Agent Infra Search MCP Server: Setup for Claude Code, Cursor and Other Apps
@agent-infra/mcp-server-searchbytedance/ui-tars-desktop/tree/HEAD/packages/agent-infra/mcp-servers/searchGives Claude, Cursor and other assistants a web search tool backed by a browser, Bing, Tavily, SearXNG or DuckDuckGo.
This small server gives Claude, Cursor and other assistants one tool, a web search that returns titles, links and text. By default it searches through a browser on your computer, and you can switch to Bing, Tavily, SearXNG or DuckDuckGo. It runs locally with npx. Your search words go to whichever provider you choose.
Good for
- Anyone whose assistant has no built-in web search
- Developers who want to choose the search engine or run SearXNG themselves
- Users of Cursor or Windsurf who want a plain search tool

Watch out for
Your search words go to a third party
Whatever the assistant searches is sent to the chosen engine or API. Use SearXNG on your own server if that matters. github.com
Keys appear in the command line if you pass them
The --api-key option puts a key in your app's config. The environment variable keeps it out of the argument list. github.com

Technical details
| Turning on read-only | The only tool is a search, so there is nothing that writes. |
|---|---|
| Talks to | The search engine or provider you choose: Google through a browser by default, or Bing, Tavily, SearXNG or DuckDuckGo |
| Sign-in and keys | No key for the default browser search. Bing and Tavily need an API key, passed with --api-key or read from BING_SEARCH_API_KEY or TAVILY_API_KEY. |
Questions
Do I need an API key?
Not for the default, which searches through a browser. Bing and Tavily need a key; SearXNG and DuckDuckGo do not.
Which search engines can it use?
Browser search (Google by default), Bing, Tavily, SearXNG and DuckDuckGo. Pick one with the provider option, and the engine option for browser search.
Is it an official ByteDance product?
It is published by ByteDance under the Agent Infra name, in the UI-TARS Desktop repository. It is not a server from a search company.
Can it change my files or accounts?
No. It has one tool that returns search results.
Why do I get no results?
The tool returns "No results found" when the provider finds nothing. If you chose Bing or Tavily, check that the key is set.
