Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

A Model Context Protocol (MCP) server for interacting with Sketchfab's 3D model platform. This MCP allows you to search, view details, and download 3D models from Sketchfab directly through Claude or Cursor.

Features

  • Search for 3D Models: Find models on Sketchfab using keywords, tags, and categories
  • View Model Details: Get comprehensive information about specific models
  • Download Models: Download models in various formats (gltf, glb, usdz, source)

Prerequisites

  • Node.js 18 or higher
  • A Sketchfab API key (for authentication)

Installation

  1. Clone this repository
  2. Install dependencies:
npm install
  1. Build the project:
npm run build

Usage

Running the MCP Server

npm start

To provide your Sketchfab API key, use the --api-key parameter:

node build/index.js --api-key YOUR_API_KEY

Alternatively, you can set the SKETCHFAB_API_KEY environment variable:

export SKETCHFAB_API_KEY=YOUR_API_KEY
npm start

Questions

What is the Sketchfab MCP server?

This is an MCP (Model Context Protocol) Server for discovering and downloading 3D models

What tools does Sketchfab expose?

4 in total: 4 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Sketchfab safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Sketchfab need?

It reads SKETCHFAB_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Sketchfab run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as sketchfab-mcp-server at 1.0.10.

How current is this page?

The grade is for one exact copy of the source (140043ca0352), read on 2026-10-08. The repository is watched and re-audited when it changes.
