mcp-trino-python 0.4.0

A Model Context Protocol (MCP) connector for Trino, enabling seamless integration between MCP-compliant services and Trino query engine

MCP Trino Server

The MCP Trino Server is a Model Context Protocol (MCP) server that provides seamless integration with Trino and Iceberg, enabling advanced data exploration, querying, and table maintenance capabilities through a standard interface.

Use Cases

• Interactive data exploration and analysis in Trino
• Automated Iceberg table maintenance and optimization
• Building AI-powered tools that interact with Trino databases
• Executing and managing SQL queries with proper result formatting

Prerequisites

1. A running Trino server (or Docker Compose for local development)
2. Python 3.11 or higher
3. Docker (optional, for containerized deployment)

Installation

Running Trino Locally

The easiest way to get started is to use the included Docker Compose configuration to run Trino locally:

docker-compose up -d

This will start a Trino server on localhost:8080. You can now proceed with configuring the MCP server.

Usage with VS Code

For quick installation, you can add the following configuration to your VS Code settings. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open User Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

Note that the mcp key is not needed in the .vscode/mcp.json file.
