crystalline vs mcp-unifi-applications

crystalline: Crystalline provides AI agents with crystallized intelligence, allowing them to accumulate and retain knowledge across sessions, unlike an LLM's fluid intelligence. It acts as a local search index on plain markdown files, enabling agents to onboard curated knowledge and capture new learnings, evolving from a stranger to a peer.; mcp-unifi-applications: This project provides a Model Context Protocol (MCP) server that transforms Ubiquiti UniFi's official API documentation into a queryable knowledge base for AI agents. It enables AI to search API endpoints, drill down into schemas, and retrieve code examples in multiple programming languages.
