"A tool for running code in a REPL-like environment" matching MCP servers:

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

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.

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.

Lets an AI assistant read call and message history, send texts and picture messages, reach Phone Book contacts by name, and — once switched on — place calls run by a voice agent, all limited to the phone numbers the user ticks. Hosted remotely with OAuth sign-in, so nothing needs to be installed locally.

Enables AI assistants to read, search, draft, and send email with attachments over IMAP/SMTP, keeping passwords in the OS keyring and gating outgoing mail on user approval for CMMC Level 2 environments.

Run free live audience Q&A and polls from your agent: start an AskOne room, add and launch a poll, approve or hide questions and mark them answered, close the room, then read the questions as a FAQ draft and get the results. Free AI moderation. Uses an organization API token from askone.org

Wraps Claude Code as a server using the Model Context Protocol (MCP), allowing teams to interact with Claude Code through a Slack bot interface.

Lets a human review what an AI agent is about to post to a chat tool (Slack first) before it is sent. Renders the draft, destination and warnings (@here/@channel, unresolved mentions, format issues) in a neutral local HTML preview; never sends anything.

Discover and connect your agents with other agents via A2A protocol. Share resources for free or fee.

MCP server that connects Claude Code to Slack, allowing two-way communication via Slack Socket Mode without tunnels.

Lets you @mention a bot in a Slack channel or DM to send work to a local Claude Code session and watch it run, with live self-updating turn cards, threaded answers, progress checklists and a per-channel inbox with read cursors. It runs entirely on your machine over Slack Socket Mode—no tunnel or public IP—routes misdelivered messages to the right project, and masks credentials in anything it posts back.

Provides MCP-compatible AI clients with full access to a Flarum forum's API, enabling reading, searching, creating discussions, replying, moderation, and management of users, tags, and groups.

Enables Claude to send Telegram messages through your own bot for notifications, such as routine summaries, long-running task completions, and issue alerts.

Integrates Claude Code with DingTalk (钉钉) robot notifications, allowing users to send task completion alerts and various message formats to DingTalk groups from Claude Code.

MCP server integrating Telegram bot with Qwen Code for AI chat, supporting persistent sessions, group chat, and advanced features via mention-based triggers.

Enables ChatGPT and Codex to interact with Zoho Mail through Zoho's official MCP service, with safe workflows and capability boundaries.

Enables sending properly rendered Markdown messages to Telegram and remotely resetting Claude Code's context, addressing gaps in Anthropic's official Telegram channel.

Enables users to drive a Claude Code session from chat messages on a linked phone number or an official business account, with bidirectional text and media, local voice-note transcription, per-chat personalities, pairing-code access control, and tool-approval by emoji reaction. It also supports polls, scheduled tasks, and context recovery after restarts for other stdio MCP clients.

MCP server that pushes Feishu (Lark) messages to Claude Code sessions and allows Claude to reply directly in Feishu.

Enables bidirectional communication with Claude via WhatsApp, allowing commands, file sharing, and persistent context without needing Claude Code open.
