Customer support AI agents hit a wall when the knowledge base does not cover the customer's question. Live web search fills the gap: the agent searches for current product information, known issues, or community solutions, and responds with cited sources instead of guessing.
Top Pick
Scavio wins for support agents with Google for official answers plus Reddit for community workarounds, structured results that fit support response templates, and MCP for agent framework integration.

Why Scavio Wins
- Google + Reddit covers both official documentation and community workarounds. Support agents often need the workaround, not the official answer.
- Structured results map to support response templates. Title, snippet, and URL plug directly into 'Here is how to fix this:' format.
- MCP integration means support agents on LangChain or CrewAI get search as a native tool. No custom API integration code.
- Sub-2-second response keeps live chat support responsive. The customer does not notice the search delay.
- 250 free credits/mo covers support agent development and testing before production deployment.
