Building a ManyChat-Style System with Claude Code and MCP Servers
Executive Summary
Link to prompt conversation
This guide shows you how to build a keyword-triggered chatbot automation system similar to ManyChat, but using Claude Code and MCP servers. This approach can save 70-90% in costs compared to commercial platforms like ManyChat.
Cost Comparison:
ManyChat Pro: $15-$150+/month depending on contacts
Your system: ~$5-20/month (API costs + hosting)
What you'll build:
Keyword detection and intent routing
Multi-channel support (WhatsApp, Telegram, Discord, Slack)
Flow automation with branching logic
CRM integration
Analytics and monitoring
User tagging and segmentation

Step 2: Set Up Database Schema
2.1 Database Design
Create src/database/schema.sql:
-- Users table
CREATE TABLE users (
id INTEGER PRIMARY KEY AUTOINCREMENT,
platform VARCHAR(50) NOT NULL, -- 'whatsapp', 'telegram', 'discord', 'slack'
platform_user_id VARCHAR(255) NOT NULL,
username VARCHAR(255),
phone VARCHAR(50),
email VARCHAR(255),
tags TEXT, -- JSON array of tags
custom_fields TEXT, -- JSON object for custom data
created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
updated_at DATETIME DEFAULT CURRENT_TIMESTAMP,
UNIQUE(platform, platform_user_id)
);
-- Conversations table
CREATE TABLE conversations (
id INTEGER PRIMARY KEY AUTOINCREMENT,
user_id INTEGER NOT NULL,
platform VARCHAR(50) NOT NULL,
status VARCHAR(50) DEFAULT 'active', -- 'active', 'completed', 'abandoned'
current_flow VARCHAR(255),
current_step INTEGER DEFAULT 0,
context TEXT, -- JSON object for conversation state
started_at DATETIME DEFAULT CURRENT_TIMESTAMP,
last_activity DATETIME DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (user_id) REFERENCES users(id)
);
-- Messages table
CREATE TABLE messages (
id INTEGER PRIMARY KEY AUTOINCREMENT,
conversation_id INTEGER NOT NULL,
direction VARCHAR(10) NOT NULL, -- 'inbound', 'outbound'
content TEXT NOT NULL,
metadata TEXT, -- JSON for attachments, etc.
created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (conversation_id) REFERENCES conversations(id)
);
-- Flows table
CREATE TABLE flows (
id INTEGER PRIMARY KEY AUTOINCREMENT,
name VARCHAR(255) NOT NULL UNIQUE,
description TEXT,
trigger_keywords TEXT NOT NULL, -- JSON array
flow_definition TEXT NOT NULL, -- JSON flow structure
is_active BOOLEAN DEFAULT 1,
created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
updated_at DATETIME DEFAULT CURRENT_TIMESTAMP
);
-- Analytics table
CREATE TABLE analytics (
id INTEGER PRIMARY KEY AUTOINCREMENT,
event_type VARCHAR(100) NOT NULL,
user_id INTEGER,
conversation_id INTEGER,
flow_name VARCHAR(255),
metadata TEXT, -- JSON for additional data
created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);
-- Create indexes
CREATE INDEX idx_users_platform_user_id ON users(platform, platform_user_id);
CREATE INDEX idx_conversations_user_id ON conversations(user_id);
CREATE INDEX idx_messages_conversation_id ON messages(conversation_id);
CREATE INDEX idx_analytics_event_type ON analytics(event_type);
CREATE INDEX idx_analytics_created_at ON analytics(created_at);
2.2 Initialize Database
Create src/database/init.js:
const sqlite3 = require('sqlite3').verbose();
const fs = require('fs');
const path = require('path');
const DB_PATH = path.join(__dirname, '../../data/chatbot.db');
function initDatabase() {
return new Promise((resolve, reject) => {
const db = new sqlite3.Database(DB_PATH, (err) => {
if (err) {
reject(err);
return;
}
console.log('Connected to SQLite database');
// Read and execute schema
const schema = fs.readFileSync(
path.join(__dirname, 'schema.sql'),
'utf8'
);
db.exec(schema, (err) => {
if (err) {
reject(err);
return;
}
console.log('Database schema created successfully');
resolve(db);
});
});
});
}
module.exports = { initDatabase, DB_PATH };
Step 3: Build the Keyword Detection Engine
3.1 Simple Pattern Matcher
Create src/services/keywordMatcher.js:
class KeywordMatcher {
constructor() {
