Assets

upload_asset_from_url

Ingest an image asset directly from a public https URL. The URL must be reachable without authentication, must resolve to a public IP (SSRF guards enforced), and must not be a chat attachment URL. Sentway dedupes by content hash; if the same bytes already exist in this account, `dedupe` is true and no new storage is written. Optional name/description/tags apply the same caps as update_asset_metadata.

Behaviour

Effect: Write. It creates or updates data in the account.
Repeat calls: Not idempotent. Repeating the call can produce a further change.
Plan: Available on every plan, including free.

Parameters

Name	Type	Required
url	string	Yes
name	string	No
description	string	No
tags	array of string	No

Returns

Name	Type
asset	object
dedupe	boolean
idempotency_replay	false

Using it

upload_asset_from_url is called by an AI assistant connected to Sentway over MCP, not by hand. Point the assistant at the Sentway MCP endpoint and complete the OAuth flow, and the tool becomes available in the same session as the other 38 Sentway tools. See connecting over MCP.
