@nexlayer/mcp-install

One command to install the Nexlayer MCP server for all your AI coding tools.

Usage

npx @nexlayer/mcp-install

Or with flags:

npx @nexlayer/mcp-install --project   # Install for current project only
npx @nexlayer/mcp-install --restore   # Restore configs from backup (undo install)
npx @nexlayer/mcp-install --dev       # Use local dev servers
npx @nexlayer/mcp-install --help      # Show help

Supported AI Tools

The installer auto-detects which tools are installed by checking their config directories:

| Tool | Config Location | |---|---| | Claude Code | ~/.claude/ | | Cursor | ~/.cursor/ | | VS Code | ~/Library/Application Support/Code/User/ (macOS) | | Windsurf | ~/.codeium/windsurf/ | | Antigravity | ~/Library/Application Support/Antigravity/User/ (macOS) | | Zed | ~/.config/zed/ | | Amazon Q | ~/.aws/amazonq/ |

Cross-platform support: macOS, Windows, and Linux paths are all handled.

How It Works

1. Detect — Scans for installed AI coding tools
2. Authenticate — Opens browser for sign in (if auth server is available)
3. Configure — Writes MCP server config to each tool's config file

If the auth server is unavailable, the installer skips authentication and you can authenticate from within your coding tool later.

Config Formats

Different tools use different config formats:

• Claude Code / Cursor / Windsurf / Antigravity: mcpServers in JSON config
• VS Code: mcp.servers in mcp.json
• Zed: context_servers in settings.json
• Amazon Q: mcpServers with commandLine format
