This n8n template demonstrates how to build an autonomous AI news agent using Decodo MCP that automatically finds, scrapes, and delivers fresh industry news to your team via Slack.

Use cases are many – automated news monitoring for your industry, competitive intelligence gathering, startup monitoring, regulatory updates, research automation, or daily briefings for your organization.

How it works

Define your news topics using the Set node – AI, MCP, web scraping, whatever matters to your business.
The AI Agent processes those topics using the Gemini Chat Model, determining which tools to use and when.
Here's where it gets interesting: Decodo MCP gives your AI agent the tools to search Google, scrape websites, and parse content automatically – all while bypassing geo-restrictions and anti-bot measures.
The agent hunts for fresh articles from the last 48 hours, extracts clean data, and returns structured JSON results.
Format Results cleans up the AI's messy output and removes duplicates.
Your polished news digest gets delivered to Slack with clickable links and summaries.

How to use

Schedule trigger runs daily at 9 AM – adjust timing or swap for webhook triggers as needed.
Customize topics in the Set node to match your industry.
Scales effortlessly: add more topics, tweak search criteria, done.

Requirements

Decodo MCP credentials (free trial available) – grab the Smithery connection URL with keys and paste it straight into your n8n MCP node. Done.
Gemini API key for the AI processing – drop it into the Google Gemini Chat Model node and pick whichever Gemini model fits your needs.
Slack workspace for delivery – n8n's Slack integration docs have you covered.

Daily Topic News Digest with Gemini AI, MCP, and Slack

This n8n workflow automates the process of generating a daily news digest on a specific topic using Google Gemini AI, leveraging the Model Context Protocol (MCP) for enhanced AI interaction, and then posting the summary to a Slack channel.

What it does

This workflow performs the following key steps:

Triggers Daily: The workflow is initiated on a scheduled basis (e.g., daily).
Prepares AI Prompt: A "Code" node is used to construct a dynamic prompt for the AI, likely defining the news topic and desired output format.
Sets AI Agent Parameters: An "Edit Fields (Set)" node configures parameters or variables that will be used by the AI agent.
Interacts with AI Agent: An "AI Agent" node (likely a LangChain agent) is used to process the prompt and generate a news digest.
Utilizes MCP Client Tool: The "MCP Client Tool" is integrated, suggesting that the AI agent interacts with the Model Context Protocol for more structured or contextualized information retrieval/generation.
Processes AI Output:
- The AI output is first "Aggregated" to combine items, potentially from multiple AI responses.
- "Remove Duplicates" ensures that the news items or summaries are unique.
- "Split Out" might be used to separate individual news items or sections of the digest for further processing.
Posts to Slack: Finally, the generated news digest is formatted and posted to a designated Slack channel.

Prerequisites/Requirements

n8n Instance: A running n8n instance.
Google Gemini API Key: An API key for accessing the Google Gemini Chat Model.
Slack Account: A Slack workspace and a channel where the news digest will be posted.
Slack API Token: A Slack API token or webhook URL for posting messages.
Model Context Protocol (MCP) Setup: Access to and configuration for the MCP Client Tool, which might involve a separate service or API.

Setup/Usage

Import the workflow: Download the provided JSON and import it into your n8n instance.
Configure Credentials:
- Set up your Google Gemini Chat Model credentials with your API key.
- Configure your Slack credentials with the necessary API token or webhook.
- Ensure the MCP Client Tool is correctly configured with any required API keys or endpoints.
Customize the Schedule Trigger: Adjust the "Schedule Trigger" node to your desired daily frequency and time for the news digest generation.
Customize the "Code" Node: Modify the JavaScript in the "Code" node to define the specific news topic(s) you want the AI to focus on and the desired output structure.
Activate the workflow: Once configured, activate the workflow to start receiving daily news digests in your Slack channel.

