What transport does the server use?
The server uses `stdio` transport, so it can only be used with clients that run on the same machine as the server.

Basic information
This project builds a read-only MCP server. For full read, write, update, delete, and action capabilities and a simplified setup, check out our free CData MCP Server for Avro (beta): https://www.cdata.com/download/download.aspx?sku=JNZK-V&type=beta
Add this server to your MCP-compatible client using the configuration below.

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.
Avro MCP Server by CData is a read-only Model Context Protocol (MCP) server that enables large language models (LLMs) such as Claude Desktop to query live Avro data using natural language. It wraps the CData JDBC Driver for Avro, which exposes Avro files as relational SQL models, so no SQL knowledge is required from the user.
Clone the repository, build with Maven (mvn clean install), then install and license the CData JDBC Driver for Avro. Create a .prp property file with your connection settings (including DriverPath, DriverClass, and JdbcUrl). Configure Claude Desktop by adding the server to claude_desktop_config.json or run the server standalone with java -jar PATH/TO/CDataMCP-jar-with-dependencies.jar PATH/TO/avro.prp. The server exposes tools for listing tables, columns, and executing SQL SELECT queries.

Yes, this project builds a read‑only MCP server. For full read, write, update, delete, and action capabilities, CData offers a separate beta MCP Server for Avro.
Java, Maven, and the CData JDBC Driver for Avro (which must be downloaded, installed, and licensed separately).
Create a `.prp` file with properties such as `Prefix`, `ServerName`, `DriverPath`, `DriverClass`, and `JdbcUrl`. Use the JDBC connection string utility to test and obtain the correct `JdbcUrl`.
Contact the CData Support Team for connection issues. For MCP server feedback, join the CData Community.
