MCP server for qualifying and responding to inbound leads in seconds using a multi-agent AI pipeline.

Publish reliable, duplicate-free Telegram posts from ChatGPT — manually or as part of a scheduled workflow.

Enables AI coding agents to autonomously interact with, test, click inline buttons on, and verify Telegram bots end-to-end via MTProto.

MCP server for Yahoo Mail over IMAP+SMTP that enables AI assistants to manage emails fully—listing, reading, searching, threading, flagging, moving, archiving, handling attachments, and sending/reply/forward/draft—using an app-specific password.

Enables AI agents to interact with Discourse forums through search, reading topics/posts, managing categories and tags, chat channels, and optionally creating content with safeguarded write operations.

An MCP server that gives any agent an end-to-end-encrypted, sovereign inbox on xete, enabling identity lookup, encrypted messaging, and inbox management.

Enables two Claude agents to communicate directly through an end-to-end encrypted tunnel, eliminating the need for manual copy-pasting and facilitating real-time collaboration.

Email for AI agents. Create inboxes, send and receive emails without phone or CAPTCHA. Inboxes are server-readable, not end-to-end encrypted.

Enables agents to inspect captured emails, messages, and webhooks across multiple channels, read OTP codes, and simulate inbound events for end-to-end testing.

Official MCP server for Shipmail, enabling agents to manage domains, mailboxes, messages, threads, webhooks, and suppressions via natural language.

An agentic AI system that automates end-to-end HR workflows, from onboarding to scheduling, using the Model Context Protocol (MCP).

Gives on-the-fly inboxes to AI agents. Agents / LLM's can send, receive, and take action in isolated inboxes. Built for AI unlike Gmail. Check us out at agentmail.to

Enables AI assistants to control Discord servers with 93 tools for server management, moderation, voice TTS, AI chat via OpenRouter, and World of Warships stats lookup through the Model Context Protocol.

Enables AI agents to autonomously interact with, test, click buttons on, and verify Telegram bots end-to-end via the MTProto protocol.

MCP server for end-to-end encrypted multi-agent chat rooms, enabling turn-based hosts like Codex and Claude Code to claim, process, and acknowledge tasks.

MCP server for VoidSend enabling AI agents to send and receive end-to-end encrypted messages.

Discover and communicate with AI agents over encrypted P2P networks. Zero-config NAT traversal, skill-based routing, and end-to-end encryption.

Enables AI clients to build and manage Genesys Cloud resources such as queues, skills, users, wrap-up codes, Architect flows, outbound campaigns and cadences, and agentic virtual agents end to end. It provides tools for creating, validating, diagramming, testing, and publishing these resources through Genesys Cloud APIs.

Enables AI agents to exchange end-to-end encrypted messages, negotiate availability and plans, and share notes in project spaces through a local node exposing 13 MCP tools and an encrypted relay that only stores ciphertext.

Enables AI assistants to read, search, and reply to personal LINE messages, including end-to-end-encrypted chats and media, all decrypted locally.

An enterprise-grade MCP server that provides production-ready IMAP email integration with advanced reliability features, comprehensive monitoring, and secure account management.

Enables Claude agents to report their working, waiting, done and error status, ask questions you answer in the office, hand work off to colleagues, and get an overview or end-of-day summary of who is doing what per project.

Enables AI coding sessions across different coding tools to collaborate through end-to-end encrypted messaging, work handover, and change review, while the relay stores only ciphertext.

An end-to-end encrypted inbox where AI agents deliver reports, files, and artifacts, and submit outbound email or spend requests for human approval. Content is decrypted in the browser, never on the server.
