Web Research Assistant: Automated Search & Scraping with Gemini AI and Spreadsheet Reports

⚠️ IMPORTANT: This template requires self-hosted n8n hosting due to the use of community nodes (MCP tools). It will not work on n8n Cloud. Make sure you have access to a self-hosted n8n instance before using this template.

Overview

This workflow automation allows a Google Gemini-powered AI Agent to orchestrate multi-source web intelligence using MCP (Model Context Protocol) tools such as Firecrawl, Brave Search, and Apify.

The system allows users to interact with the agent in natural language, which then leverages various external data collection tools, processes the results, and automatically organizes them into structured spreadsheets.

With built-in memory, flexible tool execution, and conversational capabilities, this workflow acts as a multi-agent research assistant, capable of retrieving, synthesizing, and delivering actionable insights in real time.

How the system works

AI Agent + MCP Pipeline

1. User Interaction
   A chat message is received and forwarded to the AI Agent.

2. AI Orchestration
   The agent, powered by Google Gemini, decides which MCP tools to invoke based on the query.

   • Firecrawl-MCP: Recursive web crawling and content extraction.
   • Brave-MCP: Real-time web search with structured results.
   • Apify-MCP: Automation of web scraping tasks with scalable execution.

3. Memory Management
   A memory module stores context across conversations, ensuring multi-turn reasoning and task continuity.

4. Spreadsheet automation
   Results are structured in a new, automatically created Google Spreadsheet, enriched with formatting and additional metadata.

5. Data processing
   The workflow generates the spreadsheet content, updates the sheet, and improves results via HTTP requests and field edits.

6. Delivery of results
   Users receive a structured and contextualized dataset ready for review, analysis, or integration into other systems.

Configuration instructions

Estimated setup time: 45 minutes

Prerequisites

• Self-hosted n8n instance (v0.200.0 or higher recommended)
• Google Gemini API key
• MCP-compatible nodes (Firecrawl, Brave, Apify) configured
• Google Sheets credentials for spreadsheet automation

Detailed configuration steps

Step 1: Configuring the AI Agent

• AI Agent node:
  • Select Google Gemini as the LLM model
  • Configure your Google Gemini API key in the n8n credentials
  • Set the system prompt to guide the agent's behavior
  • Connect the Simple Memory node to enable context tracking

Step 2: Integrating MCP Tools

• Firecrawl-MCP Configuration:

  • Install the @n8n/n8n-nodes-firecrawl-mcp package
  • Configure your Firecrawl API key
  • Set crawling parameters (depth, CSS selectors)

• Brave-MCP configuration:

  • Install the @n8n/n8n-nodes-brave-mcp package
  • Add your Brave Search API key
  • Configure search filters (region, language, SafeSearch)

• Apify-MCP configuration:

  • Install the @n8n/n8n-nodes-apify-mcp package
  • Configure your Apify credentials
  • Select the appropriate actors for your use cases

Step 3: Spreadsheet automation

• “Create Spreadsheet” node:

  • Configure Google Sheets authentication (OAuth2 or Service Account)
  • Set the file name with dynamic timestamps
  • Specify the destination folder in Google Drive

• “Generate Spreadsheet Content” node:

  • Transform the agent's outputs into tabular format
  • Define the columns: URL, Title, Description, Source, Timestamp
  • Configure data formatting (dates, links, metadata)

• “Update Spreadsheet” node:

  • Insert the data into the created sheet
  • Apply automatic formatting (headers, colors, column widths)
  • Add summary formulas if necessary

Step 4: Post-processing and delivery

• “Data Enrichment Request” node (formerly “HTTP Request1”):

  • Configure optional API calls to enrich the data
  • Add additional metadata (geolocation, sentiment, categorization)
  • Manage errors and timeouts

• “Edit Fields” node:

  • Refine the final dataset (metadata, tags, filters)
  • Clean and normalize the data
  • Prepare the final response for the user

Structure of generated Google Sheets
