mcp-eu-compliance: Instructions file for Codex

AGENTS.md

mcp-eu-compliance AGENTS.md is an instructions file for Codex, OpenCode from matematicsolutions/mcp-eu-compliance. It costs 1,322 tokens per session, scanned A, original, MIT.

A repository instruction file for an offline service that searches the full text of European Union digital and cybersecurity laws. AGENTS.md is a convention for recording rules that coding agents should follow in a project.

In plain words
What is it for?
Guiding work on an EU-law search and compliance service covering regulations such as GDPR, the AI Act, DORA, and NIS2.
Why use it?
It gives an agent the project’s purpose, legal scope, tool requirements, and strict rules for returning source citations. The offline database avoids relying on generated legal text during retrieval.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is matematicsolutions/mcp-eu-compliance's own configuration. It tells Codex and OpenCode how to work on mcp-eu-compliance itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-eu-compliance configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-eu-compliance AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AGENTS.md - mcp-eu-compliance

An agents.md standard file (Linux Foundation / Agentic AI Foundation) - canonical instructions for AI agents working with this repository.

Project purpose

An MCP (Model Context Protocol) server exposing an offline corpus of EU law (EUR-Lex, full text) in local SQLite FTS5, with compliance-oriented tools. Verbatim, zero-LLM in the retrieval path - snippets returned unchanged from the database, each with a CELEX id and EUR-Lex URL.

Scope (ADR-0022 + extension per WM decision 2026-07-04): 14 digital/data/cyber regulations - GDPR, AI Act, DORA, NIS2, eIDAS 2.0, CRA, DSA, DMA, Data Act, DGA, LED, ePrivacy, Cybersecurity Act, CER. All 14 have full text + applicability rules + evidence artifacts in the corpus (the complete set of 5 tools works).

The 6th connector in the MateMatic law family (mcp-saos, mcp-nsa, mcp-isap, mcp-krs, mcp-eu-sparql, mcp-eu-compliance (this one)). Complementary to mcp-eu-sparql: that one discovers acts live (SPARQL Cellar), this one provides verbatim text + offline compliance analysis.

MateMatic context (HARD CONSTRAINTS)

  • Every tool call MUST return structuredContent.citations with: regulation id, full name, CELEX, EUR-Lex URL, (optionally) article number, corpus snapshot.
  • Verbatim - text returned without model processing (zero-LLM). This is the grounding source (anti-hallucination).
  • Snapshot, not the authentic source - every response carries a disclaimer: the authentic version = Official Journal of the EU; verify in EUR-Lex.
  • Hard scope of 14 regulations - even though the database has 116 (snapshot 2026-07-04; the corpus grows, see db_metadata.regulations_count), the connector exposes only 14 (v1 scope). Filter in SCOPE.
  • Offline - zero network calls at runtime. Delegate freshness to mcp-eu-sparql (live).
  • Applicability rules are guidance, not a legal assessment (Art. 6 of the Patron Constitution, human-in-the-loop).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
