What it does
NimbleBrain is a self-hosted platform designed for MCP Apps. Unlike standard servers, it provides an interactive UI in the sidebar with live agent-UI data sync. It enables the execution of agents on demand or via cron schedules, providing a full host for ext-apps with skill-driven prompt composition.

- Interactive UIs: Renders MCP App UI resources directly in the sidebar.
- Scheduled Automations: Run agentic loops on a recurring cron schedule.
- Multi-Agent Delegation: Built-in tool for spawning child agents for sub-tasks.

- Skill-Driven Prompting: Matches user intent to specific skill files for targeted tool access.
