New: Agent Access for MCP. Enable Agent Access in Settings to let compatible local AI coding agents such as Codex and Claude use Hexgeist as a structured binary workbench. Instead of chaining together file, xxd, strings, cmp, and one-off scripts, an agent can inspect formats and byte ranges, search exact bytes, text, or integers, compare binaries with alignment-aware differences, extract detected resources, and save range-linked findings through one consistent interface. Hexgeist keeps the workflow local and deliberate: it starts an authenticated MCP server that listens only on the local loopback interface, accesses only folders you grant, and requires edits to be staged for review before commit. Agent Access is off by default and runs only while Hexgeist is open. Also new: Spectral Map and Bit Lab provide persistent whole-file context and precise, undoable byte editing. Editing, analysis refresh, and undo/redo reliability are improved throughout the app.

The app is now much faster at recognizing what kind of file you’re actually looking at, starting with the first four bytes. If a file opens with something loud, Hexgeist should not sit there politely wondering what it is. The Lens now surfaces that kind of magic-byte identity right away while the deeper scan continues in the background. This update also adds richer file intelligence throughout the Lens: header notes, hash details, string extraction helpers, embedded resource previews, and better jump/copy actions for moving from insight to bytes without breaking your flow.
