# AGENTS
|

# Project Agents.md for Kubernetes MCP Server
|
||||
|
||||
This repository contains a Go implementation of a Model Context Protocol (MCP)
|
||||
server for Kubernetes and OpenShift.
|
||||
This Agents.md file provides comprehensive guidance for AI assistants and coding agents (like Claude, Gemini, Cursor, and others) to work with this codebase.
|
||||
|
||||
## Repository layout
|
||||
This repository contains the kubernetes-mcp-server project,
|
||||
a powerful Go-based Model Context Protocol (MCP) server that provides native Kubernetes and OpenShift cluster management capabilities without external dependencies.
|
||||
This MCP server enables AI assistants (like Claude, Gemini, Cursor, and others) to interact with Kubernetes clusters using the Model Context Protocol (MCP).
|
||||
|
||||
- `cmd/kubernetes-mcp-server/` – entry point and Cobra CLI.
|
||||
- `pkg/` – libraries grouped by domain (`kubernetes`, `mcp`, `output`, …).
|
||||
## Project Structure and Repository layout
|
||||
|
||||
- Go package layout follows the standard Go conventions:
|
||||
- `cmd/kubernetes-mcp-server/` – main application entry point using Cobra CLI framework.
|
||||
- `pkg/` – libraries grouped by domain.
|
||||
- `config/` – configuration management.
|
||||
- `helm/` - Helm chart operations integration.
|
||||
- `http/` - HTTP server and authorization middleware.
|
||||
- `kubernetes/` - Kubernetes client management, authentication, and access control.
|
||||
- `mcp/` - Model Context Protocol (MCP) server implementation with tool registration and STDIO/HTTP support.
|
||||
- `output/` - output formatting and rendering.
|
||||
- `.github/` – GitHub-related configuration (Actions workflows, issue templates...).
|
||||
- `docs/` – documentation files.
|
||||
- `npm/` – Node packages that wraps the compiled binaries for distribution through npmjs.com.
|
||||
- `python/` – Python package providing a script that downloads the correct platform binary from the GitHub releases page and runs it for distribution through pypi.org.
|
||||
- `Dockerfile` - container image description file to distribute the server as a container image.
|
||||
- `Makefile` – tasks for building, formatting, linting and testing.
|
||||
- `npm/` – Node packages that wrap the compiled binary. The `kubernetes-mcp-server` package
|
||||
defines a small launcher in `bin/index.js` which resolves the platform specific
|
||||
optional dependency (`kubernetes-mcp-server-<os>-<arch>`) and executes it.
|
||||
- `python/` – Python package providing a script that downloads the correct
|
||||
platform binary from the GitHub releases page and runs it.
|
||||
|
||||
## Feature development
|
||||
|
||||
Implement new functionality in the Go sources under `cmd/` and `pkg/`.
|
||||
The JavaScript and Python directories only wrap the compiled binary for
|
||||
distribution (npm and PyPI). Most changes will not require touching them
|
||||
unless the version or packaging needs to be updated.

```
|
||||
|
||||
The server is typically run locally and connects to the cluster using the same
|
||||
configuration loading rules as `kubectl`. When started with `npx` or `uvx` it
|
||||
downloads and executes a platform specific binary. The running process then
|
||||
reads the kubeconfig resolved from the `--kubeconfig` flag, the `KUBECONFIG`
|
||||
environment variable or the default `~/.kube/config` file. If those are not
|
||||
present and the process executes inside a pod it falls back to in-cluster
|
||||
configuration. This means that `npx kubernetes-mcp-server` on a workstation will
|
||||
talk to whatever cluster your current kubeconfig points to (e.g. a local Kind
|
||||
cluster).
|
||||
To run the server locally, you can use `npx`, `uvx` or execute the binary directly:
|
||||
|
||||
```bash
|
||||
# Using npx (Node.js package runner)
|
||||
npx -y kubernetes-mcp-server@latest
|
||||
|
||||
# Using uvx (Python package runner)
|
||||
uvx kubernetes-mcp-server@latest
|
||||
|
||||
# Binary execution
|
||||
./kubernetes-mcp-server
|
||||
```
|
||||
|
||||
This MCP server is designed to run both locally and remotely.
|
||||
|
||||
### Local Execution
|
||||
|
||||
When running locally, the server connects to a Kubernetes or OpenShift cluster using the kubeconfig file.
|
||||
It reads the kubeconfig from the `--kubeconfig` flag, the `KUBECONFIG` environment variable, or defaults to `~/.kube/config`.
|
||||
|
||||
This means that `npx -y kubernetes-mcp-server@latest` on a workstation will talk to whatever cluster your current kubeconfig points to (e.g. a local Kind cluster).
|
||||
|
||||
### Remote Execution
|
||||
|
||||
When running remotely, the server can be deployed as a container image in a Kubernetes or OpenShift cluster.
|
||||
The server can be run as a Deployment, StatefulSet, or any other Kubernetes resource that suits your needs.
|
||||
The server will automatically use the in-cluster configuration to connect to the Kubernetes API server.
