# Governing Nodes in Agent Visualizer

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

See which nodes in your agent network are protected and which policies are applied. Open the asset
in API Manager to review more details about its policies. If a node isn’t protected, you can add a
managed Omni Gateway and create the appropriate instance to enforce policies.

## View Node Policies

1.  Look for the shield icon on nodes to see which nodes are secured by Omni Gateways.

2.  Click the node to open the details card and see the policies that are applied to the node.

3.  Click **View Policies** to view the policies for this instance in API Manager.

    Policies are listed by category on the left and applied policies are listed on the right.

## Add an Omni Gateway

Add a managed Omni Gateway to the node to enforce authentication, rate limits, and other policies at
ingress and egress, and to emit telemetry for monitoring and visualization.

1.  Click the node to open the details card.

2.  Click **Add Omni Gateway**.

3.  In API Manager, add an instance of the asset (MCP server or agent) to protect.

    For information about adding an MCP server or agent instance, see
    [Add an Omni Gateway Agent or Tool Instance](https://docs.mulesoft.com/api-manager/latest/create-instance-task-agent-tool).
