What get-calendar-view does on Ms 365
AI agents call get-calendar-view 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 |
|---|---|---|---|
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 |
orderby | string | — | Sort expression, e.g. receivedDateTime desc |
timezone | string | — | IANA timezone name (e.g., "America/New_York", "Europe/London", "Asia/Tokyo") for calendar event times. If not specified, times are returned in UTC. |
endDateTime | string | Yes | The end date and time of the time range, represented in ISO 8601 format. For example, 2019-11-08T20:00:00-08:00 |
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 |
startDateTime | string | Yes | The start date and time of the time range, represented in ISO 8601 format. For example, 2019-11-08T19:00:00-08:00 |

Why get-calendar-view is rated Low
Even though get-calendar-view 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.
Risk signalsHigh parameter count (15 properties)
Attacks that exploit this kind of access
The rule that runs get-calendar-view 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-calendar-view, this is the rule to start with:
get-calendar-view is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ms 365, apply this rule, and every get-calendar-view call is checked against it from then on.
Questions about get-calendar-view
Get the occurrences, exceptions, and single instances of events in a calendar view defined by a time range, from the user's default calendar, or from some other calendar of the user. 💡 TIP: Returns expanded recurring event instances (not just seriesMaster) within a date range for the default calendar. Requires startDateTime and endDateTime query parameters in ISO 8601 format (e.g., 2024-01-01T00:00:00Z). Use get-specific-calendar-view if you need a non-default calendar. To find Teams meetings, use $filter=isOnlineMeeting eq true. To search by subject, use $filter=contains(subject,'keyword'). Teams meetings include a joinWebUrl property needed for transcript access via list-online-meetings. It is categorised as a Read tool in the Ms 365 MCP Server, which means it retrieves data without modifying state.
get-calendar-view accepts 12 parameters: top, skip, count, expand, filter, search, select, orderby, timezone, endDateTime, fetchAllPages, startDateTime. Required: endDateTime, startDateTime. The full parameter table on this page comes from the server's own tool schema.
Register the Ms 365 MCP server in PolicyLayer and add a rule for get-calendar-view: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ms 365. Nothing to install.
get-calendar-view is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get-calendar-view rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get-calendar-view. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get-calendar-view is provided by the Ms 365 MCP server (@jo3zik/ms-365-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
