Common questions

Is Copilot Datagate safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 13 days ago, and the latest version (0.4.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

📘 DataGate — Secure AI-Ready Data Gateway

DataGate è un gateway headless, sicuro e policy-driven che espone basi dati a strumenti AI (come GitHub Copilot) in modo controllato, prevedibile e privo di SQL libero.

DataGate funge da intermediario tra un LLM e una base dati reale: non permette accesso diretto al database, non espone query arbitrarie, non consente operazioni di scrittura. È progettato per essere read-only, schema-aware, multi-database, e completamente LLM-safe.

🎯 Obiettivi principali

  • Accesso sicuro ai dati — read-only garantito tramite ruoli DB, policy engine e query builder controllato.
  • Astrazione del database — il modello non genera SQL: DataGate costruisce query sicure e validate.
  • Multi-database — può collegarsi a diverse basi dati di diverse applicazioni, come un DBeaver headless.
  • Policy engine — controllo granulare su tabelle, colonne, filtri, limiti e complessità delle operazioni.
  • Schema awareness — carica automaticamente lo schema del database e applica regole di sicurezza.
  • Concorrenza reale — architettura asincrona e sicura, ideale per richieste parallele da Copilot.
  • Metriche e audit — tracciamento di richieste, tempi, errori e limiti per debugging e osservabilità.
  • Profilazione performance — profilo latenza in-process (min/media/p50/p95/p99/max) per monitoraggio evolutivo delle performance.
  • Backend astratto — trait read-only comune per backend database, con implementazioni concrete per PostgreSQL, MySQL/MariaDB e SQLite.

🧩 Funzionalità principali

  • Query builder controllato — operazioni semantiche come select, search, aggregate, con validazione automatica.
  • MCP `select` tipizzato — contratto JSON, esecuzione read-only con righe JSON, policy, audit ed errori sanitizzati; il transport MCP resta lo step successivo.
  • MCP `search` tipizzato — ricerca semantica con ILIKE su colonne consentite, query parametrizzate, policy/rate-limit/metriche/audit e output limit server-side.
  • MCP `aggregate` tipizzato — count, sum, avg, min e max su colonne consentite, con filtri parametrizzati e senza supporto a SQL libero o GROUP BY.
  • API MCP versionata — descriptor stabile per versione API e tool disponibili.
  • Transport MCP stdio — handshake, discovery e chiamate select, search e aggregate sopra il percorso policy-safe.
  • Filtri avanzati — supporto a pattern (LIKE/ILIKE), range (BETWEEN) e full-text (to_tsvector + plainto_tsquery) sempre parametrizzati e validati da policy.
  • Catalogo schema controllato — introspezione policy-filtered di tabelle, viste, indici, vincoli (PK/FK/UNIQUE/CHECK/EXCLUSION), trigger, funzioni, procedure e sequenze; definizioni DDL solo quando sicure.
  • Rate limiting — protezione contro loop del modello e query troppo pesanti.
  • Limiti di output — risposte sempre contenute, sicure e strutturate.
  • Errori deterministici — nessun leak di schema, nessun SQL esposto, nessun stack trace.
  • Errori strutturati — envelope stabile con codice, messaggio generico e indicazione retryable.
  • Configurazione esterna — file TOML per policy, limiti e profili nominati (dev/staging/prod).
  • Hardening input MCP — validazione request_id, limiti su payload testuali e cardinalità per ridurre superfici DoS/input abuse.
  • Policy dinamica — la policy attiva può essere sostituita atomicamente, anche ricaricandola da TOML, senza ricreare i tool MCP.

DataGate non espone una funzione MCP di query SQL libera: l'agente invia esclusivamente parametri strutturati, validati contro schema e policy prima della costruzione della query parametrizzata.

Gli errori pubblici usano i codici invalid_request, policy_denied, backend_unavailable e internal_error. SQL, stack trace, password, valori dei filtri e nomi di oggetti non autorizzati non attraversano il confine MCP.

Configurazione PostgreSQL

Le credenziali PostgreSQL non vengono salvate nei file di configurazione o nel codice. Il servizio legge la connessione dall'ambiente runtime:

  • modalità compatta: DB_URL
  • modalità a componenti: DB_HOST, DB_PORT (default 5432), DB_USER, DB_PASSWORD, DB_NAME
  • opzioni PostgreSQL: DB_OPTIONS, nel formato key=value&key=value
  • pool: DB_MAX_CONNECTIONS e DB_ACQUIRE_TIMEOUT_SECS
Configurazione SQLite

Per usare SQLite in modalità read-only, configura una delle due varianti:

  • URL completo: SQLITE_URL
  • path file: SQLITE_PATH

Opzioni pool SQLite:

  • SQLITE_MAX_CONNECTIONS
  • SQLITE_ACQUIRE_TIMEOUT_SECS
Configurazione MySQL/MariaDB

Per usare MySQL o MariaDB in modalità read-only, configura una delle due varianti:

