trident-mcp

trident-mcp is a Go MCP server for AI-assisted 3D model generation and post-processing.

The server is client-agnostic and works independently with any MCP-compatible client. You do not need any companion skills or extra MCP servers to use the core 3D generation, polling, download, and post-processing tools.

It currently ships with a Tripo-backed provider and exposes tools for:

• text-to-3D generation
• image-to-3D generation
• multiview-to-3D generation
• async task polling
• model download
• retopology
• format conversion
• stylization
• model catalog and server config inspection

Requirements

• Go 1.25+
• A Tripo API key in TRIPO_API_KEY

Install

Build locally:

go build ./cmd/trident-mcp

Or install with Go:

go install github.com/mordor-forge/trident-mcp/cmd/trident-mcp@latest

Configuration

The server reads configuration from environment variables:

| Variable | Required | Default | Description | | --- | --- | --- | --- | | TRIPO_API_KEY | Yes | none | Tripo API key used for generation and editing calls | | MODEL_OUTPUT_DIR | No | ~/generated_models | Directory where downloaded models are written |

Running

The server speaks MCP over stdio:

TRIPO_API_KEY=tsk_your_key_here trident-mcp

Example MCP client configuration:

{
  "mcpServers": {
    "trident-mcp": {
      "command": "trident-mcp",
      "env": {
        "TRIPO_API_KEY": "tsk_your_key_here",
        "MODEL_OUTPUT_DIR": "/absolute/path/to/generated_models"
      }
    }
  }
}

Tools

Generation

• text_to_3d
• image_to_3d
• multiview_to_3d

These tools start asynchronous tasks. Use task_status to poll for completion, then download_model to retrieve the task output.

Status and Download

• task_status
• download_model

download_model saves the task's actual output format. If you need a different format, run convert_format first and then download the conversion task.

Post-processing

• retopologize
• convert_format
• stylize

Introspection

• list_models
• get_config

get_config reports the active backend, output directory, and server version.

Skills

The repo also includes companion agent skills under skills/:

• skills/3d-gen/SKILL.md
• skills/multiview-3d/SKILL.md
• skills/3d-to-blender/SKILL.md

These skills are optional. The MCP server itself works fine on its own in any MCP client.

Some of the companion skills are designed to compose trident-mcp with gemini-media-mcp for a fuller automated pipeline. In that setup, gemini-media-mcp can help with ideation, reference image generation, and multi-angle image creation, while trident-mcp handles reconstruction and post-processing. That pairing enables a more complete flow from idea to finished 3D model.

Development

Run the local checks:

go test ./...
go vet ./...

There is also an opt-in E2E smoke test for live Tripo uploads:

TRIPO_API_KEY=tsk_your_key_here go test -tags=e2e -run "TestE2E_" ./internal/provider/tripo/ -v

Release

GitHub Actions runs unit checks on pushes and pull requests, and runs the E2E smoke test on main and version tags. Tagged releases are built with GoReleaser.

Artifacts are stamped with the release version so the binary and MCP implementation metadata stay aligned.
