Connect Google Drive to Claude: Turn Every Doc into Answerable Data
By CorpusIQ Team
Most companies do not have a wiki. They have Google Drive. Every proposal, contract, policy, and SOP lives there. Finding anything specific requires remembering the exact title or rough folder location. Search works, sort of, but only if you guess the right keywords.
Connecting Google Drive to Claude through CorpusIQ turns Drive into something you can ask questions of. What does the vendor contract with Acme say about auto-renewal? Where is the latest version of the pricing sheet? What did the Q3 strategy doc conclude? Plain language, real answers.
The problem with the current workflow
Drive's search is keyword-based. It returns a list of files that contain the term. It does not read the files for you, summarize across them, or answer questions from their content. You still have to open each one and scan.
For operators, the cost shows up in two places. First, context-switching: opening five docs to answer one question is exhausting. Second, surfacing old knowledge: a doc written 18 months ago might have the exact answer you need today, but you will never find it because you forgot it exists.
How CorpusIQ solves it
CorpusIQ connects Google Drive to Claude through MCP. Claude can search files by content, list files by folder or type, and read the contents of docs, sheets, and PDFs directly.
Read-only OAuth. Claude cannot create, modify, move, or delete any file.
No data copied. Every query pulls file content from Drive in real time. Nothing is cached or indexed inside CorpusIQ.
Respects Drive permissions. Claude can only read files the connecting user has access to. Sharing permissions in Drive remain the source of truth.
What you can actually do
- "Find every document that mentions our auto-renewal clause and summarize what each one says."
- "Search all PDFs for our insurance certificates, and list the expiration dates."
- "What does the 2024 strategy doc say about our approach to enterprise customers?"
- "Find the latest version of the pricing sheet and summarize the changes from the previous version."
- "List all contracts signed in the last 12 months."
- "Search Drive for vendor NDAs that have not been countersigned."
- "Summarize the Q3 board prep documents into a one-page brief."
- "Find the onboarding checklist for new hires and show me what it contains."
Follow-ups get sharper. Ask about contracts, drill into one, ask what the termination clause specifies, then ask whether the vendor has a right of first refusal.

Where this earns its keep
Professional services firms, consultancies, and any company with a mature Drive benefit immediately. If your institutional knowledge lives in Drive, Claude becomes the layer that makes it interrogable.
Combines with Gmail and Slack for full-context questions. Ask Claude what the vendor agreement says, what the email thread discussed, and what the Slack conversation decided. Three sources, one answer.
What to watch out for
Two caveats.
Drive access is broad by scope. When you connect, Claude can see any file the connecting user has access to, including Shared Drives. If your Drive is messy, Claude will see the mess. Consider connecting with a purpose-scoped account if you want to limit exposure.
Image-only PDFs (scanned docs without OCR) are not readable as text. If your Drive has scanned contracts, Claude cannot extract from them until they are OCR'd.
