spring-ai-playground vs Vault-for-LLM

spring-ai-playground: Spring AI Playground is a cross-platform desktop app for building, testing, validating, and executing MCP tools in a controlled local environment. It enforces a 'No Pass, No Run' workflow where tools must pass local tests before being exposed to agents. It provides a built-in MCP server, secure secret management, and supports multiple platforms.; Vault-for-LLM: Vault-for-LLM is a local-first memory layer for LLM agents. It creates a portable SQLite knowledge vault from Markdown notes, allowing agents to search and retrieve structured memory on demand. It focuses on agent-oriented memory with bounded retrieval and optional embeddings.
