Next.js DevTools

Inspect and debug Next.js applications via MCP server.

Quick Start

# 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

# 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

# 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

Pattern 3: Component Discovery

python3 scripts/mcp-client.py call \
  -s "npx next-devtools-mcp@latest" \
  -t list-components

Scripts

start-server.sh

For persistent server (multiple calls):

bash scripts/start-server.sh
# Server runs on default port
# Use mcp-client.py with -u flag instead of -s

On-Demand (Recommended)

For single calls, use -s flag which spawns server per-call:

python3 scripts/mcp-client.py call \
  -s "npx next-devtools-mcp@latest" \
  -t <tool-name>

Troubleshooting

Issue	Solution
Server not starting	Check `npx next-devtools-mcp@latest` works manually
No routes found	Ensure running from Next.js project root
Build info empty	Run `next build` first
