Communication MCP Servers

Communication MCP servers connect AI assistants to Slack, Gmail, Outlook, Discord, Microsoft Teams, and other messaging platforms — making it possible to summarise threads, draft replies, search message history, and send messages without leaving your AI interface. Teams use them to reduce notification fatigue by letting Claude filter and prioritise incoming messages, or to automate routine communications like status updates and daily standup summaries. Email and Slack are the highest-demand integrations in this category.
