IBlueText

iBlueText MCP server

Text your customers from your AI assistant. iBlueText sends real blue-bubble iMessage, SMS and WhatsApp from a business's own dedicated phone number, and checks which numbers are iPhones. This MCP server gives Claude, ChatGPT, Cursor and any other MCP client native tools for it: send one message or a whole campaign, read replies and lead scores, manage contacts, sequences and quick answers, and run iPhone / WhatsApp lookups.

There are two ways to connect.

1. Hosted (ChatGPT, Claude, no API key)

Server URL: https://ibluetext.com/mcp (Streamable HTTP, OAuth sign-in)

• Claude: Settings › Connectors › Add custom connector › paste the URL › Connect, then sign in to iBlueText and click Allow.
• ChatGPT: Settings › Apps (Developer mode) › create an app with the URL, then sign in and Allow.
• Any remote-MCP client: use the URL; the client discovers OAuth from /.well-known/oauth-protected-resource.

22 tools with plain verb names (send_message, create_campaign, check_iphones, list_conversations, ...). Full list and example prompts: https://ibluetext.com/ai-assistants

2. Local package with an API key (developers, 30 tools)

1. Create an API key at https://ibluetext.com/portal/integrations.php
2. Add this to your MCP client config (for example Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "ibluetext": {
      "command": "npx",
      "args": ["-y", "ibluetext-mcp"],
      "env": { "IBT_API_KEY": "sk-ibt-your_key_here" }
    }
  }
}

Claude Code: claude mcp add ibluetext --env IBT_API_KEY=sk-ibt-... -- npx -y ibluetext-mcp

The package adds SMS verification, verify-widget sites and reply webhooks to the hosted tool set.

Notes

• Paid actions return HTTP 402 when the account is out of credits or has no active line. The tool result is flagged payment_required: true; a person adds credits or a line in the iBlueText dashboard.
• Opt-outs (STOP) and each line's daily new-contact limit always apply.
• WhatsApp numbers warm up from 10 new conversations on day 1 to 300/day by day 21; someone who never replied gets at most 3 messages; under 15% replies over 7 days halves the daily limit. Open with a question like "Hey, is this {first_name}?".
• Local dev: IBT_API_KEY=sk-ibt-... node index.js (MCP over stdio). IBT_BASE overrides the API base URL.
• REST API: https://ibluetext.com/docs/ · OpenAPI: https://ibluetext.com/openapi.json · For AI agents: https://ibluetext.com/llms.txt
