mymore
A category-first, lightweight MCP memory server that provides persistent memory for AI agents using Markdown and SQLite FTS5, with triage classification and consolidation.
README
mymore
分类优先的轻量 MCP 记忆存储系统。
mymore 是一个本地优先的 MCP(Model Context Protocol)记忆服务器,为 AI Agent 提供持久化记忆能力。以 Markdown 为权威源,SQLite FTS5 为检索引擎,支持三分类、时效管理、Frozen Snapshot 前缀缓存优化。

三分类原则
| 分类 | 规则 | 示例 |
|---|---|---|
| persistent | 不可重新推导,跨 session 有效 | 用户偏好、bug 修复、技术决策 |
| session | 短期高价值,跟随 session | 临时变量、中间工具结果 |
| archived | 过时或被替代,保留但排除搜索 | valid_until 过期、superseded |
MCP Tools
| Tool | 功能 |
|---|---|
add_memory |
存储记忆,自动三分类,写入 Markdown + FTS5 |
search_memory |
关键词搜索,支持 owner/track/category 过滤 |
forget_memory |
标记过时/被替代(不删除,保留溯源链) |
consolidate |
归纳:去重、时效淘汰、精华提炼 |

快速开始
# 构建 Docker 镜像
docker build -t mymore-mcp -f apps/mcp-server/Dockerfile .
# 运行 MCP Server(stdio 模式)
docker run -i --rm -v ~/.mymore:/root/.mymore mymore-mcp
首次运行会自动创建 ~/.mymore/ 目录并初始化数据库。
开发模式
# 安装依赖
pnpm install
# 构建
pnpm build
# 运行测试(共 38 个)
pnpm test
