Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

claude mcp add --transport http framebench 'https://framebench.app/mcp'

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.

Use it

Most clients can point straight at the hosted endpoint:

{
  "mcpServers": {
    "framebench": { "url": "https://framebench.app/mcp" }
  }
}

For clients that only support local (stdio) servers, this repo is a dependency-free bridge:

{
  "mcpServers": {
    "framebench": { "command": "npx", "args": ["-y", "framebench-mcp"] }
  }
}

Or with Docker:

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.

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.

Frequently asked questions

What is framebench?

Estimated game fps for any GPU or Apple Silicon chip, with the limiter and tweaks.

How do I install framebench?

It runs as a remote server. In Claude Code: claude mcp add --transport http framebench 'https://framebench.app/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does framebench need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is framebench open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains framebench?

It is published by aistripes. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
