Nextscan
Overview
nextscan
MCP server that scans Next.js projects and returns a compact summary. One tool call → full project overview.
What it does
| Without nextscan | With nextscan |
|---|---|
| Manual file-by-file exploration | Single scan call |
| Multiple tool calls to understand routes | Compact route tree with flags |
| Missing security issues | Hardcoded secrets + env leak detection |
| Unknown API coverage | Auth + validation status per endpoint |
| Schema guesswork | Prisma/Drizzle relation mapping |
Quick Install
# Clone and build
cd nextscan
npm install
npm run build
# Add to Claude Code
claude mcp add nextscan -- node /path/to/nextscan/dist/index.js
Tool: scan
| Parameter | Type | Required | Description |
|---|---|---|---|
