Perplexity

Pull specific case details inside Windsurf

The `search_process_by_number` tool lets your agent fetch the exact status, history, and parties of any Brazilian lawsuit using its standard CNJ format. You just feed Cascade a process number, and it targets the right regional court API, like the TJSP or TRF1, to pull the raw record. Cascade doesn't stop at just fetching the data. Because it chains actions, it can take the output from this query, extract the legal representatives, and immediately start drafting a case summary or court response in your editor.

Build complex legal reports using an MCP Server

The `search_processes_advanced` tool exposes the full power of Elasticsearch queries against the Datajud database directly to your editor. Instead of writing raw JSON queries by hand, you describe what you need to Cascade, and it structures the search parameters for you. This setup lets you discover patterns across thousands of filings. Cascade can analyze the returns, group them by judge or decision type, and generate clean markdown reports right in your workspace.

Classify judicial trends automatically

The `search_processes_by_class_and_organ` tool queries cases based on their specific procedural class and the court organ overseeing them. It gives your AI client the ability to scan entire jurisdictions for specific types of litigation. You can tell Cascade to monitor a specific court organ for new filings in a particular class. It runs the query, compares it to your local files, and highlights new legal risks or precedents without you writing any custom scraper code.

Common questions about CNJ (Datajud API Pública) MCP in Windsurf

Add the MCP Server configuration to your `~/.codeium/windsurf/mcp_config.json` file under the `mcpServers` key, or use the Cascade settings UI. Once you click refresh, Cascade instantly registers the three search tools and can use them in any conversation.

Yes. Cascade reads your environment variables or configuration blocks to pass the correct credentials, such as those for TRF1 or TJSP, when calling the tools. This ensures your queries don't get blocked by the individual court gateways.

When you ask for a case history, Cascade uses the primary search tool first. If it needs more context, it automatically triggers related queries to find associated cases in the same court without waiting for your next prompt.

You can. The advanced query tool lets you run broad Elasticsearch filters across different regional databases, and the agent compiles the results into a single view.

Vinkius hosts the connection in a secure, ephemeral sandbox that never stores the Brazilian judicial process data or court credentials. All search queries pass directly to the public Datajud API and return straight to your local Windsurf session.
