Google Drive: Manage file comments — MCP tool

Google Drive MCP tool: Reads, writes, resolves and deletes the comment threads on a Drive file.

Technical name: manage_comments

What task it solves

I want to work with the comments on a file.

One tool for the Drive comment lifecycle: list/get read threads, create starts one, reply answers, resolve/reopen close or reopen, delete removes.

When to use it

Use it to review feedback on a Doc/Sheet/PDF, answer review comments, close finished threads, or leave a note on a file for collaborators.

What to provide

  • file_id — required; action — required: list, get, create, reply, resolve, reopen or delete.
  • create: content (plus optional quoted_text / anchor); reply: comment_id + content; resolve/reopen: comment_id (optional closing content); get/delete: comment_id.
  • list: optional page_size, page_token, include_deleted.

What it returns

Comment objects: id, content, author, createdTime/modifiedTime, resolved, quotedFileContent and the replies (with their resolve/reopen actions).

What changes in Google Drive

create/reply/resolve/reopen add visible activity that notifies collaborators; delete permanently removes a comment and all its replies — the reason the whole tool is flagged destructive. list/get change nothing.

Example request

List the unresolved comments on the design doc in Google Drive and reply to the first one that it is fixed.

Errors and limitations

Comments created through the API cannot be positionally anchored inside a Doc's text — quoted_text displays the passage but the comment appears at file level. Docs "suggestions" are out of reach. Deleting is author-only.
