mcp-google-drive

This MCP server integrates Google Drive with the MCP workflow, enabling you to upload Microsoft Word files directly to Google Drive via the upload_microsoft_world_file tool. Once configured, you can connect with an MCP client (for example Claude Desktop) and invoke the upload tool to store documents in a specified Google Drive folder or in the root if no folder is provided. The tool returns a URL to the uploaded file in Google Docs view format, making it easy to share or reference the document from within your MCP-enabled conversations.

Prerequisites:

• Claude Desktop or another MCP client
• Java 24+ and Maven (or use the Native Binary as described)
• Google Cloud project with Drive API enabled and credentials file

Installation steps:

1. Clone the repository and navigate to the project:

git clone <this-repo>
cd mcp-google-drive-server

2. Build the native binary (STDIO mode) or the jar (Java build):

# Native binary (No Java)
./mvnw clean package -Pnative,mcp-stdio

# Java build (Traditional)
./mvnw clean package

3. Obtain Google application credentials as described in the README and place the credentials file locally, e.g. application_default_credentials.json.
4. Run or configure the server with the appropriate command and environment, as shown below (configuring via MCP client is described in the Running section):

{
  "mcpServers": {
    "mcp-google-drive-server": {
      "command": "/FULL/PATH/TO/target/mcp-google-drive-server",
      "args": [],
      "env": {
        "GOOGLE_APPLICATION_CREDENTIALS": "/FULL/PATH/TO/application_default_credentials.json"
      }
    }
  }
}

Tips and common issues:

• Ensure the GOOGLE_APPLICATION_CREDENTIALS file points to a valid service account credential with Drive access.
• Use absolute paths for the binary/jar and credentials in your MCP config.
• If the MCP tool cannot be found in Claude Desktop, verify the binary/jar path and environment variables, then restart Claude Desktop.
• When testing with MCP Inspector, you may need to supply a valid access token obtained from the /oauth2/token endpoint using client credentials.
• For the native binary, the startup time is very fast; for the Java build, the startup will depend on the JVM and jar size.
• The server exposes the upload_microsoft_world_file tool which takes folderName (optional), fileName, and fileContent; the tool returns a Google Drive URL.
