trident-mcp is an AI-powered 3D model generation and post-processing server (Go-based, using Tripo as the backend) that lets you create, convert, and refine 3D models using text, images, or multi-angle views.
3D Model Generation:
text_to_3d — Generate a 3D model from a text prompt, with optional negative prompt, face limit, and model version selection.
image_to_3d — Generate a 3D model from a single reference image (local path or public URL), with options for orientation, texture quality, and face limit.
multiview_to_3d — Generate higher-quality 3D models from 2–4 reference images taken from different angles.
Task Management:
task_status — Poll the progress of any async generation or post-processing task (queued, running, success, or failed).
download_model — Download a completed 3D model to a local file.
Post-processing:
convert_format — Convert a model to a different file format: GLTF, FBX, OBJ, STL, USDZ, or 3MF.
retopologize — Create a low-poly version of a model with a target face count in quad or triangle mesh.
stylize — Apply a stylization effect: lego, voxel, voronoi, or minecraft.
Server Introspection:
list_models — List supported model versions and their capabilities.
get_config — View the active backend, output directory, and server version.
Provides tools for 3D model generation and post-processing, with companion skills designed to integrate with Blender for automated 3D modeling workflows.
Supports automated testing and release processes through GitHub Actions, including unit checks on pushes/pull requests and E2E smoke tests on main branches and version tags.
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.
Build locally:
go build -o ./trident-mcp ./cmd/trident-mcpRun with a Tripo key:
TRIPO_API_KEY=tsk_your_key_here ./trident-mcpOne-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=1Related MCP server: instant-meshes-mcp

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.
