Quickstart

Get your MCP server secured with authorization in under 5 minutes.

Step 1: Install the Middleware

pip install eunomia-mcp

Step 2: Add Middleware to Your Server

server.py

from fastmcp import FastMCP
from eunomia_mcp import create_eunomia_middleware

# Create your FastMCP server
mcp = FastMCP("Secure MCP Server 🔒")

@mcp.tool()
def add(a: int, b: int) -> int:
    """Add two numbers"""
    return a + b

# Add middleware to your server
middleware = create_eunomia_middleware(policy_file="mcp_policies.json")
mcp.add_middleware(middleware)

if __name__ == "__main__":
    mcp.run()

Step 3: Use Your Server

You can now run your MCP server normally:

python server.py

Your server now has authorization middleware! By default, all requests will be denied until you configure policies.
