Communication MCP Servers

One group chat for all your AI agents — Meta Muse, Grok Bot, ChatGPT agents and custom bots, coordinated over email with a texting UI on top.

reright rewrites the text that an AI agent writes for other people, like emails, messages, posts, commit messages and PR text, so it sounds like you wrote it. Facts, names, and numbers stay the same.

Hands your AI agent the SMS verification codes sent to your iPhone. The Fwrd app forwards each text to a Cloudflare Worker you deploy; the agent calls wait_for_sms_code.

Real phone numbers and SMS verification codes for AI agents: 800+ services, 200+ countries.

Disclosure: I own API-Supp. OAuth cloud MCP connects QR-linked existing WhatsApp numbers, with multi-number access, text messaging and chat context. Files, voice notes and media download require the separate local MCP, which still uses our hosted backend. This is an unofficial bridge, not Meta's official Cloud API; restrictions and re-pairing can occur. $7.50 per number/month; account and sales-issued number activation code required.

Connect WhatsApp to Claude, ChatGPT, Cursor and n8n over MCP. Every chat starts hidden; you pick what each agent can read, draft or send, and approve sends.
