Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Heku is a dynamic MCP server that lets you define tools for any API as JSON configs, serving them lazily to avoid context bloat in LLM agent manifests. Its innovative approach to tool discovery and self-managing configs via internal tools fills a practical gap for developers building complex AI agent systems.
