README

Acquis — Verified EU Law for AI assistants

Acquis gives Claude, ChatGPT and any MCP-enabled assistant exact, verifiable access to EU digital regulation. Instead of paraphrasing from training data, your assistant quotes the verbatim provision of the current consolidation — with the full citation (act, article, paragraph, point), its in-force status, the consolidation date and a deep link to EUR-Lex, so you can check every claim yourself.

The verbatim legal text is rendered from a signed corpus — it is not written by the model. Every fragment is content-hashed and ed25519-signed at ingestion, and any citation can be cryptographically verified.

This repository documents the public MCP endpoint. The hosted service, its source code and its data products are proprietary and governed by the terms at acquislaw.com — only the contents of this repository are MIT-licensed (see LICENSE).

Corpus

The EU digital rulebook, all consolidated and updated by daily sweeps of the official EUR-Lex/CELLAR catalog (new consolidations, corrigenda, status changes):

ActCELEX
AI Act (applies from 2 August 2026 — Art. 113 staggers the rest)32024R1689
GDPR32016R0679
Digital Services Act (DSA)32022R2065
Digital Markets Act (DMA)32022R1925

Tools

Five read-only tools:

ToolWhat
search_eu_lawSemantic search over the corpus → ranked verbatim provisions with citations.
get_provisionExact lookup by legal anchor — act: "AI Act", article: "6", paragraph: "1", point: "a" (also annex, recital).
get_act_statusAn act's CELEX number(s), latest consolidation date, in-force info and coverage.
list_versionsEvery stored version of an article with validity windows ("what did it say before the amendment?").
verify_fragmentRecomputes the content hash and reports the ed25519 signing provenance of any returned citation.

Install

Acquis is a remote server. Authentication is OAuth 2.1 (an account is created in-flow, with a 7-day Pro trial, no card).

Claude (Desktop / claude.ai / Code)

Add a custom connector pointing at the remote URL:

https://api.acquislaw.com/mcp

In claude.ai → Settings → Connectors → Add custom connector, paste the URL and complete the sign-in screen.

Cursor, Cline, VS Code and other MCP clients (stdio via the shim)

Clients that speak stdio can reach the remote server through the mcp-remote adapter, which also carries the OAuth flow:

json
{  "mcpServers": {    "acquis": {      "command": "npx",      "args": ["-y", "mcp-remote", "https://api.acquislaw.com/mcp"]    }  }}

Inspecting the tools without an account

/mcp is OAuth-protected, so an unauthenticated probe gets a 401 (that challenge is what starts the sign-in flow). To let any client or directory read the tool catalog without an account, there is a public introspection endpoint:

https://api.acquislaw.com/mcp/public

It advertises the same five tool definitions and returns no legal content — every call points you back at the real endpoint. Use it to inspect the server; use /mcp for answers.

Example

Prompt: "What does Article 6 of the AI Act say about high-risk classification? Then verify that citation."

get_provision(act: "AI Act", article: "6") returns the eight paragraphs of Article 6 verbatim, each with its EUR-Lex link; verify_fragment then recomputes the content hash and confirms the ed25519 signing provenance.

Not legal advice

Acquis returns official sources verbatim with citations. It is a retrieval layer with provenance — not legal advice. Built by Capybara Labs on HIVE, our verifiable knowledge engine.
