bool
Signature
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:
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
​
router
MCPRouter
required
The MCPRouter instance to include
​
prefix
str
default:""
Optional prefix to add to all tool names (e.g., “math” -> “math_add”)
​
enabled
bool
default:"True"
Whether to enable this router (default True). Set to False to skip registration.
Signature
def include_router(router: MCPRouter, prefix: str = "", enabled: bool = True):
