Eg. PDFs have only their text contents extracted and returned to the MCP client.nn### How to usen* This Google Drive MCP server allows any compatible MCP client to manage a person or shared Google Drive. Simple select a drive or for better control, specify a folder within the drive to scope the operations to.n* Connect your MCP client by following the n8n guidelines here - https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-langchain.mcptrigger/#integrating-with-claude-desktopn* Try the following queries in your MCP client:n * "Please help me search for last month's expense reports."n * "What does the company policy document say about cancellations and refunds?"nn### Requirementsn* Google Drive for documents.n* OpenAI for image and audio understanding.n* MCP Client or Agent for usage such as Claude Desktop - https://claude.ai/downloadnn### Customising this workflown* Add additional capabilities such as renaming, moving and/or deleting files.n* Remember to set the MCP server to require credentials before going to production and sharing this MCP server with others!"
