`upload_asset`

Upload media (image or video) to SocialClaw hosted storage. Provide either sourceUrl (a public URL the server downloads) or contentBase64. Returns an asset id and a public URL usable as media_link in schedules.

Calling it

Invoke this tool with a JSON-RPC 2.0 tools/call request against the hosted MCP endpoint at POST https://getsocialclaw.com/mcp. Send your workspace API key as Authorization: Bearer sc_live_your_key. In an MCP client (Claude, Cursor, Claude Code) the client makes this call for you — just ask it to use upload_asset.

Arguments

`filename`	`string`	required	Filename including extension, e.g. launch.png.
`sourceUrl`	`string`	optional	Public URL to download the media from.
`contentBase64`	`string`	optional	Base64-encoded file content (alternative to sourceUrl).
