MCP server

Run Atlas tasks from Claude and other MCP clients by signing in, with no API key.

World Labs hosts a Model Context Protocol server, so an assistant can run Atlas tasks for you from a chat. You sign in with your World Labs account; there is no API key to create or paste.

1https://api.atlas.worldlabs.ai/mcp

Tasks run in a project you choose and use that project's Developer API credits, at the same prices as the API. See Billing.

Connect

Add the URL above as a remote MCP server in your client, then sign in when it opens World Labs in your browser.

Claude on the web or desktop: open Settings > Connectors, add a custom connector, and paste the URL.
Claude Code: run claude mcp add --transport http worldlabs https://api.atlas.worldlabs.ai/mcp, then run /mcp and sign in.
Other clients: any client that supports remote MCP servers with OAuth sign-in connects with the same URL.

Tools

Tool	What it does
`list_projects`	Lists the projects you can use and the task tools each can run.
`import_image`	Copies an image at an HTTPS URL into a project: a public image, or a file you attached where the client can pass it.
`create_image_upload`	Returns a signed upload URL for a local JPEG, PNG, or WebP file of up to 50 MiB.
A tool per task	Starts the task of the same name: `atlasTextToImage`, `images2PosedRGBD`, `atlasGenerate`, `atlasChisel`, `posedImages2Splats`, or `splats2Mesh`.
`get_operation`	Reads an operation, waiting up to 20 seconds for it to finish.
`get_asset`	Returns a fresh download link for an asset.

A task tool takes project_id, idempotency_key, and request. request is the task's request body, as its page in the API reference describes it, and the tool's schema carries the same fields. Calling a tool again with the same idempotency_key and request returns the original operation and does not start or bill a second run.

Media

A request names media as {"assetId": "..."} for an asset in the project, or as {"url": "..."} for a public HTTPS file. A task's outputs are assets too, so one task's output is the next task's input by its assetId.

Uploads through these tools are images only. An assistant in a chat usually cannot send the bytes of a file you attached, so give it a public image URL to import. An assistant with a shell, such as Claude Code, can upload a local file with create_image_upload and an HTTP PUT.

Results

A task tool returns an operation at once. The assistant polls get_operation until done is true, then reads the outputs and their download links from response. Links expire; get_asset returns a new one. See Operations for the operation fields and how long results are kept.
