# AgenticMemory MCP Server

> Universal LLM access to persistent graph memory via the Model Context Protocol.

AgenticMemory MCP Server bridges **any MCP-compatible LLM client** (Claude, GPT, Gemini, Ollama, etc.) to the AgenticMemory persistent binary graph memory system. One server, universal access.

```

## Quick Start

### Install from crates.io

```bash
cargo install agentic-memory-mcp
```

### Or build from source

```bash
cargo build --release
```

### Run (stdio transport — default)

```bash
agentic-memory-mcp serve
```

> Zero-config: defaults to `~/.brain.amem`. Override with `agentic-memory-mcp --memory /path/to/brain.amem serve`.

### Memory Modes

Control how aggressively Claude saves memories:

```bash
agentic-memory-mcp serve --mode minimal   # Only save when user says "remember"
agentic-memory-mcp serve --mode smart     # Auto-save facts + decisions (default)
agentic-memory-mcp serve --mode full      # Save everything, episode summaries
```

| Mode | Saves Per Conversation | File Growth | Best For |
|:---|---:|---:|:---|
| **minimal** | 1-3 | ~1 KB/day | Privacy-conscious users |
| **smart** | 5-15 | ~5-20 KB/day | Most users (default) |
| **full** | 15-30+ | ~20-50 KB/day | Power users, autonomous agents |

Configure via the `args` array in your MCP config:

```json
{ "command": "agentic-memory-mcp", "args": ["serve", "--mode", "full"] }
```

### Run (SSE transport)

```bash
cargo build --release --features sse
agentic-memory-mcp serve-http --addr 127.0.0.1:3000
```

## Configuration with MCP Clients

### Claude Desktop

Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "agentic-memory": {
      "command": "agentic-memory-mcp",
      "args": ["serve"]
    }
  }
}
```

### Claude Code

Add to `~/.claude/mcp.json`:

```json
{
  "mcpServers": {
    "agentic-memory": {
      "command": "agentic-memory-mcp",
      "args": ["serve"]
    }
  }
}
```

### VS Code / Cursor

Add to `.vscode/settings.json`:

```json
{
  "mcp.servers": {
    "agentic-memory": {
      "command": "agentic-memory-mcp",
      "args": ["serve"]
    }
  }
}
```

### Windsurf

Add to `~/.codeium/windsurf/mcp_config.json`:

```json
{
  "mcpServers": {
    "agentic-memory": {
      "command": "agentic-memory-mcp",
      "args": ["serve"]
    }
  }
}
```

> Zero-config: defaults to `~/.brain.amem`. Override with `"args": ["--memory", "/path/to/brain.amem", "serve"]`.

## CLI Commands

```bash
# Start server (stdio) — defaults to ~/.brain.amem
agentic-memory-mcp serve

# Start server with custom memory file
agentic-memory-mcp --memory /path/to/brain.amem serve

# Start server (SSE, requires --features sse)
agentic-memory-mcp serve-http --addr 127.0.0.1:3000

# Validate a memory file
agentic-memory-mcp --memory ~/.brain.amem validate

# Print server info as JSON
agentic-memory-mcp info
```

## Development

This crate is part of the [AgenticMemory](../../README.md) Cargo workspace.

```bash
# Run MCP server tests (from workspace root)
cargo test -p agentic-memory-mcp

# Run bridge integration tests
cargo test -p agentic-memory-bridge-tests
