What if your AI assistant could actually DO things — not just talk about them? With MCP (Model Context Protocol) and 0nMCP, you can build an AI employee that: Responds to customer messages automatically Scores leads and updates your CRM Creates invoices and sends them Posts to social media on schedule Generates reports from your data Here's how. The Architecture You (or a trigger) → Claude/AI → 0nMCP → APIs → Results A trigger fires (new message, schedule, webhook) Claude receives the context 0nMCP executes the required API calls Results flow back Example 1: Auto-Responder When a customer sends a message to your CRM: Webhook fires → hits your endpoint Claude reads the message + contact history Claude generates a personalized response 0nMCP sends the response via CRM API All automatic. Response time: under 10 seconds. Example 2: Lead Scorer When a new contact is created: CRM webhook fires Claude analyzes: email domain, title, company, source Assigns a score 0-100 0nMCP updates the contact with the score and tags High-score leads get tagged "hot" and assigned to sales immediately. Example 3: Content Creator On a daily schedule: Cron triggers the workflow Claude generates a LinkedIn post based on your voice profile 0nMCP posts it via the social media API Done — fresh content every day without lifting a finger Setting It Up Step 1: Install 0nMCP npm install -g 0nmcp Step 2: Connect Your Services Add credentials for the services your AI employee needs: CRM for contacts and conversations Stripe for invoicing Slack for notifications SendGrid for emails Step 3: Create a Workflow Save this as auto-responder.0n: "$0n": "type": "workflow", "version": "1.0.0", "name": "Auto Responder" , "trigger": "type": "webhook", "config": "path": "/hooks/auto-respond" , "steps": [ "id": "step_001", "service": "anthropic", "action": "chat_completion", "params": "model": "claude-sonnet-4-20250514", "messages": ["role": "user", "content": "Generate a reply to: inputs.message"] , "output": "reply" , "id": "step_002", "service": "crm", "action": "send_message", "params": "contactId": "inputs.contactId", "type": "Email", "message": "step_001.output.response" ] Step 4: Run It 0nmcp run auto-responder.0n Your AI employee is now live.
