AI agents call search_conseil_etat 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 search_conseil_etat 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.

EXTRACTION DU TEXTE : les ids retournés (/Ariane_Web/AW_DCE/|XXXXXX) sont DÉSORMAIS exploitables directement par get_decision_text(id) (récupération live via le plugin Sinequa). ⚠️ COUVERTURE : cet index ArianeWeb (Sinequa) couvre MAL les arrêts anciens/fondateurs (avant ~1990). Si une recherche ici renvoie 0, NE PAS conclure que l'arrêt est absent de JusticeLibre : le bulk JADE (search_admin) couvre le CE depuis 1873 (Trompier-Gravier 1944, PGD, etc. inclus). Et si tu connais déjà l'id Légifrance CETATEXT… d'un arrêt, get_decision_text("CETATEXT…") le sort directement du bulk. Consigne de recherche : limiter les requêtes à 2-5 mots-clés distinctifs ; les requêtes en phrase complète retournent généralement zéro résultat. Args: query: mots-clés de recherche (ex : "référé liberté", "QPC 145") limit: nombre maximum de résultats (défaut 20) offset: décalage pour paginer (défaut 0). Réitérer avec offset=20, offset=40, etc. pour obtenir les pages suivantes.. 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 search_conseil_etat: 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.
search_conseil_etat 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 search_conseil_etat 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 search_conseil_etat. 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.
search_conseil_etat 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.
