Mnemoverse

Mnemoverse is a persistent memory API designed for AI agents, enabling them to store, recall, and learn from preferences, decisions, and lessons across multiple tools using a single API key. The platform addresses the challenge of fragmented or ephemeral memory in AI workflows by providing a unified memory system that works with Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, ChatGPT, Python, and REST interfaces. Unlike vector databases that rely solely on similarity-based retrieval, Mnemoverse incorporates mechanisms inspired by Hebbian associations and prediction-error feedback (Rescorla-Wagner-style), allowing it to learn which memories are most valuable based on outcome feedback and to consolidate or forget information using methods such as HDBSCAN and the Von Restorff effect.

The tool supports writing, learning from, and recalling memories with processes that filter for importance, update memory valence based on reported outcomes, and merge similar memories to maintain a dense, relevant knowledge base. Queries can be made in natural language, with the system expanding results through learned associations and boosting the ranking of memories that have led to positive outcomes. Mnemoverse exposes six core functions—memory_write, memory_read, memory_feedback, memory_stats, memory_delete, and memory_delete_domain—through its @mnemoverse/mcp-memory-server npm package for MCP-compatible clients. The memory graph visualization shows how memories are stored as nodes, linked through associations, and consolidated over time, reflecting the agent’s evolving knowledge.

Developers and teams can integrate Mnemoverse into their AI agents and tools with minimal setup, leveraging its listing on the official MCP Registry and compatibility with popular development environments. The platform has been benchmarked on public memory benchmarks such as LoCoMo and LongMemEval, with all results linked to committed run artifacts for transparency and reproducibility.

Mnemoverse offers a free tier providing 1,000 queries per day, 10,000 atoms, and 60 requests per minute, with no credit card required. Paid plans include Pro and Team tiers with increased limits and additional features such as priority support and shared domains, as well as custom Enterprise options offering unlimited usage, enhanced security, and compliance features. Early-stage startups may be eligible for extended free access to the Team plan.
