What is Langroid?
Langroid is a Python LLM app framework that treats agents as first-class elements and makes multi-agent programming its core design principle. You attach an LLM, a vector store, and tools to an agent and assign it a Task, and agents collaborate by exchanging messages to solve problems. Inspired by the actor framework, it coordinates multi-agent interaction through hierarchical, recursive task delegation. It works with virtually any LLM without using LangChain or other LLM frameworks, and can also use MCP server tools.
- Agent (first-class element) that holds LLM conversation state, vector store, and tools

- Supports virtually any LLM, local/open or remote/commercial
- Redis-based prompt and response caching
- Qdrant, Chroma, LanceDB, and Milvus vector stores
- MCP tool adapter
- Provides a Claude Code plugin
