Communication MCP servers connect AI models to messaging and collaboration tools, Slack, email, calendars, and team platforms, through the Model Context Protocol. They let an assistant read, send, and act on communication rather than staying separate from where your conversations actually happen.

What communication MCP servers enable

Connected to your messaging tools, a model can summarize a Slack channel, draft and send a message, check a calendar, or pull context from a thread, bringing AI into the flow of team communication instead of a separate window.

Permissions for communication MCP servers

Since these servers can read and send messages on your behalf, scope them tightly and be cautious with send permissions. The MCP servers category explains the protocol, and the communication tools are the platforms these servers connect to.

Frequently Asked Questions

What communication platforms have MCP servers?▾
MCP servers exist for Slack (reading channels, sending messages), Gmail (reading emails, drafting and sending), Outlook, Discord, Linear, and Jira. The ecosystem expands regularly. For platforms without official servers, developers build custom servers using the MCP SDK.
Can an AI assistant send messages on my behalf through MCP?▾
Yes - communication MCP servers can send messages, emails, and notifications with your credentials. This should be used carefully: configure the server to require approval before sending, restrict to specific channels or recipients, and review every action the AI proposes in communication contexts where mistakes have real social consequences.
How do I prevent an AI from sending unwanted messages?▾
Most well-designed MCP servers include confirmation steps before taking irreversible actions like sending messages. Configure your MCP setup to require explicit user approval for send operations. Restrict the server's scope to read-only access initially, only enabling write access when you have tested and trust the workflow.
What do communication MCP servers connect to?▾
They connect AI models to messaging and collaboration tools such as Slack, email, calendars, and team platforms, through the Model Context Protocol, so an assistant can read, summarize, and act on communication. Connected this way, a model can summarize a channel, draft and send a message, or check a calendar as part of a task, bringing AI into the flow of team communication rather than a separate window. Availability varies by platform, and the ecosystem grows as more tools implement MCP servers.
Can an AI send messages through a communication MCP server?▾
Yes, if you grant send permissions, a connected model can send messages, emails, or calendar invites on your behalf, which is powerful and warrants caution, since a message sent in your name is visible and hard to undo. The safer approach limits autonomy for sending, having the model draft while you approve anything important, and scopes access tightly. Read permissions for summarizing and pulling context are lower-risk than send permissions, so grant sending capability deliberately rather than by default.
Are communication MCP servers secure?▾
They are as secure as the permissions and providers you choose, and because they touch sensitive conversations, care matters. A communication server can let a model read and send your messages, so install only servers you trust, scope access to what a task needs, be especially careful with send permissions, and review what the connected model can do. Treat it like any integration with access to your email and chat, since that is effectively what it is, and match the trust you extend to the sensitivity of your communication.
