memcp

概述

MemCP 是一个精密的 MCP 服务器，为 Claude Code 提供持久化外部记忆系统。它解决了 /compact 命令后和会话达到上下文窗口限制时的上下文丢失问题。该服务器实现了 24 个 MCP 工具，分布在记忆管理、上下文处理、搜索、图导航和生命周期管理等类别中。它使用 SQLite 进行存储，并采用 MAGMA 4 图系统，通过语义、时间、因果和实体边连接洞察。架构遵循三层委托模式，具有全面的测试覆盖和基准测试，显示出比原生仅上下文操作显著的代币效率优势。

FAQ

MemCP 如何防止 /compact 后的上下文丢失？

MemCP 实现自动保存钩子，强制 Claude 在压缩前保存洞察，将其存储在 SQLite 中以便跨会话检索。

MemCP 使用什么文件存储？

MemCP 使用 SQLite 进行知识图存储（graph.db）和文件系统进行上下文和块存储（~/.memcp/）。
