AI-powered content factory: RSS to blog, Instagram & TikTok with Slack approval
This workflow automates the daily content creation process by monitoring trends, generating drafts for multiple platforms using AI, and requiring human approval before saving. It acts as an autonomous "AI Content Factory" that turns raw news into polished content for SEO Blogs, Instagram, and TikTok/Reels. How it works Trend Monitoring: Fetches the latest trend data via RSS (e.g., Google News or Google Trends). AI Filtering: An AI Agent acts as an "Editor-in-Chief," selecting only the most viral-worthy topics relevant to your niche. Multi-Format Generation: Three specialized AI Agents (using gpt-4o-mini for cost efficiency) run in parallel to generate: An SEO-optimized Blog post structure. An Instagram Carousel plan (5 slides). A Short Video Script (TikTok/Reels). Human-in-the-Loop: Sends a formatted message with interactive buttons to Slack. The workflow waits for your decision. Final Storage: If approved, the content is automatically appended to Google Sheets. Who is this for Social Media Managers & Content Creators Marketing Agencies managing multiple accounts Anyone wanting to automate "research to draft" without losing quality control. Requirements n8n: Version 1.19.0+ (requires AI Agent nodes). OpenAI: API Key (works great with low-cost gpt-4o-mini). Slack: A workspace to receive notifications. Google Sheets: To store the approved content. How to set up Configure Credentials: Set up your OpenAI, Slack, and Google Sheets credentials. Slack App: Create a Slack App, enable "Interactivity," and set the Request URL to your n8n Production Webhook URL. Add the chat:write scope and install it to your workspace. Google Sheet: Create a sheet with columns for Blog, Instagram, and Script (row 1 as headers). RSS Feed: Change the RSS node URL to your preferred topic source.
By Miki AraiControl AI agent tool access with Port RBAC and Slack mentions
RBAC for AI agents with n8n and Port This workflow implements role-based access control for AI agent tools using Port as the single source of truth for permissions. Different users get access to different tools based on their roles, without needing a separate permission database. For example, developers might have access to PagerDuty and AWS S3, while support staff only gets Wikipedia and a calculator. The workflow checks each user's permissions in Port before letting the agent use any tools. For the full guide with blueprint setup and detailed configuration, see RBAC for AI Agents with n8n and Port in the Port documentation. How it works The n8n workflow orchestrates the following steps: Slack trigger — Listens for @mentions and extracts the user ID from the message. Get user profile — Fetches the user's Slack profile to get their email address. Port authentication — Requests an access token from the Port API using client credentials. Permission lookup — Queries Port for the user entity (by email) and reads their allowed_tools array. Unknown user check — If the user doesn't exist in Port, sends an error message and stops. Permission filtering — The "Check permissions" node compares each connected tool against allowed_tools and replaces unauthorized ones with a stub that returns "You are not authorized to use this tool." AI agent — Runs with only permitted tools, using GPT-4 and chat memory. Response — Posts the agent output back to the Slack channel. Setup [ ] Connect your Slack account and set the channel ID in the trigger node [ ] Add your OpenAI API key [ ] Register for free on Port.io [ ] Create the rbacUser blueprint in Port (see full guide for blueprint setup) [ ] Add user entities using email as the identifier [ ] Replace YOURPORTCLIENTID and YOURPORTCLIENTSECRET in the "Get Port access token" node [ ] Connect credentials for any tools you want to use (PagerDuty, AWS, etc.) [ ] Update the channel ID in the Slack nodes [ ] Invite the bot to your Slack channel [ ] You should be good to go! Prerequisites You have a Port account and have completed the onboarding process. You have a working n8n instance (self-hosted) with LangChain nodes available. Slack workspace with bot permissions to receive mentions and post messages. OpenAI API key for the LangChain agent. Port client ID and secret for API authentication. (Optional) PagerDuty, AWS, or other service credentials for tools you want to control. ⚠️ This template is intended for Self-Hosted instances only.
