Mattermost MCP alternatives
The Mattermost MCP server lets an agent work with channels, messages, threads, reactions, users, teams, and files. It installs locally and runs over stdio, aimed at teams that run Mattermost as their self-hosted chat platform.
People look past it for a few reasons: their chat lives on a different platform, they need to reach phones with SMS or voice, or they want a hosted endpoint rather than a local install. The servers below cover those, from direct team-chat peers to multichannel senders.

How to choose
Rocket.Chat is the closest like-for-like, since it is another self-hostable team-chat product with a near-identical server. Matrix is the open, federated option, while Telegram and Discord swap to consumer networks. Twilio and Vonage reach phones with SMS and voice, LINE broadcasts to an audience, and Zoom fits only if your conversation lives in meetings. Choose by which platform your team actually uses and whether you need chat or phone delivery.
