"Deploying an MCP service in an offline environment" matching MCP servers:

A persistent 24/7 background daemon that aggregates all downstream MCP servers into one unified connection and layers on a real-time notification gateway so AI agents can receive events from X/Twitter, Slack, Email, and webhooks.

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.

This MCP server enables an AI receptionist to manage field-service bookings end-to-end: checking technician availability from live Outlook calendars, sending asynchronous SMS offers, tracking request status, and creating confirmed Outlook events with ETag-locked concurrency, all without customer sign-in.

An MCP (Multi-Agent Conversation Protocol) Server that enables interaction with Adyen's Checkout Utility Service API through natural language, auto-generated using AG2's MCP builder.

Provides over 1,000 creative ways to decline requests across four categories (polite, humorous, professional, and creative). The MCP server wraps a REST API to help users craft professional rejections through natural language interactions.

Enables an AI assistant to place user-approved phone calls in the callee's language through your own Bland or Twilio account, with language detection, script generation, cost estimates, and safety guard rails. Includes a preview-then-confirm gate, plus call status, transcripts, and summaries.

Enables multi-account email management with AI-powered monitoring, intelligent filtering, and automated notifications across multiple platforms including Gmail, Outlook, QQ Mail, and 163 Mail.

A Model Context Protocol service for comprehensive email management that supports multiple email providers, with complete functionality for viewing, organizing, and batch processing emails.

Enables sending messages and scheduling reminders through multiple platforms including Telegram and Feishu. Supports real-time messaging and cron-based scheduled notifications with comprehensive logging and error handling.

An interface enabling high-frequency communication between AI tools (like Cursor and Windsurf) and users, allowing for option selection and information gathering through CLI, Web, or PyQt interfaces.

Integrates with Service Desk Plus Cloud API to enable AI assistants to manage IT service requests, technicians, and communications via natural language.

Enables sending emails (including mass emailing), querying, updating, and canceling delayed emails via the Resend API.

Generate professional AI-powered presentations from a topic, raw text, or document file. Export to PPTX, PDF, image, or shareable link.

Enables Claude and other MCP clients to search, read, write and organise mail on Stalwart servers over JMAP — including folders, Sieve filters, out-of-office replies and one-click unsubscribe — with draft-first and confirmation safeguards against prompt injection. A separate admin endpoint additionally exposes account, domain, mailing-list, queue, IP, log and task management through Stalwart's JMAP management API.

Enables AI-driven interaction with Twilio call services, including initiating outbound calls and retrieving call history via FastMCP tools.

Enables AI clients to check an application balance and preview or send bulk SMS and airtime, either through a hosted OAuth connection that needs no local install or via a self-hosted stdio/Cloudflare Workers deployment using your own credentials. Sending is preview-only by default and gated behind environment, recipient allowlist, and mutation opt-in settings.

Enables an IMAP/SMTP mailbox to be used safely by an agent: it composes correctly encoded HTML-plus-plain-text messages and files them in the Drafts folder for human review, with outbound delivery available only when explicitly opted in.

Released 3.0.0: 22 MCP tools, guided offline setup, local stdio, Chrome and manual login. No hosted deployment or job-research brief. Writes need opt-in, reviewed preview and human approval. Unofficial; provider compatibility, first-use cohorts, coordinated erasure and Windows privacy proof remain unverified. No mandatory paid service.

An MCP server that lets an AI agent work with an ActiveMQ Artemis broker.

An MCP server for managing RingCentral's Feature Flag Service (FFS) that enables searching for flags and retrieving user account information. It allows users to check and update feature flag statuses for specific accounts or extensions through natural language interfaces.

A Model Context Protocol (MCP) server that empowers LLMs to schedule persistent background jobs on servers/NAS, recursively crawl web documentation into an offline SQLite RAG knowledge base, and dispatch smartphone push notifications with interactive approvals.

An MCP server that provides native Discord tools for Claude Code, enabling bidirectional communication with remote agents or humans via the Discord REST API. It allows users to send messages, read channel history, and manage reactions directly from their local environment.

Enables scheduling and triggering reminders delivered via Slack or Telegram through natural language, using an external cron service to ensure delivery even when the server is offline.

Enables MCP-compatible AI clients to read local WeChat data through an existing WxLens HTTP service, so users can find messages, extract a person's statements, summarize discussions, scan multiple groups, and read related articles or attachments.

A TypeScript-based MCP server that implements an email sending system, allowing Claude to send emails via the blastengine service.

Enables AI agents to join and actively participate in video calls, providing real-time interaction and meeting tools through an MCP server.

Pushary is an MCP server that connects AI agents to push notifications, enabling human-in-the-loop approval from a phone.

Enables an AI assistant to drive a personal Discord account as if it were the user: reading and sending messages and DMs, managing servers, channels, roles, permissions, threads, invites and friends, joining voice, and clicking buttons, menus, modals and slash commands. An optional hardened mode runs it as an always-on local service with loopback-only HTTP access, encrypted credentials, an allowlist of reviewed tools, and an AFK session that keeps push notifications flowing.

An unofficial read-only MCP server for viewing BOOTH seller management pages in MCP clients.

Enables AI agents to send and manage email, message and collaborate with other agents on shared tasks, and upload, list, download, and delete files in cloud storage. Requires an agent-identity platform API key supplied via environment variable.
