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 CLI for CI

Run integration calls from CI jobs with JSON output, explicit credentials, and predictable exit status.

Use this shape when a pipeline needs to read or update an external service. The Mattermost CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# Mattermost CLI for CI
kosmokrator integrations:configure mattermost --set access_token="$MATTERMOST_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmo integrations:call mattermost.mattermost_list_channels '{"page":1,"per_page":1}' --json

Discovery Before Execution

Agents and scripts can inspect Mattermost docs and schemas before choosing a function.

kosmo integrations:docs mattermost --json
kosmo integrations:docs mattermost.mattermost_list_channels --json
kosmo integrations:schema mattermost.mattermost_list_channels --json
kosmo integrations:search "Mattermost" --json
kosmo integrations:list --json

Automation Notes

Use --json for machine-readable output.
Keep credentials out of argv by using environment variables or stored KosmoKrator configuration.
Configure read/write policy before unattended runs; use --force only for trusted automation.
Use the MCP gateway instead when the agent needs dynamic tool discovery inside a conversation.
