iBlueText

iBlueText MCP server

Text your customers from your AI assistant. iBlueText sends real blue-bubble iMessage, SMS and WhatsApp from a dedicated iBlueText line, 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 check which numbers are iPhones.

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, 28 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). Tests: npm test (starts the server over stdio, no key or network needed).
• Security: your API key is only ever sent to https://ibluetext.com/api/v1 (the address is fixed in the code, not configurable). Every tool is annotated: reads are readOnlyHint, and tools that message a real person (send, campaign, WhatsApp, verify) are destructiveHint + openWorldHint, so clients can ask before they run.
• REST API: https://ibluetext.com/docs/ · OpenAPI: https://ibluetext.com/openapi.json · For AI agents: https://ibluetext.com/llms.txt
