Overview

Description from the maker (original English)

情景+实体记忆 MCP 服务,为 Claude Code 提供持久化记忆能力

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: CLAUDE_PROJECT_ROOT

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "memory": {
      "command": "uvx",
      "args": [
        "chenxiaofie-memory-mcp"
      ],
      "env": {
        "CLAUDE_PROJECT_ROOT": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add memory --env CLAUDE_PROJECT_ROOT=your-value -- uvx chenxiaofie-memory-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "memory": {
      "command": "uvx",
      "args": [
        "chenxiaofie-memory-mcp"
      ],
      "env": {
        "CLAUDE_PROJECT_ROOT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "memory": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "chenxiaofie-memory-mcp"
      ],
      "env": {
        "CLAUDE_PROJECT_ROOT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • CLAUDE_PROJECT_ROOT env
    项目根目录路径

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Common questions

Is Memory MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Memory MCP Service

English | 中文

A persistent memory MCP service for Claude Code. Automatically saves conversations and retrieves relevant history across sessions.

What it does: Every time you chat with Claude Code, your conversation context (decisions, preferences, key discussions) is saved and automatically recalled in future sessions — so Claude always has the background it needs.

Quick Start

Prerequisites

Install uv (Python package runner):

# Windows

powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

Mac/Linux

curl -LsSf https://astral.sh/uv/install.sh | sh

Requires Python 3.10 - 3.13 (chromadb is not compatible with Python 3.14+).

1. Initialize (First Time Only)

Download the vector model (~400MB, one-time):

uvx --from chenxiaofie-memory-mcp memory-mcp-init
2. Add MCP Server to Claude Code
claude mcp add memory-mcp -s user -- uvx --from chenxiaofie-memory-mcp memory-mcp
3. Configure Hooks (Recommended)

Hooks enable fully automatic message saving. Without hooks, you need to manually call memory tools.

Add the following to ~/.claude/settings.json:

{

"hooks": { "SessionStart": [{ "matcher": ".*", "hooks": [{ "type": "command", "command": "uvx --from chenxiaofie-memory-mcp memory-mcp-session-start" }] }], "UserPromptSubmit": [{ "matcher": ".*", "hooks": [{ "type": "command", "command": "uvx --from chenxiaofie-memory-mcp memory-mcp-auto-save" }] }], "Stop": [{ "matcher": ".*", "hooks": [{ "type": "command", "command": "uvx --from chenxiaofie-memory-mcp memory-mcp-save-response" }] }], "SessionEnd": [{ "matcher": ".*", "hooks": [{ "type": "command", "command": "uvx --from chenxiaofie-memory-mcp memory-mcp-session-end" }] }] } }

4. Verify
claude mcp list

You should see memory-mcp: ... - ✓ Connected.

That's it! Start a new Claude Code session and your conversations will be automatically saved and recalled.

How It Works

Session Start ──► Create Episode ──► Monitor Process (background)

│ User Message ──► Save Message ──► Recall Related Memories ──► Inject Context │ Claude Reply ──► Save Response │ │ Session End ──► Close Signal ──► Archive Episode + Generate Summary

  • Episodes: Each conversation session is an "episode" with auto-generated summaries
  • Entities: Key knowledge extracted from conversations (decisions, preferences, concepts)
  • Dual-layer storage: User-level (shared across projects) + Project-level (isolated per project)
  • Semantic search: Vector-based retrieval finds relevant past context

Usage

Automatic Mode (With Hooks)

Once hooks are configured, everything is automatic. Claude will see relevant history from past sessions as context.

Manual Mode

You can also call memory tools directly in Claude Code:

# Start a new episode

memory_start_episode("Login Feature Development", ["auth"])

Record a decision

memory_add_entity("Decision", "Use JWT + Redis", "For distributed deployment")

Search history

memory_recall("login implementation")

Close episode

memory_close_episode("Completed JWT login feature")

Hooks Reference

Storage Locations

  • User-level: ~/.claude-memory/
  • Project-level: {project-root}/.claude/memory/

Alternative: Install from source

If you need to run from source (e.g., for development):

git clone https://github.com/chenxiaofie/memory-mcp.git

cd memory-mcp

Windows:

install.bat

Mac/Linux:

chmod +x install.sh && ./install.sh

Then configure MCP server with the venv Python:

# Windows:

claude mcp add memory-mcp -s user -- "C:\path\to\memory-mcp\venv310\Scripts\python.exe" -m memory_mcp.server

Mac/Linux:

claude mcp add memory-mcp -s user -- /path/to/memory-mcp/venv310/bin/python -m memory_mcp.server
