Professional Fingerprint MCP
ShapeLex v0.6.0 turns the original prototype into a deterministic, local-first retrieval system for long AI coding sessions.
Highlights
- Deterministic Unicode-aware lexical fingerprints, rolling hashes, O(n) winnowing, and offset voting.
- Exact matches require both raw UTF-8 byte equality and a full SHA-256 verification.
- Recognition of exact, relocated, reordered, and closely related text.
- English and Spanish critical-difference protection for negations, numbers, dates, operators, destructive verbs, and instructions.
- Lazy, bounded, memory-only fingerprint index with suppression limits and LRU eviction.
- Transactional store v2 with migration, revisions, locking, atomic writes, and content-addressed sources.
- Compact match metadata through the existing MCP tools, without expanding the public tool surface.
- Node.js 22+ support and expanded property, acceptance, torture, performance, mutation, packaging, platform, and security verification.
