PolyHaven MCP Server

An Model Context Protocol (MCP) server that provides agents and AI assistants access to the PolyHaven 3D asset library.

This server allows you to search, query, and retrieve download links for high-quality, CC0 HDRIs, textures, and 3D models directly through your AI assistant.

Features

This server exposes several tools that map directly to the PolyHaven public API:

• get_asset_types: Lists available asset types (hdris, textures, models).

• search_assets: Search for assets, optionally filtered by type and categories.

• get_asset_info: Retrieve detailed metadata and information about a specific asset by its ID.

• get_asset_files: Get a list of files for a specific asset, including direct download URLs for various formats and resolutions.

• get_categories: View available categories for a given asset type (and their asset counts).

• get_author_info: Retrieve information about a specific author.

Usage with MCP Clients

To use this server with an MCP-compatible client (such as Claude Desktop or Antigravity), you need to configure your client to launch the server.

Example Configuration

Add the following to your MCP client's configuration file:

{
  "mcpServers": {
    "polyhaven": {
      "command": "node",
      "args": [
        "/absolute/path/to/polyhaven-mcp/build/index.js"
      ]
    }
  }
}

Make sure to replace /absolute/path/to/polyhaven-mcp/build/index.js with the actual path to the compiled index.js file on your system.
