#### Web Integration with FastMCP

The FastMCP server provides HTTP and SSE transports for web application integration:

##### HTTP Transport for Web APIs

```python
import aiohttp
import json

async def call_d365fo_api():
"""Example: Using HTTP transport for web API integration"""

# Start FastMCP server with HTTP transport
# d365fo-fastmcp-server --transport http --port 8000

mcp_request = {
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "d365fo_query_entities",
"arguments": {
"entityName": "CustomersV3",
"top": 10,
"select": ["CustomerAccount", "Name"]
}
}
}

async with aiohttp.ClientSession() as session:
async with session.post(
"http://localhost:8000/mcp",
json=mcp_request,
headers={"Content-Type": "application/json"}
) as response:
result = await response.json()
print(json.dumps(result, indent=2))
```

##### SSE Transport for Real-time Applications

```javascript
// Example: JavaScript client for real-time D365FO data
// Start FastMCP server: d365fo-fastmcp-server --transport sse --port 8001

const eventSource = new EventSource('http://localhost:8001/sse');

eventSource.onmessage = function(event) {
const data = JSON.parse(event.data);
console.log('Received D365FO data:', data);

// Handle real-time updates from D365FO
if (data.method === 'notification') {
updateDashboard(data.params);
}
};

// Send MCP requests via SSE
function queryCustomers() {
const request = {
jsonrpc: "2.0",
id: Date.now(),
method: "tools/call",
params: {
name: "d365fo_search_entities",
arguments: {
pattern: "customer",
limit: 50
}
}
};

fetch('http://localhost:8001/sse/send', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: JSON.stringify(request)
});
}
```

#### Alternative: Programmatic Usage

```python
from d365fo_client.mcp import D365FOMCPServer

# Create and run server with custom configuration
config = {
"default_environment": {
"base_url": "https://your-environment.dynamics.com",
"use_default_credentials": True
}
}

server = D365FOMCPServer(config)
await server.run()
```

#### Custom MCP Clients
Connect using any MCP-compatible client library:

```python
from mcp import Client

async with Client("d365fo-fastmcp-server") as client:
# Discover available tools
tools = await client.list_tools()

# Execute operations
result = await client.call_tool(
"d365fo_query_entities",
{"entityName": "Customers", "top": 5}
)
```

customer_entities = await client.search_entities("customer")
print(f"Found {len(customer_entities)} customer entities")

# Get customers with query options
from d365fo_client import QueryOptions
options = QueryOptions(
select=["CustomerAccount", "Name", "SalesCurrencyCode"],
top=10,
orderby=["Name"]
)

customers = await client.get_data("/data/CustomersV3", options)
print(f"Retrieved {len(customers['value'])} customers")

if __name__ == "__main__":
asyncio.run(main())
```

### Using Convenience Function

```python
from d365fo_client import create_client

# Quick client creation with enhanced defaults
async with create_client("https://your-fo-environment.dynamics.com") as client:
customers = await client.get_data("/data/CustomersV3", top=5)
```

## Configuration

### Environment Variable Management (New in v0.3.0)

The d365fo-client now includes a comprehensive **Pydantic settings model** for type-safe environment variable management:

```python
from d365fo_client import D365FOSettings, get_settings

# Get type-safe settings instance
settings = get_settings()

# Access settings with full IntelliSense support
print(f"Base URL: {settings.base_url}")
print(f"Log Level: {settings.log_level}")
print(f"Cache Directory: {settings.cache_dir}")

# Check configuration state
if settings.has_client_credentials():
print("Client credentials configured")

startup_mode = settings.get_startup_mode() # "profile_only", "default_auth", "client_credentials"

# Convert to environment dictionary for external tools
env_vars = settings.to_env_dict()
```

**Key Benefits:**
- **Type Safety**: Automatic validation and type conversion for all 35+ environment variables
- **IDE Support**: Full IntelliSense and autocompletion for configuration options
- **Environment Files**: Support for `.env` files in development
- **Comprehensive Defaults**: Sensible defaults for all configuration options
- **Validation**: Built-in validation for URLs, ports, timeouts, and other settings

### Authentication Options

```python
from d365fo_client import FOClientConfig

# Option 1: Default Azure credentials (recommended)
config = FOClientConfig(
base_url="https://your-fo-environment.dynamics.com",
use_default_credentials=True
)

# Option 2: Client credentials
config = FOClientConfig(
base_url="https://your-fo-environment.dynamics.com",
client_id="your-client-id",
client_secret="your-client-secret",
tenant_id="your-tenant-id",
use_default_credentials=False
)

