WHAT IT DOES

What search-onedrive-files does on Ms 365

AI agents call search-onedrive-files 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
`q`	string	Yes	Value for the 'q' path segment.
`top`	number	—	Page size (Graph $top). Start small (e.g. 5–15) so responses fit the model context; raise only if needed. Use $select to return fewer fields per item. For more
`skip`	number	—	Items to skip for pagination. Not supported with $search.
`count`	boolean	—	Set true to enable advanced query mode (ConsistencyLevel: eventual). Required for complex $filter on flag/flagStatus or contains().
`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
`filter`	string	—	OData filter expression. Add $count=true for advanced filters (flag/flagStatus, contains()). Cannot combine with $search.
`search`	string	—	KQL search query — wrap value in double quotes. Cannot combine with $filter.
`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.
`orderby`	string	—	Sort expression, e.g. receivedDateTime desc
`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

Parameters from the server's own tool schema.

RISK

Why search-onedrive-files is rated Low

Even though search-onedrive-files only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

The rule that runs search-onedrive-files 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 search-onedrive-files, this is the rule to start with:

search-onedrive-files Allowed

search-onedrive-files is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search-onedrive-files": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Ms 365, apply this rule, and every search-onedrive-files call is checked against it from then on.
