gmail-mcp-server-by-cdata is a read-only Model Context Protocol (MCP) server built by CData that allows LLMs like Claude Desktop to query live Gmail data. It wraps the CData JDBC Driver for Gmail, which exposes Gmail data as relational SQL models, so users can retrieve live information using natural language—no SQL required.
Clone the repository, build the JAR with Maven, download and license the CData JDBC Driver for Gmail, create a .prp file with your JDBC connection string, then configure Claude Desktop’s claude_desktop_config.json to point to the server. The server runs via java -jar using stdio transport. Once configured, ask your LLM questions about your Gmail data—the built-in tools ({servername}_get_tables, {servername}_get_columns, {servername}_run_query) are invoked automatically.

You need Java installed, Maven to build the JAR, and the CData JDBC Driver for Gmail (trial or licensed). The server runs on the same machine as the LLM client (uses `stdio` transport).
The server queries live Gmail data through the CData JDBC Driver. No data is stored locally; all queries go directly to Gmail via the driver.
The server uses `stdio` transport and can only be used with clients that run on the same machine as the server.
Authentication (OAuth) is configured via the CData JDBC Driver’s connection string utility. When OAuth is required, you will be prompted to authenticate in your browser during setup.
