Make 3D browser games with Meshy MCP and arcadegnt

Your assistant can write a whole 3D game with arcadegnt, but a racer full of grey boxes still looks like a prototype. Meshy fixes that. It turns a sentence or a photo into a textured 3D model, and it can rig and animate characters too. Connect the Meshy MCP server in the same chat as arcadegnt and your assistant makes the models, brings them into your game and tests the result in a real browser, all in one conversation.

What you get

• Characters from a sentence. "A chunky robot mascot with an orange visor" becomes a textured .glb your game can load.
• Rigging and animation. Meshy rigs humanoid characters and adds walk and run cycles, so the player character moves instead of sliding.
• Whole prop sets. Crates, barrels, signs, trees and pickups in one style, so the level looks like it belongs together.
• Image to 3D. Sketch a ship or snap a photo of a toy, and Meshy builds a model from it.
• Retexturing. Keep the shape and change the look: a rusty version of the car for the night track, or a gold version for the boss.

arcadegnt does the rest. It imports each model into the Godot project, checks its size and angles so the assistant knows how to place it, builds the game, and plays it on a desktop and a phone, sending back screenshots.

Set it up

You need two connectors in the same assistant: arcadegnt and Meshy.

1. Connect arcadegnt

Add https://arcadegnt.com/mcp as a connector. The steps for each assistant are on the home page.

2. Get a Meshy account

Sign up with this invite link. The MCP server needs an API key, which comes with Meshy's Pro plan or above. Create the key in your Meshy account settings.

3. Add the Meshy MCP server

It runs on your computer and needs Node.js 18 or later, so use an assistant that runs local MCP servers: Claude Code, Claude Desktop, Codex, Cursor or VS Code. In Claude Code:

claude mcp add-json meshy '{"command":"npx","args":["-y","@meshy-ai/meshy-mcp-server"],"env":{"MESHY_API_KEY":"msy_YOUR_API_KEY"}}'

Meshy's MCP page has a one-command installer that finds every assistant on your computer and sets each one up.

4. Restart your assistant

Then check that both servers are listed (/mcp in Claude Code).

Your first game with Meshy models

Paste a prompt like this one:

Make a 3D arena game with arcadegnt. Use Meshy to make the player, a small round
robot with an orange visor, rigged with a run animation, and three enemy drones in
the same style. Low poly, bright colors. Import the models, build the game and
check it on desktop and phone.

Your assistant will:

1. Generate each model with Meshy, then rig and animate the robot.
2. Pass each download link to arcadegnt's import_asset, which saves it under assets/ in your game. Meshy's download links expire, so the assistant imports them right away.
3. Look at each model with view_asset to learn its size and which way it faces.
4. Write the game in Godot, load the models, play the run animation when the robot moves, and build.
5. Play the game with check_game on a desktop and a phone, look at the screenshots, and fix what is off.

You get a link like https://robot-arena.arcadegnt-play.com/ that anyone can open on a computer or phone.

Tips for better results

• Pick one style and repeat it. Use the same words in every prompt ("low poly, bright colors, soft shading") so the models match.
• Ask for .glb. It carries the mesh, textures and animations in one file and loads cleanly in Godot.
• Keep models light. Players open your game on phones. Ask Meshy to remesh to a lower polygon count for small props, and keep each file under 25 MB (a game can hold 150 MB in total).
• Generate the hero first. Get the main character right, then make the rest of the set to match it.
• Check your credits. Every Meshy generation uses API credits. Ask your assistant to check your balance before a big batch.

Game ideas to try

• A split-screen kart racer where kaiju drive the karts.
• A haunted mansion you explore with a flashlight, full of Meshy furniture.
• A tower defense game with a set of matching turrets and creeps.
• A pet park where each animal is made from a photo of a real toy.

When the game is ready, ask your assistant to submit it to the arcadegnt gallery so other people can play it.
