Overview

This project implements a Model Context Protocol (MCP) server designed specifically to interact with Amazon Redshift databases.

It bridges the gap between Large Language Models (LLMs) or AI assistants (like those in Claude, Cursor, or custom applications) and your Redshift data warehouse, enabling secure, standardized data access and interaction. This allows users to query data, understand database structure, and monitoring/diagnostic operations using natural language or AI-driven prompts.

This server is for developers, data analysts, or teams looking to integrate LLM capabilities directly with their Amazon Redshift data environment in a structured and secure manner.

Features

✨ Secure Redshift Connection (via Data API): Connects to your Amazon Redshift cluster using the AWS Redshift Data API via Boto3, leveraging AWS Secrets Manager for credentials managed securely via environment variables.
🔍 Schema Discovery: Exposes MCP resources for listing schemas and tables within a specified schema.
📊 Metadata & Statistics: Provides a tool (handle_inspect_table) to gather detailed table metadata, statistics (like size, row counts, skew, stats staleness), and maintenance status.
📝 Read-Only Query Execution: Offers a secure MCP tool (handle_execute_ad_hoc_query) to execute arbitrary SELECT queries against the Redshift database, enabling data retrieval based on LLM requests.
📈 Query Performance Analysis: Includes a tool (handle_diagnose_query_performance) to retrieve and analyze the execution plan, metrics, and historical data for a specific query ID.
🔍 Table Inspection: Provides a tool (handle_inspect_table) to perform a comprehensive inspection of a table, including design, storage, health, and usage.
🩺 Cluster Health Check: Offers a tool (handle_check_cluster_health) to perform a basic or full health assessment of the cluster using various diagnostic queries.
🔒 Lock Diagnosis: Provides a tool (handle_diagnose_locks) to identify and report on current lock contention and blocking sessions.
📊 Workload Monitoring: Includes a tool (handle_monitor_workload) to analyze cluster workload patterns over a time window, covering WLM, top queries, and resource usage.
📝 DDL Retrieval: Offers a tool (handle_get_table_definition) to retrieve the SHOW TABLE output (DDL) for a specified table.
🛡️ Input Sanitization: Utilizes parameterized queries via the Boto3 Redshift Data API client where applicable to mitigate SQL injection risks.
🧩 Standardized MCP Interface: Adheres to the Model Context Protocol specification for seamless integration with compatible clients (e.g., Claude Desktop, Cursor IDE, custom applications).

Prerequisites

Software:
Python 3.10+
uv (recommended package manager) or pip

Infrastructure & Access:

Access to an Amazon Redshift cluster.
An AWS account with permissions to use the Redshift Data API (redshift-data:) and access the specified Secrets Manager secret (secretsmanager:GetSecretValue).
A Redshift user account whose credentials are stored in AWS Secrets Manager. This user needs the necessary permissions within Redshift to perform the actions enabled by this server (e.g., CONNECT to the database, SELECT on target tables, SELECT on relevant system views like pg_class, pg_namespace, svv_all_schemas, svv_tables, svv_table_info). Using a role with the principle of least privilege is strongly recommended. See Security Considerations.

Credentials:

Your Redshift connection details are managed via AWS Secrets Manager, and the server connects using the Redshift Data API. You need:

The Redshift cluster identifier.
The database name within the cluster.
The ARN of the AWS Secrets Manager secret containing the database credentials (username and password).
The AWS region where the cluster and secret reside.

• Optionally, an AWS profile name if not using default credentials/region.

These details will be configured via environment variables as detailed in the Configuration section.

Installation

Install from PyPI (Recommended)

The easiest way to install the Redshift Utils MCP Server is directly from PyPI:

``bash
