Dataring-engineering/mcp-server-trino

This repository provides an MCP (Model-Control-Protocol) server that allows you to list and query tables via Trino using Python.

Overview

• MCP: MCP is a protocol for bridging AI models, data, and tools. This example MCP server provides:
  • A list of Trino tables as MCP resources
  • Ability to read table contents through MCP
  • A tool for executing arbitrary SQL queries against Trino
• Trino: A fast, distributed SQL query engine for big data analytics. This server makes use of Trino’s Python client (trino.dbapi) to connect to a Trino host, catalog, and schema.

Requirements

• Python 3.9+ (or a version compatible with mcp, trino, and asyncio)
• trino (the Python driver for Trino)
• mcp (the Model-Control-Protocol Python library)

Configuration

The server reads Trino connection details from environment variables:

Variable	Description	Default
TRINO_HOST	Trino server hostname or IP	localhost
TRINO_PORT	Trino server port	8080
TRINO_USER	Trino user name	required
TRINO_PASSWORD	Trino password (optional, depends on your authentication setup)	(empty)
TRINO_CATALOG	Default catalog to use (e.g., hive, tpch, postgresql, etc.)	required
TRINO_SCHEMA	Default schema to use (e.g., default, public, etc.)	required