this.keywords = new Map();
this.regexPatterns = new Map();
}
// Register a keyword with its flow
registerKeyword(keyword, flowName, options = {}) {
const config = {
matchType: options.matchType || 'contains', // 'exact', 'contains', 'regex'
caseSensitive: options.caseSensitive || false,
priority: options.priority || 0
};
if (config.matchType === 'regex') {
this.regexPatterns.set(flowName, {
pattern: new RegExp(keyword, config.caseSensitive ? '' : 'i'),
priority: config.priority
});
} else {
const key = config.caseSensitive ? keyword : keyword.toLowerCase();
if (!this.keywords.has(key)) {
this.keywords.set(key, []);
}
this.keywords.get(key).push({
flowName,
matchType: config.matchType,
priority: config.priority
});
}
}
// Match incoming message against keywords
match(message) {
const matches = [];
const processedMessage = message.toLowerCase().trim();
// Check exact and contains matches
for (const [keyword, flows] of this.keywords.entries()) {
for (const flow of flows) {
let isMatch = false;
if (flow.matchType === 'exact') {
isMatch = processedMessage === keyword;
} else if (flow.matchType === 'contains') {
isMatch = processedMessage.includes(keyword);
}
if (isMatch) {
matches.push({
flowName: flow.flowName,
keyword: keyword,
priority: flow.priority,
matchType: flow.matchType
});
}
}
}
// Check regex patterns
for (const [flowName, config] of this.regexPatterns.entries()) {
if (config.pattern.test(message)) {
matches.push({
flowName,
keyword: 'regex',
priority: config.priority,
matchType: 'regex'
});
}
}
// Sort by priority (highest first)
matches.sort((a, b) => b.priority - a.priority);
return matches.length > 0 ? matches[0] : null;
}
// Load keywords from database
async loadFromDatabase(db) {
return new Promise((resolve, reject) => {
db.all('SELECT * FROM flows WHERE is_active = 1', (err, rows) => {
if (err) {
reject(err);
return;
}
for (const flow of rows) {
const keywords = JSON.parse(flow.trigger_keywords);
for (const keywordConfig of keywords) {
this.registerKeyword(
keywordConfig.keyword,
flow.name,
keywordConfig.options || {}
);
}
}
console.log(`Loaded ${rows.length} flows with keywords`);
resolve();
});
});
}
}
module.exports = KeywordMatcher;
3.2 Claude-Powered Intent Detection
Create src/services/intentDetector.js:
const Anthropic = require('@anthropic-ai/sdk');
class IntentDetector {
constructor(apiKey) {
this.client = new Anthropic({ apiKey });
}
async detectIntent(message, availableFlows) {
const flowDescriptions = availableFlows.map(f =>
`- ${f.name}: ${f.description}`
).join('\n');
const prompt = `You are an intent classifier for a chatbot system.
Available flows:
${flowDescriptions}
User message: "${message}"
Analyze the user's intent and respond with ONLY a JSON object in this exact format:
{
"flowName": "the most appropriate flow name or null",
"confidence": 0.0 to 1.0,
"reasoning": "brief explanation"
}
If no flow matches well (confidence < 0.5), set flowName to null.`;
try {
const response = await this.client.messages.create({
model: 'claude-sonnet-4-20250514',
max_tokens: 500,
messages: [{ role: 'user', content: prompt }]
});
const text = response.content[0].text.trim();
const json = JSON.parse(text);
return {
flowName: json.confidence >= 0.5 ? json.flowName : null,
confidence: json.confidence,
reasoning: json.reasoning
};
} catch (error) {
console.error('Intent detection error:', error);
return { flowName: null, confidence: 0, reasoning: 'Error' };
}
}
}
module.exports = IntentDetector;
Step 4: Build the Flow Execution Engine
4.1 Flow Definition Schema
Create src/flows/flowSchema.js:
// Example flow structure
const exampleFlow = {
name: 'demo_request',
description: 'Handle demo requests',
steps: [
{
id: 'welcome',
type: 'message',
content: 'Thanks for your interest! I\'d love to help you schedule a demo.',

inputType: 'text',
saveAs: 'industry',
next: 'ask_company_size'

type: 'question',
content: 'How many employees does your company have?',
inputType: 'buttons',
options: [

