About

Langroid lets you set up agents with an LLM, an optional vector store and tools, assign each agent a task, and have agents solve problems by exchanging messages. The project describes this multi-agent model as inspired by the actor model, and it states that it does not use LangChain. The README lists MCP support through an adapter that converts MCP server tools into Langroid tool messages. A Claude Code plugin is also available.
