konbu

The all-in-one planner, built like dev tools.

konbu is a self-hostable digital planner that combines Notion + Todoist + Google Calendar into a single Go binary. The built-in MCP server lets AI agents like Claude Desktop and Cursor read and write your data directly.

What's different

• Native MCP server — Say "schedule a dentist appointment next week" in natural language. The MCP server exposes calendar, notes, and todo operations to any MCP client.
• CLI client included — Manage everything from your terminal with konbu memo add, konbu todo list, and more.
• BYOK — Bring your own OpenAI/Anthropic API key, or use the included free tier.
• Cross-resource full-text search — Search across memos, todos, events, and bookmarks in one query.
• Self-hostable or cloud — Run on your own server with Docker, or use the hosted version at konbu-cloud.codenica.dev.

Features

• Calendar — month view, iCal import, recurring events, shared calendars
• Notes — Markdown with live preview, tags, attachments
• Todos — inline creation, due dates, tags
• Bookmarks — drag-and-drop reordering
• AI Chat — natural language interface (BYOK supported)
• Export/Import — JSON, Markdown ZIP, iCal
• Internationalization — English / Japanese

MCP Setup

After running a konbu API server (self-hosted or using the cloud version), add this to your MCP client config:

{
  "mcpServers": {
    "konbu": {
      "command": "konbu",
      "args": ["mcp"],
      "env": {
        "KONBU_API": "http://localhost:8080",
        "KONBU_API_KEY": "your-api-key"
      }
    }
  }
}

Generate an API key in Settings > Security on the web UI.
