What it is

hexvero is an MIT-licensed, Node-only MCP server that gives a coding agent a static first look at binaries and app bundles without executing them. The author (@44errrr) built it as a low-context alternative to an established reverse-engineering MCP server, which they say has a 509,696-token tool catalog. hexvero's is 3,043 tokens.

How it works

The page gives only a high-level description:

• Parsers have zero dependencies.
• Every finding is marked confirmed or inferred, with file and line.
• Lists are paged against a byte budget, which keeps results small.
• radare2, rizin or Ghidra can be plugged in when disassembly is needed.

What to do

Measured comparisons the author reports, beyond the headline catalog size:

The page does not say which tool produced the "before" figures. It says the method, numbers and scripts are in the repo, so you can reproduce them against your own targets.

To install and register with your agent clients:

npx hexvero setup --apply

The page says this registers hexvero with Claude Code, Cursor, Codex and 15 more clients. It runs a setup that modifies client configs, so read the repo first if that matters in your environment.

Caveats

• The author states the larger tool does much more: dynamic analysis, devices and firmware. hexvero is positioned as triage before that, not a replacement.
• The numbers are the author's own, from a single post. The page carries no independent verification, and it does not name the competing server.
• The page only describes static analysis. Anything needing execution or deep disassembly depends on the optional radare2, rizin or Ghidra backends.
