Soul MCP Server Adds Persistent Memory and Safety for Local LLMs

What Soul Does

Soul is an open-source MCP server designed to solve the session memory problem for local LLMs. By using two simple commands, it enables agents to remember everything across sessions instead of forgetting at the end of each session.

Key Features

• Persistent Memory: Two commands control memory persistence: n2_boot at session start and n2_work_end at session end
• Ark Safety System: Built-in safety that blocks dangerous commands like rm -rf and DROP DATABASE at zero token cost
• Cloud Storage: Configurable cloud storage with one line of configuration
• Open Source: Released under Apache-2.0 license

Setup with Ollama + Open WebUI

Installation and configuration steps:

1. Install via npm: npm install n2-soul
2. In Open WebUI, go to Settings → Tools → MCP Servers
3. Add a new server with command set to "node"
4. Set args to your path to node_modules/n2-soul/index.js

The server also works with LM Studio and Cursor.
