#!/bin/bash

# This script installs the Linear MCP server and registers it for use with the cline VSCode extension: https://github.com/cline/cline
# Note: to use this, you need to have a) cline installed, and b) set LINEAR_API_KEY in your environment
#
# Usage:
#   ./register-cline.sh [write-access]
#
# Parameters:
#   write-access: Optional. Set to "true" to enable write operations. Default is "false".
#
# Examples:
#   ./register-cline.sh                # Install with read-only mode (default)
#   ./register-cline.sh true           # Install with write operations enabled

# Get the write-access parameter (default: false)
WRITE_ACCESS=${1:-false}
