Connect an AI assistant

Ask Claude, ChatGPT, Claude Code or Cursor to make demo videos for you.

Demosmith runs an MCP server, so an AI assistant can check a task, create a demo, follow it and hand you the video link, all from a conversation.

MCP server URL

https://mcp.demosmith.ai/mcp

Assistants that support sign-in (Claude, ChatGPT, Claude Code) ask you to sign in to Demosmith and allow access. Tools without sign-in (Cursor) use an API key. Either way, demos are created in your organization and use your plan’s minutes.

Claude

1. In Claude, open Customize → Connectors, choose Add, then Add custom connector.
2. Name it Demosmith and paste the MCP server URL.
3. Select Connect, sign in to Demosmith, and allow access.

On a Claude Team or Enterprise plan, only an organization owner can add a custom connector.

ChatGPT

1. In ChatGPT, open Plugins, choose Add, then Add custom MCP server.
2. Name it Demosmith, paste the MCP server URL and keep OAuth. For the icon, upload the Demosmith icon.
3. Create it, sign in to Demosmith when asked, and allow access.

Then pick Demosmith in a chat (type @Demosmith) and ask for a demo.

Claude Code

Add the server, then type /mcp in Claude Code to sign in:

claude mcp add --transport http demosmith https://mcp.demosmith.ai/mcp

Or use an API key instead of signing in:

claude mcp add --transport http demosmith https://mcp.demosmith.ai/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

Cursor

Add this to ~/.cursor/mcp.json, with an API key from the Developers page:

{
  "mcpServers": {
    "demosmith": {
      "url": "https://mcp.demosmith.ai/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

​

Try it

Ask something like:

Make a Demosmith demo of https://cal.com showing how to book a 30-minute meeting.

The assistant checks the task first, confirms the details with you, creates the demo and checks back until the video is ready. A demo keeps going even if you close the conversation; ask about it later and the assistant picks it up.

​

What the assistant can do

Tool	What it does
list_demo_options	Languages, voices, tones, music and resolutions
check_demo_prompt	Check a task before creating a demo (free)
create_demo	Create and start a demo
get_demo_status	Where a demo is, and when to check again
answer_demo_question	Answer a question the agent asked
get_demo	A finished demo, with its video links
list_demos	Your demos, newest first
cancel_demo	Cancel a demo

​

Logins stay out of the chat

An assistant never asks for, or accepts, a password or a verification code. If the agent reaches a sign-in page, the assistant gives you a secure link to the demo’s page in Demosmith, and you type the login there. The chat, and the assistant’s provider, never see it.
