media.request_upload

Validate an upload (mime/size by kind) and return the deterministic, tenant-namespaced provider_key. No bytes: the connector mints the signed URL from the key.

• Scope: media.write
• System: no
• Reachable from: POST /v1/commands/media.request_upload (tenant credential) · MCP tool media.request_upload · SDK client.call('media.request_upload', …)
• Events: none — It writes NOTHING: it validates mime/size and NAMES the deterministic provider_key that the connector then signs. A command that changes no state has nothing to announce.
