Main MCP Server class with integrated inspector and development tools.
```python theme={null}
from mcp_use.server.server import MCPServer
```
### `method` **init**
Initialize an MCP server.
**Parameters**
> Server name for identification
> Server version string
> Instructions for the AI model using this server
> Optional list of icons for the server implementation
> Parameter value
> List of middleware to apply to requests
> Enable debug mode (adds /docs, /inspector, /openmcp.json endpoints)
> Path for MCP endpoint (default: "/mcp")
> Path for documentation endpoint (default: "/docs")
> Base path prefix for the inspector UI; final route is `/inspector`.
> Path for OpenMCP metadata (default: "/openmcp.json")
> Show inspector-related logs
> Pretty print JSON-RPC messages in logs
> Only show MCP protocol logs, suppress HTTP access logs (default: False)
> Default host for server binding (default: "0.0.0.0"). Can be overridden in run().
> Default port for server binding (default: 8000). Can be overridden in run().
> Enable DNS rebinding protection by validating Host/Origin

### `property` debug
Whether debug mode is enabled.
**Returns**

def debug():
```
### `method` include\_router
Include a router's tools, resources, and prompts into this server.
Similar to FastAPI's include\_router, this allows you to organize your
MCP server into multiple files/modules.
Example:
```python theme={null}
from mcp_use.server import MCPServer, MCPRouter
# In routes/math.py
router = MCPRouter()
@router.tool()
def add(a: int, b: int) -> int:
return a + b
# In main.py
server = MCPServer(name="my-server")
server.include_router(router, prefix="math") # Tool becomes "math_add"
server.include_router(other_router, enabled=False) # Skip this router
```
**Parameters**
> The MCPRouter instance to include
> Optional prefix to add to all tool names (e.g., "math" -> "math\_add")
> Whether to enable this router (default True). Set to False to skip registration.
**Signature**
```python wrap theme={null}
def include_router(router: MCPRouter, prefix: str = "", enabled: bool = True):
```
### `method` notify\_resource\_updated
Notify all subscribed sessions that a resource has been updated.
Broadcasts a `notifications/resources/updated` message to every session
that called `resources/subscribe` for this URI.
Can be called from within a tool handler or from any async context.
**Parameters**
> The URI of the resource that was updated.
**Signature**
```python wrap theme={null}
def notify_resource_updated(uri: str):
