VoltAgent

VoltAgent is an open-source TypeScript framework that acts as this essential toolkit. It simplifies the development of AI agent applications by providing modular building blocks, standardized patterns, and abstractions. Whether you're creating chatbots, virtual assistants, automated workflows, or complex multi-agent systems, VoltAgent handles the underlying complexity, allowing you to focus on defining your agents' capabilities and logic.

Key features:

• Agent Core: Define agents with descriptions, LLM providers, tools, and memory management.
• Multi-Agent Systems: Build complex workflows using Supervisor Agents coordinating multiple specialized Sub-Agents.
• Tool Usage & Lifecycle: Equip agents with custom or pre-built tools (functions) with type-safety (Zod), lifecycle hooks, and cancellation support to interact with external systems.
• Flexible LLM Support: Integrate seamlessly with various LLM providers (OpenAI, Anthropic, Google, etc.) and easily switch between models.
• Memory Management: Enable agents to retain context across interactions using different configurable memory providers.
• Observability & Debugging: Visually monitor agent states, interactions, logs, and performance via the VoltAgent Console.
• Voice Interaction: Build voice-enabled agents capable of speech recognition and synthesis using the @voltagent/voice package.
• Data Retrieval & RAG: Integrate specialized retriever agents for efficient information fetching and Retrieval-Augmented Generation (RAG) from various sources.
• Model Context Protocol (MCP) Support: Connect to external tool servers (HTTP/stdio) adhering to the MCP standard for extended capabilities.
• Prompt Engineering Tools: Leverage utilities like createPrompt for crafting and managing effective prompts for your agents.
• Framework Compatibility: Designed for easy integration into existing Node.js applications and popular frameworks.
