Aggrometer — the gaming attention graph

MCP serverDev tools

Aggrometer shows how much attention games are getting on Steam and Twitch. Once it is added, your AI can look up player counts, live viewers, hype, the aggro ratio, and how those numbers have changed over time. It is community-maintained.

Available today. Use it from your connected AI after setup.

Add it and then ask your AI about a game you follow, such as how many people are playing it on Steam or watching it on Twitch.

Then ask your AI: use Aggrometer — the gaming attention graph to get summary

What your AI can do with it

  • Look up Steam player numbers for a game
  • Check how many people are watching a game live on Twitch
  • Look up the hype around a game
  • Check a game's aggro ratio
  • See how attention to a game has changed over time

From the project's README

As published by aggrometer/aggrometer in README.md.

Live cross-platform gaming market data for humans and AI agents. Aggrometer continuously measures ~2,000 games: Steam concurrent players (hourly) and Twitch live viewership (15-min, game-level aggregates), plus prices, discounts, top-seller ranks, clip velocity, review counts, and pre-release hype — joined per game.

Signature metric: aggro = live viewers ÷ concurrent players, same hour. Above 1.0, a game holds more audience than players — the signal that streamer marketing converts, that a spectacle moment is happening, or that attention is arriving ahead of sales.

Data notes

Game-level derived aggregates and estimates only. History accrues continuously since 2026-08-26; sparse series indicate a young warehouse, not missing coverage. Live viewership data provided by Twitch; the anticipation score is Aggrometer's own composite index (Steam wishlist rank + pre-release Twitch attention).
