Repo Prompt automates assembling the perfect context for your project by helping AI models understand your codebase without wasting tokens on irrelevant code. Its Context Builder analyzes your project to select necessary files and functions, creating dense context that fits model limits. It works with existing AI subscriptions like Claude MAX, ChatGPT Plus, and Gemini, incurring no extra API costs. The MCP server transforms Repo Prompt into a backend for Claude Code, Cursor, and Codex, providing them with exclusive context analysis and discovery capabilities.
