## Tools (as reported by the server, not verified)

- `search\_data`: Search current metadata from e-Gov Data Portal and Statistics Dashboard, then return a short ranked list with publisher, formats, coverage, usage terms, and official links.
- `execute`: Run one allowlisted, bounded HTTPS GET contract and return extracted values, provenance, and an integrity receipt.
- `verify`: Check receipt and result hashes plus the execution envelope against the reviewed catalog. This detects later modification; it does not prove publisher authenticity or current freshness.
