TWW MCP Drive & Calendar

TWW MCP Drive & Calendar

A private internal tool of The White Willow. Not a public product. It cannot be signed up for, purchased, or used by anyone outside our organisation.

What it is

TWW MCP Drive & Calendar is an internal Model Context Protocol (MCP) service that lets The White Willow's own AI assistants search and read files, manage calendar entries, and create working documents for two specific, named Google accounts that we control.

It exists so that our own staff can ask questions like "find the supplier agreement we signed in March" or "what meetings do I have with the logistics vendor next week" without hunting through Drive and Calendar by hand.

Who can use it

Access is restricted to two pre-authorised Google accounts belonging to the operator. The list of permitted accounts is fixed in the service's server-side configuration. No sign-up exists. Any request naming an account outside that list is rejected before any Google data is touched.

What it can do

Reading (whole Drive, whole calendar):

  • Search Google Drive by file name and full text, and read file contents (Google Docs, Sheets, Slides, PDFs with a text layer, and plain-text formats)
  • List the calendars on the account
  • Search calendar events and read event details

Creating and editing (deliberately narrow):

  • Create Google Docs, Sheets and Slides, and plain text/Markdown/CSV/JSON files
  • Create folders
  • Edit the contents of files this service itself created
  • Create, reschedule and edit calendar events, manage attendees and reminders, set up recurring events, and cancel events

New files are placed in a dedicated TWW AI Workspace folder by default, so assistant-generated material stays separate from existing work.

What it cannot do

The reading and writing permissions are deliberately asymmetric.

  • It can read the whole Drive, but it will only edit files it created itself. The service stamps every file it creates with a private marker and refuses to modify anything that is not stamped. It holds per-file write access (drive.file) rather than general Drive write access, and the refusal happens in the service before any write is attempted.
  • It cannot share files, change permissions, or alter who can see anything.
  • It cannot create, delete, or reconfigure whole calendars, and cannot change calendar sharing or account settings.
  • There is no tool that deletes arbitrary Drive files.
