Zume Editor ships beta with MCP binary analysis for Claude

The pitch behind Zume Editor is consolidation. Its developer describes everyday work as a sprawl of separate viewers, HEX editors, Git clients, SFTP, database clients, and diff tools that start slowly and choke on large files. Zume's answer is a native app that avoids heavy runtimes, opens instantly, and is built to handle files of several GB without loading them fully into memory — the author says 10GB-class files have been measured. The same undo operation and UI carry across code editing, HEX editing, Git, and diff/merge.

The distinctive piece is how the binary analysis is exposed. Rather than a standalone reverse-engineering suite, Zume publishes its engines as an MCP server, so an AI agent such as Claude can invoke them as tools: structure parsing for PE/ELF/Mach-O, Capstone-based disassembly across x86, x64, ARM, Thumb, and AArch64, cross-reference and function-boundary recovery, Ghidra-linked decompilation, Objective-C/Swift interface recovery, and YARA scanning. A user can ask in natural language, for example, to list a file's imported functions or show where GetProcAddress is called.

The safety framing is deliberate: analysis is static only, the target is never run, everything stays local, and access scope can be constrained. The same engines are also usable manually from the editor's Code menu, so a user can jump from a code line to the matching HEX offset and disassembly and then patch in the same app. The beta is free until March 31, 2027, after which the app stops launching; a subscription is planned for the full release, with code signing for the portable ZIP still on the to-do list.
