Perplexity

Fetch precise legal records on demand

The `search_process_by_number` tool retrieves complete case histories from specific Brazilian regional courts. Cline uses this to look up process details, extract active parties, and parse complex procedural steps. Since Cline can write files, it takes the output of this tool and saves it as clean JSON or markdown files in your project directory. You don't have to copy-paste raw API payloads from a browser window anymore.

Run advanced Elasticsearch queries via this MCP Server

The `search_processes_advanced` tool gives Cline direct access to the Datajud Elasticsearch database. This allows your agent to run deep, filtered searches across millions of Brazilian legal records using complex criteria. You can instruct Cline to write a local script that parses these search results. It will run the tool, write the script, execute it in your terminal, and display a clean chart of case distributions.

Map court organs and procedural classes

The `search_processes_by_class_and_organ` tool filters legal cases by their designated class and the specific court organ in charge. This helps your agent isolate specific legal subjects within a chosen jurisdiction. If you need to audit how a specific court handles a certain class of lawsuit, Cline can query the data, analyze the distribution, and build an HTML dashboard to visualize the findings.

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

Open the Cline sidebar and click the MCP Servers icon to add the remote server URL. Alternatively, paste the server configuration directly into your `cline_mcp_settings.json` file to let the agent auto-discover the tools.

No, the MCP Server handles the routing internally. When Cline calls the search tool, it passes the target court identifier like TJSP or TRF1 as a parameter, keeping your workspace configuration clean.

Yes, because Cline can write and execute local scripts. You can ask it to run a daily task that queries the Datajud API and outputs a summary of updates to your workspace.

Cline inspects the error returned by the advanced search tool. It then reformats the Elasticsearch JSON query automatically and retries the request until it gets a valid response.

Your search queries and retrieved Brazilian legal records travel through an isolated, zero-trust V8 sandbox. No data is cached on external servers, keeping your sensitive legal research strictly between Cline and the official Datajud endpoints.
