### Description (declared)

# NexMem MCP

**Shared Agent Memory for Teams** — a plug-and-play MCP memory server with pluggable database backends.

NexMem gives AI coding agents (Cursor, Claude Desktop, etc.) a persistent knowledge graph that the whole team shares. Agents learn as they work — discovering services, architecture patterns, and conventions — then recall that knowledge instantly in future sessions.

## Features

- **Self or Team memory** — personal graph or shared team graph, switchable via env var
- **5 storage backends** — JSONL (default), SQLite, MongoDB, PostgreSQL, Redis
- **Atomic operations** — no race conditions when multiple team members write simultaneously
- **Strong consistency** — reads always return the latest state
- **Wire-compatible** — same JSONL format as `@modelcontextprotocol/server-memory` for import/export
- **Guided autonomous** — built-in instructions tell the agent what to save (and what not to)
- **Extensible** — add custom backends by implementing the `StorageAdapter` ABC

## Quick Start

### 1. Install

```bash
pip install mcp-nexmem
```

Or with a database backend:

```bash
pip install "mcp-nexmem[mongodb]"   # MongoDB
pip install "mcp-nexmem[postgres]"  # PostgreSQL
pip install "mcp-nexmem[redis]"     # Redis
pip install "mcp-nexmem[all]"       # All backends
```

### 2. Configure

Add to your `~/.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "nexmem": {
      "command": "nexmem-mcp",
      "env": {
        "NEXMEM_MODE": "self"
      }
    }
  }
}
```

### 3. Restart your IDE

That's it. The agent now has persistent memory.

## Interactive Setup

For a guided setup that generates the config for you:

```bash
nexmem-mcp init
```

Or run the install script:

```bash
bash scripts/install.sh
```

## Configuration Reference

All configuration is via environment variables (prefix: `NEXMEM_`):

| Variable | Default | Description |
|---|---|---|
| `NEXMEM_MODE` | `self` | `self` for personal memory, `team` for shared |
| `NEXMEM_USER_NAME` | OS username…
