get_uuidLABSCO SUMMARY
The point is that the model is not making it up.
Ask an assistant for a random identifier and you get a plausible-looking string with no randomness behind it — fine until two of them collide or one turns out to be memorised. Delegating it to a tool call makes the value real. There is nothing else here, and there does not need to be.
What it is
A minimal MCP server whose only job is producing a UUID. A model asked to invent an identifier produces something that looks right and is not random; this returns a real one.
What you get
- A newly generated UUID, from a call that takes no parameters at all —
get_uuid - One tool, which costs almost nothing to leave enabled alongside everything else
Requirements
Nothing — no account, no key, no network. Python 3.10 or higher and the MCP package v1.2.0 or higher; install dependencies with uv pip sync and point your client at uv with the repository directory and get-uuid.py. Use the absolute path to uv in the client config. The package is mcp-uuid (version 0.1.0). The README is written in Japanese.
Setup effort
Clone and run — clone the repository, then add the configuration for your client; uv runs the script from your clone, with nothing to build
USE CASES
01
Getting an identifier you can actually use
Ask for a UUID and get a generated one, rather than a string the model composed to look like one.
02
Seeding test data
Generate identifiers for fixtures or sample records without leaving the conversation for a terminal.
03
Filling an ID field while drafting
Get a real value for a config or a migration you are writing with the assistant, instead of a placeholder you have to remember to replace.
