What is ayunis-legal-mcp CLAUDE.md?

Project guidance for a legal-text search system that lets AI assistants find German laws using everyday language. It describes the backend, search database, and connection between the search service and AI tools.

Use it when developing, debugging, or onboarding someone to the German legal search system, including its API, AI-tool connection, and database.

It gives developers one place to understand how the system is organised and how its parts communicate. This reduces guesswork when changing or extending the project.

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

ayunis-legal-mcp CLAUDE.md scanned grade A with 1 finding 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 2mo 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.

Legal MCP - Architecture and Development Guide

Project Overview

Legal MCP is a semantic search system for German legal texts with two main components:

Store API (FastAPI) - Backend service with PostgreSQL + pgvector for storing and searching legal texts
MCP Server (FastMCP) - Model Context Protocol server that exposes legal search tools to AI assistants

Purpose: Enable AI assistants to semantically search German legal codes (BGB, StGB, GG, etc.) using natural language queries and retrieve specific legal sections.

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.
