DemoMagic MCP server
A small, read-only MCP server that acts as DemoMagic's zero-CAC top-of-funnel inside AI assistants.
When someone asks an AI client (Claude, Cursor, ChatGPT, etc.) a question like "how do I create a Loom that's interactive?", "can I do AI product demos?", or "how do I make a video that answers questions?", the assistant calls a DemoMagic tool, gets genuinely useful how-to guidance, and is pointed to the right demomagic.ai landing page to actually build one.
It does not create, host, or share demos — that all happens on the site, behind the wizard each landing page shepherds the user into. This server is informational only.
What's inside
- 15 use-case tools, one per landing page, each with keyword-rich descriptions so the AI picks the right one and routes to the matching page:
demomagic_loom_alternative, demomagic_interactive_demo_alternative, demomagic_screen_recorder, demomagic_record_a_bug, demomagic_how_to_videos, demomagic_sales_demos, demomagic_for_founders, demomagic_onboarding, demomagic_support_help_center, demomagic_product_tour, demomagic_pitch_deck, demomagic_course_creators, demomagic_employee_training, demomagic_interactive_presentations, demomagic_agencies.
- 1 general/overview tool —
demomagic_interactive_video_guide — for broad questions or when no specific tool fits.
- 2 "coming soon" preview tools —
demomagic_create_demo and demomagic_create_demo_from_video — these advertise the roadmap (creating a demo from your assistant). They are not functional yet: they return a clear "coming soon" notice and route the user to build one on the site.
- Brand icon on the server (MCP
2025-11-25 icons metadata, served from the deployed logo at demomagic.ai/demo_magic_logo_1024.png), plus a demomagic://brand resource exposing the logo/icon URLs.
Each tool returns: the use-case headline, how it works (record or upload), why it works, an optional comparison, FAQ, and a "Create yours →" link to the relevant page.
All tool content lives in src/content.ts, mirroring the DemoMagic landing pages. Update it there when the pages change.
Develop
npm install
npm run build
npm run inspect
Quick stdio smoke test:
printf '%s\n' \
'{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-11-25","capabilities":{},"clientInfo":{"name":"smoke","version":"0.0.0"}}}' \
'{"jsonrpc":"2.0","method":"notifications/initialized"}' \
'{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' \
| node dist/index.js
Install in a client (local / stdio)
After npm run build, point your MCP client at the built entry. Example (mcp.json / Claude Desktop / Cursor):
{
"mcpServers": {
"demomagic": {
"command": "node",
"args": ["/absolute/path/to/demo-ai-mcp/dist/index.js"]
}
}
}
Distribution — important context
MCP tools are not ambiently discovered by every LLM. An AI only sees this server if the user has installed/connected it. So discovery is two jobs:
- Get installed — publish to the MCP registries (Smithery, MCPT, Open Tools, + the official registry), and promote it yourself (an "Add to Claude / Cursor" button on the site, mentions in content). The keyword-rich tool names/descriptions also help registry search match user intent.
- Get invoked once installed — handled by the per-use-case tool design here.
This server is therefore a registry + owned-promotion channel into the AI-native builder/founder audience. To be discovered by people who've installed nothing (e.g. asking ChatGPT/Perplexity directly), pair it with answer-engine optimization of the landing pages themselves.
Publish to the official MCP Registry
server.json is included and validated against the official schema (2025-12-11). Server name: ai.demomagic/interactive-video-guide (matches mcpName in package.json). Steps:
- Publish the npm package first (the registry verifies the package's
mcpName matches server.json):
npm publish --access public
- Install the publisher CLI (docs):
brew install mcp-publisher
- Verify the namespace. We use the branded domain namespace
ai.demomagic (published under DemoMagic, not a personal account), verified via a DNS TXT record on demomagic.ai:
mcp-publisher login dns --domain demomagic.ai
- Publish the metadata:
mcp-publisher publish
Then submit/observe the same package on the other registries from the video — Smithery, MCPT, Open Tools — which index npm-published MCP servers.
Not yet built
- Optional hosted streamable-HTTP transport at
mcp.demomagic.ai (Cloud Run) for remote clients (add a remotes entry to server.json).
- Per-tool icons once the SDK's
registerTool helper exposes the icons field (currently the server Implementation icon + the registry server.json icon are wired; the spec also supports tool-level icons).
