What you can do with this MCP connector
This server connects your AI client right into the Cilium agent, letting you manage your Kubernetes networking stack using eBPF. You'll use natural language to check the system, verify daemon health, and control container connectivity. You don't gotta write complex CLI commands to audit network policies.
Checking the Daemon Status
Run get_healthz to get the real-time operational status of the Cilium daemon. It tells you if the daemon is connected to Kubernetes and Hubble. You can also use get_config to pull the current operational parameters and settings of the Cilium daemon.
Seeing Your Cluster Nodes
get_cluster_nodes retrieves a list of every node visible to the Cilium agent. This lets you confirm which nodes are active and what their IP addresses are.
Managing Network Endpoints
Your AI client can use create_endpoint to build a new networking endpoint for a container. It can also use get_endpoint to pull the details for a specific network endpoint ID, or just get_endpoint to get the details for a specific network endpoint ID.
Modifying Settings
You can update the Cilium daemon settings and datapath modes programmatically using patch_config. This lets you change specific settings and parameters within the daemon configuration.
Here’s the rundown of what you can do:
- Get Daemon Health: You run
get_healthzto report the real-time operational status of the Cilium daemon, including connectivity to Kubernetes and Hubble. - List Cluster Nodes: You use
get_cluster_nodesto retrieve a list of all nodes visible to the Cilium agent, confirming their status and IP addresses. - Manage Network Endpoints: You can
create_endpoint,get_endpoint, and get endpoint details to control container connectivity and network policies. - View Daemon Configuration: You retrieve current operational parameters and settings of the Cilium daemon using
get_config. - Modify Configuration: You update the Cilium daemon settings and datapath modes programmatically via
patch_config.
How Cilium (eBPF Networking) MCP Works
- 1 Subscribe to the server and input your specific Cilium API URL.
- 2 Ask your agent to perform an action (e.g., 'Check Cilium health').
- 3 The server executes the corresponding tool (e.g.,
get_healthz) and returns the result to your agent.
The bottom line is, you talk to your AI client, and the server translates that into API calls to manage your network stack.
Who Is Cilium (eBPF Networking) MCP For?
The ops engineer who gets tired of jumping between Grafana, kubectl get nodes, and complex API calls just to verify a network change. This is for anyone who needs deep visibility into Kubernetes networking without writing a single YAML file or remembering a specific CLI flag.
Troubleshoots connectivity issues by querying daemon configuration (get_config) or checking endpoint labels to verify network policy enforcement.
Quickly audits the entire cluster health and node status using get_cluster_nodes to validate deployment readiness.
Manages container connectivity by listing and creating specific networking endpoints using create_endpoint and get_endpoint.
What Changes When You Connect
- Get instant cluster visibility. Instead of running
kubectl get nodesand manually cross-referencing IP ranges, useget_cluster_nodesto get a clean, structured list of every node known to the agent. - Verify network policy enforcement instantly. You can check endpoint labels and states using
get_endpointto confirm if a container has the expected connectivity before deployment. - Fix config issues without SSHing. Use
get_configto read current daemon settings. Then, usepatch_configto update a specific parameter without logging into a machine. - Smarter debugging. Check the full operational status with
get_healthz. It confirms the daemon, container runtime, and datastore are all active and connected. - Manage connectivity from chat. Creating or inspecting endpoints—core network tasks—is handled by
create_endpointandget_endpoint. It’s all natural language.
Real-World Use Cases
Validating a New Service Mesh Deployment
The SRE team needs to confirm that a new service is correctly connected. They ask their agent, 'What's the status of the endpoint for app-billing?' The agent calls get_endpoint and reports if the endpoint is 'ready' and what IP it's assigned. They know the service is ready to go.
Troubleshooting Network Downtime
A service fails suddenly. The engineer asks the agent to run get_healthz and get_config. The agent reports the daemon's health and the current datapath mode, allowing the engineer to immediately spot if the issue is configuration-related.
Onboarding a New Cluster Node
The platform team deploys a new node. They ask the agent to run get_cluster_nodes. The agent confirms the node's existence and IP address, validating the cluster is fully synchronized before any workloads are deployed.
Adjusting Network Parameters Mid-Deployment
The DevOps team realizes a default setting needs tweaking. Instead of manually editing files and restarting services, they ask the agent to run get_config to see the current value, then patch_config to update it.
The Tradeoffs
Manual CLI Drilling
The engineer logs into a jump box, runs cilium status, then runs cilium get nodes, and finally checks a separate dashboard for the endpoint status. This is slow, tedious, and easy to miss a step.
→
Ask your agent to run a sequence: first get_cluster_nodes for an overview, then get_healthz to confirm basic uptime. If needed, finish by calling get_endpoint for specific details. It's faster and all in one place.
Assuming Configuration State
The engineer remembers a setting changed last week but doesn't know the current value, so they just run patch_config with a guess, potentially breaking the service.
→
Always check first. Run get_config to see the current, live value. Then, if you need to change it, use patch_config with the validated parameters.
Ignoring Interdependencies
The engineer tries to create an endpoint (create_endpoint) without verifying the cluster node is actually healthy or visible. The endpoint fails because the underlying network state is broken.
→
Start with a full check. Always run get_healthz first. This confirms the foundation is solid before you attempt any state changes like create_endpoint or patch_config.
When It Fits, When It Doesn't
Use this if you need deep, real-time visibility into the internal workings of your Kubernetes network plane. You need to audit node status, check daemon health, or make granular changes to endpoints without touching a terminal. It's perfect for SREs and platform teams who need to validate state before writing code.
Don't use this if your only goal is to check basic cluster resource consumption (like CPU usage on all pods). For that, stick to standard cloud monitoring tools. If you only need a simple list of running pods, kubectl get pods is still faster. This server is for the networking layer itself.

Available Capabilities
Checking the status of a node shouldn't take three different commands.
Today, checking cluster status means running `kubectl get nodes` to see node health, then running `cilium status` to check the agent, and maybe checking a separate dashboard to verify if the specific endpoint exists. It's a sequence of commands and dashboards that makes debugging slow and painful.
With the Cilium MCP Server, you ask your agent, 'What's the status of the cluster?' The agent runs `get_cluster_nodes` and `get_healthz`, combining the node list and the daemon health into one structured answer. You get a single, actionable report.
Cilium (eBPF Networking) MCP Server: Control network endpoints and daemon settings
Before, modifying a networking setting meant manually editing configuration files, committing the change, and restarting the service—a high-risk, multi-step process. You had to remember which file controlled which parameter.
Now, you simply tell your agent, 'Change the datapath mode to X.' The agent uses `get_config` to validate the current setting, then runs `patch_config` to apply the change safely. It's precise, auditable, and happens in chat.
