agent-tool vs letta

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.; letta: Letta is a powerful platform for building stateful AI agents equipped with advanced memory, enabling them to learn and self-improve over time. It provides both a command-line interface for local agent execution and a comprehensive API with Python and TypeScript SDKs for seamless integration into applications.
