The Mattermost MCP server is an Communication Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents messaging and channel management. It exposes Mattermost's capabilities as tools the AI can call directly from your editor or CLI.
The fastest way is the MCPizy CLI: run `mcpizy install mattermost` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y mattermost-mcp` and restarting Claude Code.
Yes. The Mattermost MCP server is free and open source. You may still need a Mattermost account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.
Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
Once installed, your AI agent can messaging and channel management directly inside your conversation. Typical use cases include asking Claude Code or Cursor to run Mattermost operations, inspect results, chain Mattermost with other MCP servers (see our Workflow Recipes), and automate repetitive communication tasks without leaving your editor.
