Repo hosting the Model Context Protocol Server for troubleshooting OVN-Kubernetes

概要

Repo hosting the Model Context Protocol Server for troubleshooting OVN-Kubernetes. To use the MCP server, ensure you have Go installed with a version greater than or equal to the version specified in the go.mod file. The server currently supports 2 transport modes: stdio and http. For stdio mode, the server can be run and connected to by using the following configuration in an MCP host (Cursor, Claude, etc.): For http mode, the server should be started separately: The following configuration should be used in an MCP host (Cursor, Claude, etc.) to connect to the server: For offline troubleshooting (e.g., analyzing sosreports, must-gathers), use --mode offline: Must-gather tools require the omc binary. Some must-gather tools also require the ovsdb-tool binary; if it is not available, those tools are not registered.

Operating Modes

Mode	Description
`live-cluster` (default)	Connect to a live Kubernetes cluster for real-time debugging (requires kubeconfig).
`offline`	Analyze sosreports and must-gathers without cluster access.
`dual`	Exposes tools from dual live-cluster and offline modes (requires kubeconfig for live-cluster tools).

How to connect to the MCP Server

To use the MCP server, ensure you have Go installed with a version greater than or equal to the version specified in the go.mod file.

The server currently supports 2 transport modes: stdio and http.

`--mode`	`live-cluster`	Server mode: `live-cluster`, `offline`, or `dual`.
`--transport`	`stdio`	Transport: `stdio` or `http`.
`--host`	`localhost`	Address the HTTP server binds to (`http` only). Use `0.0.0.0` in a container so clients can reach the listener.
`--port`	`8080`	Port for HTTP transport.
`--kubeconfig`	(none)	Path to kubeconfig file. Omit when using in-cluster ServiceAccount credentials (for example the pod deployment); otherwise set for `live-cluster` and `dual`.
`--pwru-image`	`docker.io/cilium/pwru:v1.0.10`	Container image for the pwru network tool (kernel packet tracing).
`--tcpdump-image`	`nicolaka/netshoot:v0.15`	Container image for the tcpdump network tool (packet capture).
`--kernel-image`	`nicolaka/netshoot:v0.15`	Container image for kernel tools (conntrack, ip, iptables, nft).
