Drive 3dCMS from Claude
The MCP server lets Claude (in Desktop, Code, or the terminal) build and edit your saved scenes using your existing Claude subscription.
Open in the interactive manual →The interactive version has full-text search, a table of contents, and light/dark themes.
The MCP server is the mirror image of the in-editor Assistant. Instead of chatting inside the editor on an API key, you chat with Claude Desktop or Claude Code (on your existing Claude subscription), and Claude builds and edits your saved scenes on your account. Anything Claude makes appears the next time you open that scene in the editor, and vice-versa.
| In-editor Assistant | MCP server | |
|---|---|---|
| Where you chat | The editor panel | Claude Desktop / Code |
| Who pays for the AI | Your Anthropic API key | Your Claude subscription |
| What it edits | The scene open in the editor | Your saved scenes |
Two ways in
There are two routes, and the first one needs nothing installed:
| Hosted connector | Local server | |
|---|---|---|
| What you add | A URL: https://3dcms.info/mcp | The mcp-server/ folder on your own machine |
| How you sign in | Google, in your browser, once | An API token you paste into a config file |
| Needs Node? | No | Yes, Node 18+ |
| Tools | The 6 core tools | All 8, including the paid generation tools |
Start with the hosted connector unless you specifically want generate_3d and generate_material, which need your own fal.ai key on your own machine. Either way, Connect Claude has the steps. (MCP stands for Model Context Protocol, the open standard Claude uses to connect to external tools.)
3dCMS is listed in the official MCP registry as info.3dcms/mcp, and directories that crawl that registry (Smithery and Glama) carry it too, so some clients can find it without you typing a URL at all.
