c64bridge vs lean-ctx
c64bridge: C64 Bridge is an MCP server for controlling and working with a Commodore 64 from an AI client. It lets you run programs, read and write memory, render graphics, and play sound on a real Commodore 64 Ultimate or Ultimate 64. You can also switch to a VICE emulator session at any time.; 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.
