SimSense MCP Connector Gives Claude Artifacts Permanent URLs with Persistent State
SimSense is an MCP connector that solves a specific problem with Claude-generated artifacts: when Claude creates HTML, JavaScript, or interactive tools, they typically disappear once you close the chat window. This connector gives those outputs permanent addresses on the web.
What SimSense Does
The tool creates "sims" - living HTML pages deployed to permanent URLs that exist on the open web. These sims can be opened on any device with a browser, displayed on TVs, iPads, or kiosks, and shared via Slack or WhatsApp as simple URLs.
Key Features from the Source
- Screen persistence: Sims can lock screens awake (no sleep, no timeout), transforming displays into ambient information infrastructure for spaces like kitchen counters, lobby walls, or break room TVs.
- State memory: Sims can read and write persistent state, allowing data to persist between visits. This enables actual applications rather than static displays.
Example Use Cases
The source provides several working examples of sims with persistent state:
- A shoutout board where submissions persist:
https://sim-ghost-sun-2716.my.simsense.ai - A community job board for a Vermont town:
https://sim-liminal-feed-3116.my.simsense.ai - An AI layoff tracker anyone can contribute to:
https://sim-cold-shell-9435.my.simsense.ai - Generative art that runs indefinitely on a screen:
https://sim-idle-span-8820.my.simsense.ai
How It Changes Claude's Capabilities
According to the source, state memory transforms Claude from a generator into a builder of actual applications. This enables:
- Polls that persist over time
- Forms that collect and store submissions
- Leaderboards that update
- Trackers that accumulate data
The tool is available as an MCP connector for Claude Pro, Max, and Team users. It's free during beta and accessible at simsense.ai.
Who It's For
Claude users who want to deploy Claude-generated HTML/JS artifacts to permanent, shareable URLs with persistent state functionality.
