MCP Servers & AI Agents SDK

SDK for integrating Model Context Protocol (MCP) servers and AI agents with AuthSec authentication and authorization.

How to Integrate Authentication into Your MCP Server / SDK Agent?

Learn how to integrate your AI agent by securely authenticating your MCP server or agent using our authentication API.

Python
TypeScript

Step 1: Install AuthSec SDK

pip install git+https://github.com/authsec-ai/sdk-authsec.git

Step 2: Create Your Secure MCP Server (server.py)

from authsec_sdk import protected_by_AuthSec, run_mcp_server_with_oauth

# Tool 1: Accessible to all authenticated users
@protected_by_AuthSec("hello")
async def hello(arguments: dict) -> list:
    return [{
        "type": "text",
        "text": f"Hello, {arguments['_user_info']['email']}!"
    }]

# Start the server
if __name__ == "__main__":
    run_mcp_server_with_oauth(
        client_id="your-client-id-here",
        app_name="My Secure MCP Server"
    )

Step 3: Run Your Server

python server.py

How Do You Do Autonomous Agent (Machine to Machine) Authorization?

Learn how to deploy SPIRE agents on Kubernetes, Docker, and VM environments for secure machine-to-machine communication.

Kubernetes
Docker
VM

Method 1: Helm Chart (Recommended)
Method 2: kubectl (Manual Deployment)

Step 1: Add Helm Repository

# Add AuthSec Helm repo
helm repo add authsec https://charts.authsec.ai
helm repo update

Step 2: Create values.yaml

cat > icp-agent-values.yaml <<EOF
# ICP Agent Configuration

EOF

Step 3: Install Agent

# Install in default namespace
helm install icp-agent authsec/icp-agent \
  -f icp-agent-values.yaml \
  --namespace default \
  --create-namespace

# Wait for DaemonSet to be ready
kubectl rollout status daemonset/icp-agent -n default

Step 4: Verify Installation

# Check DaemonSet
kubectl get daemonset -n default

# Check pods (should be 1 per node)
kubectl get pods -n default -l app=icp-agent -o wide

# Check logs
kubectl logs -n default -l app=icp-agent --tail=50

# Check health
kubectl exec -n default -l app=icp-agent -- curl http://localhost:8080/healthz

Step 1: Create Namespace

kubectl create namespace default

Step 2: Deploy ConfigMap

kubectl apply -f - <<EOF

Start the agent
Enable auto-start on boot

Step 1: Install Dependencies

Ubuntu/Debian:

sudo apt-get update
sudo apt-get install -y python3 python3-pip git systemd

RHEL/CentOS:

sudo yum install -y python3 python3-pip git systemd

Step 2: Download ICP Agent

# Create installation directory
sudo mkdir -p /opt/icp-agent
cd /opt/icp-agent

# Clone repository
sudo git clone https://github.com/your-org/icp-agent.git .

# Install Python dependencies
sudo pip3 install -r requirements.txt

sudo mkdir -p /var/log/icp-agent
sudo mkdir -p /run/spire/sockets

# Set permissions
sudo chmod 755 /run/spire/sockets
sudo chmod 700 /var/lib/icp-agent

Step 6: Start Agent

# Reload systemd
sudo systemctl daemon-reload

# Start agent
sudo systemctl start icp-agent

# Enable auto-start on boot
sudo systemctl enable icp-agent

# Check status
sudo systemctl status icp-agent

Verification

# Check agent is running
sudo systemctl status icp-agent

# Check logs
sudo journalctl -u icp-agent -f

# Check socket exists
ls -l /run/spire/sockets/agent.sock

# Test health endpoint
curl http://localhost:8080/healthz

Expected output:
