# DataPass MCP Server
**Your pass to private datasets.**
This is the MCP (Model Context Protocol) server that powers DataPass. It handles:
- Token validation for dataset access
- SQL and natural language query execution via DuckDB
- Stripe payment integration
- Subscription ledger management
## MCP Endpoint
Connect your MCP client (Claude Desktop, Cursor, etc.) to:
```
sse: https://your-space.hf.space/sse
```
## Available MCP Tools
### Public Tools
- `get_dataset_catalog` - Browse available datasets
### Authenticated Tools (require DataPass token)
- `get_my_datasets` - View your subscribed datasets
- `query_dataset` - Run SQL queries on datasets
- `query_dataset_natural_language` - Ask questions in plain English
- `get_dataset_sample` - Preview dataset structure
## Configuration
This Space requires the following **Secrets** (Settings → Variables and secrets):
| Secret | Description |
|--------|-------------|
| `HF_TOKEN` | HF token with write access to ledger dataset |
| `ADMIN_API_SECRET` | Shared secret for admin API authentication |
| `LEDGER_DATASET_ID` | Dataset ID for subscription ledger (e.g., `username/datapass-ledger`) |
| `STRIPE_SECRET_KEY` | Stripe API key for payments |
| `STRIPE_WEBHOOK_SECRET` | Stripe webhook signing secret |
| `FRONTEND_URL` | URL to DataPass frontend (for landing page redirect) |
## Security Model
- Dataset files never leave Hugging Face
- Every request validates the DataPass token
- Query results are capped (no `SELECT *` dumps)
- Access automatically expires after subscription period
