How to Set Up and Use Voltagent
VoltAgent is an open-source TypeScript AI agent framework with an MCP server that exposes VoltAgent's documentation, examples, and changelogs directly to AI coding assistants like Claude, Cursor, and Windsurf. By connecting to this server, your AI assistant gains real-time access to framework guides and implementation patterns, enabling it to write accurate VoltAgent agent code without hallucinating API details or outdated patterns.
Prerequisites
- Node.js 18+ and npm/pnpm installed
- A VoltAgent project (create one with 'npm create voltagent-app@latest') or a project where you want to use the framework
- An MCP-compatible client such as Claude Desktop, Cursor, or Windsurf
- An LLM API key (OpenAI, Anthropic, or another supported provider) for the agents you build
Create a new VoltAgent project (optional)
If you do not already have a VoltAgent project, scaffold one using the CLI. This sets up a starter agent with memory, tools, and server configuration.
npm create voltagent-app@latestAdd the VoltAgent MCP server to your client config
Add the @voltagent/mcp-server package to your MCP client configuration. This server provides documentation and context to your AI assistant about the VoltAgent framework.
{
"mcpServers": {
"voltagent": {
"command": "npx",
"args": ["-y", "@voltagent/mcp-server"]
}
}
}Restart your MCP client
Restart Claude Desktop or your chosen client to load the VoltAgent MCP server. The documentation tools will now be available during your coding sessions.
Build a VoltAgent agent with AI assistance
Ask your AI assistant to help you create a VoltAgent agent. The MCP server provides the assistant with accurate API references, type definitions, and working examples.
// Example agent scaffold
import { Agent, VoltAgent } from '@voltagent/core';
import { openai } from '@voltagent/vercel-ai';
const agent = new Agent({
name: 'my-assistant',
instructions: 'A helpful coding assistant.',
model: openai('gpt-4o-mini'),
});
new VoltAgent({ agents: { agent } });Run your agent
Start the VoltAgent development server to interact with your agents through the built-in web UI or API.

}Prompts to try
Example prompts to use with the VoltAgent MCP server connected to your coding assistant.
- "Show me how to create a VoltAgent agent with memory and custom tools."
- "What VoltAgent memory adapters are available and how do I configure LibSQL memory?"
- "Help me build a multi-agent workflow in VoltAgent where one agent delegates to another."
- "What's the correct way to define a tool with Zod validation in VoltAgent?"
- "Show me the latest VoltAgent changelog — what changed in the last release?"Troubleshooting Voltagent
The MCP server connects but the AI assistant doesn't use VoltAgent docs
Explicitly mention VoltAgent in your prompt (e.g., 'using the VoltAgent framework') to trigger the assistant to pull documentation from the MCP server rather than relying on its training data.
npx -y @voltagent/mcp-server fails with package not found
Check that the package name is correct and the npm registry is accessible. Run 'npm view @voltagent/mcp-server' to verify the package exists. If the package is still pre-release, you may need to install it from the GitHub repository directly.
Agent code generated by the AI uses incorrect API signatures
The MCP server may not have loaded fully. Restart the client, then ask a specific question like 'What does the Agent constructor accept?' to confirm the server is providing documentation context before generating agent code.
