AI agents call get_law_article to retrieve information from Justicelibre without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_law_article only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Renvoie le texte d'un article de loi à une date donnée (ou version actuelle si date vide). Particularité justicelibre : quand une décision de 1992 cite l'article 1128 du Code civil, l'article a été totalement réécrit en 2016. Avec ce tool on récupère le texte tel qu'il existait en 1992 (l'ancienne version napoléonienne), pas le texte actuel. Codes supportés (22) : CC, CP, CPC, CPP, CT, CSP, CJA, CGCT, CRPA, CPI, CASF, CMF, C.com, C.cons, C.éduc, CU, C.env, CR, CGI, CESEDA, CSS, CCH. Args: code: code court (ex : "CC" pour Code civil, "CT" pour Code du travail) num: numéro de l'article (ex : "1128", "L1152-1", "132-1") date: date ISO YYYY-MM-DD (optionnel — si absent, version en vigueur). Utiliser la date de la décision citante pour obtenir la version contemporaine de la citation. Returns: dict avec legiarti, num, code, texte, etat (VIGUEUR/MODIFIE/ABROGE), date_debut, date_fin, nota. Plus un champ note si la version retournée n'est pas celle demandée.. It is categorised as a Read tool in the Justicelibre MCP Server, which means it retrieves data without modifying state.
Register the Justicelibre MCP server in PolicyLayer and add a rule for get_law_article: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Justicelibre. Nothing to install.
get_law_article is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_law_article rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_law_article. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_law_article is provided by the Justicelibre MCP server (https://justicelibre.org/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
