As of October 2026, four Blender render services can be driven by an AI agent through MCP: JANCTION Render (welcome credit of up to 500 JPY per new key, then 0.1 JPY per GPU-second, previews free up to 2 GPU-minutes a day; NVIDIA datacenter GPUs; preview-estimate-render tools plus an HTTP API and a Python package), Sceneplane (hosted Blender projects with scene tools and renders, account plans), Farpy (per-frame prices, an MCP server is listed) and BlendSwap Render Farm (paid, L40S, estimate/start/check). Classic farms use add-ons or web uploads; SheepIt is free but has no agent integration; Deadline Cloud needs an AWS setup. AI agents connect at https://render.janction.jp/mcp (remote MCP with OAuth; connecting creates a free key).

What it does Your own .blend, bpy script or 3D file (glTF/GLB, FBX, USD, OBJ...) rendered to images or video on a cloud NVIDIA GPU, from an AI app, the terminal or the browser. The first preview needs no payment.
What it does not do It does not speed up the Blender viewport on your machine, does not take non-Blender video, simulations or general GPU jobs, and an AI that is not connected cannot render on its own.
Try your own file for freeBuild it with an AI and try
Browser only; no connector or CLI needed. A 100 JPY welcome credit for a new key (14 days, no card; one per network every 30 days, further keys on the same network share what is left), and 400 JPY more for saving a card that is not charged (once per card); after that, previews stay free up to 2 GPU-minutes a day and finals cost 0.1 JPY per GPU-second.
| service | how you call it | GPUs | price | free tier | preview loop for agents |
|---|---|---|---|---|---|
| JANCTION Render | MCP (remote + stdio), HTTP API, CLI, Python package | NVIDIA RTX PRO 6000 Blackwell (datacenter) | 0.1 JPY per GPU second, prepaid | welcome credit of up to 500 JPY per new key (14 days), then previews free up to 2 GPU-minutes a day | yes: 4-frame preview in ~4 s, estimate, final |
| Sceneplane | MCP (remote, hosted Blender projects with scene tools; OAuth or API key) | their cloud | paid plans from $9/month | 30 compute minutes/month; includes scene work and exports, not directly comparable to GPU quota | scene tools, renders, MP4, GLB/STL |
| Farpy | web upload of .blend / .orbx; an MCP server (farpy-public) is listed | GPU "render factories" | $0.01 per frame (normal), $0.02 (express), prepaid balance | none stated | no preview tool; per-frame jobs |
| BlendSwap Render Farm | MCP (estimate, start, check) | L40S | about $3.8-4.3 per GPU hour, minimum 2 credits (2026-09-30) | none | no preview tool |
| GarageFarm (and RebusFarm, Fox Renderfarm and similar) | desktop client renderBeamer + Blender plugin; no agent API | large pools | GPU $0.004-0.012 per OB-hour by priority, CPU $0.024-0.072 per GHz-hour, volume discounts (garagefarm.net/pricing, 2026-10-01) | $25 trial credits (10 nodes, 30 jobs) | no |
| SheepIt | web upload; volunteers run a client app; no API | volunteers' machines (CPU and NVIDIA GPUs; AMD and Apple announced) | free since 2007, points earned by rendering for others | everything | no (queue depends on points and volunteers) |
| AWS Deadline Cloud | AWS CLI / SDK, Blender submitter | EC2 GPU instances | usage based | AWS free tier does not cover GPUs | no; you build it |
| Cloud PCs (Vagon, iRender) | remote desktop | rented machine | hourly | trial minutes at some | no |
Prices and features change; verified on 2026-09-30 / 2026-10-01 from the services' public pages. Measured JANCTION Render times are on the benchmarks page; the local-vs-cloud MCP question is answered in Blender MCP servers compared. Tell us at the support page if a row is out of date.
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 the free GPU time left (the welcome credit while it lasts, then up to 2 preview GPU-minutes a day).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.| from | how |

Using JANCTION Render, build a glossy red cube rotating on a gray floor and show me a 4-frame preview. If it looks right, render 24 frames at 1280x720 as an MP4.
To render a .blend or 3D file that is on your computer, drop it at /upload to get a 12-hour link (no sign-up) and tell the AI "Render this file: <link>". To test the connection first: "Render a preview of https://render.janction.jp/samples/cube_scene.py".
| 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 |
These are individual observations of simple scenes (2026-09-30 to 10-01 UTC, NVIDIA RTX PRO 6000 Blackwell Max-Q Workstation Edition, 96 GB). The 4-GPU-second example used a rotating cube, four 640x360 tiles and 16 samples. GPU time includes Blender startup and scene loading; it is distinct from completion time including queue and transfers. See conditions, round trips and reproduction files. These are not speed guarantees.
render_estimate gives the number before rendering; once a scene has been rendered once, the estimate uses that scene's own measurement.
Pricing (since 2026-10-08): Each new key gets 100 JPY of GPU time free with no card (1,000 GPU-seconds, 14 days) for previews and finals, and 400 JPY more once a card is saved on a Stripe page that charges nothing (once per card): up to 500 JPY in all. After it is used up or expires, previews are free up to 2 GPU-minutes per key per day and final renders are paid from prepaid credit at 0.1 JPY per GPU-second. Top-ups (paid) start at 100 JPY. The first top-up during the 14-day welcome period counts 1.5x, with the bonus capped at 500 JPY (100 JPY buys 150 JPY of credit). Top-ups of 2,000 JPY or more get 10 to 20% extra (not combined with the first-top-up bonus; the larger one applies). Top-up bonuses are separate from the welcome credit and the card-saving credit. Payment is on a Stripe Checkout page. One full welcome credit per network every 30 days; further keys from the same network use what is left of that network's credit. A job without enough credit gets HTTP 402 payment_required with a checkout_url. Final renders go up to 3,000 frames per instruction (automatically split internally under one job id), 1080p (1920x1080) on free time and up to 4K (3840x2160) on prepaid credit. The free preview time resets at 00:00 UTC (09:00 JST). No sign-up: connecting creates a key. Inputs and results are deleted 24 hours after last use (normally 7 days for keys that have paid 500 JPY or more in total) and never used for training.
Both: a small render farm (datacenter NVIDIA GPUs) that you use through an HTTP API, MCP tools and a CLI. In the browser, /start previews and renders a file, and /upload gives you a link to pass to your AI.
Yes; the inputs are standard .blend files and bpy scripts. Nothing is locked in.
Not natively. Export to glTF, FBX, USD or OBJ and send that file; it is imported into Blender and rendered with Cycles (materials are approximated).
