About Communication MCP servers
Communication MCP servers connect AI agents to the channels your team already uses — Slack, Gmail, Microsoft Teams, Discord, and the email and chat surfaces around them. The best MCP servers for communication scope tightly: a bot token that can read a single channel and post replies, an OAuth scope that touches one mailbox, a webhook that fires only on the events you care about. With those guardrails the agent can summarise threads, draft replies, schedule reminders, and route alerts without reading more than it needs to.
Choose by primary surface. Engineering teams almost always start with the Slack MCP. Customer-facing roles begin with Gmail or Outlook MCPs to draft and triage email. Discord MCPs are the right pick for community management. For omni-channel workflows, layer a Productivity MCP (Linear, Notion, Asana) on top so action items surface in the tracker, not just the inbox.
Common mistakes: using a bot user token with global workspace scope when channel scope would do, letting an agent auto-post or auto-reply without a human-in-the-loop step (the embarrassing-message problem), and skipping rate-limit handling for high-volume channels. Each communication MCP below documents the OAuth scopes it needs and the webhook events it subscribes to. Start in a private test channel, prove the flow end-to-end, then graduate to public channels and customer-facing inboxes.

FAQ: Communication MCPs
What is the best MCP for Slack automation?
The official Slack MCP. It supports reading channels, posting messages, and searching history via a Bot Token with the right scopes.
Should I use a user token or a bot token?
Bot token, always. User tokens carry the full surface of the human who installed them — including DMs and private channels they never intended to expose to an agent. Bot tokens limit the agent to channels it was invited to.
