# Mineralis MCP bridge installer for PowerShell. Fetches the bridge from the service that
# serves this script, installs its one dependency, and registers it with your MCP client.
#
# Usage:  irm https://mineralis.digiearth.com.au/mineralis-mcp/install.ps1 | iex
#         $env:MINERALIS_API_TOKEN = 'mrl_...'; irm https://mineralis.digiearth.com.au/mineralis-mcp/install.ps1 | iex
#
# It creates one directory, runs npm install inside it, and - if the claude CLI is on your
# PATH - registers the server with it. Your API token is never written to a file by this
# script.
#
# No execution policy change is needed. Nothing here loads a .ps1 file from disk: npm and
# claude are called through their .cmd or .exe shims, because a Restricted or AllSigned
# policy refuses the .ps1 shim PowerShell would otherwise pick first.

# The first shim for a command that is not itself a PowerShell script, so no execution
# policy can refuse it. Get-Command on a bare name would hand back npm.ps1 or claude.ps1.
