Overview

AI-generated overview

Lets an assistant search 112M+ Brazilian court decisions and run jurimetric analyses such as outcome prediction and citation checks.

What it does
RAGJur exposes 14 tools over a remote MCP server for Brazilian legal research. Tools include full-text search of court decisions with filters by tribunal, class and date, semantic similarity search, topic overviews with outcome rates, divergence between panels, jurisprudential evolution, statistical outcome prediction, litigation-time statistics, judge and panel profiles, thematic clustering, citation verification, grounded legal Q&A, and drafting of procedural documents based on real precedents. Coverage spans STF, STJ, TST, TSE, TCU, federal, state, labor, electoral and audit courts.
When to use it
Useful for Brazilian legal research and jurimetric analysis: finding precedents, checking whether citations exist, comparing panels, estimating outcomes or timelines, and drafting documents grounded in retrieved decisions.
Requirements
A remote streamable HTTP endpoint at mcp.ragjur.ai; no local runtime or package. Authentication is OAuth 2.1 (PKCE S256, scope ragjur:read) or, as an optional alternative, a RAGJur API key sent in the x-api-key header. API keys come with a RAGJur subscription. Network access to the remote server is required.
Before you install
The x-api-key header carries a RAGJur API key (rj_…) created in the RAGJur account panel; treat it as a secret. Queries are sent to the third-party server mcp.ragjur.ai, which searches its corpus and returns results; the server is described as stateless with a 30-minute session TTL and data processed in Brazil. Drafting and verification tools produce legal content that should be reviewed by a qualified professional.

RAGJur — Claude Plugin

Brazilian legal RAG for Claude — search 112M+ court decisions from 90+ Brazilian tribunals.

This repository contains the Claude plugin manifest for RAGJur. The plugin connects Claude to the RAGJur MCP server (remote, streamable HTTP) at https://mcp.ragjur.ai/mcp.

Install

In Claude Code:

/plugin marketplace add btechbrasil/ragjur-mcp/plugin install ragjur@btechbrasil

During installation, Claude asks for your RAGJur API Key (stored as a sensitive user config — it is never read from your machine without asking). API keys are included with RAGJur subscriptions: ragjur.ai.

What you get — 14 tools

Example prompts

  • "Busque os acórdãos mais recentes do STJ sobre busca e apreensão em alienação fiduciária"
  • "Qual a taxa de provimento de recursos sobre dano moral no TJSP? Há divergência entre as câmaras?"
  • "Verifique se as citações desta peça existem"
  • "Redija uma contestação sobre despejo por falta de pagamento, lado réu, TJMG"

How it works

The plugin registers one remote MCP server (HTTP transport). Your queries are sent to mcp.ragjur.ai, which searches the Elasticsearch corpus and returns grounded results. The server is stateless — no conversation or query data is persisted after the session ends.

Privacy & data

  • Stateless MCP server (30-minute session TTL, nothing stored)
  • Data processed in Brazil (Alibaba Cloud São Paulo region)
  • LGPD-compliant: ragjur.ai/lgpd
  • Privacy policy: ragjur.ai/privacidade
