What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
claude mcp add gcs -- npx -y gcs-google-mcp-server

"mcpServers": {
"gcs": {
"args": [

This one needs environment variables set before it will start:
GCS_PROJECT_ID (Google Cloud project ID.), GCS_SERVICE_ACCOUNT_KEY_FILE (Path to service account key JSON file.), GCS_SERVICE_ACCOUNT_KEY_JSON (Service account key JSON contents (inline).), GCS_BUCKET (Constrain all operations to a single bucket (hides bucket-level tools).), GCS_ENABLED_TOOLGROUPS (Comma-separated tool groups to enable (readonly, readwrite, delete).), GCS_ENABLED_TOOLS (Comma-separated list of specific tools to enable (overrides groups).), GCS_DISABLED_TOOLS (Comma-separated list of specific tools to disable.), SKIP_HEALTH_CHECKS (Skip health checks on startup.).
