WHAT IT DOES

What get-drive-item does on Ms 365

AI agents call get-drive-item to retrieve information from Ms 365 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`expand`	array	—	Navigation properties to inline, e.g. attachments on a message or event. Only navigation properties can be expanded: expanding a non-navigation property such as
`select`	string	—	Comma-separated fields to return, e.g. id,subject,from,receivedDateTime
`driveId`	string	Yes	Value for the 'driveId' path segment. Pass it under the name 'driveId', not as 'id'. Use the 'id' field of the drive object as returned by Microsoft Graph.
`driveItemId`	string	Yes	Value for the 'driveItemId' path segment. Pass it under the name 'driveItemId', not as 'id'. Use the 'id' field of the drive item object as returned by Microsof
`fetchAllPages`	boolean	—	Follow @odata.nextLink and merge up to 100 pages into one response. Can return enormous payloads—only when the user explicitly needs a full export. Prefer a sma
`includeHeaders`	boolean	—	Include response headers (including ETag) in the response metadata
`excludeResponse`	boolean	—	Exclude the full response body and only return success or failure indication

Parameters from the server's own tool schema.

RISK

RECOMMENDED RULE

The rule that runs get-drive-item safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ms 365, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get-drive-item, this is the rule to start with:

get-drive-item Allowed

get-drive-item is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
