VoltAgent is an end-to-end AI Agent Engineering Platform that consists of two main parts:

• Open-Source TypeScript Framework – Memory, RAG, Guardrails, Tools, MCP, Voice, Workflow, and more.
• VoltOps Console Cloud Self-Hosted – Observability, Automation, Deployment, Evals, Guardrails, Prompts, and more.

Build agents with full code control and ship them with production-ready visibility and operations.

Core TypeScript Framework

With the open-source framework, you can build intelligent agents with memory, tools, and multi-step workflows while connecting to any AI provider. Create sophisticated multi-agent systems where specialized agents work together under supervisor coordination.

• Core Runtime (@voltagent/core): Define agents with typed roles, tools, memory, and model providers in one place so everything stays organized.
• Workflow Engine: Describe multi-step automations declaratively rather than stitching together custom control flow.
• Supervisors & Sub-Agents: Run teams of specialized agents under a supervisor runtime that routes tasks and keeps them in sync.
• Tool Registry & MCP: Ship Zod-typed tools with lifecycle hooks and cancellation, and connect to Model Context Protocol servers without extra glue code.
• LLM Compatibility: Swap between OpenAI, Anthropic, Google, or other providers by changing config, not rewriting agent logic.
• Memory: Attach durable memory adapters so agents remember important context across runs.
• Resumable Streaming: Let clients reconnect to in-flight streams after refresh and continue receiving the same response.
• Retrieval & RAG: Plug in retriever agents to pull facts from your data sources and ground responses (RAG) before the model answers.
• VoltAgent Knowledge Base: Use the managed RAG service for document ingestion, chunking, embeddings, and search.
• Voice: Add text-to-speech and speech-to-text capabilities with OpenAI, ElevenLabs, or custom voice providers.
• Guardrails: Intercept and validate agent input or output at runtime to enforce content policies and safety rules.
• Evals: Run agent eval suites alongside your workflows to measure and improve agent behavior.

MCP Server (@voltagent/mcp-docs-server)

You can use the MCP server @voltagent/mcp-docs-server to teach your LLM how to use VoltAgent for AI-powered coding assistants like Claude, Cursor, or Windsurf. This allows AI assistants to access VoltAgent documentation, examples, and changelogs
