spring-ai-playground vs mimirs

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.; mimirs: Mímirs provides persistent project memory for AI coding agents, reducing token consumption and context overhead through local indexing, semantic search, cross-session memory, and dependency graphs. It works with multiple editors and is privacy-preserving with no cloud dependencies. The tool achieves 90-98% recall@10 on real codebases.
