ART Framework

What it does

ART (Agentic Reactive Triad) is a production-ready runtime for building sophisticated LLM-powered agents in TypeScript. It connects to MCP-compliant servers to dynamically discover and execute tools, enabling agents to reason, plan, and act across external systems and APIs. With built-in support for multi-provider LLMs (OpenAI, Anthropic, Google Gemini, DeepSeek, Groq, Ollama), ART gives AI agents the ability to orchestrate complex multi-step workflows while maintaining durable state across sessions.

Tools

• PESAgent (Plan-Execute-Synthesize) — Decomposes user intent into a structured TodoList, executes each step with tool-aware validation (TAEF), and synthesizes results into rich responses.
• MCP Tool Discovery — Dynamically discovers and calls tools from any MCP-compliant server, eliminating hard-coded integrations.
• A2A Delegation — Delegates sub-tasks to specialized agents for coordinated multi-agent workflows.
• HITL V2 (Human-in-the-Loop) — Pauses execution for human approval with full state preservation and seamless resumption.
• Persistent State — Crashes and restarts are handled gracefully; agents resume exactly where they left off via automatic state hydration.
• OAuth & Auth Strategies — Built-in PKCE, generic OAuth, and API key management for secure external service access.

Installation

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "art-framework": {
      "command": "npx",
      "args": ["art-framework"]
    }
  }
}

Supported hosts

Claude Desktop (stdio). ART is primarily a developer framework consumed as an npm library; MCP server integration enables tool discovery from any MCP-compatible host.
