Is this server read-only?
Yes. The README explicitly states that this project builds a read-only MCP server. For full read/write/update/delete capabilities, CData offers a separate free beta MCP 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 Microsoft OneDrive (beta)](https://www.cdata.com/download/download.aspx?sku=UOZK-V&type=beta).
Add this server to your MCP-compatible client using the configuration below.

"args": [
"-jar",
"PATH\\TO\\CDataMCP-jar-with-dependencies.jar",
"PATH\\TO\\microsoft-onedrive.prp"

}Tool list not available yet
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.
Microsoft OneDrive MCP Server by CData is a read-only MCP server that lets LLMs query live Microsoft OneDrive data through the CData JDBC Driver for Microsoft OneDrive. The driver exposes OneDrive data as relational SQL models, and the server wraps it into a simple MCP interface so you can ask natural language questions without writing SQL.
Clone the repository, build with mvn clean install, then install and license the CData JDBC Driver for Microsoft OneDrive. Create a .prp file with connection details (Prefix, ServerName, DriverPath, DriverClass, JdbcUrl). Configure Claude Desktop (or another MCP client) by adding the server to claude_desktop_config.json with the path to java and the compiled JAR and .prp file. The server runs over stdio and must be on the same machine as the client.
Yes. The README explicitly states that this project builds a read-only MCP server. For full read/write/update/delete capabilities, CData offers a separate free beta MCP Server.
Authentication uses OAuth via the CData JDBC Driver. When you configure the connection string (e.g., `jdbc:onedrive:InitiateOAuth=GETANDREFRESH;`), the driver will launch a browser for you to log in and grant access.
The server uses `stdio` as its transport, meaning it runs as a local process and communicates over standard input/output. It can only be used with MCP clients that run on the same machine.
Yes. You must download and install the CData JDBC Driver for Microsoft OneDrive and license it (either with a trial key or a purchased license) before the server can connect.
The server exposes three main tools: `{servername}_get_tables` (list all tables), `{servername}_get_columns` (list columns for a given table), and `{servername}_run_query` (execute a SQL SELECT query). Output is returned in CSV format.
