0Latency Memory

Gives Claude persistent memory across conversations through sub-100ms semantic search and knowledge graphs. You'd reach for this when you need an AI agent to remember context between sessions without re-explaining everything or manually copy-pasting previous exchanges. Connects via SSE transport to their hosted API endpoint at mcp.0latency.ai. The recall speed means you can query stored knowledge mid-conversation without noticeable latency. Useful for building agents that accumulate domain knowledge over time, remember user preferences, or maintain state across multiple chat sessions without embedding that context into every prompt.
