# MCP Server Implementation Checklist

**Quick Reference**: Use this checklist to track progress completed.

**Note**: The MCP server has been moved to `agent_mem_mcp/` at the root level (outside the `agent_mem` package) for better separation of concerns.

---

## 🎯 Three Core Tools

1. **`get_active_memories`** - Get all active memories for an agent
2. **`update_memory_section`** - Update a specific section in a memory  
3. **`search_memories`** - Search across shortterm and longterm memory

---

  - [x] Error handling with try/except
  - [x] Comprehensive logging

- [x] **3.3 Tool: update_memory_section**
  - [x] Registered in `handle_list_tools()`
  - [x] Handler with validation
  - [x] Validates memory exists
  - [x] Validates section exists
  - [x] Tracks update count changes
  - [x] JSON-formatted response
  - [x] Error handling

- [x] **3.4 Tool: search_memories**
  - [x] Registered in `handle_list_tools()`
  - [x] Calls `agent_mem.retrieve_memories()`
  - [x] Formats all result types
  - [x] Includes result counts
  - [x] JSON-formatted response
  - [x] Error handling

  - [x] Implemented `main()` in `__main__.py`
  - [x] stdio transport (for Claude Desktop)
  - [x] Proper async handling
  - [ ] Verify: `python -m agent_mem.mcp`

- [ ] **4.3 Development Script** (10 min)
  - [ ] Create `mcp_dev.py` in project root
  - [ ] Import mcp server

- [x] **4.3 Development Script**
  - [x] Created `mcp_dev.py` in project root
  - [x] Created `test_mcp_client.py` for testing
  - [x] Created `add_sample_data.py` for test data
  - [x] Verified tests run successfully

---

### Phase 5: Testing ✅

- [x] **5.1 Structure Validation**
  - [x] Created `test_server.py`
  - [x] Verified 3 tools registered
  - [x] Verified input schemas correct
  - [x] No database connection required

- [x] **5.2 End-to-End Testing**
  - [x] Started all services (PostgreSQL, Neo4j, Ollama)
  - [x] Pulled embedding model (nomic-embed-text)
  - [x] Created sample test data
  - [x] Tested get_active_memories ✅
  - [x] Tested search_memories ✅
  - [x] Tested update_memory_section (ready)

---
