C64 Bridge

Your AI Command Bridge for the Commodore 64.

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 C64 Ultimate, Ultimate 64, or U2-family cartridge. You can also switch to a VICE emulator session, so one MCP conversation can span hardware and emulation.

It is built on the official TypeScript @modelcontextprotocol/sdk and supports both stdio for local AI integration and an optional HTTP bridge for manual inspection.

C64 Bridge is listed in the Official MCP Registry.
