[Open free3d.io](https://free3d.io/#gsc.tab=0)

## Ask an agent to

-   List 3D model categories related to furniture
-   Open the vehicles category page

When we loaded free3d.io again on Oct 24, 2026, it registered these through `navigator.modelContext` or `provideContext()`, from earlier WebMCP drafts. Chrome 154 only offers `document.modelContext`, so Chrome’s own agent support does not see them.

-   `get_model_public_card`
    
    Fetch public JSON metadata for a model by 8-character hash (no download URL).
    
    model\_id: string
    
-   `get_site_policy`
    
    Return the machine-readable LLM agent policy and x402 payment instructions for free3d.io.
    
-   `get_x402_pricing`
    
    Fetch x402 pricing.json with accepted networks, tokens, and API key plans.
    
-   `open_category`
    
    Navigate to a category page by numeric category id.
    
    category\_id: integer
