WebWatch MCP

A Model Context Protocol (MCP) server for monitoring website changes. Track URLs, detect content changes, compare snapshots, and extract content with CSS selectors — all from your AI assistant.

- Watch URLs— Monitor any webpage for content changes
- CSS Selectors— Track specific elements (prices, headlines, stock info)
- Snapshot History— SQLite-backed storage of every page state
- Diff Detection— See exactly what changed, line by line
- Content Extraction— Pull structured data from any page on demand

# Clone and build git clone https://github.com/leviai-tools/webwatch-mcp.git cd webwatch-mcp npm install npm run build # Or install globally npm install -g @leviai/webwatch-mcp

Add to yourclaude_desktop_config.json:

{ "mcpServers": { "webwatch": { "command": "node", "args": ["/path/to/webwatch-mcp/build/index.js"], "env": { "WEBWATCH_DATA_DIR": "/path/to/data/dir" } } } }

{ "mcpServers": { "webwatch": { "command": "webwatch-mcp" } } }

You: "Watch https://example.com/pricing — track the .pricing-table element" → watch_url(url, selector=".pricing-table", label="Example pricing") You: "Check if pricing changed" → check_now("https://example.com/pricing")

You: "Add these competitor pages to my watchlist" → watch_url for each URL You: "Show me all recent changes" → get_changes(limit=20)

You: "What are the headlines on HN right now?" → extract_content("https://news.ycombinator.com", ".titleline > a")

All data is stored locally in SQLite at~/.webwatch-mcp/webwatch.db(configurable viaWEBWATCH_DATA_DIR).

- watches— Monitored URLs with selectors and labels
