Messaging
MCPs for Slack, Discord, Telegram, and team chat
TL;DR
Messaging MCP servers let agents read, post, and react in team chat platforms — Slack, Discord, Teams, Telegram. They enable human-in-the-loop approvals, proactive alerts, and agent-driven conversations. Nearly every production agent workflow ends with a messaging step.
About Messaging
Messaging MCPs connect agents to Slack, Discord, Microsoft Teams, Telegram, and other chat platforms. Agents can read channels, post messages, DM users, react with emoji, and orchestrate human-in-the-loop workflows.
Common use cases
- Post alerts to Slack when a metric crosses a threshold
- DM users to request approval before the agent acts
- Summarize unread Slack threads every morning
- Cross-post Discord announcements to Telegram
- Run a bot that triages support requests and escalates to humans

Frequently asked questions
Which messaging MCP is most complete?
The official Slack MCP is currently the richest — full API coverage (messages, channels, users, reactions, files, search).
Can agents DM users?
Yes — most messaging MCPs expose a `send_dm` or `postMessage` tool. Respect rate limits and user privacy settings.
How do I avoid spamming my team?
Add approval gates in your agent logic, rate-limit noisy alerts, and route low-priority messages to a dedicated #agent-activity channel.
Do messaging MCPs handle attachments?
Yes — Slack and Discord MCPs support file uploads, image attachments, and rich embeds out of the box.
