## Description

Engram MCP provides AI agents with reliable memory capabilities through explainable retrieval mechanisms, built by Lumetra as a streamable HTTP service. The server connects to Lumetra's hosted Engram service at engram.lumetra.io using API key authentication, enabling agents to store and retrieve information with transparent reasoning about why specific memories were surfaced. This implementation is valuable for AI systems that need persistent memory across conversations, knowledge management workflows, or applications requiring auditable retrieval decisions where understanding the basis for recalled information is critical.
