Next.js MCP Server

A utility tool that analyzes your Next.js application routes and provides detailed information about them.

Demo

Router analysis demo

Overview

get-routers-infoThe Router Analyzer scans your Next.js app directory structure and extracts information about all API routes, including:
- API paths
- HTTP methods (GET, POST, PUT, DELETE, etc.)
- Request parameters
- Status codes
- Request and response schemas

This is particularly useful for documentation, testing, or integrating with API management tools.

Installation

npm install next-mcp-server

Or if you're using pnpm:

pnpm add next-mcp-server

Usage

Command Line

You can run the mcp server directly:

npm run build
node dist/index.js

Docker

docker build -t mcp/next -f Dockerfile .
docker run mcp/next -d

Output

The tool generates detailed information about each route:

[
  {
    "filePath": "/path/to/your/app/api/test/route.ts",
    "implementationPath": "/path/to/your/app/api/test/route.ts",
    "apiPath": "/api/test",
    "handlers": [
      {
        "method": "GET",
        "path": "/api/test",
        "functionSignature": "export async function GET(request: Request)",
        "description": "Get test data",
        "parameters": [],
        "statusCodes": [200]
      },
      {
        "method": "POST",
        "path": "/api/test",
        "functionSignature": "export async function POST(request: Request)",
        "description": "Create test data",
        "parameters": [],
        "requestBodySchema": "{ name: string }",
        "statusCodes": [201, 400]
      }
    ]
  }
]
