Common questions
Is Acquis safe?
It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, sync. labs

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.

Corpus
The EU digital rulebook, all consolidated and updated by daily sweeps of the official EUR-Lex/CELLAR catalog (new consolidations, corrigenda, status changes):
| Act | CELEX |
|---|---|
| AI Act (applies from 2 August 2026 — Art. 113 staggers the rest) | 32024R1689 |
| GDPR | 32016R0679 |
| Digital Services Act (DSA) | 32022R2065 |
| Digital Markets Act (DMA) | 32022R1925 |
| NIS2 | 32022L2555 |
| Data Act | 32023R2854 |
| Cyber Resilience Act (CRA) | 32024R2847 |
| DORA | 32022R2554 |
| eIDAS 2 | 32024R1183 |
| Product Liability Directive | 32024L2853 |
| Data Governance Act | 32022R0868 |

Tools
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. |
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/mcpIn 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:
{"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/publicIt 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.
