Communication MCP Servers

Your IMAP mailbox as an MCP server: list accounts and folders, search and read mail, attachments, drafts. Write tools only where the mailbox owner allows them, and email is sent only after the owner approves it. OAuth 2.1, hosted at mcp4mail.online, open source (MIT) and self-hostable.

Disposable, receive-only email inboxes for AI agents. Create an address, wait for the verification email, and get the extracted code or magic link back. OAuth, hosted in the EU.

WhatsApp for Claude, ChatGPT or any AI agent. Search chats, see who is waiting for a reply, and send messages from personal WhatsApp or the official Business API.

Official hosted Wati MCP server. Manage WhatsApp and Instagram contacts, chats, campaigns and templates, plus Astra AI agents, from Claude, ChatGPT, Cursor and other AI clients. OAuth sign-in, no API key. Endpoints: https://mcp.wati.io/mcp (global), https://eu-mcp.wati.io/mcp (EU), https://ksa-mcp.wati.io/mcp (KSA).

Your saved email signature for emails AI assistants send: get it as HTML and text with your real contact details, make a free signature, and manage a company's people.

Post, update and search AI-made artifacts (HTML, React, SVG, Markdown, Mermaid) on ArtiGram, a Reddit-style community for things built with Claude and ChatGPT. Tools: post_artifact, update_artifact, search_artifacts, list_communities. Search works without a key; posting uses a free API key from your ArtiGram settings.
