Export your own Microsoft 365 data — Teams chats, Outlook mail, calendar, contacts, OneDrive files — through Microsoft Graph, then search it offline: full-text and semantic ranking fused into one list, plus a built-in MCP server so Claude can search the archive. Delegated access, no admin consent. Nothing leaves your machine.
n-schilling/office_365_exporter is an MCP server distributed on github, maintained by n-schilling, tracked here since August 2026. It has shipped 4 releases and exposes 10 tools. Tools include archive_unavailable, browse_messages, corpus_stats, get_document, get_thread, list_filetypes, and 4 more. Its composite risk grade is B — an inferred review prompt computed from observed signals, not a verdict.
Reading the source raised one review prompt — exfiltration combo — each a pattern worth a human look rather than a finding of fault.
Since the previous scan on 2026-08-30: 2 tools added.
