lean-ctx
Reduce AI coding costs by 99% — MCP Server + Shell Hook for Cursor, Claude Code, Copilot, Windsurf, Gemini CLI & 24 tools. Single Rust binary, zero telemetry.
- Generate features in large monorepos without sending entire codebase
- Refactor isolated modules while keeping API surface in context
- Debug issues by limiting context to affected dependency chains
Dramatically reduces token spend in AI-assisted coding by filtering context to relevant files and dependencies. Cuts API costs while maintaining code quality in large codebases.
Engineering teams using Claude, Cursor, Copilot, or other AI coding tools who need to control LLM context window usage without sacrificing code generation accuracy.
