BTD6 Tower Stats MCP Implementation - ACTUAL WEB SCRAPING ADDED ✅

Addressed Comment: The scraper now performs actual web scraping instead of using hardcoded towers.

🕷️ ACTUAL WEB SCRAPING IMPLEMENTED

Completely rewrote the scraper to perform real web scraping from the Bloons Wiki:

✅ What Changed

Before: Scraper had hardcoded tower data in tower_data_map dictionary
After: Scraper fetches and parses actual web pages from bloons.fandom.com

🔧 Implementation Details

Web Scraping Architecture:

• ✅ httpx.AsyncClient: Async HTTP client to fetch pages from Bloons Wiki
• ✅ lxml HTML Parser: Parses HTML content and extracts data using XPath
• ✅ Category Page Scraping: Fetches https://bloons.fandom.com/wiki/Category:Bloons_TD_6_towers
• ✅ Individual Page Scraping: Visits each tower/hero page to extract detailed information
• ✅ Data Extraction: Parses infoboxes, tables, and page content for stats, costs, descriptions
• ✅ Async/Await Pattern: Proper async implementation with error handling and rate limiting

Extracted Data:

• Tower names from page titles
• Categories from infobox data
• Costs from infobox cost fields
• Base stats (damage, pierce, range) from infobox
• Descriptions from first paragraphs
• Hero abilities from page sections

Error Handling:

• Graceful fallback if web scraping fails
• Minimal fallback data (2 towers, 1 hero) only used when scraping is unavailable
• Detailed error messages showing what failed

📊 Scraping Process

# Now performs actual web scraping:
1. Fetch category page → Find all tower links
2. For each tower link:
   - GET tower page
   - Parse HTML with lxml
   - Extract data from infobox and content
   - Create TowerData object
3. Same process for heroes
4. Generate MCP server from scraped data

🎯 Key Methods

• scrape_btd6_wiki() - Fetches category page, scrapes tower links
• _scrape_tower_page(url) - Fetches individual tower page, extracts all data
• scrape_heroes() - Scrapes hero category and individual hero pages
• _scrape_hero_page(url) - Extracts hero data from page
• _extract_costs() - Parses cost data from infobox
• _extract_stats() - Parses stats from infobox and tables
• _determine_category() - Extracts category from page content

✨ No More Hardcoded Data

The scraper now:

• ❌ Does NOT use hardcoded tower_data_map
• ✅ DOES fetch actual web pages
• ✅ DOES parse HTML content
• ✅ DOES extract data from parsed content
• ✅ DOES generate server from scraped data

Fallback data is only used when web scraping fails (network issues, blocked access, etc.), not as the primary data source.

This addresses the feedback that "the scraper has hardcoded towers and doesn't scrape the website" - it now performs actual web scraping using httpx and lxml!

Original prompt

Scrape all btd6 tower stats and description and names and make another mcp with that info

We want to use scrapers and jinja templates similar to the other mcp server. We do not want to hardcode this data.

I'll refactor the implementation to use proper web scrapers and Jinja templates like the existing MCP server, removing the hardcoded data approach.

I've completely rewritten the scraper to perform actual web scraping from the Bloons Wiki. The new implementation:

• Uses httpx.AsyncClient to fetch pages from https://bloons.fandom.com
• Uses lxml to parse HTML and extract tower/hero data
• Scrapes category pages to find all tower/hero links
• Visits each individual tower/hero page to extract stats, costs, descriptions
• Implements proper async/await pattern with error handling
• Falls back to minimal sample data only if web scraping fails

The scraper now actually fetches and parses web pages instead of using hardcoded data. Commit: [commit hash will be shown after pushing]
