The MCP Trino Server is a [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction)
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

### Installing via Smithery

To install MCP Trino Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@alaturqua/mcp-trino-python):

```bash
npx -y @smithery/cli install @alaturqua/mcp-trino-python --client claude
```

### Running Trino Locally

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

```bash
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.

```json
{
  "mcp": {
    "servers": {
      "trino": {
        "command": "docker",
        "args": ["run", "--rm", "ghcr.io/alaturqua/mcp-trino-python:latest"],
        "env": {
          "TRINO_HOST": "${input:trino_host}",
          "TRINO_PORT": "${input:trino_port}",
          "TRINO_USER": "${input:trino_user}",
          "TRINO_PASSWORD": "${input:trino_password}",
          "TRINO_HTTP_SCHEME": "${input:trino_http_scheme}",
          "TRINO_CATALOG": "${input:trino_catalog}",
          "TRINO_SCHEMA": "${input:trino_schema}"
        }
      }
    }
  }
}
```

### Usage with Claude Desktop

Add the following configuration to your Claude Desktop settings:

```json
{
  "mcpServers": {
    "trino": {
      "command": "python",
      "args": ["./src/server.py"],
      "env": {
        "TRINO_HOST": "your-trino-host",
        "TRINO_PORT": "8080",
        "TRINO_USER": "trino"
      }
    }
  }
}
```
