What is the CNJ (Datajud API Pública) MCP Server?
Connect to the CNJ Datajud Public API to perform deep searches across the Brazilian judicial system. This server allows AI agents to retrieve detailed metadata about lawsuits, court movements, and procedural history directly from the official national database.
What you can do
- Search by CNJ Number — Retrieve full details of a specific lawsuit using its unique unformatted numbering and the target court alias.
- Class & Organ Filtering — Find processes categorized by their Procedural Class (TPU) and specific Court Organ codes.
- Advanced Elasticsearch Queries — Execute complex searches using the full power of Elasticsearch Query DSL to filter by dates, parties, or specific metadata fields.
- Court Coverage — Access data from various courts including TRFs, TJs, TST, and more via their respective API aliases.
How it works
- Subscribe to this server
- Enter your CNJ Datajud API Key
- Start querying the Brazilian judicial database from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Legal Professionals — Quickly check the status and history of lawsuits without manual portal navigation.
- Compliance Teams — Automate background checks and legal risk assessments using official government data.
- Researchers & Analysts — Perform bulk queries and advanced data extraction for legal statistics and trends.

Frequently asked questions
How do I find a process if I only have the CNJ number?
Use the search_process_by_number tool. You will need the unformatted digits of the process and the specific court alias (e.g., api_publica_tjsp for São Paulo State Court).
Can I list multiple processes from a specific court organ?
Yes, use search_processes_by_class_and_organ. Provide the court alias, the procedural class code, and the organ code. You can also control the result size and use pagination.
What is the 'Advanced Search' tool for?
The search_processes_advanced tool allows you to send a raw Elasticsearch query body. This is useful for complex filtering that isn't covered by standard search tools, such as filtering by specific dates or nested metadata.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
