Request Data Source Upload

Creates a short-lived presigned S3 PUT URL for a .tds or .tdsx file. Upload the raw bytes using the returned requiredHeaders before expiresAt, then pass datasourceUploadId to Publish Data Source. Requesting a URL does not publish anything to Tableau.

Requires MCP_S3_BUCKET and Explorer (Can Publish) or higher. The MCP scope is tableau:mcp:datasource:create; requesting a URL does not call the Tableau REST API.

Use OAuth or server-side authentication. This tool is not available when the caller is authenticated via Passthrough auth.

Arguments

fileName: filename ending in .tds or .tdsx.

Example result

{
  "datasourceUploadId": "123e4567-e89b-42d3-a456-426614174000",
  "uploadUrl": "https://s3.example.com/signed-put",
  "expiresAt": "2026-10-14T18:05:00.000Z",
  "maxSizeBytes": 5000000000,
  "requiredHeaders": {
    "Content-Type": "application/octet-stream"
  }
}

The content type is application/xml for TDS and application/octet-stream for TDSX. Staged publishing retains the advertised 5 GB (5000000000 bytes) limit. The signed URL does not constrain the PUT size; oversized staged objects are rejected before uploading to Tableau. Configure S3 lifecycle rules for staged-file expiry. Publishing buffers the file in server memory; see Data source publishing.
