Thanks for the interest. I wrote GhidrAssistMCP and the original GhidrAssist plugin which work hand-in-hand because I find they improve my RE workflow. They're not immune from hallucinations because the underlying models are not. However, they are fairly rare and I have had very reliable results with both Claude and ChatGPT. When used together, GhidrAssist+GhidrAssistMCP have been able to do some impressive analysis tasks.

If you're just getting back in the saddle, you might want to give both a try. In particular, GhidrAssist's "Explain Function" tool is really helpful at quickly summarizing code and reducing the mental overhead of making sense of large binaries.

I can't comment on MCP use specifically but I can comment on using an LLM while reversing. I use a local instance of whatever ends up being SOTA for local reasoning LLMs at 30B-70B params quantized to 4-6b. I feed it decompiled code to identify functions that are 'tedious' to reverse engineer. I recently reversed a binary that was compiled with soft float and had no symbols or strings. A lot of those functions end up being a ton of bit-twiddling. While I reversed the business logic I had the reasoning model identify the soft float functions with very minimal prompting. It did quite well on those!

I also tried to have it automatically build some structs from code showing the access patterns, and it failed miserably on that task. Likely a larger model (o3 or opus) would do better here.

I personally don't think letting an LLM do large parts of the reversing would be useful to me as I build up a lot of my mental model of the system during the process, so I'd be missing out on that. But for handling annoying bits of code I'd likely just forego otherwise? Go ham!

GhidrAssistMCP features:

- several additional tools (like get_class_info, search_classes, etc),

- it has GUI config and logging,

- and it does not rely on an external Python bridge to host the MCP Server - it's monolithic (using the official MCP Java SDK).
