When a Martech AI Agent drafts an SMS campaign via Twilio or Zenvia, the LLM will often include emojis (🚀) or smart quotes (” instead of "). This instantly breaks the standard 160-character GSM-7 encoding, reducing the limit to 70 characters and splitting the message into 3 parts. The client ends up paying 3x more for the campaign. This MCP solves that perfectly.

The Superpowers

  • Emoji Eradication: Safely strips all emojis and zero-width characters using aggressive regular expressions.
  • Unicode Transliteration: Converts complex accents and symbols into safe 7-bit ASCII (GSM-7) to guarantee maximum character limits per message segment.
