Vaquill MCP with Claude: Faster US Legal Research and Citation Checks
The short answer
Claude works with Vaquill through the Model Context Protocol, an open standard that acts as a secure adapter between the two. Once connected with an API key, Claude can search US statutes, run legal research, resolve citations and monitor changes, all through natural language requests. Your organisation controls what Claude can access and approves consequential actions.
What is Vaquill?
Vaquill is an API that gives developers structured access to US statutes, legal research, citation resolution and legal monitoring. It helps development teams access clean legal data and automate research workflows that would otherwise be done by hand. Typical users include legaltech product teams, compliance engineers, in-house technology groups and firms building internal research tools. It is designed for people who build software and need reliable legal information inside their systems.
How Claude connects to Vaquill through MCP
The Model Context Protocol, often called MCP, is an open standard that lets Claude use other software securely. Think of it as a universal adapter between Claude and a tool. Through Vaquill's MCP server or its direct API, Claude can reach the legal data your team has permission to use, without needing custom code for every question.
Once connected, Claude can typically search US statutes, run legal research queries, resolve citations to their source text and check for changes to monitored legal material. Your team describes what it needs in plain language, and Claude translates that into the right requests. For example, a compliance engineer might ask whether a cited section has been amended recently.
Access is controlled by the API key you issue, and you can scope it to the permissions your team needs. Your organisation decides which workflows run automatically and which require a person to review results before they are used. Logs record activity so that every lookup can be traced back to the request that caused it.
What you can automate
Statute search for product teams
A legaltech product manager asks Claude to find every US statute touching a particular topic, such as consumer data retention. Claude queries Vaquill, groups the results by jurisdiction and summarises the key provisions. The team uses the output to scope features faster, with a lawyer reviewing anything that will shape product decisions.
Citation resolution for research tools
A developer building a research assistant needs citations in user documents checked against authoritative text. Claude uses Vaquill to resolve each citation and flag any that cannot be matched. Broken or outdated references are passed to a reviewer, which reduces manual checking and keeps the tool's output more reliable.
Legal change monitoring for compliance
A compliance team wants early warning when rules affecting their business change. Claude monitors the relevant statutes through Vaquill and reports changes in a weekly digest. Staff then assess the impact on policies and systems, so the team spends its time on decisions rather than on scanning sources.
Research automation for internal tools
An engineering lead building an internal legal lookup tool wants staff to ask questions in everyday language. Claude handles the request, pulls structured data from Vaquill and returns cited answers. Developers keep control of what the tool can reach, and the output includes references the team can verify.
Onboarding developers to legal data
A new developer joining a legaltech company must learn how legal data is structured. Claude can explain the data model, run sample queries through Vaquill and show how results are shaped. This shortens the time before the developer can ship useful work.
An end-to-end workflow: Regulatory change alert for a compliance platform
TriggerA compliance analyst asks Claude each Monday to report any changes to statutes covering the company's sector, or a monitored change is detected.
Claude reads the list of statutes the team monitors from the compliance platform.
Claude queries Vaquill's monitoring feature for changes since the last check.
Claude resolves each changed citation to confirm the affected sections and their text.
Claude writes a summary of changes and records them in the company's ticketing system.
A compliance lawyer reviews the summary and approves which items become tasks.
Approved items are assigned in the ticketing system to the relevant policy owners.
OutcomeTeams typically learn about relevant legal changes sooner and with less manual searching. Reviewers spend their time on judgement, and every change is logged and traceable to a named approver.

For teams in the US, UK, India and the Middle East
Organisations in the United States, the United Kingdom, India and the Middle East each have different rules for handling data. In India, the Digital Personal Data Protection Act, 2023 applies to personal data processing. In the UAE and Saudi Arabia, local data protection laws set their own requirements. We choose the hosting region for your application to meet these obligations and agree the data handling approach before launch.
