Trident (Tripo 3D)

trident-mcp

An unofficial MCP server for the Tripo 3D API that covers every documented, deployed v3 workflow. A few endpoints are deliberately left out; they are listed in docs/MCP_TOOLS.md. Agents can:

• generate meshes from text, one image or several views;
• make reference images and multiview sets;
• texture, retopologize, UV-unwrap, segment, rig, animate and convert meshes;
• produce Gaussian splats.

The outputs land as files on disk. It ships as one Go binary over stdio, plus a Claude Code plugin with a workflow skill.

Quick start

Claude Code. Put the binary on your PATH, then install the plugin:

go install github.com/mordor-forge/trident-mcp/cmd/trident-mcp@latest   # or grab a release archive

/plugin marketplace add mordor-forge/claude-plugins
/plugin install trident@mordor-forge

The plugin asks for your Tripo key and output folder, and adds the tripo-3d skill. Then ask for what you want, e.g. "make a game-ready low-poly treasure chest and export it as FBX".

Any MCP client:

{
  "mcpServers": {
    "trident": {
      "command": "trident-mcp",
      "env": { "TRIPO_API_KEY": "tsk_...", "MODEL_OUTPUT_DIR": "/abs/path/generated_models" }
    }
  }
}

How it works

1. A task-creating tool (text_to_model, rig_model, convert_model, …) validates its arguments locally, uploads any local files, and returns a task_id.
2. wait_for_task waits with progress notifications, then saves the outputs to <output dir>/<task_id>/. For example: model.glb, rendered_image.webp, generated_image.png, front_view.png.
3. Pass a task_id as the next tool's input to chain steps: image → mesh → rig → animation → FBX.

Arguments use Tripo's own field names, so Tripo's docs apply to them directly. A few convenience fields differ from Tripo's wire format, such as multiview inputs given as a {front, left, back, right} map. See docs/MCP_TOOLS.md for all 28 tools.
