In Claude.ai, add https://render.janction.jp/mcp as a custom connector (Settings → Connectors → Add custom connector). Press Connect, and a free key is created. Then describe a scene: Claude writes the bpy script, previews it on a JANCTION GPU in a few seconds and renders the final MP4. Free beta.
https://render.janction.jp/mcp, Add.The connector is also submitted to Anthropic's connector directory (in review as of 2026-10-02); once listed, it can be enabled without pasting a URL.
Using JANCTION Render, build a glossy red cube rotating on a grey floor and show me a 4-frame preview. If it looks right, render 24 frames at 1280x720 as an MP4.
scene_info reads the scene without rendering: cameras, frame range, objects, missing files.render_preview renders 1-4 frames at 720p in a few GPU seconds and returns the image, so the agent can look, fix the script and try again.render_estimate says how long the final render takes ("about 3 minutes") and whether it fits today's free quota.render_final renders the frames on GPUs and joins them into an MP4; render_status reports the remaining time; render_download returns the files or links.A 40-second recording of this exact flow: demo.mp4.
| job | GPU time | note |
|---|---|---|
| preview, 4 frames (720p split in 4 tiles, 16 samples, denoised) | about 4 s | round trip about 8 s; the image comes back inline |
| final, 24 frames at 1280x720, 64 samples → MP4 | about 60 s | measured 2026-09-30 / 10-01 (59 s and 58 s) |
| final, one 1920x1080 frame at 128 samples | about 11 s | the estimator's baseline; heavy scenes take longer |
render_estimate gives the number before rendering; once a scene has been rendered once, the estimate uses that scene's own measurement.
Free beta (as of 2026-10-02): 10 GPU-minutes per key per day (20 per network), final renders up to 240 frames at 1080p. No sign-up: connecting creates a key. Inputs and results are deleted 24 hours after last use and never used for training. Paid plans will be announced on this site and in llms.txt before they start.
Claude Code (terminal) uses claude mcp add --transport http janction-render https://render.janction.jp/mcp or the stdio server for local files; see
Claude Code + Blender. The Claude desktop and mobile apps share the connectors you add on claude.ai.
Custom connectors are available on paid Claude plans (Pro, Max, Team, Enterprise) as of October 2026; check Anthropic's help center for the current list.
Yes. render_preview returns the image inline, so Claude can judge the camera, lighting and materials and fix the script before the final render.
render_download returns links that need no key and work for about 24 hours. Open them in the browser or let Claude show them.
