LionScraper MCP + CLI + HTTP API (Node)
Drive the LionScraper browser extension from your AI agent via MCP, CLI, or HTTP to collect structured data from real logged-in sessions.
Overview
LionScraper Node is a MCP server for the Idea phase that links AI agents to the LionScraper browser extension via stdio, CLI, and HTTP.
What is this MCP server?
- Node package (npm lionscraper v1.0.6) with MCP stdio, CLI, and HTTP API surfaces
- Bridges AI hosts to the LionScraper browser extension for session-authenticated scraping
- Triple entry points: stdio MCP for agents, CLI for scripts, HTTP for local services
- Targets sites that block headless bots but work in a real user browser
- Web automation MCP, not a hosted scraping SaaS by itself
- Package version 1.0.6 on npm identifier lionscraper
- 3 interfaces documented: MCP stdio, CLI, and HTTP API
- Monorepo subfolder packages/node; website lionscraper.com
What problem does it solve?
Your agent cannot reliably extract data from modern sites without a real browser session, but you do not want to maintain separate scraper scripts for every research task.
Who is it for?
Solo builders researching markets, catalogs, or competitor pages that need an extension-backed browser context.
Skip if: Teams that need fully headless cloud scraping with no browser extension or no Node.js in the loop.
What do I get? / Deliverables
After install and extension pairing, your agent can trigger LionScraper-backed collection through MCP tools plus optional CLI or HTTP calls.
- MCP-accessible scraping orchestration tied to the extension
- Optional CLI and local HTTP API for the same scrape bridge
- Structured page data for research or validation artifacts
Recommended MCP Servers
Journey fit
Canonical shelf is Idea because the main solo-builder win is research and discovery—scraping competitors, listings, and pages your agent cannot fetch server-side. Research fits browser-session scraping and competitive intelligence before you commit to a full build.
How it compares
Extension-bridged browser scraping MCP, not a database or static HTTP fetch tool.
