Can I use Mermaid as a CLI?

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

Can I expose Mermaid through MCP?

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

Where are Mermaid credentials stored?

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

Can I deny write access for Mermaid MCP tools?

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

Mermaid for agents

No credentials required; available in web and CLI hosts when runtime dependencies are installed.

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