Generate code with real court data using this MCP Server

The `search_process_by_number` tool lets Cursor fetch actual Brazilian court records while you write your legal tech applications. Instead of mock data, your editor pulls live JSON payloads directly into your active workspace. Your agent reads the live structure of the judicial response to write accurate parsers. This eliminates the guesswork of coding against outdated API documentation.

Run advanced Elasticsearch queries in Cursor Agent mode

The `search_processes_advanced` tool connects Cursor directly to the Datajud search cluster. You ask the editor to find specific case patterns, and it writes and executes the query for you. The results inject directly into your open files. You can build database seeds or test suites using real Brazilian lawsuit data in seconds.

Classify litigation by court organ

The `search_processes_by_class_and_organ` tool retrieves cases matching specific CNJ tables of procedural classes. You can target regional federal courts or state tribunals with precise codes. This allows Cursor to help you map out data pipelines for legal analytics. You get clean, categorized responses that match the official Brazilian judicial branch standards.
