An AI video generator your agent can call

Siren is an AI video generator your agent can call over MCP. Send a brief from Claude, Cursor or ChatGPT and get a finished motion-graphics film in your brand, ready to post.

Most AI video tools are a web app you have to open. Siren is also an MCP server. Your agent sends a brief, Siren renders a finished film in your colors, type and logo, and it can post it too.

How the film is made

Siren films are motion graphics, not generated footage. Each film is a scene system written in code and rendered frame by frame with your brand. The same brief gives the same film.

Music and sound effects come with every film. Voiceover is added only when your brief asks for it.

Generated footage vs a rendered film

Text-to-video models make footage that changes every run. That is fine for b-roll and hard for a brand. Siren renders the same brand system every time, so the tenth film looks like the first.
