# Memory Bank MCP - Coding Integration Features ✅ IMPLEMENTED
## ✅ Core Integration Features (COMPLETED)
- **✅ Coding-specific session types**: `coding_session`, `debugging_session`, `architecture_session`
- **✅ Codebase memory storage**: Store API signatures, package structures, existing patterns
- **✅ Package discovery tools**: Auto-scan installed packages and available APIs
- **✅ Validation gates for package usage**: Check if existing APIs are used before writing new code
- **✅ Coding pattern templates**: Store and retrieve coding patterns, API usage examples
## ✅ Package Integration Enforcement (COMPLETED)
- **✅ `validate_package_usage()` tool**: Before any code generation, check if existing packages can handle the task
- **✅ `explore_existing_apis()` tool**: Search through documented APIs and suggest existing solutions
- **✅ `load_codebase_context()` tool**: Load existing codebase structure and patterns into memory
- **✅ `prevent_reinvention_check()` tool**: Warning system when AI tries to rewrite existing functionality
## ✅ Documentation Integration (COMPLETED)
- **✅ Modified `store_memory()` to accept code artifacts**: Store code snippets, API docs, package structures
- **✅ Added `codebase://` resource types**: Access package documentation through MCP resources
- **✅ Coding-specific collection support**: `api_patterns`, `package_structures`, `integration_examples`
- **✅ `discover_packages()` tool**: Automatically load package docs and examples into session
## ✅ Database Schema (IMPLEMENTED)

## 🛠️ New MCP Tools Available
### Session Management
- `create_memory_session(problem, success_criteria, constraints, session_type)` - Create coding-specific sessions
### Package Discovery & Validation
- `discover_packages(scan_imports=True)` - Auto-discover installed packages and APIs
- `validate_package_usage(code_snippet)` - Validate code against existing packages
- `explore_existing_apis(functionality)` - Find existing APIs for needed functionality
- `prevent_reinvention_check(functionality_description)` - Check for potential reinvention
### Code Pattern Management
- `store_codebase_pattern(pattern_type, code_snippet, description, language, file_path, tags)` - Store code patterns
- `load_codebase_context(project_path)` - Load project structure into memory
- `store_memory(content, ..., code_snippet, language, pattern_type)` - Enhanced memory storage with code
### Resources
- `codebase://packages` - View discovered packages in current session
- `codebase://patterns` - View stored codebase patterns
- `codebase://validation-checks` - View validation check history
## 🚀 Usage Examples
### 1. Start a Coding Session
```python
create_memory_session(
"Implement user authentication system",
"Secure, scalable auth with existing libraries",
"Use OAuth, avoid custom crypto",
"coding_session"
)
```
### 2. Discover Available Packages
```python
discover_packages() # Scans environment for packages
```
### 3. Validate Code Before Implementation
```python
validate_package_usage("""
def hash_password(password):
import hashlib
return hashlib.sha256(password.encode()).hexdigest()
""")
# Returns: Warning - Consider using bcrypt or scrypt for password hashing
```
### 4. Check for Reinvention
```python
prevent_reinvention_check("HTTP client for REST APIs")
# Returns: Found existing APIs: requests.get(), urllib3.request(), etc.
```
### 5. Store Code Patterns
```python
store_codebase_pattern(
"api_usage",
"import requests\nresponse = requests.get(url, headers=headers)",
"Standard HTTP GET request pattern",
"python",
"api_client.py",
"http,api,requests"
)
```
## 🎯 Integration Benefits
1. **Prevents Package Reinvention**: Automatically suggests existing libraries
2. **Code Pattern Reuse**: Store and retrieve proven code patterns
3. **API Discovery**: Auto-discover available packages and their capabilities
4. **Validation Gates**: Catch potential issues before implementation
5. **Project Context**: Load existing codebase structure for better decisions
6. **Session Isolation**: Project-specific package and pattern storage
## 🔄 Migration
- Existing sessions remain compatible
- New tables added automatically
- Backward compatibility maintained
- Enhanced functionality available immediately
