MegaMemory

概述

MegaMemory 允许编程代理在会话之间构建和查询概念、架构和决策的图谱。它使用 LLM 生成的概念而非 AST 解析，在 SQLite 中持久化知识图谱。服务器提供了理解项目上下文、创建/更新概念、管理关系和解决不同版本知识图谱之间合并冲突的工具。它包含用于可视化的 Web 浏览器，并支持多个 MCP 客户端。

装完之后，这里有 5 个你可以让 AI 做的事：

• understand

  Semantic search over the knowledge graph. Returns matched concepts with children, edges, and parent context.

  试试:Find all modules related to authentication试试:Search for concepts about database indexing patterns
• get_concept

  Look up a concept by its exact ID. Returns full context including children, edges, incoming edges, and parent.

  试试:Get concept with ID user-auth-module试试:Retrieve concept details for payment-processing-2023
• create_concept

  Add a new concept with optional edges and file references.

  试试:Create a new concept for the user authentication feature试试:Add a concept about the new caching implementation
• update_concept

  Update fields on an existing concept. Regenerates embeddings automatically.

  试试:Update the concept about the payment processor to include new error handling试试:Modify the user session concept to add references to auth files
• link

  Create a typed relationship between two concepts.

  试试:Link the auth concept to the user database concept with depends_on relationship试试:Connect the payment module to the notification system with calls relationship
• remove_concept

  Soft-delete a concept with a reason. History preserved.

  试试:Remove the deprecated concept old-login-system because it's been replaced试试:Delete the concept about abandoned feature X
• list_roots

  List all top-level concepts with direct children.

  试试:Show all top-level concepts试试:List the main architecture components
• list_conflicts

  List unresolved merge conflicts grouped by merge group.

  试试:Show all merge conflicts试试:List conflicts in the knowledge graph
• resolve_conflict

  Resolve a merge conflict by providing verified, correct content based on the current codebase.

  试试:Resolve conflict for user management module with correct implementation试试:Fix the merge conflict for payment processing with current code

FAQ

MegaMemory 如何存储知识？

它使用 SQLite WAL 模式存储，将概念作为节点，关系作为边。每个项目都有自己的数据库，位于 .megamemory/knowledge.db。

它是否需要 API 密钥或网络调用？

不需要，嵌入处理在内存中进行，使用 all-MiniLM-L6-v2 模型（下载一次约 23MB），无需 API 密钥。
