Grow Reddit karma with DeepSeek, Google Sheets, Multilogin and Browser MCP

How it works

• Run workflow on schedule fires on a set interval to pull Reddit accounts from a Google Sheets spreadsheet (filtered to exclude shadowbanned accounts)
• Smart action calculator randomly selects 3–8 accounts and decides whether each should post or comment, respecting cooldown timers (1–3hr gap for posts, 30–120min gap for comments) and only operating during active hours (midnight–noon)
• IP validation loop routes each account through a proxy, verifies the IP against the account's creation IP using httpbin, and skips if there's a match (to avoid fingerprint overlap)
• Multilogin browser profile launch opens an anti-detect browser session per account via the Multilogin API, then connects to the browser's DevTools WebSocket
• AI Agent (DeepSeek + Browser MCP) autonomously navigates Reddit, reads subreddit rules, scans recent posts, and either creates a new text post or writes a context-aware comment — all with human-like scroll behavior and natural language
• Post-action processing parses the AI's output to extract karma stats, permalinks, and success/failure status, then updates the Google Sheet with timestamps, karma totals, and links
• Profile cleanup closes the Multilogin browser profile after each account finishes, then loops to the next account

Setup steps

• ~20 minutes to configure all credentials and services
• Connect your Google Sheets service account and point it to your Reddit accounts spreadsheet (columns: multilogin_profile_id, proxy_provider, shadowban?, account_id, account_password, creation_ip, karma, posts_made_today, comments_made_today, time_of_post, time_of_comment, last_allocated_ip, posts_links, comments_links, row_number)
• Set up your Multilogin API bearer token credential and update the folder ID in the "Open Multilogin Profile" node URL
• Add your DeepSeek API credential for both AI Agent model nodes
• Install the Browser MCP community node (n8n-nodes-browser-mcp) and ensure the MCP server is running at the configured baseUrl
• Update the proxy URL in the "Get Proxy Exit IP" HTTP Request node with your actual proxy credentials
• Adjust the Run workflow on schedule interval to your desired frequency