  • URL completo: MYSQL_URL
  • modalità a componenti: MYSQL_HOST, MYSQL_PORT (default 3306), MYSQL_USER, MYSQL_PASSWORD, MYSQL_DATABASE

Opzioni pool MySQL/MariaDB:

  • MYSQL_MAX_CONNECTIONS
  • MYSQL_ACQUIRE_TIMEOUT_SECS
Selezione backend multi-database

Per scegliere esplicitamente quale backend attivare, imposta DATAGATE_BACKEND:

  • auto (default): precedenza postgres -> mysql -> sqlite
  • postgres
  • mysql (o mariadb)
  • sqlite

Quando DATAGATE_BACKEND è impostato a un backend specifico, DataGate richiede la relativa configurazione ambiente; in caso contrario termina con errore esplicito.

Precedenza backend in bootstrap:

  1. PostgreSQL
  2. MySQL/MariaDB
  3. SQLite

Il primo backend configurato nella lista viene attivato.

Il rate limiting server-side opzionale usa RATE_LIMIT_REQUESTS e RATE_LIMIT_WINDOW_SECS. Il limite è applicato per request_id prima di policy, query builder e database; richieste oltre soglia ricevono rate_limited e non generano SQL.

Il query builder applica anche un budget massimo configurabile nella policy tramite max_query_complexity: ogni colonna costa 1 e ogni filtro costa 2. Le richieste oltre budget vengono rifiutate prima di generare SQL.

La risposta select è soggetta anche a max_output_bytes nella policy: se il payload JSON finale supera il limite, DataGate rifiuta la richiesta con errore di policy senza esporre SQL o dettagli interni.

Il layer metriche registra anche contatori e latenza lato server per il tool select: richieste totali/accettate/rifiutate, errori backend, p95 latenza in memoria e snapshot del pool PostgreSQL (size, idle).

Il logging applicativo supporta due formati:

  • LOG_FORMAT=pretty (default)
  • LOG_FORMAT=json (strutturato, adatto a log collector)

Il livello minimo dei log può essere configurato con LOG_LEVEL (trace|debug|info|warn|error) oppure tramite RUST_LOG.

Se DB_URL è presente ha precedenza sui componenti. Il ruolo PostgreSQL deve avere solo permessi di lettura; inoltre ogni connessione imposta default_transaction_read_only = on.

Il profilo attivo si seleziona con profile = "dev" e può definire la policy in [profiles.dev.policy]. Se non sono presenti profili nominati, resta supportata la forma legacy [policy]. Un profilo dichiarato ma inesistente attiva una policy deny-all, senza avviare operazioni sul database.

Le release pubblicate includono binari per Linux x64/ARM64, Windows x64/ARM64 e macOS Intel/Apple Silicon, con archivi nominati per piattaforma e file SHA256SUMS-* per la verifica degli artifact.

🛡️ Perché DataGate?

Gli LLM non devono parlare direttamente ai database. Serve un layer sicuro, prevedibile, controllato, auditabile, estensibile e multi-applicazione. DataGate è questo layer.

🔧 Tecnologie

  • Linguaggio: Rust
  • Database: PostgreSQL, MySQL/MariaDB e SQLite (oggi), altri DB domani
  • Protocollo: MCP (Model Context Protocol)
  • Architettura: asincrona, policy-driven, schema-aware

🚀 Stato del progetto

DataGate è in fase di progettazione. Il repository contiene la struttura iniziale, la documentazione e la roadmap tecnica.

🧪 Test integrazione multi-backend

I test di integrazione backend usano variabili ambiente opzionali:

  • DATAGATE_TEST_POSTGRES_URL
  • DATAGATE_TEST_MYSQL_URL

Quando una variabile è presente, il relativo test verifica che il backend read-only esegua SELECT controllate e rifiuti statement di scrittura. Se la variabile non è presente, il test viene saltato senza errore.

Documentazione completa:

Per l'avvio da VS Code con MCP:

  • il transport locale di default è stdio
  • i template mcp.json per stdio locale sono in docs/mcp-tools.md e docs/configuration.md
  • HTTP remoto è fuori dal default 1.0 e richiede una decisione di sicurezza dedicata

📍 Roadmap (sintesi)

  • Definizione del policy engine
  • Implementazione del query builder controllato (select parametrizzato)
  • Connessione read-only garantita
  • Schema awareness automatica (catalogo interno PostgreSQL)
  • Audit log foundation (JSONL via AUDIT_LOG_PATH)
  • Tool MCP (select, search, aggregate)
  • Supporto multi-database (PostgreSQL, MySQL/MariaDB, SQLite)
  • Enterprise layer iniziale (osservabilità, hardening, policy dinamica)
  • Stabilità API MCP (descriptor versionato; transport stdio)
  • Transport MCP stdio
  • Benchmark
  • Hardening finale
  • Versione 1.0 candidate
