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.

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.

- Stateless MCP server (30-minute session TTL, nothing stored)
