# Three.js 3D Viewer — AI Connector Three.js 3D Viewer in the Claude connectors directory: what it exposes, how Claude reaches it, and its verification tier. Source: https://node8.ai/ai-connectors/developer-tools/three-js-3d-viewer/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Developer Tools](https://node8.ai/ai-connectors/developer-tools/) # Three.js 3D Viewer Demo viewer that renders Three.js scenes in the conversation Listed in Claude · Tool count not reported · Verified partner [Claude connector docs](https://github.com/modelcontextprotocol/ext-apps/blob/main/examples/pdf-server/README.md) [modelcontextprotocol.io](https://modelcontextprotocol.io) Overview ## What Three.js 3D Viewer does This is a demonstration connector from the Model Context Protocol community rather than a product. It renders interactive 3D scenes with Three.js and displays them inline, so a scene described in conversation arrives as something that can be rotated and inspected instead of as a code block to copy elsewhere. Transparent backgrounds are supported. A second call returns Three.js documentation and examples, which makes the pairing self-contained: read how the library works, then render the result. Nothing persists between sessions and there is no account to connect. The listing publishes a tool count of zero, which the endpoint contradicts. ### Who it is for Developers exploring what an interactive rendered output can do in a session. ### Tool surface The listing records zero tools while the endpoint returned two: show\_threejs\_scene, which renders custom Three.js code, and learn\_threejs, which returns documentation for writing that code. The reference call exists because the render call expects working code as its input. Availability ## Where Three.js 3D Viewer is listed Three.js 3D Viewer is listed in the Claude connectors directory only. Model Context Protocol Community has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Three.js 3D Viewer reports no tool count in its Claude directory listing. 9 of the 1,253 Claude-listed connectors are in the same position, which is far more likely to be a gap in the listing than a server with nothing on it. Claude-listed connectors filed under Developer Tools have a median of 13 published tools, so that is the closest thing to an expectation until the endpoint is probed directly. ### Measured against the live endpoint A direct call to the endpoint returned 2 tools. Probed 2026-08-07. #### Tools the server actually returns - `show_threejs_scene` - `learn_threejs` Three.js 3D Viewer publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Model Context Protocol Community Verification Verified partner (37.8% of the Claude directory) Filed under Developer Tools Endpoint `https://example-server.modelcontextprotocol.io/threejs/mcp` Documentation [Publisher setup docs](https://github.com/modelcontextprotocol/ext-apps/blob/main/examples/pdf-server/README.md) Snapshot August 2026 Three.js 3D Viewer carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How Model Context Protocol Community describes it > Demo interactive 3D viewer powered by Three.js, a popular JavaScript library for rendering 3D graphics in the browser. Generates and displays 3D scenes, models, and animations directly in the conversation. Quoted from the connector's own Claude directory listing as captured in August 2026. Node8 did not write it and does not vouch for it.
