Trino MCP Server in Go

A high-performance Model Context Protocol (MCP) server for Trino implemented in Go. This project enables AI assistants to seamlessly interact with Trino's distributed SQL query engine through standardized MCP tools.

Overview

This project implements a Model Context Protocol (MCP) server for Trino in Go. It enables AI assistants to access Trino's distributed SQL query engine through standardized MCP tools.

Trino (formerly PrestoSQL) is a powerful distributed SQL query engine designed for fast analytics on large datasets.
