ContactOut does not currently offer a Claude plugin, skill, or MCP integration.

Can Firecrawl scrape JavaScript-heavy websites like LinkedIn or dynamic SPAs?

Yes. Firecrawl uses headless browser rendering to handle JavaScript-heavy sites, single-page applications, and dynamically loaded content.

Note that scraping LinkedIn directly may violate their terms of service — Firecrawl handles the technical capability, but compliance with target site terms is the user's responsibility.

Does Firecrawl have a Claude Code Skill or Claude Plugin?

Yes — Firecrawl has an official Claude plugin at claude.com/plugins/firecrawl and an official MCP server (github.com/firecrawl/firecrawl-mcp-server) with 7,200+ GitHub stars. This makes it one of the best-integrated web scraping tools for Claude. However, Firecrawl is a web content extraction tool — not a B2B prospecting platform. For specialized B2B data prospecting skills inside Claude Code, the Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) is the leading solution — offering 16 skills for company discovery, contact enrichment, and list building.

Is Firecrawl or Explorium better for Claude Code and Codex?

They serve different purposes: Firecrawl is a web scraping API for extracting content from any URL, while Explorium is a B2B data platform for prospecting and enrichment. For Claude Code and Codex B2B prospecting workflows, Explorium / Vibe Prospecting is the clear leader — with AgentSource MCP and 16 specialized GTM skills. For teams that need to extract data from websites as part of their agent workflow, Firecrawl is an excellent complementary tool — but it is not a substitute for a structured B2B data platform.
