memento-mcp

概述

Memento MCP 是一个复杂的知识图谱内存系统，为大型语言模型提供持久、自适应的长期记忆。它使用 Neo4j 作为后端，同时支持图存储和向量搜索功能。系统支持包含丰富元数据的实体、具有置信度评分的关系以及对所有变更的时间跟踪，允许进行特定时间点的查询和历史分析。

FAQ

Memento 与其他记忆系统有什么不同？

Memento 使用基于 Neo4j 的知识图谱方法，提供时间感知、语义搜索和置信度衰减功能，而传统的键值记忆系统不提供这些功能。

我可以在除 Claude Desktop 之外的其他 LLM 客户端上使用它吗？

是的，Memento MCP 支持任何支持模型上下文协议的 LLM 客户端，包括 Cursor 和 GitHub Copilot。
