x16-emulator-MCP is a Python [Model Context Protocol (MCP)](https://modelcontextprotocol.io) server that lets an AI application boot, drive, and interrogate a real [Commander X16](https://github.com/X16Community) emulator through its headless `-debugstdio` debugger. The agent works the way a person would at a debugger: set breakpoints and memory watchpoints, run, read registers, memory, and VRAM, evaluate conditions, and look at the screen.

Ask an AI agent something like:

> A routine is clobbering zero-page `$70` and I don't know which one. Put a write watchpoint on it, run, and tell me what writes there.

A moment later the answer comes back in the tool-result pane: `$0070 written as $aa by the instruction at $0502`. Catching the program counter behind a stray write is the loop the project is built for.

x16-emulator-MCP drives a [fork of the Commander X16 emulator](https://github.com/acscpt/x16-emulator) that carries the headless debugger protocol it speaks. Install and configure the emulator before using the server; the [installation guide](docs/installation.md) walks through it.

## What the AI agent can do with it

The server exposes the debugger as a set of typed tools; the [tool reference](docs/tool-reference.md) documents each with a worked example.

- Boot a headless X16 session against a ROM, optionally loading a PRG at the BASIC prompt, and keep several independent sessions open at once, each addressed by a session id.

- Set execution breakpoints and read or write…
