whed-tools
An MCP-native pipeline for collecting structured intelligence on higher education institutions using the WHED schema, enabling scraping, extraction, validation, and saving of profiles.
README
WHED Tools — Higher Education Intelligence Pipeline
An MCP-native pipeline for collecting structured intelligence on higher education institutions, aligned with the IAU World Higher Education Database (WHED) schema.
Scrape → Extract → Validate → Save — the Host LLM performs extraction directly using MCP tools. No external LLM required.
Built on samirsaci/mcp-webscraper.
Overview
| Step | How |
|---|---|
| Scrape | MCP crawl_website or standalone run_scraper.py — schema-driven crawl, PDF extraction |
| Extract | Host LLM reads scraped content, uses get_extraction_schema + get_db_context |
| Validate | validate_profile — Pydantic schema + WHED DB picklist checks |
| Save | save_profile — write to output/structured/ |
Architecture
┌─────────────────────────────────────────────────────────────────┐
│ HOST LLM (Claude in Cursor / any MCP client) │
│ │
│ crawl_website(url) → get_extraction_schema() │
│ scrape_url(url) get_db_context(domain) │
│ │ │
│ Host LLM reads content and fills JSON │
│ │ │
│ validate_profile(json) → save_profile(domain, json) │

Prerequisites
- Python 3.10+
- uv package manager
- Cursor (for MCP usage)
- MySQL with WHED database (optional — for DB grounding and comparison)
Installation
git clone https://github.com/your-username/mcp-webscraper.git
cd mcp-webscraper
uv sync
uv run playwright install chromium
Copy .env.example to .env and add WHED DB credentials (if available).
Connect MCP to Cursor
Add to .cursor/mcp.json:
{
"mcpServers": {
"whed-tools": {
"command": "uv",
"args": [
"run",
"--directory",
"/path/to/mcp-webscraper",
"python",
"MCP_server/server.py"
]
}
}
}
MCP Tools (whed-tools)
| Tool | Description |
|---|---|
scrape_url |
Fetch HTML from a URL |
extract_data |
Extract by CSS selector |
extract_first |
First matching element |
batch_scrape |
Multiple URLs |
crawl_website |
Discover and crawl site (schema_filter=True to skip irrelevant pages) |
extract_pdf_text |
Download a PDF and extract its text content |
get_extraction_schema |
WHED field template (REQUIRED only) |
get_db_context |
Picklists + reference example for domain |
validate_profile |
Pydantic + DB picklist validation |
save_profile |
Save profile to output/structured/ |
Example prompt
"Crawl https://www.example.edu and extract a WHED profile. Use get_extraction_schema and get_db_context, then validate and save."
Standalone Scripts
Scrape (schema-driven, with PDFs)
Edit run_scraper.py (TARGET_URL, MODE, etc.), then:
uv run python run_scraper.py
- Uses
schema.FIELD_URL_HINTSto follow only relevant URLs - Extracts text from PDFs via
pdfplumber
Schema & DB Grounding
- REQUIRED fields are in
EXTRACTION_TEMPLATE; DEFERRED fields are in Pydantic but not prompted. - With WHED DB: picklists, few-shot examples, and post-validation reduce hallucination.
- Edit
schema.pyto add or reactivate fields.
