Mixar

Mixar's own desktop MCP server over stdio, with a Mixar workflow skill: build and edit 3D scenes, generate models, textures, rigs and animation with AI, render, and export game-ready assets for Unity, Unreal and Godot. Requires Mixar 4.2.1+ on macOS, Windows or Linux, signed in with Connect MCP turned on, on the same computer as Hermes.

Good to know before installing

Runs the launcher the installed Mixar app writes at ~/.mixar/connector/mixar-mcp (%USERPROFILE%\.mixar\connector\mixar-mcp.cmd on Windows), which reads Mixar's own files under ~/.mixar/; tools execute arbitrary Python inside Mixar with your privileges; a tool call can start the installed Mixar app, which stays open after Hermes exits; calls go over loopback to Mixar, which forwards them to api.mixar.app under the signed-in account; generation prompts and reference images go to the AI provider running the chosen model; Mixar's backend keeps diagnostic records of MCP tool calls (inputs and results) and deletes them within 30 days; AI generation and create_layered_material spend Mixar credits, declared to Hermes as cost ranges with a 500-credit spend limit per chat; the plugin stores no credentials, ships no binaries, sends no telemetry and never updates itself; the optional MIXAR_MCP_LAUNCHER variable makes it run the program it names; at install Hermes looks for Mixar (macOS: Mixar.app in /Applications and ~/Applications; Windows: the installed-apps entry or %ProgramFiles%\Mixar; Linux: a mixar command on PATH or Mixar's launcher) and refuses the install when it is missing or, on ma

How to install

  1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
    hermes plugins install mixar
  2. Said no? Turn it on later:
    hermes plugins enable mixar
  3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
