## What it does

This server links development agents directly to the Vaquill API for regulatory research across US federal codes and state statutes. Agents run keyword queries or hybrid semantic scans across court rules and regulatory guidance. Up to 50 statutory sections can be pulled simultaneously with metadata and full text.

Tools load dynamically from the OpenAPI declaration during startup. The US setup provides 26 endpoints while the Indian corpus provides 22. Every single endpoint operates in read-only mode. Each server instance targets only one legal corpus at a time. Querying both jurisdictions requires defining two separate client entries, with India activated via `--jurisdiction IN`.

A personal key from `vaquill.ai` is mandatory whether connecting through `uvx` or using remote endpoints. Without passing the credential in `VAQUILL_API_KEY` or the `Authorization` header, requests will fail. Regulatory tracking boards and change alerts stay outside this toolset and require the web dashboard or direct REST calls.
