OmniGlyph

A local MCP server that gives Claude deterministic Unicode and domain term lookups before it reasons over text. Exposes tools like lookup_glyph, scan_unicode_security, and scan_code_symbols to catch homoglyphs, zero-width characters, and Bidi controls in code or generated output. You can mount private Lexicon Packs for company-specific SKUs or vocabulary, then use validate_output_terms to block unknown terms before they reach customers or downstream systems. Built on SQLite with UnicodeData and Unihan sources. Reach for this when you need guardrails around symbol confusion, OCR cleanup, or enterprise output validation where probabilistic models aren't enough.
