Comms & social MCP servers
Where your team already talks: Slack, email, and messaging platforms. These servers let an assistant search history, summarize threads, and draft replies. The permissions panel tells you whether it can only read or also speak as you.
What engineers use them for
- Search messages and summarize long channels
- Draft replies with the relevant thread as context
- Post updates when a job finishes or breaks
- Turn a decision buried in chat into a document
