Add an inline comment anchored to a specific text fragment in a Google Doc (the comment is pinned to that exact phrase, like selecting text and commenting on it by hand). USE THIS WHEN the user wants to leave feedback, notes, questions, edits, or review comments on specific passages of a Google Doc — e.g. "review this doc and comment on the weak spots", "leave a comment on that sentence", "add editorial feedback inline". This is the ONLY way to place anchored comments: the Google Docs and Drive APIs cannot anchor a comment to a text range, so this drives a real logged-in Docs session in a browser. Do NOT use for list/reply/resolve/delete — those work over the Drive API. Requires a one-time npx gdocs-comments-mcp login by the human operator (you cannot log in for them). Omit find_text to add a general, unanchored comment on the document instead. Returns only { ok, anchored, occurrence_used, verified } — never document content.

Check whether the Google session behind this server is usable: launches/attaches the browser and probes docs.google.com. Returns { connected, mode }. Call this to diagnose failures; if connected=false, ask the operator to run npx gdocs-comments-mcp login.