# Option 3: Azure Key Vault integration (New in v0.2.3)
config = FOClientConfig(
base_url="https://your-fo-environment.dynamics.com",
credential_source="keyvault", # Use Azure Key Vault for credentials
keyvault_url="https://your-keyvault.vault.azure.net/"
)

# Option 4: With custom settings
config = FOClientConfig(
base_url="https://your-fo-environment.dynamics.com",
use_default_credentials=True,
verify_ssl=False, # For development environments
timeout=60, # Request timeout in seconds
metadata_cache_dir="./my_cache", # Custom cache directory
use_label_cache=True, # Enable label caching
label_cache_expiry_minutes=120 # Cache for 2 hours
)
```

### Legacy Configuration Migration (New in v0.3.0)

The d365fo-client automatically detects and migrates legacy configuration files:

- **Automatic Detection**: Identifies legacy configuration patterns (missing `verify_ssl`, outdated field names)
- **Field Migration**: Updates `cache_dir` โ†’ `metadata_cache_dir`, `auth_mode` โ†’ `use_default_credentials`
- **Backup Creation**: Creates backup of original configuration before migration
- **Seamless Upgrade**: Ensures smooth transition from older versions without manual intervention

```python
# Legacy configurations are automatically migrated when FastMCP server starts
# No manual intervention required - migration happens transparently
```

## Core Operations

### CRUD Operations

```python
async with D365FOClient(config) as client:
# CREATE - Create new customer (supports composite keys)
new_customer = {
"CustomerAccount": "US-999",
"Name": "Test Customer",
"SalesCurrencyCode": "USD"
}
created = await client.create_data("/data/CustomersV3", new_customer)

# READ - Get single customer by key
customer = await client.get_data("/data/CustomersV3('US-001')")

# UPDATE - Update customer with optimistic concurrency
updates = {"Name": "Updated Customer Name"}
updated = await client.update_data("/data/CustomersV3('US-001')", updates)

# DELETE - Delete customer
success = await client.delete_data("/data/CustomersV3('US-999')")
print(f"Delete successful: {success}")
```

### Advanced Querying

```python
from d365fo_client import QueryOptions

# Complex query with multiple options
options = QueryOptions(
select=["CustomerAccount", "Name", "SalesCurrencyCode", "CustomerGroupId"],
filter="SalesCurrencyCode eq 'USD' and contains(Name, 'Corp')",
expand=["CustomerGroup"],
orderby=["Name desc", "CustomerAccount"],
top=50,
skip=10,
count=True
)

result = await client.get_data("/data/CustomersV3", options)
print(f"Total count: {result.get('@odata.count')}")
```

### Action Execution

```python
# Unbound action
result = await client.post_data("/data/calculateTax", {
"amount": 1000.00,
"taxGroup": "STANDARD"
})

# Bound action on entity set
result = await client.post_data("/data/CustomersV3/calculateBalances", {
"asOfDate": "2024-12-31"

# Intelligent metadata synchronization (v2 system)
sync_manager = await client.get_sync_manager()
await sync_manager.smart_sync()

# Search entities with enhanced filtering
sales_entities = await client.search_entities("sales")
print("Sales-related entities:", [e.name for e in sales_entities])

# Get detailed entity information with labels
entity_info = await client.get_public_entity_info("CustomersV3")
if entity_info:
print(f"Entity: {entity_info.name}")
print(f"Label: {entity_info.label_text}")
print(f"Data Service Enabled: {entity_info.data_service_enabled}")

# Search actions with caching
calc_actions = await client.search_actions("calculate")
print("Calculation actions:", [a.name for a in calc_actions])

# Get enumeration information
enum_info = await client.get_public_enumeration_info("NoYes")
if enum_info:
print(f"Enum: {enum_info.name}")
for member in enum_info.members:
print(f" {member.name} = {member.value}")
```

### Label Operations

```python
# Get specific label (v2 caching system)
label_text = await client.get_label_text("@SYS13342")
print(f"Label text: {label_text}")

# Get multiple labels efficiently
labels = await client.get_labels_batch([
"@SYS13342", "@SYS9490", "@GLS63332"
])
for label_id, text in labels.items():
print(f"{label_id}: {text}")

# Enhanced entity info with resolved labels
entity_info = await client.get_public_entity_info_with_labels("CustomersV3")
if entity_info.label_text:
print(f"Entity display name: {entity_info.label_text}")

