# MCP Odoo Server Improvement Plan
## Based on Reference Implementation Analysis
---
## 🎯 Priority Improvements
### **HIGH PRIORITY**
#### 1. Add API Key Authentication Support
**Missing**: Your implementation only supports username/password
**Reference has**: API key authentication for better security
```python
# Need to add in odoo_client.py:
class AuthMethod(Enum):
PASSWORD = "password"
API_KEY = "api_key"
def authenticate_with_api_key(self, api_key: str) -> bool:
"""Authenticate using API key"""
# Implementation needed
```
#### 2. Implement Health Check Endpoint
**Missing**: No health monitoring
**Reference has**: `get_health_status()` method
```python
# Need to add in server.py:
@mcp.tool()
def get_health_status() -> dict:
"""Get comprehensive system health metrics"""
return {
"status": "healthy",
"connection": "active",
"models_accessible": len(get_accessible_models()),
"uptime": get_uptime()
}
```
#### 3. Better Error Handling Classes
**Current**: Basic exception handling
**Reference has**: Structured exception hierarchy
```python
# Need to create error_handling.py:
class OdooMCPError(Exception):
"""Base exception for Odoo MCP operations"""
pass
class OdooConnectionError(OdooMCPError):
"""Connection-related errors"""
pass
class AccessControlError(OdooMCPError):
"""Access control violations"""
pass
```
#### 4. Configuration Validation with Pydantic Settings
**Current**: Manual config loading
**Reference has**: Automatic validation and environment integration
```python
# Need to enhance config.py:
from pydantic_settings import BaseSettings
class OdooConfig(BaseSettings):
url: str
db: str
username: Optional[str] = None
password: Optional[str] = None
api_key: Optional[str] = None
auth_method: str = "password"
timeout: int = 30
verify_ssl: bool = True
class Config:
env_file = ".env"
env_prefix = "ODOO_"
```
### **MEDIUM PRIORITY**
#### 5. Connection Pooling
**Missing**: Single connection approach
**Reference has**: Connection pooling for performance
#### 6. Access Control Framework
**Missing**: Basic permission checking
**Reference has**: Comprehensive access control system
#### 7. Resource URI Templates
**Missing**: Static resource definitions
**Reference has**: Dynamic URI template system
### **LOW PRIORITY**
#### 8. Error Sanitization
**Current**: Raw error exposure
**Reference has**: Sanitized error messages
#### 9. Smart Field Selection
**Missing**: Manual field specification
**Reference has**: Intelligent field selection

## 🔧 Implementation Steps
### Step 1: Core Infrastructure (Week 1)
#### Add Error Handling Framework
```python
# Create src/odoo_mcp/exceptions.py
class OdooMCPError(Exception):
"""Base exception for all Odoo MCP operations"""
def __init__(self, message: str, error_code: Optional[str] = None):
super().__init__(message)
self.error_code = error_code
class OdooConnectionError(OdooMCPError):
"""Raised when connection to Odoo fails"""
pass
class AccessControlError(OdooMCPError):
"""Raised when access is denied"""
pass
class ValidationError(OdooMCPError):
"""Raised when data validation fails"""
pass
```
#### Enhance Configuration System
```python
# Update src/odoo_mcp/config.py
from pydantic_settings import BaseSettings
from typing import Optional, Literal
class OdooConfig(BaseSettings):
# Connection settings
url: str
db: str
timeout: int = 30
verify_ssl: bool = True
# Authentication
auth_method: Literal["password", "api_key"] = "password"
username: Optional[str] = None
password: Optional[str] = None
api_key: Optional[str] = None
# Performance
connection_pool_size: int = 5
cache_ttl: int = 300
# Security
allowed_models: Optional[list[str]] = None
forbidden_models: list[str] = ["ir.config_parameter"]
class Config:
env_file = ".env"
env_prefix = "ODOO_"
case_sensitive = False
def load_config() -> OdooConfig:
"""Load and validate configuration"""
return OdooConfig()
```
### Step 2: Authentication Enhancement (Week 2)
#### Add API Key Support
```python
# Update src/odoo_mcp/odoo_client.py
from enum import Enum
class AuthMethod(Enum):
PASSWORD = "password"
API_KEY = "api_key"
class OdooClient:
def __init__(self, config: OdooConfig):
self.config = config
self.auth_method = AuthMethod(config.auth_method)
async def authenticate(self) -> bool:
"""Authenticate with Odoo using configured method"""
if self.auth_method == AuthMethod.API_KEY:
return await self._authenticate_api_key()
else:
return await self._authenticate_password()
async def _authenticate_api_key(self) -> bool:
"""Authenticate using API key"""
if not self.config.api_key:
raise OdooConnectionError("API key not provided")
try:
# Validate API key with Odoo
response = await self._call_api_endpoint("/mcp/validate", {
"api_key": self.config.api_key
})
return response.get("valid", False)
except Exception as e:
raise OdooConnectionError(f"API key authentication failed: {e}")
```
### Step 3: Health Monitoring (Week 2)
#### Add Health Check Tool
```python
# Add to src/odoo_mcp/tools/monitoring.py
@mcp.tool()
def get_health_status(
context: Context,
include_details: bool = False
) -> dict:
"""
Get comprehensive system health metrics
Args:
include_details: Include detailed diagnostics
Returns:
Health status information
"""
try:
app_context = context.session
client = app_context.odoo
# Basic health check
health = {
"status": "healthy",
"timestamp": datetime.utcnow().isoformat(),
"connection": "active" if client.is_connected() else "inactive",
"auth_method": client.config.auth_method,
"database": client.config.db
}
if include_details:
health.update({
"uptime": get_server_uptime(),
"models_accessible": len(client.get_accessible_models()),
"memory_usage": get_memory_usage(),
"cache_size": client.get_cache_size(),
"connection_pool": client.get_pool_status()
})
return health
except Exception as e:
return {
"status": "unhealthy",
"error": str(e),
"timestamp": datetime.utcnow().isoformat()
}
```
### Step 4: Access Control (Week 3)
#### Implement Access Controller
```python
# Create src/odoo_mcp/access_control.py
from dataclasses import dataclass
from typing import Set, Dict, List
@dataclass
class ModelPermissions:
"""Permissions for a specific model"""
read: bool = True
write: bool = True
create: bool = True
unlink: bool = True
class AccessController:
"""Manages access control for Odoo operations"""
def __init__(self, config: OdooConfig):
self.config = config
self.model_permissions: Dict[str, ModelPermissions] = {}
self._load_permissions()
def _load_permissions(self):
"""Load model permissions from configuration"""
# Default permissions
default_perms = ModelPermissions()
# Restricted models
restricted_models = [
"ir.config_parameter",
"res.users",
"res.groups"
]
for model in restricted_models:
self.model_permissions[model] = ModelPermissions(
read=False, write=False, create=False, unlink=False
)
def check_model_access(self, model: str, operation: str) -> bool:
"""Check if operation is allowed on model"""
if model in self.config.forbidden_models:
return False
if self.config.allowed_models and model not in self.config.allowed_models:
return False
perms = self.model_permissions.get(model, ModelPermissions())
return getattr(perms, operation, True)
def validate_operation(self, model: str, operation: str):
"""Validate operation or raise AccessControlError"""
if not self.check_model_access(model, operation):
raise AccessControlError(
f"Access denied for {operation} operation on model {model}"
)
```
