Strata Memory MCP Server is a layered memory system for AI agents with SQLite as source of truth, rebuildable vector index, and Markdown projection. You can:
Initialize/configure: set personal or company mode, embedding model/provider, CBT safety, and apply config with hot reload.
Store and promote memories: commit validated facts, preferences, procedures, episodes with metadata; promote session scratchpad to durable storage.
Recall and search: progressive context recall, hybrid vector+FTS5 semantic search with filters, and expand memory details by ID.
Manage and maintain: run health checks, rebuild vector index, view L0-L3 stats/watermarks, export Markdown, and run digest/hygiene for expired, duplicate, or secret data.
Optimize hardware/config: profile system hardware, get embedding recommendations, and apply memory configuration without restart.
Enforce safety and isolation: Quality Kernel blocks passwords, API keys, vague timestamps, and unverified claims; scoped by tenant, user, and session; company mode includes audit logging.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Strata Memory MCP Server memorize key points from today's meeting about Q3 roadmap"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
大模型只做决策，确定性代码接管一切。
Strata Memory 2.0 是面向 Multi-Agent 的 MCP 记忆中枢：以 SQLite 为唯一真相源（SoT），向量库可一键重建，Markdown 仅为只读投影。写入经过 Quality Kernel / CBT 中间件；召回采用渐进式漏斗，避免上下文爆炸。
层 | 角色 | 可摧毁？ |
SQLite Truth Store | 权威数据（记忆 / 审计 / 轨迹） | 否（备份） |
Chroma + BGE-M3 | 语义索引伴生层 | 是 — |
Markdown projection | 人类可读视图 | 是 — |
L0–L3 分层 + 类型化 TTL（事实/偏好/规程/情节）
三维隔离：tenant_id + user_id + session_id
Scratch → Durable：会话暂存，确认后 promote_session
防御性 MCP 契约：工具描述强制「作用 / 触发 / 禁忌」
