[](https://github.com/Kong/volcano-agent-sdk/actions/workflows/ci.yml) [](LICENSE) [](https://www.npmjs.com/package/@volcano.dev/agent) # 🌋 Volcano Agent SDK **The TypeScript SDK for Multi-Provider AI Agents** Build agents that chain LLM reasoning with MCP tools. Mix OpenAI, Claude, Mistral in one workflow. Parallel execution, branching, loops. Native retries, streaming, and typed errors. 📚 **[Read the full documentation at volcano.dev →](https://volcano.dev/)** ## ✨ Features <table> <tr> <td width="33%"> ### 🤖 Automatic Tool Selection LLM automatically picks which MCP tools to call based on your prompt. No manual routing needed. </td> <td width="33%"> ### 🧩 Multi-Agent Crews Define specialized agents and let the coordinator autonomously delegate tasks. Like automatic tool selection, but for agents. </td> <td width="33%"> ### 💬 Conversational Results Ask questions about what your agent did. Use `.summary()` or `.ask()` instead of parsing JSON. </td> </tr> <tr> <td width="33%"> ### 🔧 100s of Models OpenAI, Anthropic, Mistral, Bedrock, Vertex, Azure. Switch providers per-step or globally. </td> <td width="33%"> ### 🔄 Advanced Patterns Parallel execution, branching, loops, sub-agent composition. Enterprise-grade workflow control. </td> <td width="33%"> ### 📡 Streaming Stream tokens in real-time as LLMs generate them. Perfect for chat UIs and SSE endpoints. </td> </tr> <tr> <td width="33%"> ### 🛡️ TypeScript-First Full type safety with IntelliSense. Catch errors before runtime. </td> <td width="33%"> ### 📊 Observability OpenTelemetry traces and metrics. Export to Jaeger, Prometheus, DataDog, or any OTLP backend. </td> <td width="33%"> ### ⚡ Production-Ready Built-in retries, timeouts, error handling, and connection pooling. Battle-tested at scale. </td> </tr> </table> **[Explore all features →](https://volcano.dev/docs#key-features)** ## Quick Start ### Installation ```bash npm install @volcano.dev/agent ``` That's it! Includes MCP support and all common LLM providers (OpenAI, Anthropic, Mistral, Llama, Vertex). **[View installation guide →](https://volcano.dev/docs#installation)** ### Hello World with Automatic Tool Selection ```ts import { agent, llmOpenAI, mcp } from "@volcano.dev/agent"; const llm = llmOpenAI({ apiKey: process.env.OPENAI_API_KEY!, model: "gpt-4o-mini" }); const weather = mcp("http://localhost:8001/mcp"); const tasks = mcp("http://localhost:8002/mcp"); // Agent automatically picks the right tools const results = await agent({ llm }) .then({ prompt: "What's the weather in Seattle? If it will rain, create a task to bring an umbrella", mcps: [weather, tasks] // LLM chooses which tools to call }) .run(); // Ask questions about what happened const summary = await results.summary(llm); console.log(summary); ``` ### Multi-Agent Coordinator ```ts import { agent, llmOpenAI } from "@volcano.dev/agent"; const llm = llmOpenAI({ apiKey: process.env.OPENAI_API_KEY! }); // Define specialized agents const researcher = agent({ llm, name: 'researcher', description: 'Finds facts and data' }) .then({ prompt: "Research the topic." }) .then({ prompt: "Summarize the research." }); const writer = agent({ llm, name: 'writer', description: 'Creates content' }) .then({ prompt: "Write content." }); // Coordinator autonomously delegates to specialists const results = await agent({ llm }) .then({ prompt: "Write a blog post about quantum computing", agents: [researcher, writer] // Coordinator decides when done }) .run(); // Ask what happened const post = await results.ask(llm, "Show me the final blog post"); console.log(post); ``` **[View more examples →](https://volcano.dev/docs/examples)** ## Documentation ### 📖 Comprehensive Guides - **[Getting Started](https://volcano.dev/docs)** - Installation, quick start, core concepts - **[LLM Providers](https://volcano.dev/docs/providers)** - OpenAI, Anthropic, Mistral, Llama, Bedrock, Vertex, Azure - **[MCP Tools](https://volcano.dev/docs/mcp-tools)** - Automatic selection, OAuth authentication, connection pooling - **[Advanced Patterns](https://volcano.dev/docs/patterns)** - Parallel, branching, loops, multi-LLM workflows - **[Features](https://volcano.dev/docs/features)** - Streaming, retries, timeouts, hooks, error handling - **[Observability](https://volcano.dev/docs/observability)** - OpenTelemetry traces and metrics - **[API Reference](https://volcano.dev/docs/api)** - Complete API documentation - **[Examples](https://volcano.dev/docs/examples)** - Ready-to-run code examples ## Contributing We welcome contributions!
