list-mail-rules

Read-only

Retrieve all message rules defined for a user's inbox, including conditions, actions, and exceptions, to manage email sorting and automation.

Instructions

Get all the messageRule objects defined for the user's inbox.

đź’ˇ TIP: Lists all message rules for a mail folder. Use the Inbox folder ID (get it from list-mail-folders) for inbox rules. Each rule has displayName, sequence, isEnabled, conditions (fromAddresses, subjectContains, etc.), actions (moveToFolder, forwardTo, delete, etc.), and exceptions.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
topNoPage 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 rows, use @odata.nextLink from the response instead of a very large $top.
skipNoItems to skip for pagination. Not supported with $search.
searchNoKQL search query — wrap value in double quotes. Cannot combine with $filter.
filterNoOData filter expression. Add $count=true for advanced filters (flag/flagStatus, contains()). Cannot combine with $search.
countNoSet true to enable advanced query mode (ConsistencyLevel: eventual). Required for complex $filter on flag/flagStatus or contains().
orderbyNoSort expression, e.g. receivedDateTime desc
selectNoComma-separated fields to return, e.g. id,subject,from,receivedDateTime
expandNoExpand related entities
mailFolderIdYesPath parameter: mailFolderId
fetchAllPagesNoFollow @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 small $top first, then paginate or narrow with $filter/$search.
includeHeadersNoInclude response headers (including ETag) in the response metadata
excludeResponseNoExclude the full response body and only return success or failure indication
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and destructiveHint=false, covering the safety profile. The description adds a list of returned fields but does not disclose additional behavioral traits like pagination limits or data freshness.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences: one for purpose and one tip. No redundant information, front-loaded with the main action. Excellent conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Explains return value fields (displayName, sequence, etc.) in the absence of an output schema. However, lacks guidance on pagination or handling large rule sets, which is relevant given the schema parameters for pagination.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has 100% coverage with detailed parameter descriptions. The description does not add meaningful parameter semantics beyond referring to the Inbox folder ID. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states it retrieves all messageRule objects for a user's inbox. Differentiates from sibling tools like create-mail-rule and delete-mail-rule by specifying it is a read-only list operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides a tip to get the Inbox folder ID from list-mail-folders, implying the proper context for use. Does not explicitly mention when not to use it, but the purpose is clear enough to distinguish from mutation tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
