Meshy plugin for Hermes Agent: 3D models from a prompt or photo

Added NewCopyable prompt below

Published Last verified Released

Our verdict

The easiest way to get game assets, product mockups or print-ready models out of an agent you already run: one install adds Meshy's first-party MCP server plus a workflow skill, and every credit-spending call goes through Hermes's approval prompt with its estimated cost. It is not free to use: Meshy API keys need a Pro plan or above, and generation runs on Meshy's servers under your key. It was listed on 2026-10-21, so expect quick changes; we have not run it ourselves.

Who it's for
Hermes Agent users, indie game devs, 3D-print hobbyists and makers who need 3D assets without learning Blender
Leverage
Prompt-to-3D-asset pipeline inside your agent, with a cost check before each paid step
Effort
Low

What it does

The Meshy plugin is part of Hermes Official Plugins, maintained by Nous Research. One install ships an mcp.json that launches Meshy's first-party MCP server (meshy-dev/meshy-mcp-server, MIT, pinned to @meshy-ai/meshy-mcp-server@0.6.5 over npx) and a meshy-3d workflow skill that carries the server's routing rules (cost confirmation, never re-creating an uncertain task, choosing the output format first). Tools cover text, image and multi-image to 3D, texturing, remeshing, rigging, animation, format conversion, resizing, UV unwrapping, 2D concept images and 3D-print preparation. In Hermes Desktop you get inline 3D cards, a gallery of recent generations and a credit chip; a 200-credit limit per chat makes it ask again. It needs Hermes 0.22.3 or later, Node.js 18+ with npx, and MESHY_API_KEY; prompts and the images you name are sent to Meshy's API, and the plugin sends no analytics.

How builders use it

  • Install and enable it from the Nous plugin catalog: hermes plugins install meshy, then hermes plugins enable meshy.
  • Create a Meshy API key (Pro plan or above) and set it in Hermes Desktop under Settings → Plugins → Meshy, or with hermes config set MESHY_API_KEY.
  • Name the target first (Godot, Unity, a slicer, a web viewer) so the skill picks the output format before it spends credits.
  • Ask for the cost before each paid step and download the models you want to keep into a project folder.

What to expect

Textured, rigged or print-ready 3D models made from a sentence or a photo, without leaving your agent.

Copy this: Install + first ask

# Official source: hermes-agent.nousresearch.com/docs/plugins/meshy
# Needs Hermes >= 0.22.3, Node.js 18+ (npx) and a Meshy API key (Pro plan or above).
hermes plugins install meshy

Ask Hermes:
Make a low-poly treasure chest for Godot. Tell me the credit cost before you start.

Or:
Turn ~/photos/mug.jpg into a 3D model and get it ready to print at 10 cm.
