Claude Code n8n Lead Generation: Auto-Capture Buying Intent

Claude Code n8n lead generation connects Claude Code to n8n via the n8n-mcp MCP server so that Claude Code builds and deploys a complete lead gen pipeline in 10 minutes. Claude Code in MCP mode calls create_workflow and update_workflow tools to construct an n8n workflow that scrapes Reddit and Twitter for buying-intent signals, enriches leads with Apify, deduplicates in Google Sheets, and posts new leads to Slack. Build time drops from 45 minutes of manual node dragging to 10 minutes.

THE REAL PROBLEM

Sales development representatives spend 40-50% of their time on lead research — finding prospects, verifying fit, and gathering context before outreach. For a team of 5 SDRs, that is 80-100 hours per week of research time that could go toward actual selling. The core problem is that buying-intent signals are scattered across Reddit threads, Twitter conversations, industry forums, and review sites. Manually monitoring these sources at scale is impractical. Most teams settle for outdated lead lists with 10-20% accuracy because automated scraping and enrichment pipelines take 4-12 hours to build by hand. Claude Code connected to n8n via MCP solves this by generating a complete workflow that monitors multiple social sources simultaneously, enriches each lead with company and contact data, deduplicates automatically, and alerts the team in Slack — all without dragging a single node in the n8n editor.

WHAT IT DOES

This workflow connects Claude Code to n8n via the n8n-mcp MCP server so that Claude Code builds and deploys a complete lead generation pipeline. Claude Code uses its MCP mode to call create_workflow, update_workflow, and execute_workflow tools against the n8n instance. The resulting n8n workflow runs on a schedule, scraping Reddit and Twitter for buying-intent signals using keyword matching on phrases like 'recommend', 'alternatives to', and 'looking for'. Raw mentions flow into an Apify actor for enrichment — Apify pulls company profile data, contact details, and recent activity for each detected lead. Enriched leads enter a Google Sheet where a Code node deduplicates against existing entries by email, username, and company domain. New leads trigger a Slack notification with a structured card showing the lead name, source, intent signal, and enrichment summary. The entire pipeline runs autonomously once configured. Claude Code uses a 2-phase model: reasoning mode to generate the initial workflow JSON and MCP mode to deploy it live to n8n.

WHO THIS IS BUILT FOR

FOR SDR team leads at B2B SaaS companies with 5-20 reps SITUATION: Your team spends 15+ hours weekly on manual lead research from social signals. PAYOFF: Automated pipeline captures 100+ buying-intent leads per week. Reps focus on outreach, not research.

FOR outbound sales managers at agencies running multi-channel prospecting SITUATION: Reddit mentions, tweets, and forum signals are impossible to monitor across 5+ channels manually. PAYOFF: n8n scrapes all sources in parallel. Apify enriches every lead. Slack delivers ready-to-contact leads.

FOR freelance sales consultants managing their own pipeline SITUATION: You cannot afford a full SDR team but need consistent lead flow. PAYOFF: One 10-minute Claude Code session builds a 24/7 lead gen pipeline.

HOW IT RUNS STEP BY STEP

Source Configuration (Claude Code MCP — 2 min) Input: Natural language prompt with target keywords, subreddits, and Twitter accounts Action: Claude calls create_workflow tool in n8n, adds HTTP Request nodes for Reddit and Twitter API Output: Workflow skeleton with Reddit and Twitter source nodes
Intent Filter Setup (Claude Code MCP — 30 sec) Input: Intent keyword list Action: Claude adds IF node with keyword matching logic against post titles and bodies Output: Filtered mention stream passing only buying-intent posts
Apify Enrichment (Claude Code MCP — 30 sec) Input: Raw mention with username, source URL, and post content Action: Claude adds Apify node configured with LinkedIn profile or company enricher actor Output: Enriched lead with company name, title, and recent activity
Google Sheets Logging (Claude Code MCP — 30 sec) Input: Enriched lead data schema Action: Claude adds Google Sheets node with column mapping and dedup key configuration Output: Append-only lead sheet with status tracking columns
Deduplication Logic (Claude Code MCP — 1 min) Input: New lead fields versus existing sheet rows Action: Claude writes a Code node that checks email, username, and company domain matches Output: Lead tagged as new or duplicate with match reference
Slack Notification (Claude Code MCP — 30 sec) Input: New lead object Action: Claude adds Slack node with structured message block — name, source, intent signal, enrichment summary Output: Slack message posted to #leads channel
Schedule Setup (n8n UI manual — 1 min) Input: n8n workflow timer node Action: Set cron schedule for every 4 hours Output: Automated execution on timer trigger

SETUP AND TOOLS

Step 1: Restart your n8n instance fully. The MCP server will not load on a reload — stop and start required. Navigate to Settings > MCP, toggle Instance-level MCP on, and generate an access token. Copy it immediately because n8n shows it only once.

Step 2: Install Claude Code CLI via npm install -g @anthropic-ai/claude-code. Connect it to n8n using the n8n-mcp package:

claude mcp add n8n-mcp -e MCP_MODE=stdio -e LOG_LEVEL=error -e DISABLE_CONSOLE_OUTPUT=true -e N8N_API_URL=https://your-instance.com -e N8N_API_KEY=your-key -- npx n8n-mcp

Step 3: If Claude Code reports 'tool not found', the n8n MCP server is not loaded. Go back to step 1 and fully restart n8n.

Step 4: Prompt Claude Code: 'Build an n8n workflow that scrapes Reddit and Twitter for buying-intent keywords like recommend and looking for, enriches with Apify, deduplicates in Google Sheets, and posts to Slack.' Claude will generate the node structure in 2-3 minutes.

Step 5: Before the workflow can execute, configure credentials in the n8n UI for Google Sheets, Slack, and Apify. Claude Code cannot set these credentials — this is the single most important limitation to understand.

Step 6: Test with a manual execution. If the Slack notification arrives with the correct data, set the Schedule trigger to run every 4 hours.

KPI rows

Build time: 45 minutes manual to 10 minutes with Claude Code MCP
Lead capture: 10-15 manual leads per week to 100+ automated leads per week
SDR time recovered: 15 hours per week per rep to zero hours on lead research
First-week output: 20+ enriched leads in Slack within 24 hours

WHAT IT CANNOT DO

Cannot set credentials (moderate): Claude Code creates all nodes and wiring but cannot inject API keys into n8n credential fields. Every integration needs manual credential entry before the first execution.
Cannot handle MCP server reload failure (moderate): If the n8n MCP server is not fully restarted, Claude Code cannot connect. This is not a Claude Code issue — it is an n8n MCP server limitation. Fully stop and start the instance.
Cannot guarantee perfect intent filtering (minor): Keyword matching catches positive signals but also catches false positives. Review Slack alerts before reaching out. Add Claude Code reasoning mode for semantic verification in a future iteration.
Cannot bypass API rate limits (minor): Twitter and Reddit APIs have request caps. Monitor usage when scaling to 5+ subreddits and 10+ keywords.

START IN 10 MINUTES

Restart n8n fully and enable MCP in Settings. Copy the access token.
Install Claude Code and run the MCP add command with your n8n URL and token.
Prompt Claude: 'Build an n8n lead generation workflow that scrapes Reddit and Twitter for buying-intent keywords, enriches with Apify, deduplicates in Sheets, and posts to Slack.'
Add API credentials manually in n8n UI for Google Sheets, Slack, and Apify.
Test manually. If the Slack alert works, set the schedule to every 4 hours.
