安全提示

MCP 服务会接收对话中的工具调用请求，并可能执行外部操作。启用前请先了解该服务能做什么，并只授予它所需的权限。

概览

AI 生成的概览

为 AI 助手提供托管式持久语义记忆：按语义存储与检索记忆、建立知识图谱，并恢复会话身份。

可以做什么: 存储、按语义检索、关联和删除记忆，并查看记忆统计与会话上下文摘要
在会话开始与结束时恢复身份、保存会话状态
浏览并启用 Intelligence Pack，将精选领域知识导入记忆库
适用场景: 适合需要助手跨会话记住偏好、决策和项目背景的场景，或希望直接加载预置领域知识而不必自行积累。若只是一次性对话、无需持久化，则意义不大。
运行要求: 通过 npx 在本地运行（需 Node.js）。需要以 mnx_ 开头的 NEXUS_API_KEY，可从 7 天免费试用或付费套餐获取；可选 NEXUS_API_URL 覆盖默认托管 API。需能访问厂商 API 的网络。

安装前请注意

该服务器只是瘦客户端，记忆保存在厂商服务器而非本地，被记住的内容会离开你的机器。付费套餐为每月 19 至 149 美元，试用需提供邮箱。remember、connect、forget、wear_hat 和 hibernate 都会写入或删除账户中的数据。

安装

在 SourceWeft 中

打开控制台中的 Nexus Memory Mcp，将其添加到工作区。
为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照仓库中的启动说明。

README

Nexus Memory MCP

Persistent semantic memory for AI agents. Remember everything, recall by meaning, grow smarter over time.

The only memory system with pre-built Intelligence Packs (domain expertise you can activate instantly).

Install

One command. Works with Claude Code, Cursor, Windsurf, or any MCP-compatible client.

Claude Code / Cursor / Windsurf

Add to your .mcp.json:

json

{  "mcpServers": {    "nexus-memory": {      "command": "npx",      "args": ["-y", "nexus-memory-mcp"],      "env": {        "NEXUS_API_KEY": "mnx_your_api_key_here"      }    }  }}

{  "mcpServers": {    "nexus-memory": {      "command": "npx",      "args": ["-y", "nexus-memory-mcp"],      "env": {        "NEXUS_API_KEY": "mnx_your_api_key_here"      }    }  }}

Tools

Core Memory

Tool	Description
`remember`	Store a memory with context, importance, and metadata
`recall`	Semantic search across all memories (by meaning, not keywords)
`connect`	Create relationships between memories (build knowledge graphs)
`forget`	Remove a memory
`stats`	Memory statistics
`context`	Session context summary (preferences, decisions, patterns)

Agent Self-Continuity

Intelligence Packs

How It Works

Remember stores memories with semantic embeddings. Recall finds them by meaning.

Session 1:  remember("Diana prefers bold solutions over phased approaches")Session 47: recall("how does Diana like things done?")            -> "Diana prefers bold solutions over phased approaches" (92% match)

Session 1:  remember("Diana prefers bold solutions over phased approaches")Session 47: recall("how does Diana like things done?")            -> "Diana prefers bold solutions over phased approaches" (92% match)

Intelligence Packs give your agent instant domain expertise:

list_hats()    -> DevOps Expert (103 memories), TCM Specialist (200+ memories), ...wear_hat("devops-expert")recall("how to set up zero-downtime deploys?")  -> Expert knowledge from 103 curated DevOps memories

list_hats()    -> DevOps Expert (103 memories), TCM Specialist (200+ memories), ...wear_hat("devops-expert")recall("how to set up zero-downtime deploys?")  -> Expert knowledge from 103 curated DevOps memories

Awaken/Hibernate gives your agent identity continuity:

// Start of sessionawaken()  -> "I remember. Session 47. I was refactoring the auth module."
// End of sessionhibernate({ working_on: "auth refactor", learnings: "JWT refresh tokens need..." })

// Start of sessionawaken()  -> "I remember. Session 47. I was refactoring the auth module."
// End of sessionhibernate({ working_on: "auth refactor", learnings: "JWT refresh tokens need..." })

Architecture

This MCP server is a thin client. All intelligence lives on our servers:

Your Agent  <->  nexus-memory-mcp  <->  Nexus Memory API (Railway)                 (thin MCP client)      (semantic engine, knowledge graphs,                                         pattern learning, Intelligence Packs)

Your Agent  <->  nexus-memory-mcp  <->  Nexus Memory API (Railway)                 (thin MCP client)      (semantic engine, knowledge graphs,                                         pattern learning, Intelligence Packs)

Your data is isolated per API key. Multi-tenant, encrypted at rest.
