MCP Setup

For local configuration with stdio transport:

{
  "mcpServers": {
    "reviewwebsite": {
      "command": "node",
      "args": ["/path/to/reviewwebsite-mcp-server/dist/index.js"],
      "transportType": "stdio"
    }
  }
}

For remote HTTP configuration:

{
  "mcpServers": {
    "reviewwebsite": {
      "type": "http",
      "url": "http://localhost:8080/mcp"
    }
  }
}

Environment Variables for HTTP Transport:

You can configure the HTTP server using these environment variables:

MCP_HTTP_HOST: The host to bind to (default: 127.0.0.1)
MCP_HTTP_PORT: The port to listen on (default: 8080)
MCP_HTTP_PATH: The endpoint path (default: /mcp)

Source Code Overview

What is MCP?

Model Context Protocol (MCP) is an open standard that allows AI systems to securely and contextually connect with external tools and data sources.

This boilerplate implements the MCP specification with a clean, layered architecture that can be extended to build custom MCP servers for any API or data source.

Why Use This Boilerplate?

Production-Ready Architecture: Follows the same pattern used in published MCP servers, with clear separation between CLI, tools, controllers, and services.
Type Safety: Built with TypeScript for improved developer experience, code quality, and maintainability.
Working Example: Includes a fully implemented IP lookup tool demonstrating the complete pattern from CLI to API integration.
Testing Framework: Comes with testing infrastructure for both unit and CLI integration tests, including coverage reporting.
Development Tooling: Includes ESLint, Prettier, TypeScript, and other quality tools preconfigured for MCP server development.

Getting Started

Prerequisites

Node.js (>=18.x): Download
Git: For version control

Step 1: Clone and Install

# Clone the repository
git clone https://github.com/mrgoonie/reviewwebsite-mcp-server.git
cd reviewwebsite-mcp-server

# Install dependencies
npm install

Step 2: Run Development Server

Start the server in development mode with stdio transport (default):

npm run dev:server

Or with the Streamable HTTP transport:

npm run dev:server:http

This starts the MCP server with hot-reloading and enables the MCP Inspector at http://localhost:5173.

⚙️ Proxy server listening on port 6277 🔍 MCP Inspector is up and running at http://127.0.0.1:6274

When using HTTP transport, the server will be available at http://127.0.0.1:8080/mcp by default.

Step 3: Test the ReviewWebsite API Tools

Use the ReviewWebsite API tools via CLI:

# Get available AI models
npm run dev:cli -- get-ai-models --api-key "your-api-key"

# Create a review
npm run dev:cli -- create-review --url "https://example.com" --instructions "Review this website" --api-key "your-api-key"

# Convert URL to Markdown
npm run dev:cli -- convert-to-markdown --url "https://example.com" --model "gpt-4o" --api-key "your-api-key"

Architecture

This boilerplate follows a clean, layered architecture pattern that separates concerns and promotes maintainability.

Layers and Responsibilities

CLI Layer (`src/cli/*.cli.ts`)

Purpose: Define command-line interfaces that parse arguments and call controllers

Testing: CLI integration tests in <feature>.cli.test.ts

Tools Layer (`src/tools/*.tool.ts`)

Purpose: Define MCP tools with schemas and descriptions for AI assistants
Naming: Files should be named <feature>.tool.ts with types in <feature>.types.ts
Pattern: Each tool should use zod for argument validation

Controllers Layer (`src/controllers/*.controller.ts`)

Purpose: Implement business logic, handle errors, and format responses
Naming: Files should be named <feature>.controller.ts
Pattern: Should return standardized ControllerResponse objects

Services Layer (`src/services/*.service.ts`)

Purpose: Interact with external APIs or data sources
Naming: Files should be named <feature>.service.ts
Pattern: Pure API interactions with minimal logic

Utils Layer (`src/utils/*.util.ts`)

Purpose: Provide shared functionality across the application
Key Utils:
- logger.util.ts: Structured logging
- error.util.ts: Error handling and standardization

Building Custom Tools

Follow these steps to add your own tools to the server:

1. Define Service Layer

Create a new service in src/services/ to interact with your external API:

