Is OpenArt MCP Free? Claude Setup and Pricing

Short answer: connecting OpenArt MCP to Claude costs nothing, but the images and videos it makes are not free. Every generation spends credits from your OpenArt account, the same credits you would use on openart.ai, and a new account only gets 40 trial credits that expire after 7 days. After that you need a paid plan, which starts at $14 a month. On top of that, Claude itself has to be on a plan that allows custom connectors, so "free" really means free to connect, paid to create.

This breakdown, current as of October 2026, shows what you get for nothing, what each plan buys, how to wire the connector into Claude, Claude Code and Cursor, and where credits disappear faster than most people expect.

Is OpenArt MCP Free or Paid?

What the connector itself costs

The connector is just a URL: https://mcp.openart.ai/mcp. Adding it to Claude costs nothing, and there is no API credential to create, because you sign in with your regular OpenArt account through OAuth. OpenArt's MCP page states that generations through MCP "spend the same credits as if you're generating on openart.ai". There is no per-call fee, no add-on tier and no separate invoice.

What actually spends credits

Anything Claude asks OpenArt to produce draws from your balance:

• Images from text prompts, plus edits such as background swaps and relighting
• Video clips from text, from a still image, or from reference elements
• Character creation, which one third-party tutorial describes as a small one-time cost that you can reuse for free afterward

The price of each item depends on the model and the resolution you pick. A 4K clip from a premium video model and a small draft image sit at opposite ends of the scale.

Two bills, not one

Two meters are running at the same time. OpenArt bills the credits. Anthropic bills the Claude plan, and OpenArt's page lists the connector for personal Claude Pro and Max plans as well as team and enterprise plans, where an admin has to approve it on managed workplace accounts. If you are on Claude's free tier, check Anthropic's current connector rules before you count on this working.

💡 Tip: During setup Claude offers an "Always Allow" permission. It is convenient, but it also lets Claude spend credits without asking first. Keep approvals on until you know how quickly your balance moves.

Here is the whole picture in one table:

What 40 Trial Credits Actually Buy

The seven day clock

OpenArt's Claude page says new accounts get 40 free trial credits to be spent within 7 days, no credit card required. Unused credits do not wait around for you. If you create the account on a Monday and test on the following Tuesday, the balance may already be gone, so sign up when you are ready to run real prompts.

Images versus video math

OpenArt does not publish a flat price per generation, and that is on purpose: it varies by model and resolution. Two data points help anyway.

• One third-party tutorial puts an ordinary image near 1 credit, with video clips costing "much higher".
• OpenArt's own plan listings say 4,000 credits buy "up to ~50 videos". That works out to roughly 80 credits per video in the best case (my arithmetic, using the cheapest video model).

The trial is enough to judge whether the image workflow suits you. It is not enough to judge video, which is where most of the money goes.

OpenArt Plans in Plain Numbers

Prices below come from OpenArt's pricing page as checked in October 2026. Some third-party reviews still use older plan names such as "Essential" for the $14 tier, so trust the pricing page over a blog post, including this one, when the two disagree.

The video estimates exclude OpenArt's Director feature, and the cost per 1,000 credits is my own division of price by credits on the monthly rate.

Which plan fits which user

• Curious tester: stay on the trial, then pick Starter if image results satisfy you.
• Freelancer shipping images weekly: Plus gives three times the credits of Starter for about $20 more, and the per-credit price drops by roughly 19%.
• Anyone animating stills regularly: Pro or Wonder. Video burns credits at about 80 per clip, so the cheaper per-credit rate matters most here.

A quick worked example, using the rough estimates above. A small channel that makes 30 images and 10 clips a month needs about 30 + 800 = 830 credits, which fits inside Starter's 4,000 with room to spare. A studio that animates 40 clips a month needs about 3,200 credits for the clips alone, which uses most of a Starter allowance before a single image is counted. Because real video prices vary by model, treat these as planning numbers and watch your balance during the first week.

Check commercial rights first

The pricing page lists commercial use rights on Plus, Pro and Wonder. Starter's listing does not mention them. One tutorial claims a different plan name is required, so the sources conflict. Confirm on the pricing page and in OpenArt's terms before you deliver anything to a paying client.

Claude Setup in Five Minutes

Claude web and desktop

OpenArt describes this as a one-minute job. Allow five if you are creating the account at the same time.

1. Create a free OpenArt account at openart.ai.
2. In Claude, open Settings, then Connectors, then Add custom connector.
3. Name it OpenArt and paste https://mcp.openart.ai/mcp. Leave the optional settings blank.
4. Click Connect and sign in to OpenArt when the OAuth window opens.
5. Choose the permission level you want for the OpenArt tools.
6. Ask for something, for example: "Generate a 16:9 photo of a foggy pine forest at dawn, then animate it into a 6 second clip."

Claude picks a model automatically unless you name one, and finished files also land in your OpenArt library. Generation runs in the background, so the chat stays usable while you wait.

To confirm the connection worked before you spend anything, ask Claude which OpenArt tools it can see. If it lists image and video tools, you are connected. If it answers that it has no such tools, start a new chat, because a connector added mid-conversation is sometimes missed.

