HEU Legal MCP Server

MCP server (Model Context Protocol) che collega l'API HEU Legal a Claude e a qualsiasi client MCP. Gestisce l'intero ciclo di vita dei documenti con firma elettronica (valida in 180+ paesi) direttamente in conversazione: dalla creazione all'invio in firma, dal sollecito al download del fascicolo legale completo.

Cosa puoi fare

Due famiglie di oggetti:

  • Documenti nativi HEU — creati con l'editor in-app della piattaforma (ID a forma di UUID, es. 5135e7b2-196b-...).
  • PDF caricati — file PDF con firmatari e campi firma posizionati sopra (ID numerici, es. 68).

Requisiti

  • Python ≥ 3.10
  • API key HEU Legal — nella UI: Profile → API Keys → Generate API Key (richiede subscription Enterprise; massimo 2 chiavi attive)
  • Per i flussi da template: almeno un template creato sulla piattaforma (oppure crealo via API con createpdftemplate)

Installazione

Da PyPI:

pip install heu-mcp

Da sorgenti:

git clone https://github.com/heulegal/heu-mcp.git
cd heu-mcp
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Configurazione

Claude Desktop

Modifica ~/Library/Application Support/Claude/claudedesktopconfig.json (macOS) o %APPDATA%\Claude\claudedesktopconfig.json (Windows):

{
  "mcpServers": {
    "heu": {
      "command": "heu-mcp",
      "args": [],
      "env": {
        "HEU_API_KEY": "la_tua_api_key_qui"
      }
    }
  }
}

Se installato da sorgenti con venv:

{
  "mcpServers": {
    "heu": {
      "command": "/path/assoluto/heu-mcp/venv/bin/python",
      "args": ["/path/assoluto/heu-mcp/server.py"],
      "env": {
        "HEU_API_KEY": "la_tua_api_key_qui"
      }
    }
  }
}

Riavvia Claude Desktop dopo la modifica.
