6502MCP

[John Kennedy]

If you are tinking with 6502 code, and have access to LLMs like Claude or CODEX, you might find this MCP Sever handy. It _should_ help you write 6502 by automatically testing it.

Great!

How does that work?

[John Kennedy]

It's a virtual 6502 machine that provides specific commends e.g. "execute code" in the form an LLM can use (that's all an MCP Server is - a list of commands in a specific format). It means that the LLM can test code rather than just doing the usual LLM thing of making up answer that looks like it will be right (because that's all what today's AIs do - respond with an answer that looks like it could be answer). This means that if you ask your LLM to write for 6502 to add two numbers, the LLM will have a guess (as usual) but then actually test it.
