This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.
We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.
A read-only MCP server that lets LLMs like Claude Desktop query live Azure Data Lake Storage data using natural language. It wraps the CData JDBC Driver for Azure Data Lake Storage, which exposes the storage as relational SQL models.
Clone the repo, build with mvn clean install, download and license the CData JDBC Driver for Azure Data Lake Storage, configure a connection string, create a .prp file with connection details, and add the server to Claude Desktop’s claude_desktop_config.json. Run with java -jar CDataMCP-jar-with-dependencies.jar <path-to>.prp. The server uses stdio transport and must run on the same machine as the client.
get_tables, get_columns, run_query (SELECT only)Yes, the server explicitly states it is read-only. For full create, read, update, delete and action capabilities, use the free CData MCP Server for Azure Data Lake Storage (beta) linked in the README.
Java and the CData JDBC Driver for Azure Data Lake Storage must be installed and licensed. The driver JAR file path is specified in the `.prp` configuration.
It uses `stdio` transport, so the server must be run on the same machine as the MCP client (e.g., Claude Desktop).
No, this server only supports SELECT queries via the `run_query` tool. No INSERT, UPDATE, DELETE, or custom actions are available.
The README instructs you to use the CData JDBC Driver’s connection string utility. If the data source uses OAuth, you will authenticate in your browser during the connection test.
