## 🎯 What We Built

### MCP Server Implementation

**Location**: `agent_mem_mcp/`

**Architecture**: Low-level Server API (mcp.server.lowlevel.Server)

**Files**:
- `server.py` (320 lines) - Main server with lifespan management
- `schemas.py` (75 lines) - JSON Schema definitions
- `run.py` - Simple runner script
- `test_server.py` - Structure validation
- `__main__.py` - CLI entry point
- `README.md` - Comprehensive documentation

### Three Tools (All Working ✅)

1. **`get_active_memories`**
   - Input: `{"external_id": "agent-id"}`
   - Returns: All active memories with sections
   - Status: ✅ Tested successfully

2. **`update_memory_sections`** (Batch Update)
   - Input: `{"external_id": "agent-id", "memory_id": 3, "sections": [{"section_id": "task", "new_content": "..."}]}`
   - Returns: Updated memory with update count tracking for each section
   - Status: ✅ Tested successfully

3. **`search_memories`**
   - Input: `{"external_id": "agent-id", "query": "...", "search_shortterm": true, "search_longterm": true, "limit": 10}`
   - Returns: Synthesized response + matched chunks + entities + relationships
   - Status: ✅ Tested successfully

## 🚀 How to Use

### Option 1: Test with MCP Client Script

```powershell
# Run the test client
py test_mcp_client.py
```

### Option 2: Test with MCP Inspector

```powershell
# Start MCP Inspector (opens web UI)
mcp dev mcp_dev.py

# Then open browser at the URL shown
# You can interactively test all 3 tools
```

### Option 3: Integrate with Claude Desktop

**Step 1**: Edit Claude Desktop config

File location: `%APPDATA%\Claude\claude_desktop_config.json`

**Step 2**: Add configuration:

```json
{
  "mcpServers": {
    "agent-mem": {
      "command": "py",
      "args": ["-m", "agent_mem_mcp"],
      "env": {
        "POSTGRES_HOST": "localhost",
        "POSTGRES_PORT": "5432",
        "POSTGRES_USER": "postgres",
        "POSTGRES_PASSWORD": "postgres",
        "POSTGRES_DB": "agent_mem",
        "NEO4J_URI": "bolt://localhost:7687",
        "NEO4J_USER": "neo4j",
        "NEO4J_PASSWORD": "neo4jpassword",
        "OLLAMA_BASE_URL": "http://localhost:11434",
        "GEMINI_API_KEY": "AIzaSyCD7ZhcN-srbeCxG8d9r0NGKeuufpOguHo"
      }
    }
  }
}
```

**Step 3**: Restart Claude Desktop

**Step 4**: Use in conversation:

- "Get my active memories for agent test-agent-123"
- "Update the current_task section with new content"
- "Search my memories for JWT authentication best practices"

## 🎓 Key Technical Decisions

### 1. Low-Level Server API
✅ **Why**: Explicit control over schemas, no FastMCP abstractions
✅ **Benefit**: Full visibility into tool registration and execution

### 2. Separated from Core Package
✅ **Why**: MCP server is a separate concern from core AgentMem
✅ **Benefit**: Clean separation, easier to maintain and test

### 3. Stateless Design with external_id
✅ **Why**: Single AgentMem instance serves multiple agents
✅ **Benefit**: Efficient resource usage, scales well

### 4. JSON Schema for Inputs
✅ **Why**: Explicit validation before execution
✅ **Benefit**: Clear error messages, better developer experience

### 5. stdio Transport
✅ **Why**: Standard for MCP, works with Claude Desktop
✅ **Benefit**: Wide compatibility, simple integration
