+### Enterprise Features
+
+These features require an AxonFlow Enterprise license:
+

+    .repoName("your-repo")
+    .prNumber(123)
+    .checkTypes(List.of("security", "style", "performance"))
+    .build());
+
+// Cost Controls - Budget management for LLM usage
+Budget budget = client.getBudget("team-engineering");
+// Returns: Budget{limit=1000.00, used=234.56, remaining=765.44}
+
+// MCP Policy Enforcement - Automatic PII redaction in connector responses
+MCPQueryResponse resp = client.queryConnector(query);
+// resp.getPolicyInfo().isRedacted() = true
+// resp.getPolicyInfo().getRedactedFields() = ["ssn", "credit_card"]
