Mattermost MCP server to enable Claude to interact with Mattermost Workspaces
Connect Mattermost to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Mattermost MCP server to enable Claude to interact with Mattermost Workspaces. The mattermost mcp server is what makes that connection.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
mattermost_list_channels — List public channels in the workspacemattermost_get_channel_history — Get recent messages from a channelmattermost_post_message — Post a new message to a channelmattermost_reply_to_thread — Reply to a specific message threadmattermost_add_reaction — Add an emoji reaction to a messagemattermost_get_thread_replies — Get all replies in a threadmattermost_run_monitoring — Trigger the topic monitoring process immediatelymattermost_get_users — Get a list of users in the workspacemattermost_get_user_profile — Get detailed profile information for a userSetup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
This sits in the monitoring and observability group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Mattermost's toolset — mattermost_list_channels, mattermost_get_channel_history, mattermost_post_message and 6 more — is a fair guide to whether it matches your workflow. It is maintained by pvev; worth a glance at recent repository activity before you build anything load-bearing on it.
