MCP (Model Context Protocol) server for Legalis — Brazilian legal document AI for attorneys.

Connect Claude (or any MCP-compatible client) to your Legalis account and interact with cases, generate legal documents, search legislation, and more using natural language.

---

Quick start

1. Install

pip install legalis-mcp
# or with uv:
uv tool install legalis-mcp

2. Authenticate

legalis-mcp auth

This opens your browser. Log in to Legalis normally — tokens are saved to ~/.legalis/credentials.json (owner-readable only).

3. Configure Claude

Add to your Claude configuration (~/.claude/claude_desktop_config.json for Claude Desktop, or claude_code_config.json for Claude Code):

{
  "mcpServers": {
    "legalis": {
      "command": "legalis-mcp",
      "args": ["serve"]
    }
  }
}

4. Use

In Claude, try:

• "Liste meus casos no Legalis"
• "Crie um caso de rescisão indireta para João Silva"
• "Gere a seção de fundamentos jurídicos da peça X do caso Y"
• "Pesquise legislação trabalhista sobre justa causa"
• "Quantas gerações ainda tenho disponíveis este mês?"

Security

• Credentials are stored in ~/.legalis/credentials.json with 600 permissions (owner read/write only).
• The OAuth redirect is restricted to http://localhost — open-redirect attacks are blocked at the backend.
• Tokens are never stored in the MCP configuration file.
• All API calls go through the existing Legalis backend — RBAC, rate limiting, and quotas apply normally.
