What I Built
I created MarketSense AI, an intelligent agent that provides real-time market intelligence for investors, traders, and financial analysts. By continuously monitoring financial news, social media sentiment, and market data across multiple sources, MarketSense AI delivers actionable insights that help users make informed investment decisions.
Unlike traditional market analysis tools that rely on static or delayed data, MarketSense AI leverages Bright Data's infrastructure to access real-time information from across the web, ensuring users have the most current data available when making critical financial decisions.

How It Works
How I Used Bright Data's Infrastructure
MarketSense AI relies heavily on Bright Data's MCP server to perform all four key actions:
1. Discover
I leveraged Bright Data's web unlocker to discover relevant financial content across diverse sources that would otherwise be inaccessible:
// Example code using Bright Data to discover financial news
const { BrightData } = require('bright-data');
const brightData = new BrightData({
auth: process.env.BRIGHT_DATA_TOKEN
});
const discoverFinancialNews = async (ticker) => {
const searchResults = await brightData.discoverContent({
query: `${ticker} financial news analysis`,
sources: ['news', 'blogs', 'forums'],
timeRange: 'past_24h'
});
return searchResults;
};
2. Access
MarketSense AI leverages Bright Data's capabilities to access:
// Example of accessing protected financial content
const accessFinancialData = async (url, credentials) => {
const browser = await brightData.createBrowser({
stealth: true,
cookies: credentials.cookies
});
const page = await browser.newPage();
await page.goto(url);
// Handle login if needed
if (await page.$('.login-form')) {
await page.type('#username', credentials.username);
await page.type('#password', credentials.password);
await page.click('.login-button');
await page.waitForNavigation();
}
// Now access the protected content
const content = await page.content();
await browser.close();
return content;
};
3. Extract
The system extracts structured, real-time financial data at scale from:
// Example of extracting structured data from financial sites
const extractMarketData = async (url) => {
const data = await brightData.extract({
url: url,
selectors: {
price: '.current-price',
change: '.price-change',
volume: '.trading-volume',
marketCap: '.market-cap'
}
});
return data;
};
4. Interact
MarketSense AI interacts with web interfaces just as a human would:
// Example of interacting with financial platforms
const generateFinancialReport = async (ticker, timeframe) => {
const browser = await brightData.createBrowser();
const page = await browser.newPage();
await page.goto('https://financial-platform.example.com');
// Enter ticker symbol
await page.type('#search-input', ticker);
await page.click('#search-button');
await page.waitForSelector('.stock-profile');
// Set timeframe in dropdown
await page.click('.timeframe-selector');
await page.click(`[data-value="${timeframe}"]`);
// Generate and download report
await page.click('#generate-report');
await page.waitForSelector('#download-ready');
await page.click('#download-csv');
// Wait for download to complete
const downloadPath = await page.evaluate(() => {
return document.querySelector('#download-link').getAttribute('href');
});
await browser.close();
return downloadPath;
};
Performance Improvements
By leveraging Bright Data's real-time web access capabilities, MarketSense AI significantly outperforms traditional market intelligence solutions:
Speed Advantages
Traditional financial data platforms typically deliver market information with a 15-20 minute delay, while news aggregation can take hours. With MarketSense AI powered by Bright Data:
Traditional approach: Limited to publicly accessible data or expensive subscription services.
MarketSense AI: Comprehensive coverage across paywalled, social, and specialized sources.
Traditional approach: Often relies on incomplete data and misses crucial context from diverse sources.
MarketSense AI: Combines data from hundreds of sources to provide a holistic market view.
Business Impact
These performance improvements translate to tangible business value:
MarketSense AI is built on a modern tech stack:
System Overview
The system consists of five primary components:
The frontend is built with Next.js and Tailwind CSS, providing a responsive and intuitive interface:
The backend architecture uses Node.js with Express, organized as microservices:
The data architecture uses a hybrid approach for optimal performance:
MarketSense AI leverages several ML models for financial intelligence:
The system is deployed across multiple cloud services for reliability:
I'm continuing to enhance MarketSense AI with:
MarketSense AI demonstrates how Bright Data's infrastructure can power sophisticated AI agents that deliver real business value. By providing instant access to comprehensive financial intelligence, MarketSense AI helps users make smarter investment decisions based on current information.
The project showcases Bright Data's MCP server's four key capabilities: discovering relevant content across the web, accessing even protected sites, extracting structured data at scale, and interacting with complex web interfaces just as a human would.

How I Used Bright Data's Infrastructure
MarketSense AI relies heavily on Bright Data's MCP server to perform all four key actions:
1. Discover
I leveraged Bright Data's web unlocker to discover relevant financial content across diverse sources that would otherwise be inaccessible:
- Financial news sites with paywalls (WSJ, Financial Times, Bloomberg)
- Investment forums with complex authentication requirements
- Specialized financial data providers with rate limiting
- Social media platforms with API restrictions
// Example code using Bright Data to discover financial news
const { BrightData } = require('bright-data');
const brightData = new BrightData({
auth: process.env.BRIGHT_DATA_TOKEN
});
const discoverFinancialNews = async (ticker) => {
const searchResults = await brightData.discoverContent({
query: `${ticker} financial news analysis`,
sources: ['news', 'blogs', 'forums'],
timeRange: 'past_24h'
});
return searchResults;
};
2. Access
MarketSense AI leverages Bright Data's capabilities to access:
- Dynamic JavaScript-rendered financial dashboards
- Financial sites with sophisticated bot protection
- Login-protected investor forums and research portals
- Financial data terminals with complex UI
// Example of accessing protected financial content
const accessFinancialData = async (url, credentials) => {
const browser = await brightData.createBrowser({
stealth: true,
cookies: credentials.cookies
});
const page = await browser.newPage();
await page.goto(url);
// Handle login if needed
if (await page.$('.login-form')) {
await page.type('#username', credentials.username);
await page.type('#password', credentials.password);
await page.click('.login-button');
await page.waitForNavigation();
}
// Now access the protected content
const content = await page.content();
await browser.close();
return content;
};
3. Extract
The system extracts structured, real-time financial data at scale from:
- Stock price feeds and market indices
- Company financial statements
- Analyst reports and predictions
- Regulatory filings
- Social sentiment indicators
// Example of extracting structured data from financial sites
const extractMarketData = async (url) => {
const data = await brightData.extract({
url: url,
selectors: {
price: '.current-price',
change: '.price-change',
volume: '.trading-volume',
marketCap: '.market-cap'
}
});
return data;
};
4. Interact
MarketSense AI interacts with web interfaces just as a human would:
- Navigating complex financial dashboards
- Clicking through multi-page reports
- Adjusting filters and parameters on data visualizations
- Downloading CSV reports and data exports
// Example of interacting with financial platforms
const generateFinancialReport = async (ticker, timeframe) => {
const browser = await brightData.createBrowser();
const page = await browser.newPage();
await page.goto('https://financial-platform.example.com');
// Enter ticker symbol
await page.type('#search-input', ticker);
await page.click('#search-button');
await page.waitForSelector('.stock-profile');
// Set timeframe in dropdown
await page.click('.timeframe-selector');
await page.click(`[data-value="${timeframe}"]`);
// Generate and download report
await page.click('#generate-report');
await page.waitForSelector('#download-ready');
await page.click('#download-csv');
// Wait for download to complete
const downloadPath = await page.evaluate(() => {
return document.querySelector('#download-link').getAttribute('href');
});
await browser.close();
return downloadPath;
};
