GKE MCP Server

Google Cloud's MCP server and Gemini CLI extension for GKE clusters: resources, logs, deploys, costs and upgrade risks

MCP serverHigh risk

googlecloudplatform/gke-mcpAuthor: Google Cloud

Install

gemini extensions install https://github.com/GoogleCloudPlatform/gke-mcp.git

This is third-party code. Review the repository files before installing.

What it does

The server lets the agent work with Google Kubernetes Engine. The agent lists, creates and updates clusters and node pools, reads Kubernetes resources, events and logs, applies manifests and queries Cloud Logging. Bundled prompts help analyze GKE costs and assess control plane upgrade risks. Deleting clusters and node pools is available only when explicitly enabled.

Who it is for. For DevOps engineers and developers who run clusters on GKE.

Good fit when

  • You need to find why a pod crashes using logs and events
  • You want to assess risks before a cluster upgrade
  • You need to see where GKE spending goes

Not a fit when

  • Your clusters are not on Google Cloud
  • You need a tool with production guarantees

Example request

Build an upgrade risk report for prod-cluster to the next minor version

Limitations

The authors call it experimental and not for production; it is not an officially supported Google product. Requires access to a Google Cloud project. Manifest generation with documentation needs a Developer Knowledge API key. Google Cloud does not onboard new customers from Russia.

How to disable. Remove the extension with gemini extensions uninstall or delete the gke-mcp block from the client's MCP config.

README in short

The README offers three install paths: a Gemini CLI extension, a script for Linux and macOS, and go install. Other clients have separate guides in the docs folder. It lists tools, prompts for costs and upgrades, and bundled context on known GKE issues. It covers stdio and Streamable HTTP transports. Apache 2.0 licensed.
