MCP server

Use Simi from Claude, Cursor, and other MCP clients.

Simi ships a remote MCP server over streamable HTTP, named lamina-simi. It lets an agent start a video, check on it, and hand back the finished file without leaving the conversation.

Endpoint

text

https://api.laminalabs.ai/mcp

Claude Code

bash

claude mcp add --transport http simi https://api.laminalabs.ai/mcp

Generic client configuration

json

{
  "mcpServers": {
    "simi": {
      "type": "http",
      "url": "https://api.laminalabs.ai/mcp"
    }
  }
}

Authentication uses OAuth: an unauthenticated client gets a 401 with the details it needs, then opens a browser window to sign in to your Simi account on first use.

Tools

simi_submit_video — start a video from a prompt. Optional duration_minutes (1–5, default 1), aspect_ratio (16:9, 9:16, 1:1), and language. Returns a job id immediately.
simi_get_video — check a job by job_id and get playback URLs once it is ready.
simi_list_videos — review recent jobs, up to limit (default 10).
simi_cancel_video — stop a job that is still running and release its reserved credits.

Rendering runs in the background and usually takes two to five minutes. Clients that hold the SSE stream open get progress notifications pushed to them; otherwise poll simi_get_video no more than once every 30 seconds.

Document grounding is not available over MCP yet — tools take a prompt only. Upload a document through the API or the app instead.
