How does the tool handle emojis?

The `analyze_encoding_impact` tool detects if any character falls outside the GSM-7 set, triggering a UCS-2 encoding warning and calculating the increased segment count.

Can I check for legal compliance?

Yes, use `validate_regulatory_compliance` to verify that your message contains required sender identification and opt-out instructions like "STOP" or "HELP".

Does it help with link shortening?

Absolutely. The `calculate_link_optimization` tool calculates exactly how many characters you save by using a shortened URL compared to the original.

This MCP server provides a powerful engine to audit SMS campaigns. Use analyze_encoding_impact to detect if emojis or special characters will force a switch from GSM-7 to UCS-2 encoding, which increases segment costs. The validate_regulatory_compliance tool ensures your messages include mandatory opt-out keywords like "STOP" and "HELP", as well as proper sender identification. Additionally, use calculate_link_optimization to determine the character savings achieved by using shortened URLs in your campaigns.
