Security Report
Legalithm is a well-architected EU AI Act compliance tool with strong security fundamentals. The offline-first MCP server has no authentication requirements (by design), no hardcoded secrets, proper input validation with negation-aware pattern matching, and appropriate permission scoping. Code quality is high with comprehensive test coverage. Minor findings relate to broad exception handling and informational logging practices, which do not significantly impact security posture. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue (1 critical, 0 high severity).

Legalithm — EU AI Act compliance in your coding loop
Shipping an AI feature to EU users? The Act applies — Article 50 transparency from Aug 2026, high-risk obligations from Dec 2027. Catch it where you code, in seconds. Free, open-source, offline.
Quickstart
npx legalithm setup # wires Claude Code + Cursor (hooks, editor rule, MCP config)
npx legalithm init # writes a dated, cited compliance/legalithm.json
npx legalithm check # re-verify; non-zero exit on drift (for CI)
Three surfaces
- Editor — an offline MCP server (
legalithm-mcp-server) exposing 4 tools (classify,explain_obligation,generate_disclosure,check_record). No API key, no network. - Repo —
legalithm initwrites a dated, citedcompliance/legalithm.jsonthat records your AI system's risk tier and the obligations behind it. - CI —
legalithm checkand the GitHub Action fail the build when the committed record drifts — because your app changed or the law changed under you.
MCP config
Add the offline server to Claude Code or Cursor:
{
"mcpServers": {
"legalithm": {
"command": "npx",

Honest framing
A cited starting point that tells you when to get a human — not legal advice. When unsure, it flags the result for review instead of guessing. Every output is checked against Regulation (EU) 2024/1689; it is not a certification.
