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 CLI for Cron Jobs

Schedule repeatable integration workflows from cron while keeping credentials in KosmoKrator config.

Use the headless CLI from cron when an operation should run without an interactive agent session. The Mermaid CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# Mermaid CLI for Cron Jobs
kosmokrator integrations:configure mermaid --enable --read allow --write ask --json
kosmo integrations:call mermaid.render_mermaid '{"syntax":"example_syntax","title":"example_title","width":1,"theme":"example_theme"}' --json

Discovery Before Execution

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

kosmo integrations:docs mermaid --json
kosmo integrations:docs mermaid.render_mermaid --json
kosmo integrations:schema mermaid.render_mermaid --json
kosmo integrations:search "Mermaid" --json
kosmo integrations:list --json

Example syntax: ``` graph TD A[Start] --> B{Decision} B -->\|Yes\| C[Action] B -->\|No\| D[End] ``` Tips: - Use `graph TD` for top-down flowcharts, `graph LR` for left-to-right - Use `sequenceDiagram` for sequence diagrams - Use `erDiagram` for entity-relationship diagrams - Use `classDiagram` for class diagrams - Use `stateDiagram-v2` for state diagrams - Use `gantt` for Gantt charts - Use `pie` for pie charts - Use `gitgraph` for git graphs - Use `mindmap` for mind maps

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.
