrypoint

npm run inspector

Inspect the built server entrypoint

npm run inspector:build

Example with explicit environment variables

ALLOW_PRIVATE_NETWORK=true SEARCH_PROVIDER=local npm run inspector

Using Docker

Docker image includes all dependencies (Chromium browser) pre-installed, no additional setup required.

Pull the image:

# From GitHub Container Registry

docker pull ghcr.io/yokingma/one-search-mcp:latest

Or from Docker Hub

docker pull zacma/one-search-mcp:latest

Configure with Claude Desktop:

"mcpServers": { "one-search-mcp": { "command": "docker", "args": ["run", "-i", "--rm", "ghcr.io/yokingma/one-search-mcp:latest"], "env": { "SEARCH_PROVIDER": "local" } } } }

With custom search provider:

"mcpServers": { "one-search-mcp": { "command": "docker", "args": [ "run", "-i", "--rm", "-e", "SEARCH_PROVIDER=tavily", "-e", "SEARCH_API_KEY=your_api_key", "ghcr.io/yokingma/one-search-mcp:latest" ] } } }

Environment Variables

Search Provider

SEARCH_PROVIDER (Optional): The search provider to use, supports searxng, duckduckgo, bing, tavily, google, zhipu, exa, bocha, ydc, local, default is local.
SEARCH_API_URL (Optional): The URL of the SearxNG API, or Google Custom Search Engine ID for google.
SEARCH_API_KEY (Optional): The API key for the search provider, required for tavily, bing, google, zhipu, exa, bocha.
YDC_API_KEY (Optional): You.com API key for SEARCH_PROVIDER=ydc.

// supported search providers

Browser Network Security

ALLOW_PRIVATE_NETWORK (Optional): Set to true to allow browser-backed tools (one_scrape, one_map, one_extract) to access private, loopback, and link-local network targets. Defaults to false.

Use ALLOW_PRIVATE_NETWORK=true only in trusted deployments. When enabled, prompt injection or untrusted tool inputs can make the MCP process fetch internal services that are otherwise blocked by default.
