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.

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

| GDPR | 32016R0679 |
| Digital Services Act (DSA) | 32022R2065 |
| Digital Markets Act (DMA) | 32022R1925 |
| NIS2 | 32022L2555 |
| Data Act | 32023R2854 |
| Cyber Resilience Act (CRA) | 32024R2847 |
| DORA | 32022R2554 |

EDPB guidelines are next. Need a corpus that isn't here? New corpora are a matter of hours — ask at capy@acquislaw.com.
Five read-only tools:
| Tool | What |
|---|---|
search_eu_law | Semantic search over the corpus → ranked verbatim provisions with citations. |
get_provision | Exact lookup by legal anchor — act: "AI Act", article: "6", paragraph: "1", point: "a" (also annex, recital). |
get_act_status | An act's CELEX number(s), latest consolidation date, in-force info and coverage. |
list_versions | Every stored version of an article with validity windows ("what did it say before the amendment?"). |
verify_fragment | Recomputes the content hash and reports the ed25519 signing provenance of any returned citation. |
Acquis is a remote server. Authentication is OAuth 2.1 (an account is created in-flow, with a 7-day Pro trial, no card).
Add a custom connector pointing at the remote URL:
In claude.ai → Settings → Connectors → Add custom connector, paste the URL and complete the sign-in screen.
Clients that speak stdio can reach the remote server through the
mcp-remote adapter, which also
carries the OAuth flow:
/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:
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.
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.

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.
