Hex SSH

Token-efficient SSH file editing with FNV-1a hash-verified anchors for preventing stale-context corruption on remote servers.

Provides six tools for remote server file operations over SSH with hash-verified integrity. Every file read returns FNV-1a hash-annotated lines and range checksums, and edits verify those checksums before applying changes to prevent stale-context corruption. Includes normalized and deduplicated command output for minimal token usage, configurable host allowlists, path restrictions, and atomic file writes via base64 encoding.
