How does SnapStack actually work?
A browser extension captures the current tab and sends the screenshot to a small local server running on 127.0.0.1. The server holds the stack and exposes it over MCP so your LLM can retrieve the images on demand.

SnapStack is a local browser extension and bundled MCP server that lets you capture any browser tab in one click and stack the screenshot locally. Your AI assistant can then read those screenshots on demand over the Model Context Protocol, without copy-pasting images. It is designed for users of MCP‑capable clients like Claude Code.
Install both the browser extension and the always‑on local server (both install in a couple of minutes). Click the extension to capture a tab; the screenshot is stacked on your local machine. Then ask your LLM to “look at my screenshots” and it picks them up via MCP.

Yes. Captures go only to the local server on your own machine. Nothing is uploaded to any external service, and there is no account or telemetry.
No. SnapStack requires no account registration or login.
Any MCP‑capable client, including Claude Code and others that support the Model Context Protocol.
On your own machine, in the stack managed by the local server (127.0.0.1). No data leaves your computer.
