🛠️ Installation

Prerequisites

• Node.js 18+
• npm or yarn

Install from npm

# Install the package
npm install sequential-guid-generator-mcp

# For global MCP server usage
npm install -g sequential-guid-generator-mcp

Local Development

# Clone the repository
git clone <repository-url>
cd GUIDMCP

# Install dependencies
npm install

# Build the project
npm run build

🚦 Usage

As an npm package

import { SequentialGuidGenerator, generateSequentialGuid, generateSequentialGuidBatch } from 'sequential-guid-generator-mcp';

// Generate a single sequential GUID
const guid = generateSequentialGuid();
console.log('Generated GUID:', guid);

// Generate multiple GUIDs
const guids = generateSequentialGuidBatch(10);
console.log('Generated batch:', guids);

// Use the generator class
const generator = new SequentialGuidGenerator();
const customGuid = generator.generate();

As MCP Server

Option 1: Using npm package globally (Recommended)

1. Install the package globally:

npm install -g sequential-guid-generator-mcp

2. Configure Claude Desktop (or other MCP-compatible client):

Add to your Claude Desktop configuration (claude_desktop_config.json):

For Windows:

{
  "mcpServers": {
    "sequential-guid-generator": {
      "command": "sequential-guid-mcp.cmd"
    }
  }
}

For macOS/Linux:

{
  "mcpServers": {
    "sequential-guid-generator": {
      "command": "sequential-guid-mcp"
    }
  }
}

3. Verify installation (optional):

# Check if the command is available
sequential-guid-mcp --version

Note: The global installation creates a command-line binary that you can call directly. The binary name matches the bin field in package.json: "sequential-guid-mcp": "dist/server.js"

Option 2: Using npm package locally

1. Install as dependency in your project:

npm install sequential-guid-generator-mcp

2. Configure Claude Desktop:

{
  "mcpServers": {
    "sequential-guid-generator": {
      "command": "node",
      "args": ["node_modules/sequential-guid-generator-mcp/dist/server.js"]
    }
  }
}

Option 3: Development from source

1. Clone and build locally:

git clone <repository-url>
cd GUIDMCP
npm install
npm run build

2. Configure Claude Desktop:

{
  "mcpServers": {
    "sequential-guid-generator": {
      "command": "node",
      "args": ["dist/server.js"],
      "cwd": "/path/to/GUIDMCP"
    }
  }
}

3. Restart Claude Desktop to load the server.

📚 API Reference

SequentialGuidGenerator

import { SequentialGuidGenerator } from './SequentialGuidGenerator';

const generator = new SequentialGuidGenerator();
const guid = generator.generate();
const batch = generator.generateBatch(100);

SqlServerOptimizations

import { SqlServerOptimizations } from './SqlServerOptimizations';

const analysis = SqlServerOptimizations.analyzeGuid(guid);
const schema = SqlServerOptimizations.generateTableSchema('Users');

🎯 SQL Server Integration

Creating Optimized Tables

-- Use sequential GUIDs for primary keys
CREATE TABLE Users (
    Id UNIQUEIDENTIFIER NOT NULL PRIMARY KEY,
    Email NVARCHAR(255) NOT NULL,
    CreatedAt DATETIME2(3) NOT NULL DEFAULT (SYSUTCDATETIME())
);

-- For SQL Server-generated GUIDs, use NEWSEQUENTIALID()
CREATE TABLE Orders (
    Id UNIQUEIDENTIFIER NOT NULL CONSTRAINT DF_Orders_Id DEFAULT (NEWSEQUENTIALID()) PRIMARY KEY,
    UserId UNIQUEIDENTIFIER NOT NULL,
    Amount DECIMAL(18,2) NOT NULL,
    CreatedAt DATETIME2(3) NOT NULL DEFAULT (SYSUTCDATETIME()),
    FOREIGN KEY (UserId) REFERENCES Users(Id)
);

Performance Monitoring

-- Check index fragmentation
SELECT 
    OBJECT_NAME(ind.OBJECT_ID) AS TableName,
    ind.name AS IndexName,
    indexstats.avg_fragmentation_in_percent
FROM sys.dm_db_index_physical_stats(DB_ID(), NULL, NULL, NULL, NULL) indexstats
INNER JOIN sys.indexes ind ON ind.object_id = indexstats.object_id;

🧪 Testing

# Run all tests
npm test

# Run tests with coverage
npm run test:coverage

# Run specific test file