// src/services/example.service.ts
import { Logger } from '../utils/logger.util.js';

const logger = Logger.forContext('services/example.service.ts');

export async function getData(param: string): Promise<any> {
	logger.debug('Getting data', { param });
	// API interaction code here
	return { result: 'example data' };
}

2. Create Controller

Add a controller in src/controllers/ to handle business logic:

// src/controllers/example.controller.ts
import { Logger } from '../utils/logger.util.js';
import * as exampleService from '../services/example.service.js';
import { formatMarkdown } from '../utils/formatter.util.js';
import { handleControllerError } from '../utils/error-handler.util.js';
import { ControllerResponse } from '../types/common.types.js';

const logger = Logger.forContext('controllers/example.controller.ts');

export interface GetDataOptions {
	param?: string;
}

export async function getData(
	options: GetDataOptions = {},
): Promise<ControllerResponse> {
	try {
		logger.debug('Getting data with options', options);

		const data = await exampleService.getData(options.param || 'default');

		const content = formatMarkdown(data);

		return { content };
	} catch (error) {
		throw handleControllerError(error, {
			entityType: 'ExampleData',
			operation: 'getData',
			source: 'controllers/example.controller.ts',
		});
	}
}

3. Implement MCP Tool

Create a tool definition in src/tools/:

// src/tools/example.tool.ts
import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js';
import { z } from 'zod';
import { Logger } from '../utils/logger.util.js';
import { formatErrorForMcpTool } from '../utils/error.util.js';
import * as exampleController from '../controllers/example.controller.js';

const logger = Logger.forContext('tools/example.tool.ts');

const GetDataArgs = z.object({
	param: z.string().optional().describe('Optional parameter'),
});

type GetDataArgsType = z.infer<typeof GetDataArgs>;

async function handleGetData(args: GetDataArgsType) {
	try {
		logger.debug('Tool get_data called', args);

		const result = await exampleController.getData({
			param: args.param,
		});

		return {
			content: [{ type: 'text' as const, text: result.content }],
		};
	} catch (error) {
		logger.error('Tool get_data failed', error);
		return formatErrorForMcpTool(error);
	}
}

export function register(server: McpServer) {
	server.tool(
		'get_data',
		`Gets data from the example API, optionally using \`param\`.
Use this to fetch example data. Returns formatted data as Markdown.`,
		GetDataArgs.shape,
		handleGetData,
	);
}

4. Add CLI Support

Create a CLI command in src/cli/:

// src/cli/example.cli.ts
import { program } from 'commander';
import { Logger } from '../utils/logger.util.js';
import * as exampleController from '../controllers/example.controller.js';
import { handleCliError } from '../utils/error-handler.util.js';

const logger = Logger.forContext('cli/example.cli.ts');

program
	.command('get-data')
	.description('Get example data')
	.option('--param <value>', 'Optional parameter')
	.action(async (options) => {
		try {
			logger.debug('CLI get-data called', options);

			const result = await exampleController.getData({
				param: options.param,
			});

			console.log(result.content);
		} catch (error) {
			handleCliError(error);
		}
	});

5. Register Components

Update the entry points to register your new components:

// In src/cli/index.ts
import '../cli/example.cli.js';

// In src/index.ts (for the tool)
import exampleTool from './tools/example.tool.js';
// Then in registerTools function:
exampleTool.register(server);

Debugging Tools

MCP Inspector

Access the visual MCP Inspector to test your tools and view request/response details:

Run npm run dev:server
Open http://localhost:5173 in your browser
Test your tools and view logs directly in the UI

Server Logs

Enable debug logs for development:

# Set environment variable
DEBUG=true npm run dev:server

# Or configure in ~/.mcp/configs.json

Publishing Your MCP Server

When ready to publish your custom MCP server:

Update package.json with your details
Update README.md with your tool documentation
Build the project: npm run build
Test the production build: npm run start:server
Publish to npm: npm publish

License

MIT License

{
	"reviewwebsite": {
		"environments": {
			"DEBUG": "true",
			"REVIEWWEBSITE_API_KEY": "your-api-key-here"
		}
	}
}

Note: For backward compatibility, the server will also recognize configurations under the full package name (reviewwebsite-mcp-server) or the unscoped package name (reviewwebsite-mcp-server) if the reviewwebsite key is not found. However, using the short reviewwebsite key is recommended for new configurations.
