Connect Cursor to After Effects

Cursor adds a remote MCP server through its mcp.json. One entry with the address; the sign-in happens in your browser the first time Cursor calls it.

Install the Prism panel
Done in step 1 and step 2.
Sign in from the panel
Done in step 3.
3
Add the server

Open Cursor Settings, Tools & MCP, New MCP Server, which opens mcp.json. Use ~/.cursor/mcp.json for every project, or .cursor/mcp.json inside one project.

{
  "mcpServers": {
    "prism": {
      "url": "https://live.oneprism.io/after-effects"
    }
  }
}
4
Approve it in your browser
Cursor starts the sign-in on the first call and stores the credential. Approve it when the browser opens.
5
Open a composition and confirm the loop
Prism acts on whatever composition is open. Ask: "Tell me about my current composition."

If the client was already open, quit it and open it again

Save the address, then run the client's sign-in step. If your AI client was open before the address existed and does not show Prism, quit it and open it again: most clients load their connections at launch. Then open a composition and ask for it by name.

Design

Claude Design uses the connectors of your Claude account. Add the Prism address once, approve it in your browser, and Claude Design can build in your open comp.

Gemini

The Gemini app has no MCP client. Connect Gemini to your live After Effects project through Google Antigravity: one serverUrl entry, one browser sign-in.
