For solicitors' AI assistants

Your AI drafts the brief.
PolicyHQ checks the law.

Deterministic UK case law search and automated citation verification — delivered as MCP tools to Claude, ChatGPT, and Microsoft Copilot. Your AI assistant gets grounded access to primary legal sources, not probabilistic guesses.

PolicyHQ is an MCP server, not a website you visit for research. Connect it to your AI assistant and it works behind the scenes. No workflow change. No new interface to learn.

PolicyHQ connects via the Model Context Protocol (MCP) — the open standard for AI-to-tool integration.

What is PolicyHQ?

Infrastructure for legal AI

PolicyHQ is not software you install. It is not a website you visit. It is infrastructure — a hosted database of UK case law and legislation that your AI assistant can query in real time, through the Model Context Protocol.

When your AI assistant drafts a brief, conducts research, or checks a reference, it calls PolicyHQ the same way it might check your calendar or search the web. The difference: PolicyHQ returns real judgments and real statutes from a deterministic database, not probabilistic text generation.

Search

Deterministic legal research

Your AI asks a question. PolicyHQ searches 250,000+ UK court judgments and the full statute book semantically — by meaning, not just keywords. It returns the exact paragraphs that answer the question, with neutral citations, court metadata, and links to primary sources. Every result is a real document from The National Archives or legislation.gov.uk. Nothing is generated. Nothing is guessed.

Verify

Automated citation verification

Your AI drafts a document. Before you file it, PolicyHQ checks every legal reference against the primary source database. Does the case exist? Does the statute section exist? Does the text actually say what the document claims? Each citation receives a clear status — verified, uncertain, not found, or outside our current coverage. This is an automated first-pass check, not a replacement for professional judgement. But it catches the errors that have led to sanctions in over 30 UK court cases. 

Claude → PolicyHQ: verify_document(brief_text)

PolicyHQ → Claude:

  Content consistent.

The problem PolicyHQ solves

AI hallucination is a documented legal crisis

1,093
documented cases worldwide of AI-hallucinated legal citations, as at March 2026 — and rising

AI assistants fabricate case citations that look plausible but do not exist. Solicitors who submit these face sanctions, wasted costs orders, and referrals to the SRA.

34%
hallucination rate in Westlaw's own AI research tool (Stanford, 2024)

Even premium, RAG-grounded legal AI tools produce incorrect information at alarming rates. Lexis+ AI hallucinated over 17% of the time. General-purpose tools such as ChatGPT are worse.

0
UK-specific automated citation verification tools available before PolicyHQ

Existing citation checkers cover US jurisdictions only. They cannot parse UK neutral citations, UK legislation references, or UK regulatory handbook codes.

"The vast majority of the authorities are made up or misunderstood."

How PolicyHQ works

Connect once. It works behind the scenes.

PolicyHQ works through the Model Context Protocol. Here is what that means in practice, without the technical detail.

  1. Connect once

    You add PolicyHQ to your AI assistant's connected tools. This takes under two minutes. In Claude, you paste the server URL in Settings. In ChatGPT, you add it in Developer Mode. In Copilot, your IT administrator adds it via Copilot Studio. You enter your API key and you are done. You never need to visit the PolicyHQ website again.

  2. Your AI calls PolicyHQ automatically

    When you ask your AI assistant a legal question, it recognises that it needs authoritative UK legal data. It calls PolicyHQ's search tool behind the scenes — the same way it might search the web or check your calendar. You do not need to type any special commands. Your AI decides when to use PolicyHQ based on your query.

  3. Deterministic results, not guesses

    PolicyHQ searches a database of 250,000+ UK court judgments and the full UK statute book. Results are real documents from real sources — The National Archives and legislation.gov.uk. They are not generated by an AI. They are not probabilistic. Every citation returned by PolicyHQ corresponds to a real, verifiable primary source.

  4. Verify before you file

    When your AI produces a draft, you can ask it to verify the citations before you finalise. Your AI calls PolicyHQ's verification tool, which checks every reference against the database. You receive a clear report: which citations verified, which are uncertain, and which were not found. You review, you decide, you file.

What is the Model Context Protocol?

MCP (Model Context Protocol) is an open standard created by Anthropic and now supported by OpenAI and Microsoft. It allows AI assistants to connect to external data sources and tools — similar to how a web browser connects to websites. PolicyHQ is an MCP server: a data source that AI assistants can query. When you connect PolicyHQ to your AI, you are giving it permission to access our database of UK law when it needs to. The AI sends a query, PolicyHQ returns data, and the AI incorporates it into its response to you. You remain in control at all times.

Governance & compliance

Full transparency. Full auditability.

Every query your AI makes to PolicyHQ is logged. Every search, every verification, every citation check — recorded with timestamps, the exact query text, and the exact results returned.

Your PolicyHQ dashboard gives you and your COLP complete visibility into how your firm's AI assistants are using legal research tools. This supports your obligations under the SRA Standards and Regulations to maintain appropriate governance, systems, and controls when using technology in legal practice.

Query log
Every search query with timestamp, AI platform used, and results returned.
Verification reports
Every document verification with per-citation status and source references.
Usage analytics
Queries per day, week, and month. Peak usage times. Most-queried topics.
API key management
Create, revoke, and label keys for different team members or AI platforms.
Export
Download query logs and verification reports as CSV for compliance records.
Alerts
Optional email alerts when not-found citations are detected in verification.

PolicyHQ does not store the content of your documents. Verification reports contain only the extracted citations and their verification status. Full document text is processed in memory and discarded after verification.

Pricing — simple. Predictable. No per-query billing.
