Unicode Normalization and Homoglyph Detector MCP Connector for Claude

This MCP server provides specialized tools to identify security threats within Unicode strings. It detects malicious homoglyph substitutions (such as Cyrillic 'а' vs Latin 'a') and flags invisible zero-width characters that are often used to bypass code reviews or text filters. Using analyze_string_security, you can perform a high-level assessment of any input string. The server also provides detect_hidden_characters to find non-printing codepoints and inspect_homoglyph_substitutions to isolate visual spoofing attempts. All detection is performed via deterministic integer codepoint comparison, ensuring reliable security analysis.
