Setup and obtain API token and other necessary information from Bright Data In your Bright Data account, obtain the following information: - API token - Web Unlocker zone name (optional) - Browser API username and password string separated by colon (optional) 3. Host SSE server from STDIO command The methods below will allow you to receive SSE (Server-Sent Events) from Bright Data MCP via a local Supergateway or Smithery Method 1: Run Supergateway in a separate web service (Recommended) This method will work for both cloud version and self-hosted N8N. Signup to any cloud services of your choice (DigitalOcean, Heroku, Hetzner, Render, etc.). For NPM based installation: - Create a new web service. - Choose Node.js as runtime environment and setup a custom server without repository. - In your server’s settings to define environment variables or .env file, add: APITOKEN=yourbrightdataapitoken WEBUNLOCKERZONE=optionalzonename BROWSERAUTH=optionalbrowserauth - Paste the following text as a start command: npx -y supergateway --stdio "npx -y @brightdata/mcp" --port 8000 --baseUrl --ssePath /sse --messagePath /message - Deploy it and copy the web server URL, then append /sse into it. - Your SSE server should now be accessible at: For Docker based installation: - Create a new web service. - Choose Docker as the runtime environment. - Set up your Docker environment by pulling the necessary images or creating a custom Dockerfile. - In your server’s settings to define environment variables or .env file, add: APITOKEN=yourbrightdataapitoken WEBUNLOCKERZONE=optionalzonename BROWSERZONE=optionalbrowserzonename - Use the following Docker command to run Supergateway: docker run -it --rm -p 8000:8000 supercorp/supergateway \ --stdio "npx -y @brightdata/mcp /" \ --port 8000 - Deploy it and copy the web server URL, then append /sse into it. - Your SSE server should now be accessible at: For more installation guides, please refer to Method 2: Run Supergateway in the same web service as the N8N instance This method will only work for self-hosted N8N. a. Set Required Environment Variables In your server's settings to define environment variables or .env file, add: b. Run Supergateway in Background Use the command above to execute it through the cloud shell or set it as a pre-deploy command. Your SSE server should now be accessible at: For more installation guides, please refer to Method 3: Configure via Smithery.ai (Easiest) If you don't want additional setup and want to test it right away, follow these instructions: Visit to: Signup (if you are new to Smithery) Create an API key Define environment variables via a profile Retrieve your SSE server HTTP URL 4. Connect Google Sheets to N8N - Ensure your Google Sheet: - Contains columns like rowid, firstname, lastname, email, and status. - Is shared with your N8N service account (or connected via OAuth) - In N8N: - Add a Google Sheets Trigger node - Set it to watch for new rows in your lead sheet --- 5. Import and Configure the N8N Workflow - Import the provided JSON workflow into N8N - Update nodes with your credentials: - Hubspot: Add your API key or connect it via OAuth. - Google Sheets Trigger: Link to your actual sheet - OpenAI Node: Add your API key - Bright Data Tool Execution: Add Bright Data token and SSE URL --- 🔄 How It Works - New contact in Hubspot or a new row is added to the Google Sheet - N8N triggers the workflow - AI agent classifies the task (e.g., “Find LinkedIn”, “Get company info”) - The relevant MCP tool is called - Results are appended back to the sheet or routed to another destination - Rerun the specific record by specifying status "needs more enrichment", or leaving it blank. --- 🧩 Use Cases - B2B Lead Enrichment – Add missing fields (title, domain, social profiles) - Email Intelligence – Validate and enrich based on email - Market Research – Pull company or contact data on demand - CRM Auto-fill – Push enriched leads to tools like HubSpot or Salesforce --- 🛠️ Customization - Prompt Tuning – Adjust how the AI interprets input data - Column Mapping – Customize which fields to pull from the sheet - Tool Logic – Add retries, fallback tools, or confidence-based routing - Destination Output – Integrate with CRMs, Slack, or webhook endpoints --- ✅ Summary This template turns a Google Sheet into an AI-powered lead enrichment engine.
