Example questions

Try asking your AI client

  • Which files are still in Temp Storage right now?

  • Did the PDF I saved from Gmail yesterday ever get a shareable link?

  • Find the file_id for the invoice I stored a couple of days ago.

  • Write a short list of files that expire in the next 6 hours - do not delete them yet.

  • Which uploads are large enough that I should move them before they expire?

Overview

Private ephemeral file storage for AI workflows. Store files between tool calls, read them via MCP, share via presigned links, or pass file_id to other integrations (Email, Gmail, WordPress).

Prerequisites

  • A stackgate.ai account
  • Temp Storage enabled on your hub (platform administrator configures object storage)

Getting credentials

  1. Open Integrations → Temp Storage.
  2. Click Activate — no upstream account or API key is required.
  3. Your company admin may need to allow Temp Storage on Company Integrations.

Using with AI clients

  • Dedicated endpoint: POST /mcp/temp-storage
  • Private gateway: temp-storage__* tools

Standalone workflow: create_file → read_file or create_temp_link → delete_file.

Cross-tool workflow: email__download_attachment or gmail__download_attachment with store_in_temp_storage=true, or drive__download_file with mode=temp-storage → returns file_id → wordpress__upload_media with file_id.

Always pass file_id between tools — never bucket paths.

Troubleshooting

  • 503 not configured — hub administrator must configure Temp Storage object storage.
  • 422 not activated — activate Temp Storage on My Integrations.
  • 429 quota exceeded — daily hub limits apply; retry after UTC midnight.
  • File expired — files auto-delete after ttl_hours (default 2, max 24); store again if needed.
  • File too large — default max 50 MB per file.

Available tools

  • create_file

    Store a private file in Temp Storage. Returns file_id for cross-tool handoff.

  • read_file

    Read a stored file by file_id. Returns embedded binary under 10 MB or a resource_link for larger files.

  • create_temp_link

    Create a presigned download URL for a stored file. Link expires independently of the MCP session.

  • delete_file

    Delete a stored file before its expiry time.

MCP endpoint: https://stackgate.ai/mcp/temp-storage (HTTP) or via the private gateway.
