Next.js development tooling via MCP. Inspect routes, components, build info, and debug Next.js apps. Use when working on Next.js applications, debugging routing, or inspecting app structure. NOT for general React or non-Next.js projects.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Next.js DevTools
Inspect and debug Next.js applications via MCP server.
## Quick Start
```bash
# Start server (spawns on-demand)
bash scripts/start-server.sh
# Or use directly via mcp-client
python3 scripts/mcp-client.py call \
-s "npx next-devtools-mcp@latest" \
-t list-routes
```
## Available Tools
| Tool | Description |
|------|-------------|
| `list-routes` | Get all app routes |
| `get-route-info` | Details for specific route |
| `list-components` | React components in app |
| `get-build-info` | Build configuration |
| `get-config` | next.config.js settings |
## Workflow Patterns
### Pattern 1: Route Inspection
```bash
# List all routes
python3 scripts/mcp-client.py call \
-s "npx next-devtools-mcp@latest" \
-t list-routes
# Get specific route details
python3 scripts/mcp-client.py call \
-s "npx next-devtools-mcp@latest" \
-t get-route-info \
-p '{"route": "/api/auth"}'
```
### Pattern 2: Debug Build Issues
```bash
# Check build config
python3 scripts/mcp-client.py call \
-s "npx next-devtools-mcp@latest" \
-t get-build-info
# Check next.config.js
python3 scripts/mcp-client.py call \
-s "npx next-devtools-mcp@latest" \
-t get-config
```

How to install
mdr add mjunaidca/mjs-agent-skills/nextjs-devtools@sha256:278acbb34f61feebThe line at the top of this page pins the label git:20251222.62955e5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
