trident-mcp

trident-mcp is a Go MCP server for AI-assisted 3D model generation and post-processing. It runs as a single stdio binary and currently uses the Tripo v3 API behind provider capability interfaces.

Quick Start

Build locally:

go build -o ./trident-mcp ./cmd/trident-mcp

Run with a Tripo key:

TRIPO_API_KEY=tsk_your_key_here ./trident-mcp

One-command development bootstrap and smoke check:

go mod download && go install github.com/golangci/golangci-lint/cmd/golangci-lint@v2.11.4 && go test ./... -count=1

MODEL_OUTPUT_DIR	No	~/generated_models	Directory where downloaded models are written

Tool Overview

The server exposes tools for text/image/multiview 3D generation, image preparation, splats, async task polling, account balance and usage, file uploads, downloads, conversion, retopology, stylization, texture/refine/segment/complete workflows, rig checks, rigging, animation retargeting, and model/config inspection.

See docs/MCP_TOOLS.md for the full tool contract and known Tripo v3 quirks.

Development

The normal local gate is:

go build ./cmd/trident-mcp
go test ./... -count=1
go vet ./...
golangci-lint run
go run golang.org/x/vuln/cmd/govulncheck@latest ./...

Live E2E tests require TRIPO_API_KEY and can spend credits when opt-in generation flags are set. See docs/OPERATIONS.md.
