AI agents (LangChain, CrewAI, AutoGPT, Claude Code) hallucinate when reasoning from stale training data. Search grounding connects the agent to current web data, reducing hallucination and enabling tasks that require real-time information like price checking, news monitoring, and documentation lookup.
Top Pick
Scavio wins for agent grounding with native MCP/LangChain/CrewAI support, five-platform coverage for diverse grounding needs, and structured JSON that maximizes grounding signal per token.

- Five platforms provide grounding for diverse query types: Google for facts, Reddit for opinions, Amazon for prices, YouTube for tutorials.
