Microsoft Calendar
MICROSOFT 365 · CALENDAR
Read free/busy and schedule meetings through Microsoft Graph.
Acts as the person, not as itself
Each user connects their own account. Every call carries both identities — the agent and the person it is acting for — so the agent can never reach past what that individual can already do.
Credentials never touch the agent
Tokens live in the vault and attach server-side at call time. The agent holds a session, not a secret, and revoking access does not mean rotating a key.
Every call on the record
Who asked, which agent acted, which action ran, and the verdict that let it through — one audit trail across every integration, not one per vendor.
What an agent can do
Each action is granted on its own. An agent allowed to read is not thereby allowed to write, and the scope beside each row is what the acting user must have connected for it to run at all.
