3D assets for AI agents

Gaitkit runs a public MCP server at https://gaitkit.com/mcp, so AI coding agents such as Claude Code, Cursor, Codex and VS Code can search the catalogue, turn plain words into knob values and get working three.js code or GLB links. Browsing needs no key.

How it works

When an agent builds a game or a 3D page, it usually draws boxes and spheres. With the Gaitkit MCP server it can ask for "a red pickup truck" or "a spider that walks", get the closest specimen with the knob values that match, and write the import line for you. The tools are search_assets, get_asset, get_variant, report_need and who_am_i.

Search is honest: it grades its own coverage, and when nothing fits it says so and logs the request with report_need instead of offering something unrelated. There is also a REST API and a plain-text llms.txt for agents that read the web directly.

Questions

Is there an MCP server for 3D models?

Yes. Gaitkit serves one at https://gaitkit.com/mcp over Streamable HTTP; it lists low-poly 3D assets with knobs, code and GLB links.

Do I need an API key?

No key is needed to search and read assets. An API key in the Authorization header adds your plan, so Pro download links work for your agent.

Which agents work with it?

Any MCP client that supports HTTP servers, including Claude Code, Cursor, Codex, VS Code and Windsurf. The agents page has an install line for each.

What happens when the agent asks for something that does not exist?

search_assets reports coverage as poor or none, and the agent can call report_need so the request joins the build queue.
