Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Give Claude live access to the web. This plugin adds You.com search, full-page content extraction, and cited multi-source research to Claude, so answers about fast-moving libraries, APIs, tools, and markets come from current sources instead of stale training data. Every answer cites the pages it read.

What you can do

  • Search the live web: find current information, news, pricing, and facts, then read the actual pages before answering.
  • Pull web data into your work: extract clean Markdown, HTML, or metadata from any public URL, including docs pages, tables, and reports.
  • Code with current docs: look up the latest library docs, API references, changelogs, breaking changes, package versions, and fixes for error messages while you build.
  • Research with citations: compare frameworks, evaluate tools and vendors, or produce a deep-dive report synthesized from many sources.
  • Research companies and markets: get stock prices, earnings, and company financials.
  • Build with You.com: find the right You.com API, MCP server, or SDK path for your own app or agent.

Example prompts:

What changed in the latest Next.js release, and does it break my middleware?
Find the current docs for this error message and suggest a fix.
Compare the top three Python vector databases on pricing and features, with sources.
Read https://example.com/pricing and summarize the plan limits as a table.
Research NVIDIA's latest earnings and cite the numbers.

Install in Claude Code

/plugin marketplace add youdotcom-oss/agent-skills
/plugin install you@you-com

Basic web search works without an account through the free MCP profile. For full search, content extraction, research, and finance, sign in with OAuth when prompted or set an API key from [you.com/platform/api-keys](https://you.com/platform/api-keys