Claude Code from the terminal

Claude Code accepts remote servers through its standard command. Using OpenArt's URL, it looks like this:

claude mcp add --transport http openart https://mcp.openart.ai/mcp

Copy Prompt

Then open a Claude Code session, run /mcp, pick the OpenArt entry and finish the sign-in in your browser. OpenArt's own pages concentrate on the Connectors screen, so if your version of Claude Code words the command differently, run claude mcp add --help to confirm the flags. OpenArt also ships a standalone command line tool: run its install script, then openart login.

Cursor and other clients

The pattern never changes: one URL plus OAuth. In Cursor, open Settings, then MCP, add a new server, paste the URL and authenticate. OpenArt lists ChatGPT and Kimi as supported too, and any other client that speaks the Model Context Protocol should work the same way. The command line tool suits scripted jobs, such as generating a batch of product shots overnight, but it spends the same credits, so a loop with a typo in it can be an expensive typo.

Fixing sign-in problems

Most failed connections come down to a short list:

• A typo in the URL, or optional fields filled in when they should be empty
• A balance that reads zero because the 7 day trial window already closed
• A blocked pop-up, so the OAuth window never appears
• A managed Claude workspace where an admin has not approved custom connectors
• Authorizing the wrong OpenArt account, which means credits come out of a different balance than you expected

If nothing works, remove the connector, add it again and reconnect.

Models Behind the Connector

OpenArt's pages do not list identical lineups, and the roster changes as models launch, so read this as an October 2026 snapshot. One fact explains why connectors like this exist: Claude does not generate images or video by itself, so it hands the job to an outside generator and shows you the result.

Image models. The main MCP page names GPT Image 2.5, Nano Banana 2, Seedream 5.0 Pro, Grok Imagine and Qwen Image 3. The Claude page adds GPT Image 2, Nano Banana Pro and Seedream 5 Pro to the mix. If you want to compare how these models handle your own prompts without spending connector credits, each has a page on PicassoIA, linked in the table below.

Video models. For video, OpenArt names Seedance, Kling, Sora, Wan, LTX, PixVerse and Gemini Omni variants across its pages. Clips run up to 4K, typically about 6 seconds, and Claude can work in three modes: text to video, image to video with start and end frame guidance, and element to video for keeping one subject consistent across scenes. A Smart Shot option also chains several cuts into a short storyboard, which is handy for ads but spends credits for every cut.

Prompting through Claude. You do not have to write the final prompt yourself, because Claude will turn a plain request into one. Specifics still win. Name the lens, the light direction, the setting and the aspect ratio, and say which model you want when you have a favourite. A request like "photoreal, 35mm, overcast window light, 16:9" plus a named model such as Seedream 5 Pro gets a more predictable result than "make it look nice", and a predictable first try is the cheapest kind.

Where Credits Disappear Fast

Three common mistakes

1. Open-ended requests with approvals off. "Give me ten variations" can mean ten paid generations before you read the first one.
2. Jumping straight to video. A clip costs far more than a still. Approve the still first, then animate that exact image.
3. Using the top model for drafts. Resolution and model both move the price, and a rough draft does not need either at maximum.

💡 Tip: Ask Claude to name the model and resolution it plans to use before it generates anything. The answer takes two seconds and often saves a few hundred credits.

A cheaper iteration routine

1. Draft at a lower resolution until the composition is right.
2. Lock one winner and re-run it at final quality.
3. Animate only that winner.
4. Keep a short note of prompts that worked, so the next project starts with proven wording.

OpenArt MCP vs the PicassoIA Connector

OpenArt is not the only generator you can attach to Claude. PicassoIA offers its own connector and a Replicate style developer API at https://api.picassoia.com/v1, authenticated with a bearer token. The connector exposes four models: PicassoIA Image, PicassoIA Image Editor Pro, PicassoIA Video and Seedance 2.5 Lite for video with audio.

Side by side

OpenArt wins on breadth of models through a single connector. PicassoIA's list is shorter. Which plan includes connector access is spelled out on the PicassoIA pricing page, and it is worth checking there before you plan a workflow around it.

Use GPT Image 2 on PicassoIA

You do not need any connector to test a model. The browser route takes a minute:

1. Open the GPT Image 2 page.
2. Write a prompt that names the subject, the lens and the light, for example "85mm portrait of a ceramicist at work, window light from the left, film grain".
3. Set the aspect ratio to 16:9 for a banner or 9:16 for a vertical post.
4. Generate, compare the result with what Claude produced through OpenArt, and keep the better one.
5. Send the winner to Seedance 2.0 if you want it to move.

Try Your Own Images on Picasso IA

The cheapest way to decide whether paid credits are worth it is to run the same prompt through several models first. Picasso IA puts image, video and speech models in one place, so you can test a prompt, change one word, and see the difference without any setup. Start with GPT Image 2 or PicassoIA Image Editor Pro, then browse the full model list at picassoia.com/en/all-models.

Pick one scene from your next project, write three prompt versions, and compare them side by side. You will know within ten minutes which model matches your style, and which paid plan, if any, deserves your money.
