# framebench MCP server
Ask whether a machine can run a game, and get a number back.
**framebench** answers "can this PC or Mac run this game" with an estimated **fps range** for any
GPU or Apple Silicon chip across the most played games on Steam, plus which component limits you
and the settings that raise it. Every response carries a citable URL.
- **Hosted endpoint:** `https://framebench.app/mcp` (Streamable HTTP) — no key, no account
- **Website:** <https://framebench.app> · **Docs:** <https://framebench.app/mcp-docs/>
- **Official MCP Registry:** `app.framebench/framebench`
## Use it
Most clients can point straight at the hosted endpoint:
```json
{
"mcpServers": {
"framebench": { "url": "https://framebench.app/mcp" }
}
}
```
For clients that only support local (stdio) servers, this repo is a dependency-free bridge:
```json
{
"mcpServers": {
"framebench": { "command": "npx", "args": ["-y", "framebench-mcp"] }
}
}
```
Or with Docker:
```bash
docker build -t framebench-mcp . && docker run --rm -i framebench-mcp
```
## Tools
### `check_game`
Can this rig run this game? Returns an fps range (never a single number or a fake percentage),
the limiting component, levers that change the outcome, a confidence label, and a canonical URL.
| Argument | Required | Notes |
|---|---|---|
| `game` | yes | Name or slug, e.g. `"Cyberpunk 2077"` |
| `gpu` | one of | Name or slug, e.g. `"RTX 3060"`, `"rtx-4060-laptop"` |
| `apple_chip` | one of | e.g. `"M2 Pro"` |
| `cpu` | no | Adds a CPU-limit check |
| `ram_gb` | no | Flags a shortfall against requirements |
| `resolution` | no | `1080p` (default), `1440p`, `4k` |
```jsonc
// → check_game { "game": "Elden Ring", "gpu": "RTX 3060" }
{
"game": "ELDEN RING",
"resolution": "1080p",
"fps_range": { "low": 60, "high": 90 },
"limiter": "gpu",
"confidence": "modeled",
"summary": "ELDEN RING on a GeForce RTX 3060 at 1080p, high settings: expect roughly 60–90 fps (GPU-limited).",
"url": "https://framebench.app/game/elden-ring/rtx-3060/"
}
```
### `compare`
Two GPUs, two CPUs, or a GPU against an Apple chip, on one performance index, with spec facts.
### `recommend_upgrade`
Given a rig and a target (game, resolution, fps), the smallest upgrades that clear it, ranked.
## How the numbers work
Estimates are modelled, not measured, and the site says so. Ranges come from a curated performance
index (desktop RTX 3060 = 100) scaled against each game's official Steam requirements, and widen as
confidence drops. Hard rules: laptop GPUs are separate parts with their own TGP bands rather than
aliases of desktop cards; Windows-only games on Apple Silicon get an explicit translation-layer
estimate instead of a silently copied PC number; VRAM and unified-memory cliffs override the model.
