WebSearchAndCrawl

An MCP Server for Authenticated Web Crawling, Searching, and Document Processing

---.

🚀 Purpose

WebSearchAndCrawl is an MCP (Model Context Protocol) server designed to:

Crawl websites (including authenticated ones) using Firefox session tokens or browser automation.
Search crawled content for regex matches and store results in a structured index.
Download and parse documents (PDF, DOCX, XLSX, etc.) from crawled sites.
Stream results in real-time via HTTP for integration with MCP clients.
Respect robots.txt and enforce rate limits (5 requests/sec, 5 threads max).

This tool is ideal for:

Researchers who need to scrape authenticated or dynamic websites.
Developers building AI agents that require web data.
Automation of repetitive web tasks (e.g., monitoring, data extraction).

🔧 Features

Feature	Description
Authenticated Crawling	Uses Firefox session tokens to access logged-in pages.
Browser Automation	Falls back to Playwright for dynamic content or login forms.
Domain Whitelisting	Only crawls URLs matching a comma-delimited list of domains.
Depth-limited Crawling	Configurable crawl depth (1-9 layers).
Regex Search	Search crawled content or index for regex patterns.
Document Parsing	Extracts text from PDF, DOCX, XLSX, and TXT files.
Real-time Streaming	Results are streamed as JSONL (chunked by page).
Indexing	Stores results in JSON files per domain for later search.
Rate Limiting	Enforces 5 requests/sec and 5 threads max.
Resume Support	Can resume interrupted crawls from checkpoints.
Session Validation	Validates token scopes to prevent misuse.

📦 Installation

1. Clone the Repository

git clone https://github.com/bpweatherill/WebSearchAndCrawl.git
cd WebSearchAndCrawl

2. Set Up a Virtual Environment

python -m venv venv
source venv/bin/activate  # Linux/Mac
# OR
venv\Scripts\activate   # Windows

3. Install Dependencies

pip install -r requirements.txt

4. Install Playwright Browsers

playwright install firefox

5. (Optional) Configure Environment Variables

Create a .env file in the project root:

⚙️ Configuration

Environment Variables

Variable	Default	Description
`MCP_PORT`	`8808`	HTTP server port.
`MCP_HOST`	`0.0.0.0`	HTTP server host.
`MAX_DEPTH`	`9`	Maximum crawl depth (1-9).
`MAX_THREADS`	`5`	Maximum concurrent threads.
`RATE_LIMIT`	`5`	Maximum requests per second.
`REQUEST_TIMEOUT`	`10`	Timeout for requests (seconds).
`MAX_MEMORY_MB`	`1024`	Maximum memory usage (MB).
`FIREFOX_PROFILE`	`None`	Firefox profile name (optional).
`DEFAULT_SEARCH_ENGINE`	`google`	Default search engine.
`INDEX_DIR`	`./index`	Directory for index files.
`DOWNLOADS_DIR`	`./downloads`	Directory for downloaded files.
`CHECKPOINTS_DIR`	`./checkpoints`	Directory for crawl checkpoints.

🛡️ Security Considerations

Session Tokens:
- Tokens are only stored in memory (not persisted to disk).
- Token scopes are validated to prevent misuse (e.g., a token for nasa.gov cannot be used for evil.com).
Input Sanitization:
- All inputs (URLs, regex, etc.) are sanitized to prevent injection attacks.
Rate Limiting:
- Enforces 5 requests/sec and 5 threads max to avoid overwhelming servers.
robots.txt Compliance:
- The crawler respects robots.txt and skips disallowed URLs.
Whitelisting:
- Only URLs matching the whitelisted domains are crawled.

🚀 Enhancements (Roadmap)

Enhancement	Description	Priority
Persistent Tokens	Store tokens in an encrypted file for persistence across restarts.	Medium
Full `robots.txt` Parsing	Properly parse `robots.txt` rules instead of simple checks.	Medium
Advanced Pagination Handling	Detect and follow pagination links (e.g., "Next" buttons).	High
Lazy-Loading Support	Detect and trigger lazy-loaded content (e.g., infinite scroll).	High
Checkpointing	Save crawl state to resume interrupted crawls.	High
Full-Text Search	Support full-text search in addition to regex.	Low
Database Backend	Replace JSON files with SQLite/PostgreSQL for scalability.	Low
Distributed Crawling	Support horizontal scaling with multiple workers.	Low
Docker Support	Add a `Dockerfile` for containerized deployment.	Medium
Authentication Helpers	Built-in support for common auth methods (OAuth, SAML).	Medium
Proxy Support	Add proxy support for crawling behind firewalls.	Low
Custom Headers	Allow users to specify custom headers for requests.	Medium
Webhook Notifications	Notify a webhook URL when new results are found.	Low
