LangGraph.js with MCP <-> Firecrawl | gotoHuman

AI agent example built with LangGraph's MCP adapter connecting with Firecrawl for web scraping via Composio and using gotoHuman for approvals by subject-matter experts.

Setup

• Get Firecrawl API key at firecrawl.dev/app
• Get URL of your Composio Firecrawl MCP server at mcp.composio.dev/firecrawl
  • No proper auth handling in Composio's MCPs yet, so install the MCP server in Cursor first, do a test scrape and pass a restricted demo Firecrawl API key when asked. Now the connection is initialized.
• Get gotoHuman API key and set up review at app.gotohuman.com
