Context7 vs token-optimizer-mcp
Context7: Context7 is an MCP server that injects up-to-date, version-specific library documentation directly into LLM prompts. Add "use context7" to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible editor.; token-optimizer-mcp: Token Optimizer MCP is a Model Context Protocol (MCP) server designed to reduce context window usage for AI tools like Claude Code and Claude Desktop by 60-90%. It achieves this through intelligent caching, Brotli compression, and smart tool replacements, storing compressed content externally in SQLite.
