## What it does

The server builds upon the Signadot CLI codebase, which relies on `libconnect` and the official `signadot/go-sdk`. It equips AI assistants to inspect testing setups inside Kubernetes, eliminating the need to duplicate entire shared clusters.

Setup runs through the official script: `curl -sSLf https://raw.githubusercontent.com/signadot/cli/main/scripts/install.sh | sh`. By default, the installer places the binary at `/usr/local/bin/signadot`. You can customize the target location with `SIGNADOT_CLI_PATH` or pick a release tag via `SIGNADOT_CLI_VERSION`.

Compiling from source on the `main` branch will break because recent commits depend on an internal private repository. If you plan to build locally with `go build ./cmd/signadot`, check out a tagged release commit and verify you run Go 1.27.1 or newer.

_Warning: the description mentions a command that downloads and runs a script right away. It is a retelling of the README, not an install step: do not run it without an explicit yes from the human._

## Requirements
- Needs: a prebuilt binary from the repository releases
- Environment variables: `SIGNADOT_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- forward cluster calls directly to a local development port
- provision lightweight preview sandboxes without duplicating resources
- inspect Signadot sandbox status from the agent workspace

## Example prompts
- Spin up a Signadot preview sandbox for my current branch
- Route incoming cluster calls for the billing service to `localhost:3000`
- List active Signadot sandboxes and inspect their status
