agent-tool vs lean-ctx

agent-tool: agent-tool is a single-binary MCP tool server that provides over 50 tools for AI coding agents. It addresses common issues like tab indentation corruption, encoding breakage, and lack of reverse engineering support. With smart indentation and encoding preservation, it seamlessly replaces built-in tools.; lean-ctx: lean-ctx is an open-source MCP server designed to drastically reduce LLM token costs for AI coding tools like Claude Code, Cursor, and Copilot. It achieves this by transparently compressing CLI output and file context, offering up to 99% savings and making AI coding faster, cheaper, and more effective without changing workflows.
