# Cilium (eBPF Networking) MCP for AI Agents AI Agent Connect

> Cilium (eBPF Networking) MCP lets you manage Kubernetes networking and eBPF health via natural language. It gives your AI client the ability to audit cluster nodes, update daemon configurations, and inspect networking endpoints without you having to remember complex CLI flags or navigate nested directories.

## Description

This Connector connects your AI client to your Cilium agent. It gives you a way to talk to your Kubernetes networking stack without memorizing every CLI flag or digging through nested directories. You can check if your daemon is healthy, see which nodes are active, and tweak your configs on the fly. It's built for people who need to move fast and want to stay in their flow state. Instead of running multiple commands to verify a node's status or checking if a configuration change actually stuck, you just ask your agent. You can audit your cluster nodes, create new endpoints, and inspect specific container connectivity in seconds. It handles the heavy lifting of interacting with the eBPF layer so you don't have to. You can quickly list nodes to see what's reachable, patch daemon settings to fix routing issues, or pull endpoint details to verify security labels. It's all about getting the answers you need from your networking stack as quickly as you can think of the question. You'll find this and thousands of other tools in the Vinkius catalog, making it easy to plug into your existing workflow without extra overhead. This is how you manage complex infrastructure without the typical friction of manual terminal navigation.

## Tools

### get_endpoint
Get specific details for a networking endpoint by its ID. It returns key info like assigned IPs and labels.

### get_healthz
Check the current health status of your Cilium daemon. This is your first step for diagnosing any connectivity issues in the cluster.

### get_cluster_nodes
Retrieve a list of all nodes known to your local Cilium agent. It shows you exactly what the networking layer sees.

### patch_config
Update your daemon configuration settings directly. This allows you to change behavior without having to manually edit files or restart services.

### create_endpoint
Add new networking endpoints to your cluster. You can use this to manage how your containers connect and communicate.

### get_config
Read the current configuration of your Cilium daemon. Use this to verify that your latest changes actually took effect.

## Prompt Examples

**Prompt:** 
```
Check the health status of the Cilium daemon.
```

**Response:** 
```
I've checked the Cilium health status. The daemon is healthy, with active connectivity to Kubernetes and Hubble. Container runtime status is also green.
```

**Prompt:** 
```
List all cluster nodes known to the agent.
```

**Response:** 
```
I've retrieved the cluster nodes. I found 3 nodes: 'node-1' (10.0.0.1), 'node-2' (10.0.0.2), and 'node-3' (10.0.0.3). All are currently reachable.
```

**Prompt:** 
```
Get the details for endpoint ID cilium-local:123.
```

**Response:** 
```
Inspecting endpoint 'cilium-local:123'... It is in 'ready' state, assigned IP 10.244.1.5, and carries labels like 'app=frontend'.
```

## Capabilities

### Check daemon health
Get real-time status of the Cilium daemon to ensure your networking stack is active.

### List cluster nodes
Retrieve a full list of all nodes currently known to your local Cilium agent.

### Update daemon settings
Modify your daemon configuration options on the fly without manual file editing.

### Add new endpoints
Create new networking endpoints to manage container connectivity and security.

### View current configs
Read the current configuration of your Cilium daemon to verify that changes applied.

### Lookup endpoint details
Get specific information like IPs and labels for any networking endpoint by its ID.

## Use Cases

### Diagnosing a node connectivity failure
An SRE notices a node is unreachable and asks the agent to check the Cilium daemon health and list all known nodes to find the discrepancy.

### Verifying security policy labels
A security engineer asks for the labels and IP of a specific endpoint ID to ensure it matches the required network policy.

### Quick configuration updates
A DevOps engineer needs to change a daemon setting and uses the agent to patch the config and then verify it with the config tool.

### Rapid endpoint creation
A platform engineer uses the agent to create a new networking endpoint as part of a new service rollout to ensure container connectivity.

## Benefits

- Get instant daemon status updates with `get_healthz` to identify connectivity issues before they escalate.
- Audit your entire cluster node list using `get_cluster_nodes` to see exactly what the networking layer sees.
- Modify daemon settings on the fly with `patch_config` to fix routing problems without restarting services.
- Manage container connectivity by quickly adding new endpoints with `create_endpoint`.
- Verify that your latest changes actually took effect by reading the current state with `get_config`.
- Inspect specific endpoint details like IPs and labels using `get_endpoint` for granular security checks.

## How It Works

The bottom line is you get to manage complex eBPF networking with plain English instead of jumping through multiple CLI tools.

1. Subscribe to the Connector
2. Enter your Cilium API URL
3. Ask your agent questions about your cluster

## Frequently Asked Questions

**What does the Cilium (eBPF Networking) MCP do?**
It connects your AI client to your Cilium agent, allowing you to manage Kubernetes networking, check daemon health, and audit cluster nodes using natural language.

**Can I use Cilium (eBPF Networking) MCP to check node health?**
Yes. You can ask your agent to check the health of the Cilium daemon or list all nodes known to the agent to see what's reachable in your cluster.

**How do I manage Kubernetes network policies with this?**
You can use the Connector to inspect specific endpoint details, including labels and IPs, which helps you verify and manage your network security policies.

**Is Cilium (eBPF Networking) MCP good for SREs?**
It's a great tool for SREs because it simplifies troubleshooting. You can quickly query daemon configurations and health metrics without memorizing complex CLI commands.

**Can I update my Cilium config using this?**
Yes, you can use the Connector to patch daemon configurations on the fly. This lets you change settings based on your instructions without manually editing files.

**Does Cilium (eBPF Networking) MCP work with Cursor?**
Yes, it works with Cursor and any other MCP-compatible client like Claude or Windsurf once you've connected your Cilium API URL.

**Can I check if the Cilium daemon is connected to Kubernetes and Hubble?**
Yes. Use the `get_healthz` tool. It returns the status of all critical components including Kubernetes connectivity, Hubble, and the container runtime.

**How do I retrieve the configuration of a specific network endpoint?**
You can use the `get_endpoint` tool by providing the endpoint ID (e.g., 'cilium-local:123'). It will return addressing, labels, and current state metadata.

**Is it possible to update the Cilium daemon configuration via this agent?**
Yes, the `patch_config` tool allows you to update daemon specification options, which triggers a regeneration of datapath components.
