IntelliNode

IntelliNode is an open-source library for building AI agents, RAG chatbots and MCP servers in Python or Node.js. It gives developers one input layer for OpenAI, Claude, Gemini and local models served through vLLM, so switching providers needs few code changes.

Multi-model workflows are described as a graph of tasks, letting one model's output feed the next step. A built-in evaluation module runs the same prompts across several models and scores them with metrics, which helps when picking a provider for a job.

It installs with pip install intelli for Python or npm i intellinode for Node.js, and the source is on GitHub. The site publishes step-by-step guides, such as building an MCP server for your own API or a phone-answering voice agent in Python, and the framework was used in an IEEE paper on multi-agent ICU prediction.
