SharePoint MCP Integration

Weldable's SharePoint MCP integration gives your AI agents direct access to your SharePoint sites, document libraries, and lists through natural language. Your agent can search for files, read document content, manage list items, and upload files without anyone navigating SharePoint's folder structures or site hierarchies.

SharePoint is where enterprise knowledge goes to live (and often, to get lost). The SharePoint MCP ecosystem has grown quickly, with servers that connect through the Microsoft Graph API to provide document search, content extraction from PDFs and Office files, and full CRUD operations on lists. Weldable handles the Graph API authentication and session management so your agent stays connected and can combine SharePoint data with actions across your other integrations.

Use cases

Document search and retrieval

Your agent searches across SharePoint sites and libraries by file name, content keywords, or metadata. Ask "find the latest brand guidelines in the Marketing site" and the agent returns the document with a direct link. It can also extract text content from PDFs, Word documents, and PowerPoint files, so your agent can answer questions about what's inside a document without anyone opening it.

Policy and procedure lookups

When an employee asks "what's our expense reimbursement policy?", your agent searches the relevant SharePoint library, finds the current policy document, extracts the key sections, and returns a summary. This turns SharePoint from a static file repository into an active knowledge base that answers questions on demand.

List management for project tracking

SharePoint lists power everything from project trackers to asset inventories. Your agent can add new items, update existing entries, filter by column values, and pull summary views. Ask "show me all open items in the vendor onboarding tracker assigned to the legal team" and the agent queries the list and returns the matching rows.

Automated document distribution

When a new report or deliverable is ready, your agent uploads it to the correct SharePoint library, sets the metadata fields (document type, owner, review date), and notifies the relevant team via Slack or email. This removes the manual step of uploading, tagging, and announcing new content that many teams repeat weekly.

Content audit and cleanup

Your agent scans document libraries for files that haven't been modified in over a year, documents with missing metadata, or duplicate files across sites. It generates an audit report listing the stale content with last-modified dates and owners. The report goes to the SharePoint admin or site owner so they can decide what to archive or delete.

How it works

Connect your Microsoft account through Weldable's OAuth flow. Weldable authenticates through the Microsoft Graph API and requests the SharePoint-specific scopes (Sites.ReadWrite.All, Files.ReadWrite.All). Tokens refresh automatically in the background.

Once connected, describe what you need in plain English. Say "list all documents in the Engineering site's design specs library" or "add a new row to the hiring tracker with candidate name and interview date" and Weldable translates your intent into the correct Graph API calls. The agent resolves site names, library names, and list columns behind the scenes.

Tips

Always specify the site name. Large organizations can have hundreds of SharePoint sites. Including the site name in your request (e.g., "the Finance team site" or "the HR policies site") helps the agent search in the right place. Without this, searches return results from across the entire tenant, which is slow and often noisy.

SharePoint list columns have internal names. The display name you see in the SharePoint UI (like "Due Date") may differ from the internal column name (like "DueDate0"). Your agent handles this translation for common columns, but custom columns with special characters in their names may need the internal name specified explicitly.

Document metadata improves search quality. SharePoint supports custom metadata columns on document libraries (content type, department, status). Files with populated metadata are easier for your agent to find and filter. If your search results are inconsistent, check whether the target documents have their metadata filled in.

Permissions are inherited from sites and libraries. Your agent can only access sites and libraries that the authenticated user has permission to view. If a document search returns no results for content you know exists, verify that the connected account has the right site-level permissions.

Large file downloads have Graph API limits. The Microsoft Graph API handles file downloads up to 4 MB inline. Larger files require a download URL redirect. Your agent handles this automatically, but be aware that very large files (hundreds of MB) may take longer to process.
