Snapstack Server
Run a local SnapStack intake server so browser captures flow into MCP tools on localhost.
Overview
SnapStack Server is an MCP server for the Idea phase that ingests browser captures locally and serves them to agents over 127.0.0.1 via stdio MCP.
What is this MCP server?
- Local always-on server pairing SnapStack browser extension with MCP on 127.0.0.1
- stdio MCP via npx snapstack-server with positional argument mcp
- Browser capture intake without sending screenshots to a third-party cloud by default
- Version 1.2.3 npm package from registry.npmjs.org
- Works alongside SnapStack extension documented on GitHub
- Server version 1.2.3
- stdio via npx snapstack-server with mcp positional argument
- Designed for MCP over 127.0.0.1 per server description
What problem does it solve?
You lose context from browsing because screenshots and page state never reach your agent in a structured, local pipeline.
Who is it for?
Solo builders who research in the browser daily and want localhost-only capture intake into Claude Code or Cursor.
Skip if: Teams needing centralized cloud screenshot archives or headless CI capture without the browser extension.
What do I get? / Deliverables
After install, SnapStack captures from the extension are available to MCP tools on your machine for research and prototyping prompts.
- MCP-accessible queue of browser captures from SnapStack
- Local-only capture pipeline paired with the extension
Recommended MCP Servers
Journey fit
Research and validation start with collecting visual and DOM context from the live web before you spec or prototype. Research subphase fits always-on capture from browsing sessions into an agent-queryable local pipeline.
How it compares
Local browser-capture MCP bridge, not a remote scraping farm or generic Playwright skill pack.
