## Description

MCP-Sage provides tools for sending prompts to Gemini 2.5 Pro with full context from specified files and directories. It implements two key tools: 'second-opinion' for getting alternative perspectives on code with complete file context, and 'expert-review' for receiving code improvement suggestions formatted as SEARCH/REPLACE blocks. Built to complement Claude Code's limited context window, this TypeScript implementation handles file packing, token counting, and gitignore-aware recursive directory traversal, making it particularly valuable for developers seeking second opinions or detailed code reviews on complex codebases.
