What is Uuid Mcp

uuid-mcp is a Model Context Protocol (MCP) server designed to generate timestamp-based UUIDs (Universally Unique Identifiers) whenever requested by a language model.

Use cases

Use cases for uuid-mcp include generating unique identifiers for database entries, session management in web applications, and ensuring uniqueness in distributed systems.

How to use

To use uuid-mcp, install the necessary dependencies with ‘npm install’, build the project using ‘npm run build’, and start the server with ‘npm start’. For integration with Claude Desktop, add the server configuration to the Claude Desktop config file and restart the application.

Key features

Key features of uuid-mcp include: a single tool ‘generateUuid’, utilization of UUID v7 for timestamp-based unique identifiers, a simple interface requiring no input parameters, and easy integration with Claude and other language models.

Where to use

uuid-mcp can be used in various fields that require unique identification, such as software development, data management, and any application needing reliable UUID generation.

UUID MCP Provider

A simple Model Context Protocol (MCP) server that provides timestamp-based UUIDs whenever it’s called by an LLM.

Features

• Provides a single tool: generateUuid
• Uses UUID v7 for timestamp-based unique identifiers
• Simple interface with no input parameters needed
• Easy integration with Claude and other LLMs

Installation

# Install dependencies
npm install

# Build the project
npm run build

Usage

You can run the server directly:

npm start

Integration with Claude Desktop

To integrate with Claude Desktop, add this to your Claude Desktop configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "uuid-provider": {
      "command": "node",
      "args": [
        "/absolute/path/to/uuid-mcp/build/index.js"
      ]
    }
  }
}

Replace /absolute/path/to/uuid-mcp/build/index.js with the absolute path to your built index.js file.

After updating the configuration, restart Claude Desktop to see the UUID generation tool available.

How It Works

This server uses the official uuid package to generate UUID v7 identifiers. UUID v7 is specifically designed to be timestamp-based while maintaining strong uniqueness guarantees:

• Incorporates a Unix timestamp in millisecond precision
• Adds randomized data to ensure uniqueness even when multiple IDs are generated in the same millisecond
• Follows the latest RFC standards for UUID generation
• Provides chronologically sortable identifiers
• Prevents collisions in distributed systems

This approach is more reliable than custom UUID implementations and eliminates the potential for duplicates even under high load.

Dependencies

• @modelcontextprotocol/sdk: For MCP server implementation
• uuid: For RFC-compliant UUID generation
• TypeScript and related tools for development

Example

When called, the tool returns a UUID v7 string that looks like:

018e94d2-279b-7bd3-9289-80d1e6619670

The first part of the UUID contains the timestamp, making these identifiers chronologically sortable while still maintaining the standard UUID format.
