The official Meshy plugin for Hermes: text and image to 3D models, the 200-credit chat cap, and what it sends to Meshy

What the official catalog entry says

These points come from plugin-catalog/meshy.yaml in the Hermes Agent repository (maintainer NousResearch, tier "official"), read 2026-10-22. The plugin's docs are in hermes-official-plugins.

• What it is. Meshy's own MCP server, pinned at @meshy-ai/[email protected], for text, image and multi-image to 3D, texturing, remeshing, rigging, animation, concept images and 3D-print preparation, with a bundled meshy-3d workflow skill.
• Requirements. Hermes 0.22.3 or later, Node.js 18 or later, and a MESHY_API_KEY.
• In Hermes Desktop. Inline 3D cards with a download and convert menu, a gallery of recent generations and saved models with a "Made from" history, image sets, and a credit chip in the status bar.
• Spending controls. Every credit-spending call goes through Hermes's approval prompt with its estimated cost, and a 200-credit limit per chat makes it ask again.
• Data and downloads. The first start downloads the pinned server from npm through npx. Prompts and the images or models you or the agent name are sent to Meshy's API (api.meshy.ai) under your key; only MESHY_API_KEY is taken from your profile; no analytics are sent, and the user agent names Hermes and its version. Downloads never overwrite an existing file.

What the video adds, not confirmed by the catalog

• 28 tools in groups: six that create (text to 3D, image to 3D, many images to 3D, text to image, image to image, refine), five that edit (remesh, retexture, convert format, resize, UV unwrap), four for characters (rig, animate, text to character, ready-made moves), seven for 3D printing, and the rest for checking jobs.
• About 19,000 tokens to describe all 28 tools, loaded only when Hermes uses one, so they cost nothing in an ordinary chat.
• 5 to 62 credits per call for paid tools, and Meshy's hosted files disappear after three days, so save what you want to keep.
• File types for a finished model: GLB, FBX, OBJ, STL and USDZ, already made; a convert button costs credits if you need another.
• Printing tools that check printability, fix weak spots, export multi-colour 3MF, split large models into parts and hand off to a slicer, which he says it can detect.
• Why a skill. He says the Meshy server's own rules (state the cost before spending, don't restart a job you are unsure about) are not passed to the model by Hermes, so the plugin puts them in the bundled skill.

Gotchas & Caveats

• Credits cost money, and the 200-credit prompt is a prompt, not a hard stop: read the estimate before approving.
• Everything you ask for, including photos, goes to a third party. Don't send images you wouldn't upload to Meshy directly.
• We have not run the plugin, and the video does not show it generating a model, so quality and print results are untested here.
• The tool count, token figure, per-call credits and three-day expiry are the video's numbers; check Meshy's pricing and your account before relying on them.

Key Takeaways

• Install needs Hermes 0.22.3+, Node.js 18+ and a Meshy API key.
• Spending is gated by an approval prompt with a cost estimate and a 200-credit per-chat limit.
• Download what you want to keep: the video says hosted files expire after three days.
