WHAT IT DOES

What share-drive-item does on Ms 365

AI agents use share-drive-item to create or update resources in Ms 365, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ms 365 environment.

Parameter	Type	Required	Description
`body`	object	Yes

`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.

RECOMMENDED RULE

The rule that runs share-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 share-drive-item, this is the rule to start with:

share-drive-item Rate-limited

share-drive-item stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