Ai website scraper & company intelligence

AI Website Scraper & Company Intelligence Description This workflow automates the process of transforming any website URL into a structured, intelligent company profile. It's triggered by a form, allowing a user to submit a website and choose between a "basic" or "deep" scrape. The workflow extracts key information (mission, services, contacts, SEO keywords), stores it in a structured Supabase database, and archives a full JSON backup to Google Drive. It also features a secondary AI agent that automatically finds and saves competitors for each company, building a rich, interconnected database of company intelligence. --- Quick Implementation Steps Import the Workflow: Import the provided JSON file into your n8n instance. Install Custom Community Node: You must install the community node from: https://www.npmjs.com/package/n8n-nodes-crawl-and-scrape FIRECRAWL N8N Documentation https://docs.firecrawl.dev/developer-guides/workflow-automation/n8n Install Additional Nodes: n8n-nodes-crawl-and-scrape and n8n-nodes-mcp fire crawl mcp . Set up Credentials: Create credentials in n8n for FIRE CRAWL API,Supabase, Mistral AI, and Google Drive. Configure API Key (CRITICAL): Open the Web Search tool node. Go to Parameters → Headers and replace the hardcoded Tavily AI API key with your own. Configure Supabase Nodes: Assign your Supabase credential to all Supabase nodes. Ensure table names (e.g., companies, competitors) match your schema. Configure Google Drive Nodes: Assign your Google Drive credential to the Google Drive2 and save to Google Drive1 nodes. Select the correct Folder ID. Activate Workflow: Turn on the workflow and open the Webhook URL in the “On form submission” node to access the form. --- What It Does Form Trigger Captures user input: “Website URL” and “Scraping Type” (basic or deep). Scraping Router A Switch node routes the flow: Deep Scraping → AI-based MCP Firecrawler agent. Basic Scraping → Crawlee node. Deep Scraping (Firecrawl AI Agent) Uses Firecrawl and Tavily Web Search. Extracts a detailed JSON profile: mission, services, contacts, SEO keywords, etc. Basic Scraping (Crawlee) Uses Crawl and Scrape node to collect raw text. A Mistral-based AI extractor structures the data into JSON. Data Storage Stores structured data in Supabase tables (companies, company_basicprofiles). Archives a full JSON backup to Google Drive. Automated Competitor Analysis Runs after a deep scrape. Uses Tavily web search to find competitors (e.g., from Crunchbase). Saves competitor data to Supabase, linked by company_id. --- Who's It For Sales & Marketing Teams: Enrich leads with deep company info. Market Researchers: Build structured, searchable company databases. B2B Data Providers: Automate company intelligence collection. Developers: Use as a base for RAG or enrichment pipelines. --- Requirements n8n instance (self-hosted or cloud) Supabase Account: With tables like companies, competitors, social_links, etc. Mistral AI API Key Google Drive Credentials Tavily AI API Key (Optional) Custom Nodes: n8n-nodes-crawl-and-scrape --- How It Works Flow Summary Form Trigger: Captures “Website URL” and “Scraping Type”. Switch Node: deep → MCP Firecrawler (AI Agent). basic → Crawl and Scrape node. Scraping & Extraction: Deep path: Firecrawler → JSON structure. Basic path: Crawlee → Mistral extractor → JSON. Storage: Save JSON to Supabase. Archive in Google Drive. Competitor Analysis (Deep Only): Finds competitors via Tavily. Saves to Supabase competitors table. End: Finishes with a No Operation node. --- How To Set Up Import workflow JSON. Install community nodes (especially n8n-nodes-crawl-and-scrape from npm). Configure credentials (Supabase, Mistral AI, Google Drive). Add your Tavily API key. Connect Supabase and Drive nodes properly. Fix disconnected “basic” path if needed. Activate workflow. Test via the webhook form URL. --- How To Customize Change LLMs: Swap Mistral for OpenAI or Claude. Edit Scraper Prompts: Modify system prompts in AI agent nodes. Change Extraction Schema: Update JSON Schema in extractor nodes. Fix Relational Tables: Add Items node before Supabase inserts for arrays (social links, keywords). Enhance Automation: Add email/slack notifications, or replace form trigger with a Google Sheets trigger. --- Add-ons Automated Trigger: Run on new sheet rows. Notifications: Email or Slack alerts after completion. RAG Integration: Use the Supabase database as a chatbot knowledge source. --- Use Case Examples Sales Lead Enrichment: Instantly get company + competitor data from a URL. Market Research: Collect and compare companies in a niche. B2B Database Creation: Build a proprietary company dataset. --- WORKFLOW IMAGE --- Troubleshooting Guide | Issue | Possible Cause | Solution | |-------|----------------|-----------| | Form Trigger 404 | Workflow not active | Activate the workflow | | Web Search Tool fails | Missing Tavily API key | Replace the placeholder key | | FIRECRAWLER / find competitor fails | Missing MCP node | Install n8n-nodes-mcp | | Basic scrape does nothing | Switch node path disconnected | Reconnect “basic” output | | Supabase node error | Wrong table/column names | Match schema exactly | --- Need Help or More Workflows?
