Clone this repository 2. Set up environment variables: ``` export OPENAI_API_KEY=your-openai-key ``` 3. Run the stack: ``` docker compose up ``` --- ### 👁 Usage 1. Go to http://localhost:9111/docs to see the OpenAPI docs 2. Look for the `/fetch_url` endpoint and start a crawl job by providing a URL 3. Use `/job_progress` to see the current job status 4. Configure your editor to use `http://localhost:9111/mcp` as an MCP server --- ### ☁️ Web API #### Core Endpoints - `POST /fetch_url`: Start crawling a URL - `GET /search_docs`: Search indexed documents - `GET /job_progress`: Check crawl job progress - `GET /list_doc_pages`: List indexed pages - `GET /get_doc_page`: Get full text of a page #### Site Map Feature The Maps feature provides a hierarchical view of crawled websites, making it easy to navigate and explore the structure of indexed sites. **Endpoints:** - `GET /map`: View an index of all crawled sites - `GET /map/site/{root_page_id}`: View the hierarchical tree structure of a specific site - `GET /map/page/{page_id}`: View a specific page with navigation (parent, siblings, children) - `GET /map/page/{page_id}/raw`: Get the raw markdown content of a page **Features:** - **Hierarchical Navigation**: Pages maintain parent-child relationships, allowing you to navigate through the site structure - **Domain Grouping**: Pages from the same domain crawled individually are automatically grouped together - **Automatic Title Extraction**: Page titles are extracted from HTML or markdown content - **Breadcrumb Navigation**: Easy navigation with breadcrumbs showing the path from root to current page - **Sibling Navigation**: Quick access to pages at the same level in the hierarchy - **Legacy Page Support**: Pages crawled before hierarchy tracking are grouped by domain for easy access - **No JavaScript Required**: All navigation works with pure HTML and CSS for maximum compatibility **Usage Example:** 1. Crawl a website using the `/fetch_url` endpoint 2. Visit `/map` to see all crawled sites 3. Click on a site to view its hierarchical structure 4. Navigate through pages using the provided links --- ### 🔧 MCP Integration Ensure that your Docker Compose stack is up, and then add to your Cursor or VSCode MCP Servers configuration: ```json "doctor": { "type": "sse", "url": "http://localhost:9111/mcp" } ``` --- ### 🧪 Testing #### Running Tests To run all tests: ```bash # Run all tests with coverage report pytest ``` To run specific test categories: ```bash # Run only unit tests pytest -m unit # Run only async tests pytest -m async_test # Run tests for a specific component pytest tests/lib/test_crawler.py ``` #### Test Coverage The project is configured to generate coverage reports automatically: ```bash # Run tests with detailed coverage report pytest --cov=src --cov-report=term-missing ``` #### Test Structure - `tests/conftest.py`: Common fixtures for all tests - `tests/lib/`: Tests for library components - `test_crawler.py`: Tests for the crawler module - `test_crawler_enha
