<p align="center">MCP (Model Context Protocol) server for <a href="https://eruka.dirmacs.com">Eruka</a> — anti-hallucination context memory for AI agents.</p>

Eruka is a knowledge engine that tracks what AI agents know, what they don't know, and what they should never fabricate. It provides:

• 4 Knowledge States: CONFIRMED, INFERRED, UNCERTAIN, UNKNOWN
• Gap Detection: identifies missing information before generation
• Constraint Injection: "DO NOT FABRICATE" directives for LLM prompts
• Knowledge Decay: confidence degrades over time, facts become UNCERTAIN
• Quality Scoring: 6-layer hallucination detection pipeline
