This read-only MCP server allows LLMs like Claude Desktop to query live Microsoft Excel data. It wraps the CData JDBC Driver for Microsoft Excel, which exposes Excel data as relational SQL models, so users can retrieve information using natural language without writing SQL.
Clone the repository, build with mvn clean install, install and license the CData JDBC Driver for Microsoft Excel, configure a .prp file with your JDBC connection string, then add the server to your client’s MCP configuration (e.g., claude_desktop_config.json). The server runs via stdio and is invoked by the client.
Yes, the project builds a read-only MCP server. The README explicitly states it is read-only and points to a separate beta version for full read/write/update/delete capabilities.
You need Java, Apache Maven to build the project, and the CData JDBC Driver for Microsoft Excel (must be downloaded and licensed separately).
Data stays in your local Excel files or network location as configured in the JDBC connection string. The server processes queries locally and does not send data externally beyond what the client (e.g., Claude Desktop) uses.
The server uses `stdio` transport, so it can only be used with clients running on the same machine as the server.
Authentication is handled through the CData JDBC Driver’s connection string. You configure OAuth or other credentials using the driver’s Connection String utility before running the server.
