Server instructions
Microsoft 365 MCP exposes Microsoft Graph through MCP tools. Use each tool name, description, and parameter schema as the source of truth. Microsoft Graph OData: do not combine $filter with $search on the same request. For lists, prefer modest $top (or top) and $select; avoid very large pages unless the user needs them. Mail and message $search uses KQL; the $search query parameter value must be double-quoted per Graph (see search-query-parameter in Microsoft Graph docs). When you need an organizational user or recipient address, resolve it with list-users (or another directory tool); do not invent SMTP addresses. Directory $search on collections such as /users or /groups requires ConsistencyLevel: eventual when the tool exposes that header. Teams chat and channel messages: prefer HTML contentType in the body; plain text is often mangled by Graph. Files / binary content: use download-bytes for any binary read (drive file content, mail attachments, profile photos, Teams hosted content, meeting recordings); pass it a Graph path or an absolute @microsoft.graph.downloadUrl from a metadata response. For uploads, upload-file-content takes a base64 string body up to 4MB; use create-upload-session above that. Work/school-only tools require starting the server with --org-mode.
