Siren MCP

Your agent makes the images, captions, and videos for your brand, then posts them to your socials. You show Siren the brand once. After that you type post this in Cursor, Claude, ChatGPT, Codex, or Grok and it goes out.

Remote MCP server, Streamable HTTP, OAuth 2.1. No API keys to copy.


Server	`https://mcp.mysiren.ai/mcp`
Registry	`ai.mysiren/siren`
Docs	https://mysiren.ai/docs/mcp
Plans	One video is $9.99 once; plans start at $19 a month. MCP and videos are on every plan; credits are the only meter.

Connect

Claude Code

claude mcp add --transport http siren https://mcp.mysiren.ai/mcp

Claude (claude.ai): Settings → Connectors → Custom → https://mcp.mysiren.ai/mcp

Cursor: Settings → Tools & MCP → add a remote server, or in ~/.cursor/mcp.json:

json

{ "mcpServers": { "siren": { "url": "https://mcp.mysiren.ai/mcp" } } }

ChatGPT: Developer Mode on → Settings → Apps & Connectors → Create → https://mcp.mysiren.ai/mcp

Grok: grok.com/connectors → Custom, or grok mcp add --transport http siren https://mcp.mysiren.ai/mcp

The agent opens a consent page on app.mysiren.ai. Approve once. Posting stays off until you turn on Allow posting on that screen. Revoke any time under Developers.

Tools

Tool	What it does
`get_account`	Workspace, plan, credits, connected channels
`clarify_brief`	Turns a one-line ask into a brief Siren can render
`create_campaign`	Generates the asset. Optional `scheduled_at`, `timezone`, `platforms`
`render_asset`	Renders a specific output type
`list_runs`, `get_run`	Status and result URLs
`post_run`	Publishes a finished run to your connected channels now
`schedule_post`	Queues a finished run for a time in your timezone
`get_brand_dna`, `update_brand_dna`	Read and patch the brand profile
`list_product_screens`, `upload_product_screen`, `update_product_screen`, `delete_product_screen`	Product screenshots Siren can paint into assets
`studio_templates`	The 33 Studio data-card types, families, and body fields
`studio_card`	Render a Studio card. Optional live post
`studio_automate`	Create a Studio profile; returns generate curl and hook URLs
`studio_schedule`	Render a Studio card and queue a scheduled post

Posts go through the channels already connected in the Siren dashboard: X, LinkedIn, TikTok and YouTube (Instagram once Meta approves the app). The agent never sees your platform tokens.

Example

> Post an update about the new export feature. Use the dashboard screenshot.

The agent calls clarify_brief, then create_campaign, waits on get_run, and calls post_run. One image or film, a caption, and the post, on brand every time.
