Persistent memory for AI agents — grounded in neuroscience. Transform raw information into knowledge, wisdom, and understanding.
PAMK is an MCP-native memory system that gives AI agents the ability to remember, learn, and grow wiser over time. It works with Claude, Cursor, VS Code, and any MCP-compatible client.
Persistent facts, preferences, and constraints. Event-sourced mutations with full audit trail.
Append-only event logs with deterministic chunking. Hybrid BM25 + semantic search retrieval.
Sleep-like distillation transforms raw conversations into structured knowledge through daily digests.
Six capabilities no other memory system offers.
First-class Model Context Protocol integration. Works out of the box with Claude Desktop, Claude Code, Cursor, and any MCP client.
Scientifically-grounded memory strengthening. Resurfaces knowledge before it's forgotten, using the proven SuperMemo algorithm.
Detects when beliefs change or contradict over time. Track confidence trajectories and spot evolving understanding.
Daily digests extract decisions, open loops, entities, and causal facts — just like how sleep consolidates human memory.
Four decay models (exponential, power law, Ebbinghaus, SM-2) with adaptive calibration and staleness monitoring.
Structured metadata-aware temporal constraint solving. Not just text matching — explicit date arithmetic and time window filtering.
The only production-grade MCP-native memory system.
