# IDGen (Unique Identifier Generator)

> Use this tool when you need to generate unique identifiers for various applications, such as database entries or tracking systems. IDGen solves the problem of creating distinct IDs by providing four generation tools: UUID, XID, ULID, and shortuuid, through a simple stdio-based interface. It takes input requests and outputs unique identifiers, making it ideal for use in distributed systems or AI assistants that require robust identification capabilities.

## Description

idgen-mcp-server is a Go-based MCP server that generates various types of unique identifiers through a simple interface. Developed by syumai, it provides four distinct ID generation tools: UUID (v4), XID, ULID, and shortuuid, each with specific characteristics suitable for different identification needs. The server uses the mark3labs/mcp-go framework to expose these tools via a stdio-based transport layer, making it easy to integrate with AI assistants that need to generate unique identifiers for database entries, tracking systems, or distributed applications without implementing complex ID generation logic themselves.
