Volcano SDK, an open-source TypeScript software development kit, streamlines the process of building AI agents by combining large language model (LLM) reasoning with real-world actions through MCP tools, reducing the need for extensive code. It enables developers to create workflows with as few as nine lines of code, automatically managing tool schemas, context flow, provider switching, and error handling. This SDK supports multi-provider setups, allowing different LLMs like GPT-5 and Claude to interact seamlessly within a single workflow, enhancing productivity with its simple, chainable, and production-ready design. Volcano SDK's approach prioritizes the automatic discovery and utilization of MCP tools, offering a type-safe, intuitive, and efficient framework for developing AI agents that can perform tasks such as data analysis and report generation, ultimately fulfilling its goal of simplifying the creation of multi-step workflows that integrate diverse LLMs and tools.
