SpAItial Ships Claude Plugin and Hosted MCP Server for Gaussian Splatting Worlds
Michael Rubloff
SpAItial has released a Claude plugin and a hosted MCP server that let you generate, edit, and export explorable gaussian splatting worlds from inside a chat, turning the company's Echo world model from something you reach through a REST API or web app into something you drive conversationally across any agent that speaks the Model Context Protocol. A single text prompt, an image, or a 360° panorama goes in. A navigable Gaussian splat you can orbit, pan, and zoom comes back, delivered as a hosted URL that opens in any browser with no download or local setup.
The plugin bundles four skills that cover the full lifecycle. Create-world generates a world from a prompt, image, or panorama. Edit-world runs SpAItial's panorama edit loop, where edit_panorama returns a pano_ artifact you can inspect and iterate on before create_world turns the accepted edit into a new world.
Manage-worlds lists past generations, checks job status, renames, sets visibility (private, public, or listed), or cancels a running job and export-mesh converts a finished world into a downloadable .ply mesh, either full-resolution or simplified for real-time use. The plugin talks to SpAItial through the hosted SpAItial MCP server at mcp.spaitial.ai/mcp, a stateless, streamable-HTTP server whose tools map onto the Developer API.
An agent can prompt, generate, poll, and download a splat or mesh entirely on its own. Generation runs roughly five to ten minutes on Echo 2 - Standard, so the tools are built to be polled via get_world_status rather than blocked on, and download URLs are short-lived signed links resolved just before fetching.
Because the connection is native remote MCP rather than a local process, the same endpoint works across Claude Code, Claude Desktop, Cursor, VS Code, Codex, and opencode and inside sandboxed environments such as Cowork without any network workaround.
SpAItial launched in 2025 with $13M in seed funding and a thesis built on spatial foundation models, then unveiled Echo, which turns a single image or text prompt into a metric-scale scene rendered as Gaussian splats, and followed it with Echo-2, which added segmentation driven object level editing and virtual staging workflows. Until now that model lived behind the REST API or the web app. The plugin and MCP server move world generation, the panorama edit loop, library management, and mesh export directly into the agent surfaces developers and technical artists already work in.
It is available now, with setup and the full tool list documented for every client at the SpAItial MCP server docs.
