Overview

What is Amazon S3 MCP Server by CData?

Amazon S3 MCP Server by CData is a read-only Model Context Protocol server that enables large language models to query live Amazon S3 data through natural language. It wraps the CData JDBC Driver for Amazon S3, exposing S3 objects as relational SQL tables, and is intended for AI clients such as Claude Desktop.

How to use Amazon S3 MCP Server by CData?

Clone the repository, build with mvn clean install, install and license the CData JDBC Driver for Amazon S3, then configure a .prp file with your JDBC connection string. Add the server to your Claude Desktop config file (claude_desktop_config.json) and restart the client. The server communicates over stdio and must run on the same machine as the client.

Key features of Amazon S3 MCP Server by CData

  • Read-only access to Amazon S3 data as relational tables.
  • Natural language querying via LLMs, no SQL required.
  • Tools to list tables, list columns, and run SELECT queries.
  • Built on the CData JDBC Driver for Amazon S3.
  • Integrates with any MCP-compatible AI client.

Use cases of Amazon S3 MCP Server by CData

  • Query object metadata and contents from Amazon S3 buckets using conversational AI.
  • Analyse storage patterns or file inventories without writing SQL.
  • Allow LLMs to reference live S3 data during document generation or analysis.

FAQ from Amazon S3 MCP Server by CData

Is this server read-only or does it support writes?

This server is read-only. For full CRUD functionality, CData offers a separate beta MCP Server with write capabilities.

What dependencies are required to run the server?

Java, Maven, the CData JDBC Driver for Amazon S3 (requires license), and a valid JDBC connection string. Configure these in a .prp file.

Where does the data reside?

Data stays in your Amazon S3 buckets. The server only reads metadata/objects via the JDBC driver; no data is stored or transferred by the server itself.

How does authentication work?

Authentication is configured in the JDBC connection string, typically using OAuth. The driver’s Connection String utility can generate the required string.

What transport does the server use?

The server uses stdio transport, so it must run on the same machine as the client (e.g., Claude Desktop).
