A+

Encode and decode strings between Base64, Base64URL, and Hexadecimal formats with byte size calculation.

7 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides a precise utility for transforming text across multiple encoding schemes. It allows AI agents to perform reliable conversions between plain text and Base64, Base64URL (URL-safe), and Hexadecimal formats. Beyond simple conversion, the server includes functionality to calculate the exact byte size of any payload using UTF-8 encoding, which is essential for managing data limits in API requests or database storage. Using tools like encode_base64, decode_hex, or get_byte_size, agents can verify string integrity and prepare data for web-safe transmission without relying on external APIs.