# Access enhanced properties with labels
for prop in entity_info.enhanced_properties[:5]:
if hasattr(prop, 'label_text') and prop.label_text:
print(f"{prop.name}: {prop.label_text}")
```

## Error Handling

```python
from d365fo_client import D365FOClientError, AuthenticationError, ConnectionError

try:
async with D365FOClient(config) as client:
customer = await client.get_data("/data/CustomersV3('NON-EXISTENT')")
except ConnectionError as e:
print(f"Connection failed: {e}")
except AuthenticationError as e:
print(f"Authentication failed: {e}")
except D365FOClientError as e:
print(f"Client operation failed: {e}")
print(f"Status code: {e.status_code}")
print(f"Response: {e.response_text}")
```

## Configuration Options

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `base_url` | str | Required | D365 F&O base URL |
| `client_id` | str | None | Azure AD client ID |
| `client_secret` | str | None | Azure AD client secret |
| `tenant_id` | str | None | Azure AD tenant ID |
| `use_default_credentials` | bool | True | Use Azure Default Credential |
| `credential_source` | str | "environment" | Credential source: "environment", "keyvault" |
| `keyvault_url` | str | None | Azure Key Vault URL for credential storage |
| `verify_ssl` | bool | False | Verify SSL certificates |
| `timeout` | int | 30 | Request timeout in seconds |
| `metadata_cache_dir` | str | Platform-specific user cache | Metadata cache directory |
| `use_label_cache` | bool | True | Enable label caching V2 |
| `label_cache_expiry_minutes` | int | 60 | Label cache expiry time |
| `use_cache_first` | bool | False | Enable cache-first mode with background sync |

### Cache Directory Behavior

By default, the client uses platform-appropriate user cache directories:

- **Windows**: `%LOCALAPPDATA%\d365fo-client` (e.g., `C:\Users\username\AppData\Local\d365fo-client`)
- **macOS**: `~/Library/Caches/d365fo-client` (e.g., `/Users/username/Library/Caches/d365fo-client`)
- **Linux**: `~/.cache/d365fo-client` (e.g., `/home/username/.cache/d365fo-client`)

You can override this by explicitly setting `metadata_cache_dir`:

```python
from d365fo_client import FOClientConfig

# Use custom cache directory
config = FOClientConfig(
base_url="https://your-fo-environment.dynamics.com",
metadata_cache_dir="/custom/cache/path"
)

# Or get the default cache directory programmatically
from d365fo_client import get_user_cache_dir

cache_dir = get_user_cache_dir("my-app") # Platform-appropriate cache dir
config = FOClientConfig(
base_url="https://your-fo-environment.dynamics.com",
metadata_cache_dir=str(cache_dir)
)
```

## Testing

This project includes comprehensive testing at multiple levels to ensure reliability and quality.

### Unit Tests

Run standard unit tests for core functionality:

```bash
# Run all unit tests
uv run pytest

# Run with coverage
uv run pytest --cov=d365fo_client --cov-report=html

# Run specific test file
uv run pytest tests/test_client.py -v
```

### Integration Tests

The project includes a sophisticated multi-tier integration testing framework:

#### Quick Start

```bash
# Run sandbox integration tests (recommended)
.\tests\integration\integration-test-simple.ps1 test-sandbox

# Run mock server tests (no external dependencies)
.\tests\integration\integration-test-simple.ps1 test-mock

# Run with verbose output
.\tests\integration\integration-test-simple.ps1 test-sandbox -VerboseOutput
```

#### Test Levels

1. **Mock Server Tests** - Fast, isolated tests against a simulated D365 F&O API
- No external dependencies
- Complete API simulation
- Ideal for CI/CD pipelines

2. **Sandbox Tests** โญ *(Default)* - Tests against real D365 F&O test environments
- Validates authentication
- Tests real API behavior
- Requires test environment access

3. **Live Tests** - Optional tests against production environments
- Final validation
- Performance benchmarking
- Use with caution

#### Configuration

Set up integration testing with environment variables:

```bash
# Copy the template and configure
cp tests/integration/.env.template tests/integration/.env

# Edit .env file with your settings:
INTEGRATION_TEST_LEVEL=sandbox
D365FO_SANDBOX_BASE_URL=https://your-test.dynamics.com
D365FO_CLIENT_ID=your-client-id
D365FO_CLIENT_SECRET=your-client-secret
D365FO_TENANT_ID=your-tenant-id
```

#### Available Commands

```bash
# Test environment setup
.\tests\integration\integration-test-simple.ps1 setup
