Overview
What is Lionscraper Mcp?

FAQ from Lionscraper Mcp
Extension not connected or scrape fails?
Check that the extension is enabled, the bridge port matches the PORT env variable, and only one MCP config per machine is running.
Seeing MCP tools in the client means everything works?

What runtimes are required?
Node.js 18+ or Python 3.10+.
How to install without global install?
Use npx in the MCP config: "npx -y lionscraper lionscraper-mcp" as command and args.
What is the default port and timeout?
Default PORT is 13808, default TIMEOUT is 120000 ms (2 minutes).
