"Optimizing AI Model Thinking, Token Usage, and Context Size" matching MCP servers:

Summarizes Slack activity and GitLab merge requests with OpenAI to help generate daily standups, weekly reports, or quarterly check-ins.

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

Allows coding agents to securely retrieve curated, sealed Slack message bundles (capsules) via MCP, with full audit and expiration controls.

Enables multiple AI agents and humans working in the same project to share status, exchange messages, and claim files through a local collaboration board. It supports project-specific enablement, conflict-aware file claims, and shared state via SQLite.

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 group chat for AI agents. Every agent on your private network connects through an MCP tool to one central server and exchanges first-person messages with the other registered agents — a WhatsApp for agents.

Enables authorized MCP clients to perform five read-only operations — checking connection status, listing conversations, reading messages, searching, and polling for changes — over selected Discord server channels and DMs, with scope-based authentication, retention limits, and no ability to send messages or moderate.

Enables AI agent teammates to exchange typed decisions, contracts, pitfalls, and questions in real time over an end-to-end-encrypted blind relay, keeping every agent's context synchronized. Agents autonomously publish and consume peer updates through password-paired channels with no accounts or platform required.

Implements a secure message communication protocol for handling exchanges between the banking chatbot and Azure OpenAI, providing message queuing, reliability, and detailed logging.

Enables LLM agents to operate WhatsApp through the Evolution API, providing tools to list groups, fetch message history, and send text messages to groups or individual phone numbers.

A read-only MCP server that connects ChatGPT/Codex to LINE Desktop's local encrypted database to provide private conversation advice without sending messages.

Read chats, search messages and check members on your own Telegram account over MTProto. Any change is a typed plan a person applies from the terminal; no tool sends by itself.

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.

An MCP server that lets you schedule AI phone calls and manage Leximo assignments directly from Claude Desktop or Claude Code.

Enables AI assistants to query the Voxie AI Phone Number Directory, list AI services, and obtain webchat URLs to interact with Voxie AI personas.

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.

A free MCP server for growing Discord communities, offering tools to search public servers, analyze engagement, and draft messages, with optional premium AI features powered by DeepSeek.

Exposes 105 MCP tools that let Claude and ChatGPT read and analyse a Mizito workspace's chats, projects, tasks, calendar, letters, minutes, surveys, notes and files (including PDF, Word, Excel and image content). Write, CRM and admin tools can optionally be enabled so the assistant can also send messages and letters, create and repeat tasks, manage kanban boards, and handle customer records.

Bidirectional chat bridge between Factorio and Claude Code via MCP protocol, enabling players to send /companion commands and receive AI responses.

Enables multiple AI agents to share persistent memory, interact through a game hall and AI lounge, and bridge messages to ChatGPT and Claude browser sessions via MCP tools.

Enables real-time communication and shared vector memory between Claude Code, OpenAI Codex CLI, and Google Gemini CLI. It allows different AI platforms to exchange messages, share context, and collaborate through a unified MCP interface.

An MCP server that provides AI applications with a toolset for an Artificial Virtual Assistant (AVA) integrated with the Gmail API. It enables users to automate email management and personal tasks through secure Google OAuth authentication.

Exposes 219+ tools for Slack, Gmail, Google Workspace, Jira, Confluence, CRM, and phone, enabling a multi-agent AI coworker with memory and proactive suggestions.
