MCP tool schema bloat is a hidden token cost: every enabled MCP server contributes tool definitions to the context at session start, and verbose search results compound the problem. Structured search APIs that return compact JSON instead of full web pages can cut search-related token usage by 90%+.
Top Pick
Scavio wins for token reduction with structured JSON responses averaging 200-400 tokens per search result vs 2,000-5,000 tokens for full-page fetches.