saveAs: 'company_size'
},
{

type: 'message',
content: 'Perfect for a growing business! Let me connect you with our startup specialist.',
actions: [
{ type: 'tag', value: 'small-business-lead' },
{ type: 'notify', channel: 'slack', message: 'New small business demo request' }
],
next: 'schedule_demo'
},
{
id: 'schedule_demo',
type: 'message',
content: 'Here\'s a link to book a time: https://calendly.com/demo',
actions: [
{ type: 'track', event: 'demo_link_sent' }
],
next: 'end'
},
{
id: 'end',
type: 'end',
content: 'Looking forward to speaking with you!'
}
]
};
module.exports = { exampleFlow };
4.2 Flow Executor
Create src/services/flowExecutor.js:
const Anthropic = require('@anthropic-ai/sdk');
class FlowExecutor {
constructor(db, anthropicClient) {
this.db = db;
this.client = anthropicClient;
}
// Get or create conversation
async getConversation(userId, platform) {

// Start a new flow
async startFlow(userId, platform, flowName) {
const flow = await this.loadFlow(flowName);

// Create new conversation
const conversationId = await this.createConversation(userId, platform, flowName);
// Execute first step
const firstStep = flow.steps[0];
const response = await this.executeStep(conversationId, flow, firstStep, null);
return { conversationId, response };
}
// Continue an existing flow
async continueFlow(conversationId, userInput) {
const conversation = await this.getConversationById(conversationId);
const flow = await this.loadFlow(conversation.current_flow);
const context = JSON.parse(conversation.context || '{}');
// Get current step
const currentStep = flow.steps.find(s => s.id === context.currentStepId);
if (!currentStep) {
throw new Error('Invalid flow state');

// Save user input if needed

Step 7: Set Up Platform Integrations
7.1 WhatsApp Integration
Create src/integrations/whatsapp.js:
const axios = require('axios');
class WhatsAppIntegration {
constructor(phoneNumberId, accessToken) {
this.phoneNumberId = phoneNumberId;
this.accessToken = accessToken;
this.baseUrl = 'https://graph.facebook.com/v18.0';

messaging_product: 'whatsapp',
to: to,
type: 'text',
text: { body: text }
},
{
headers: {
'Authorization': `Bearer ${this.accessToken}`,
'Content-Type': 'application/json'
}
}
);
} catch (error) {
console.error('WhatsApp send error:', error);
throw error;
}
}
async sendButtons(to, bodyText, buttons) {
const buttonComponents = buttons.slice(0, 3).map(btn => ({
type: 'reply',
reply: {
id: btn.value,
title: btn.label.slice(0, 20) // Max 20 chars
}
}));
try {
await axios.post(
`${this.baseUrl}/${this.phoneNumberId}/messages`,

action: {
buttons: buttonComponents
}
}
},
{
headers: {
'Authorization': `Bearer ${this.accessToken}`,
'Content-Type': 'application/json'
}
}
);
} catch (error) {
console.error('WhatsApp send buttons error:', error);
throw error;
}
}
}
module.exports = WhatsAppIntegration;
7.2 Telegram Integration
Create src/integrations/telegram.js:
const axios = require('axios');
class TelegramIntegration {
constructor(botToken) {
this.botToken = botToken;
this.baseUrl = `https://api.telegram.org/bot${botToken}`;
}
async sendMessage(chatId, text) {

];
for (const flow of flows) {
await new Promise((resolve, reject) => {

seedFlows().catch(console.error);
Run: node src/database/seed.js
Step 10: Deploy and Test
10.1 Local Testing
# Start the server
npm run dev
# Test with curl
curl -X POST http://localhost:3000/webhook/telegram \
-H "Content-Type: application/json" \
-d '{
"message": {
"from": {"id": 12345},
"text": "I want a demo",
"message_id": 1
}
}'
10.2 Deploy to Production

