Can I use Mattermost as a CLI?

Yes. KosmoKrator exposes a Mattermost CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose Mattermost through MCP?

Yes. The KosmoKrator MCP gateway can expose selected Mattermost tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are Mattermost credentials stored?

Mattermost credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for Mattermost MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

Mattermost MCP, CLI, and Lua Integration for AI Agents

Mattermost integration docs for AI agents: MCP gateway setup, Mattermost CLI commands, Lua API reference, credentials, and function schemas.

Mattermost for agents

Credentials can be configured manually in web or CLI hosts.

Use this integration from Lua code mode, the headless integrations CLI, or the KosmoKrator MCP gateway. The same package metadata powers all three surfaces.
