OpenWebUI supports external search tools through its tool/function system and MCP integration. Adding a search API gives your OpenWebUI instance access to live web data, grounding local or cloud LLM responses with current information. We ranked five search APIs by OpenWebUI compatibility, setup ease, and result quality.
Scavio integrates with OpenWebUI via MCP server or REST API tool function. The MCP server at mcp.scavio.dev/mcp provides the simplest setup, while a custom tool function gives more control over output formatting.

Why Scavio Wins
- MCP server integration means OpenWebUI users add search with a configuration change, no custom tool code needed.
- Six-platform coverage gives OpenWebUI users access to YouTube, Amazon, and Reddit data alongside web search, which no other provider offers in one integration.
- SearXNG is the best free option for privacy-maximalist OpenWebUI setups that can accept the hosting overhead.
- Tavily has more community OpenWebUI tools available and a larger free tier, making it a good choice for web-only OpenWebUI search.
- REST API fallback means OpenWebUI instances without MCP support can still integrate Scavio through a custom tool function.
