RetroArch MCP server

Let your AI peek into a running retro game, read its memory, save states, and take screenshots.

This is a small helper that connects your AI assistant to RetroArch, the popular app for playing old console games on your computer. Once it is set up, you can ask your AI things about the game you are playing, like what is in memory right now or what game is loaded. It is handy for people who enjoy retro games and like poking around under the hood.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to another app. This one connects your AI to RetroArch, the emulator running on your own computer. So when you ask a question about your game, the AI can actually look at RetroArch and answer based on what is really happening there.

What this MCP server does

You ask your AI something about the game running in RetroArch. The AI sends that request to this helper program on your computer. The helper talks to RetroArch over a small network channel that RetroArch already has built in. RetroArch answers back, and the helper passes the answer to your AI. Then your AI tells you the result in plain words, like the game title, a chunk of memory, or confirmation that it paused the game.

Flow diagram: you ask your AI “What game is running in RetroArch right now?”, on your own computer the RetroArch MCP server works with retroArch, and you get back answers in your chat.

“Read 16 bytes of memory starting at address 0x0000 in the current game.”
“Pause the game and take a screenshot.”
“Save a state to the current slot and show me a message that says checkpoint saved.”

What it gives back to you

You get answers in the chat: the game title, the system, a CRC32 code, or a list of bytes from memory. It can also confirm actions like pausing, resetting, saving a state, or taking a screenshot.
