Best MCP servers for team chat

Team chat is where work actually happens: decisions get made in a thread, context lives in a channel, and the answer to half your questions is buried in a message someone sent last Tuesday. An agent connected to your chat platform can read those conversations, post updates, and respond in context, turning the place your team already talks into a surface the agent can both listen to and act on. The right server depends on where your team lives, a workplace messaging suite, a community-oriented platform, a lightweight bot-friendly app, or a self-hostable open alternative. The recurring need is the same: let the agent read and send messages where the team works. The servers below cover the common shapes, each a real MCP server with a verified, current install config.
