# Hermes Agent gets an official Meshy 3D plugin

> Nous Research shipped an official Hermes plugin that calls Meshy’s MCP server to generate 3D models and preview models in Hermes Desktop chat.

Nous Research’s official plugin catalog now lists a Meshy plugin for Hermes Agent. On October 22, 2026, Nous Research posted that you can ask Hermes to make a treasure chest for Godot, or turn a photo of a mug into a model you can print, and that the job runs through Meshy’s MCP server. In Hermes Desktop, the post says, the models render in chat.

The plugin page describes a portable Agent Plugins v1 package in Hermes Official Plugins. It launches Meshy’s first-party MCP server as `npx -y @meshy-ai/meshy-mcp-server@0.6.4` over stdio for every new session while the plugin is enabled. The docs say that package was published October 13, 2026, that `@latest` is deliberately not used, and that no `mcp_servers` edit in `config.yaml` is required. A bundled `meshy-3d` skill carries the server’s routing rules, including cost confirmation, because Hermes does not pass MCP server instructions to the model.

Install is `hermes plugins install meshy`, then `hermes plugins enable meshy`. It needs `MESHY_API_KEY` and Node.js 18+ with `npx` on PATH. In Hermes Desktop, set the key under Settings, Plugins, Meshy; the running server restarts with the new key. Without Desktop, `hermes config set MESHY_API_KEY` writes the profile `.env`. API keys need a Meshy Pro plan or above.

The catalog says every credit-spending call goes through Hermes’s approval prompt with an estimated cost, and a 200-credit limit per chat makes it ask again. Most Meshy tools spend 5–62 credits per call. The server is marked `trust: untrusted`, so Hermes asks before every write-capable call — creates, downloads, and cancels — with Allow once, Allow for this session, or Deny. Read-only tools run without a prompt. Unattended runs, including cron, `hermes chat -q`, and a gateway with no approver, cannot approve, so paid calls are refused.

On Hermes builds with MCP tool costs, the plugin declares each tool’s price and that 200-credit limit. The approval prompt then reads "Costs about 5–25 credits" plus what the chat has spent. Once a chat would pass the limit, Hermes asks again even if those prompts were skipped by a `config.yaml` override. Older Hermes builds ignore the declaration.

Desktop preview is opt-in. Turn the Desktop switch on under Capabilities, Plugins, and Hermes Desktop uses stock three.js for inline 3D cards, a download menu for formats already produced (no extra credits), a gallery with a "Made from" history, and a status-bar credit chip. Other clients show the card line as text. Meshy publishes the server only as a local stdio package and offers no hosted MCP endpoint.

Read the Meshy plugin page, then install it from the catalog and add a Pro-plan API key. Expect the approval prompt on the first paid call, and watch the 200-credit limit for that chat.
