Connect SharePoint to Claude: Enterprise Documents Meet AI Intelligence

Microsoft SharePoint is the document management backbone for most Fortune 500 companies — hosting millions of documents, policies, reports, and presentations. But finding the right document often means navigating complex folder structures, remembering exact file names, or relying on SharePoint's limited search capabilities. Connecting SharePoint to Claude via CorpusIQ's MCP platform transforms your enterprise document library into an AI-queryable knowledge repository.

Ask Claude "Find the Q3 financial close presentation", "What does our data retention policy say about customer PII?", or "Show me all documents related to the [Project Name] initiative" and Claude will search your SharePoint libraries, read relevant documents, and synthesize answers — all in seconds.

Why Connect SharePoint to Claude?

SharePoint stores your organization's most important documents, but accessing the knowledge inside those documents is hard. Claude reads the content, not just the file names, and delivers answers rather than search results.

Key benefits:

  • Content-level search, not just metadata. Claude reads Word documents, PowerPoint presentations, Excel spreadsheets, and PDFs stored in SharePoint, not just file names and titles.
  • Policy and compliance instant answers. "What's our travel reimbursement policy for international trips?" — Claude reads the actual policy document and answers specifically.
  • Cross-document synthesis. "Compare our Q2 and Q3 strategy presentations" — Claude reads both files and delivers a synthesized comparison.
  • Enterprise search democratized. Any employee can find institutional knowledge without knowing which folder or site it lives in.
  • Meeting preparation. Before a client meeting, ask Claude to find and summarize all relevant documents stored in SharePoint.
  • Read-only Microsoft Graph integration. Claude can search and read but can never modify, delete, or upload documents.

How It Works

  1. Connect Microsoft 365 via OAuth 2.0. CorpusIQ requests read-only access to SharePoint sites and files via Microsoft Graph.
  2. Ask Claude any question about your enterprise documents.
  3. CorpusIQ searches SharePoint document libraries and reads relevant files using Microsoft Graph API.
  4. Claude synthesizes the content into a coherent answer with document citations.

Claude accesses documents that the authenticated user has permission to view. SharePoint permissions are fully respected.

Setup Steps

  1. Navigate to Connectors in CorpusIQ.
  2. Select SharePoint (under Microsoft 365 integrations).
  3. Click "Connect SharePoint" — authorize via Microsoft OAuth.
  4. Review permissions: Sites.Read.All, Files.Read.All (read-only access to SharePoint sites and files).
  5. Start asking Claude about your enterprise documents.

For organizations with Conditional Access policies, CorpusIQ supports Microsoft Entra ID (Azure AD) administrative consent workflows.

Enterprise Security

SharePoint contains some of your organization's most sensitive documents. CorpusIQ's integration is built with enterprise security requirements:

  • Read-only OAuth 2.0. Claude can search and read documents but can never modify, delete, create, or upload files.
  • SharePoint permissions respected. Claude only sees documents the authenticated user has permission to access.
  • Conditional Access support. Works with Microsoft Entra ID Conditional Access policies including MFA requirements, device compliance, and location-based restrictions.
  • No document storage. File contents are never persisted on CorpusIQ servers. Every query streams content directly from SharePoint.
  • Audit logging. All queries are logged in CorpusIQ for compliance visibility.

Enterprise Deployment Considerations

For large organizations deploying SharePoint integration across teams:

  • Admin consent workflow. IT administrators can pre-authorize the integration for the entire tenant using Microsoft Entra admin consent.
  • Site collection scoping. Administrators can configure which SharePoint site collections are accessible.
  • Sensitivity label awareness. Documents with Microsoft Information Protection sensitivity labels retain their classification metadata.
  • Compliance with data residency. All data processing respects your Microsoft 365 data residency configuration.

Comparison: MCP vs. SharePoint API Direct

FAQ

Q: What file types can Claude read from SharePoint? A: Claude can read Word documents (docx), PowerPoint (pptx), Excel (xlsx), PDFs, and text files stored in SharePoint document libraries.

Q: Can Claude access SharePoint Online and on-premises SharePoint? A: The integration supports SharePoint Online through Microsoft Graph. On-premises SharePoint is not currently supported.

Q: How does this work with large document libraries (millions of files)? A: CorpusIQ uses Microsoft Graph search APIs to efficiently find relevant documents. Claude processes only the most relevant results.

Q: Can I restrict which SharePoint sites Claude can access? A: Yes. Configure site collection scope during OAuth authorization or through Microsoft Entra admin consent.

Q: Does this work with Teams-shared files? A: Yes. Files shared in Microsoft Teams channels are stored in SharePoint and are accessible through the same integration.

Q: What about documents protected by Azure Information Protection? A: Documents with sensitivity labels are accessible, and label metadata is preserved. Claude cannot bypass encryption or rights management protections.
