# Siren MCP [](https://mcpservers.org/servers/hexahedral-inc/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.

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. ## This repo Listing and connect docs. The server is hosted at mcp.mysiren.ai. Questions: open an issue or write to hello@mysiren.ai.
