Add You.com to Claude Code

Give Claude Code real-time web search, content extraction, and citation-backed research through the You.com MCP Server.

Quick setup

Add You.com to Claude Code (no API key)

$ claude mcp add --transport http you-com https://api.you.com/mcp

Claude Code initiates the OAuth 2.1 flow automatically — sign in with your You.com account in the browser window that opens, and you’re done. No API key, no copy-pasting tokens.

Verify the tools are loaded

Inside a Claude Code session:

$ /mcp

You should see you-com listed with you-search, you-contents, and you-research.

Try it

Search for the three latest TypeScript 5.5 features and show me code examples for each.

Skip OAuth (use an API key)

If you’d rather pass an API key directly — useful for CI, scripts, or shared dev containers:

$ claude mcp add --transport http you-com https://api.you.com/mcp \
>   --header "Authorization: Bearer <YDC_API_KEY>"

Get a key at you.com/platform.

Free tier (no account, no OAuth)

Want to try it before signing in?

$ claude mcp add --transport http you-com https://api.you.com/mcp?profile=free

Free tier gives you-search only, 100 queries per day. No signup, no auth.

Quick demo

Research the trade-offs between WebAssembly and JavaScript for performance-critical browser apps. Use citations.

Extract the content from https://modelcontextprotocol.io/specification and summarize the authentication section.

Troubleshooting

OAuth window doesn't open

Confirm Claude Code is on the latest version. Run claude --version and update if needed.

401 with API key

Check for extra spaces or smart quotes in the --header value.

Tools don't show up in /mcp

List configured servers with claude mcp list. If you-com is there but tools are missing, restart Claude Code.
