"Allowing an AI agent to ask user questions during a task" matching MCP servers:

Connects AI agents to anonymous strangers for asking and answering questions in character.

Enables Claude to send questions via Telegram and receive answers from your phone, bypassing terminal popups.

Lets separate coding-agent sessions coordinate through a shared, role-addressed mailbox instead of a human relaying every message, over a single local SQLite file or a hosted server with many isolated channels. Messages can be sent as tracked obligations that stay open until one side resolves and the other confirms, alongside threads, full-text search, work statuses, and an append-only versioned pin system where protected changes require recorded agreement from every declared role.

Enables AI agents to access and interact with a Discord user account via the Discord client API, allowing them to read servers, channels, DMs, mentions, and message history, and optionally send messages and perform other actions.

An MCP server that connects to Telegram as your real user account and exposes read-only tools to read and search messages, list chats and folders, inspect group info, and download media.

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

Enables AI agents to interact with Slack using a user token, providing full access to message search, channel history, DMs, and posting as the user.

Enables interaction with Slack workspaces as a user, supporting channel listing, message posting, threading, reactions, and user management via the Slack API.

All-in-one Feishu/Lark MCP for Claude Code & Codex. 84 tools, 3 auth layers, send-as-user (cookie + protobuf protocol path). Covers IM, docs, bitable, wiki, drive, calendar, tasks v2, OKR, realtime WS events.

Integrates Telegram user account with MCP, exposing operations like reading and sending messages, managing chats, and more via stdio or SSE transport.

Enables AI assistants to directly control a personal Telegram account via MTProto, providing access to chats, messages, search, and account management features.

Enables interaction with Discord using personal user tokens instead of bot applications, allowing for seamless message management and server exploration. It provides tools for reading history, sending messages, and searching across channels and DMs directly through MCP-compatible clients.

An MCP server that helps users with ADHD traits manage Slack mentions by analyzing requests, structuring replies, and breaking tasks into small, actionable steps.

Enables AI agents to access user and message data through MCP resources, providing REST API integration for user management with paginated lists and thread tracking.

Enables interaction with Reddit through a Reddable account, allowing users to fetch posts and comments, reply to discussions, and manage comment visibility using secure API key authentication.

Enables agents to convert Markdown into WhatsApp-compatible formatting, including styled text, lists, and tables that fit a phone's monospace width.

An MCP server that enables AI agents to pause and request human approval or information via Slack, Telegram, or macOS dialogs before proceeding with actions.

A multi-modal user intent collection MCP server that allows AI agents to ask users questions and receive text/image replies.

MCP server for AI agents to send notifications, copy to clipboard, request confirmations, and collect text input from users across their devices.

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.

MCP server that enables Claude Code to communicate with other Claude Code agents over HTTP, allowing users to ask questions about remote codebases or delegate coding tasks.

A self-hosted push inbox for AI agents that enables agents to send updates and ask questions, waiting for user answers before continuing.

Enables AI assistants to request information and clarification from humans via Slack, supporting multiple roles and transport modes.

A local MCP server that lets AI agents send desktop notifications during tasks, ask for attention, and report completion. Supports macOS, Linux, and Windows, with optional webhook delivery.

Enables Claude Code to interact with Slack via MCP tools, allowing thinking steps, text streaming, status updates, and stream closure in Slack threads.

Enables Claude Code, Codex CLI and Antigravity (Gemini) agents to exchange messages that are pushed live into each other's open sessions, with mail_send, mail_check and mail_peers tools so no agent has to poll. Mail can also be bridged over SSH between machines with no shared filesystem.

Minimal MCP server for sending messages to Poke via the inbound webhook.

A multi-user AI group chat server via MCP that lets multiple users' AI agents join a shared discussion room to debate topics and reach convergence.

Enables coding agents to send files and notes into approved Zas channels and read items back, with content encrypted before leaving the machine and scoped, revocable agent access.

A public, long-lived contact and cooperation point for autonomous AI agents. Agents describe missing capabilities or resources, request help from a human operator, and leave persistent messages on a tamper-evident message board.
