"A server for finding information about message bus systems and architectures" matching MCP servers:

Enables coding agents to coordinate in spaces through direct messages, topics, blackboards, and durable inboxes, exposing bus tools over MCP and RPC while pushing inbox updates over SSE.

An MCP server that lets AI agents register a name and bio, discover one another, exchange messages, and be woken when mail arrives rather than polling, backed by a shared SQLite database over stdio for one machine or HTTP for a team.

Exposes a shared-directory message bus to coding agents as MCP tools: receive pending messages, send one-way announcements, ask a peer and block until answered, and track peer status. Lets agents read and update per-agent state and group announcement boards so several agents working on the same machine stay coordinated without a broker, port, or account.

Enables AI agents to delegate scoped tasks across multiple providers like Codex, Claude Code, and Antigravity through a single local MCP server, with quota monitoring, notifications, and remote control via messaging apps.

Real-time push notifications and alert sounds free you from staring at the screen. While the AI works, you can comfortably enjoy a cup of coffee.

Enables AI coding agents running in separate apps to exchange messages, tasks, presence, and context through shared rooms, direct threads, and webhook wake-ups. A human owner stays in control by approving proposed plans before execution and reviewing posted results, with safety limits on agent-to-agent chatter.

Enables authenticated, explicit-text message exchange between independent clients through a durable queue with idempotent sends, replay-safe inbox reads, bounded conversations, pause/reset controls, and client-driven polling.

Enables Codex and Claude Code sessions to discover one another and exchange direct, group, and threaded messages with read receipts, backed by a local SQLite store and native notifications that wake the receiving client. Supports optional end-to-end encrypted relay messaging between trusted machines while local delivery continues to work offline.

Enables AI clients to read and search macOS Messages history through a read-only MCP interface.

An MCP broker that provides local communication between Manager and Lead agents for message routing and coordination.

Enables sending, reading, archiving, and threading messages across parallel Claude Code sessions with per-session addressing and status monitoring.

Enables Claude Code agents on the same project to message each other directly, with server-side guardrails, human oversight and control via Telegram, approval workflows for outside changes, and one-tap sharing of agent setup.

Enables scheduled AI workflows to route notifications to QQ and Telegram via REST, MCP, or Gmail, with retries and audit, without the relay calling paid LLM APIs.

Enables coordination and communication between multiple Claude Code sessions across machines via a chat server, providing tools for sending messages, waiting for responses, and managing session status.

Enables independently operated AI clients to exchange private 1:1 messages and files using authenticated participant identities, with retry deduplication, status tracking, notifications, and owner conversation inspection. Provides REST and MCP tools for messaging, attachments, subscriptions, and replay.

Enables two-way communication between Claude Code and clew, allowing message passing and command execution via MCP tools or native peer mesh with auto-reply support.

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

Relays a result screenshot to Slack so you can review a coding agent's output without opening the app.

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.

MCP server for sending messages to Slack channels and replying in threads, with automatic channel name resolution and support for Claude Desktop and KADI agents.

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.

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

Enables reading and sending messages in Google Messages for web through a paired Chrome tab using chromefile, with tools for status, listing conversations, reading message history, and sending texts.

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 posting messages to a Slack channel using a bot token, with support for stdio and HTTP modes.

Read-only MCP server for finding Discord messages. It enables searching guild messages, locating messages from jump URLs, and reading context around results.

Enables comprehensive Google Meet and Calendar management through Google Calendar API v3 and Google Meet API v2, supporting calendar event creation with Meet links, space management, transcription, recording, attendance tracking, and meeting moderation controls.

A standalone remote MCP server that lets AI clients read, search, post, schedule, and manage messages and files in Mattermost as each individual user through per-user OAuth, without requiring a plugin or Enterprise license. It keeps each user's Mattermost tokens server-side, enforces per-user permissions and API limits, and ships guard rails against duplicate or unintended posts.

Enables AI apps on the local computer to search and read Thunderbird mail, organize messages, manage contacts, and prepare drafts, with optional controlled sending. Access is limited to user-selected accounts and tool groups, with local-only communication and a pause control.

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