Why Scavio Wins
- MCP server at mcp.scavio.dev/mcp enables zero-code agent integration. Claude Code, Cursor, opencode, and any MCP-compatible agent gains search capability with one config line. No SDK, no HTTP wrapper needed.
- Structured JSON output uses 600-800 tokens per search result set, vs 4,000-8,000 tokens for raw HTML. At GPT-4o input pricing, this saves $0.008-0.018 per search in LLM costs alone.
- Six-platform coverage means one search tool handles Google SERP, Amazon products, YouTube videos, Reddit discussions, TikTok content, and Walmart listings. Agents with multi-platform tools make better-grounded decisions.
- At $0.005/query with 250 free monthly, agent developers can prototype and test without payment setup. Serper offers more free queries (2,500) but is Google-only.
