Hi Product Hunt, Spring AI Playground is a self-hosted web UI for Java/Spring developers to experiment with MCP tools, vector databases, and LLMs in a single environment. It makes prototyping PoCs, testing AI workflows, and exploring RAG/MCP concepts fast and straightforward. Key features include: - MCP Tool Playground: Run interactive calls and explore available tools. - Vector DB + RAG: Ingest, embed, and retrieve documents across multiple stores. - Chat Integration: Switch models and providers (local or cloud) to validate workflows. Docker-ready and demo-friendly. Your feedback is valuable—what features or integrations should we prioritize? Star the repo and share your thoughts. https://github.com/JM-Lab/spring...
