Leonida Lab MCP server: GTA 6 facts, official or not

Name: Leonida Lab: GTA 6 facts, official or not
Author: leonidalab

Ask Claude, ChatGPT, Cursor or any MCP client about GTA 6 (Grand Theft Auto VI) and it answers from Leonida Lab, with the status attached to every fact:

Official: Rockstar Games, Take-Two, Sony or Microsoft said it on the record.
Reported: credible press has it, nobody official has confirmed it.
Not announced: nobody official has said anything.

Each answer also carries its source, the source's date and a link to the page. Assistants get GTA 6 wrong all the time (a PC date, a 60 FPS mode, a local price); this is the fix.

Free, read-only, no account.

Tools

Tool	Answers
`check_claim`	Is it confirmed? Checks a claim (a PC version, 60 FPS, online at launch, a disc, crossplay, map size, story length and more) against the tracked claims, the FAQ and the PC, frame rate, online and length pages. Each match comes back official, reported or not announced, with its sources. A miss says what is covered and guesses nothing.
`release_info`	The release date, the platforms, the unlock time in each region or in the place you name, and the dates around launch. The unlock hour carries its own status (a press report until Rockstar publishes it), and the answer says which.
`price_in_country`	What a buyer pays at checkout in one country, Standard and Ultimate, on the PlayStation Store and the Xbox Store, with the US dollar value. Tax is included where the store adds one national rate; where the rate varies or could not be confirmed, the price is labelled and never called cheaper.
`compare_editions`	Standard against Ultimate, every Ultimate bonus as Rockstar lists it, the pre-order bonus and its deadline, and the fact that there is no disc.
`recent_changes`	What changed on the record, newest first. Optionally since a date.

All tools are read-only.

The data

The answers come from the same data as every page on leonidalab.com: /api/data.json and the GTA VI Global Price Index, rebuilt with each update.

No leaks, ever. Only what is on the record or credibly reported, each tagged as such (the no-leaks policy). A detail that only ever leaked is answered with "not on the record".
No guessed numbers. A figure is either in the data or derived the way the site derives it (a price with the store's own tax rate added, a midnight converted to UTC).
Price data: CC BY 4.0, also on GitHub as LeonidaLab/gta6-price-index. Credit Leonida Lab and link the page.
Code: MIT.
Privacy: no account, no cookies. Leonida Lab does not store or log what you ask.