Telegram:
curl -X POST https://api.telegram.org/bot<YOUR_TOKEN>/setWebhook \
-H "Content-Type: application/json" \
-d '{"url": "https://your-domain.com/webhook/telegram"}'
Step 11: Monitor and Optimize
11.1 Add Logging
Create src/utils/logger.js:
const winston = require('winston');
const logger = winston.createLogger({
level: 'info',
format: winston.format.json(),
transports: [
new winston.transports.File({ filename: 'logs/error.log', level: 'error' }),
new winston.transports.File({ filename: 'logs/combined.log' }),
new winston.transports.Console({
format: winston.format.simple()
})
]
});
module.exports = logger;
11.2 Create Analytics Dashboard
Create src/routes/dashboard.js:
const express = require('express');
const router = express.Router();
router.get('/dashboard', async (req, res) => {
// Query analytics from database
const metrics = await getMetrics();
res.json({
total_users: metrics.total_users,
active_conversations: metrics.active_conversations,
flows_triggered: metrics.flows_triggered,
top_keywords: metrics.top_keywords,
conversion_rate: metrics.conversion_rate
});
});
async function getMetrics() {
// Implementation
return {
total_users: 150,
active_conversations: 12,
flows_triggered: 340,
top_keywords: ['demo', 'pricing', 'help'],
conversion_rate: 0.45
};
}
module.exports = router;
Cost Analysis
ManyChat Pro Plan
$15-50/month for 500-1,000 contacts
$150+/month for 5,000+ contacts
Limited customization
Platform lock-in
Your Custom System
Anthropic API: ~$5-15/month (500-2,000 completions)
Hosting: $5-10/month (Railway/DigitalOcean)
Total: ~$10-25/month
Savings: 70-90%
Cost Per Conversation
ManyChat: $0.03-0.05
Your system: $0.005-0.01
5-10x cheaper
Step 12: Add Survey Functionality with Personalized Email Outreach
12.1 Survey Flow Builder
Create src/flows/surveyFlow.js:
class SurveyFlow {
constructor() {
this.surveyDefinitions = new Map();
}
// Define a survey with multiple questions
createSurvey(surveyName, config) {
const surveySteps = [];
// Welcome step
surveySteps.push({
id: 'survey_welcome',
type: 'message',
content: config.welcomeMessage || 'Thanks for taking our survey! This will only take a few minutes.',
next: `question_1`
});
// Generate question steps
config.questions.forEach((question, index) => {
const questionId = `question_${index + 1}`;
const nextQuestionId = index < config.questions.length - 1
? `question_${index + 2}`
: 'survey_complete';
surveySteps.push({
id: questionId,
type: 'question',
content: question.text,
inputType: question.type, // 'text', 'buttons', 'scale', 'multiselect'
options: question.options,
saveAs: question.saveAs,
validation: question.validation,
next: nextQuestionId
});
});
// Survey completion step
surveySteps.push({
id: 'survey_complete',
type: 'message',
content: config.completionMessage || 'Thank you for completing the survey!',
actions: [
{ type: 'tag', value: `survey_${surveyName}_completed` },
{ type: 'track', event: 'survey_completed', metadata: { survey: surveyName } },
{ type: 'trigger_email_flow', surveyName: surveyName }
],
next: 'end'
});
surveySteps.push({
id: 'end',
type: 'end',
content: config.farewellMessage || 'We appreciate your feedback! 🙏'
});
const flow = {
name: `survey_${surveyName}`,
description: config.description,
trigger_keywords: config.triggerKeywords || [],
flow_definition: JSON.stringify(surveySteps)
};
this.surveyDefinitions.set(surveyName, flow);
return flow;
}
// Save survey responses
async saveSurveyResponse(db, userId, surveyName, responses) {
return new Promise((resolve, reject) => {
db.run(
`INSERT INTO survey_responses (user_id, survey_name, responses, completed_at)
VALUES (?, ?, ?, CURRENT_TIMESTAMP)`,
[userId, surveyName, JSON.stringify(responses)],
function(err) {
if (err) reject(err);
else resolve(this.lastID);
}
);
});
}
// Get survey responses for a user
async getSurveyResponses(db, userId, surveyName) {
return new Promise((resolve, reject) => {
db.get(
`SELECT * FROM survey_responses
WHERE user_id = ? AND survey_name = ?
ORDER BY completed_at DESC LIMIT 1`,
[userId, surveyName],
(err, row) => {
if (err) reject(err);
else resolve(row ? { ...row, responses: JSON.parse(row.responses) } : null);
}
);
});
}
}
module.exports = SurveyFlow;
12.2 Update Database Schema for Surveys
Create src/database/surveys-schema.sql:
-- Survey responses table
CREATE TABLE IF NOT EXISTS survey_responses (

FOREIGN KEY (template_id) REFERENCES email_templates(id)
);
CREATE INDEX idx_survey_responses_user ON survey_responses(user_id);
CREATE INDEX idx_survey_responses_survey ON survey_responses(survey_name);
CREATE INDEX idx_email_outreach_user ON email_outreach(user_id);
CREATE INDEX idx_email_outreach_status ON email_outreach(status);
