File Tools MCP Server

Claude sees Настройки - not ???? or Íàñòðîéêè. MCP server for file operations on text that isn't UTF-8. It detects the encoding from the file's bytes rather than its extension, hands the model UTF-8, and writes back in the original encoding - BOM and CRLF/LF intact, still byte-compatible with whatever legacy tool owns the file.

People who work with cp1251, cp1252 and cyrillic and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Go.
