Your agent writes the code. Now it ships the marketing.

• Pick the right film: browse the film library with list_films and read any film's contract with describe_film before it renders.
• Make a video: motion graphics for a launch, a feature or a changelog, in your colors, type and logo. 25 credits, or 50 for a platinum video.
• Make a still: one painted image from your prompt and Brand DNA, sized for the channel. 10 credits.
• Write the caption for each platform.
• Post now with post_run, or queue it with schedule_post at a time and timezone you pick.
• Make it for any brand: pass a brand to create_campaign or render_asset for a client or side project, with nothing from your own workspace leaking in.
• Read and update your Brand DNA, and upload product screenshots the next render can use.

If you build with an agent, your product lives in the editor. Marketing lives somewhere else: a design tool, a scheduler, a tab you forget to open. So the feature ships and nobody hears about it.

With Siren on MCP the ask is one line in the same chat: post this. The agent already knows what you just shipped. Siren already knows what your brand looks like. The post goes out and you go back to building.

• Posting is off until you flip Allow posting.
• Posts only go to channels you connected yourself in the Siren dashboard.
• Every render is saved in your Siren workspace, so you can look before anything goes out.
• You can revoke the agent any time under Developers.
