A2A-compliant agent template built on LangChain's create_agent() with tool-calling. Define your tools, get a working A2A endpoint with agent discovery, task lifecycle, and JSON-RPC out of the box. Includes optional Qdrant vector store for RAG. Designed to interop with its companion langgraph-a2a template.
A production-ready template for building A2A-compliant agents using LangChain's with tool-calling. Fork it, replace the tools, and you have a working A2A agent. This template wires together a LangChain tool-calling agent and an A2A-protocol server so you can expose any set of tools as a standards-compliant agent endpoint. The included is a placeholder — replace it with your real tools and the…
Verification confirms publisher identity (repo ownership), not code safety. The security scan covers known CVEs and suspicious install scripts — it cannot prove the absence of malicious code.

The included is a placeholder — replace it with your real tools and the rest of the stack (agent construction, A2A bridging, FastAPI server) stays unchanged. An optional…
