When an AI Agent attempts to generate a JSON payload containing an attachment (like sending an email via SendGrid API), it often tries to encode the Base64 string itself. This results in missing characters and corrupted files. This MCP offloads binary manipulation to the Edge V8 engine.

The Superpowers

  • Zero Data Loss: Safely handles UTF-8 buffers and converts them strictly to standard Base64, Hex, or URL-safe Base64.
  • Bidirectional Conversion: Can also decode Base64 strings back to readable JSON or raw strings.
