list-contact-folders

list-contact-folders
Read-only

Get the list of Outlook contact folders for the signed-in user. Discover folder IDs to manage or create contacts in specific folders.

Instructions

Get the contact folder collection in the default Contacts folder of the signed-in user.

đź’ˇ TIP: Lists the user's Outlook contact folders (the named buckets that organize contacts). Always includes the built-in 'Contacts' folder; user-created folders also appear. Returns id, displayName, and parentFolderId. To identify the default folder, match displayName === 'Contacts'. Use this before list-contact-folder-contacts or create-contact-in-folder to discover folder ids. Supports OData query parameters.

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.
countNoSet true to enable advanced query mode (ConsistencyLevel: eventual). Required for complex $filter on flag/flagStatus or contains().
expandNoNavigation properties to inline, e.g. attachments on a message or event. Only navigation properties can be expanded: expanding a non-navigation property such as a message body fails with "Parsing OData Select and Expand failed", and an unsupported value may be ignored rather than reported. Request ordinary fields with $select instead.
filterNoOData filter expression. Add $count=true for advanced filters (flag/flagStatus, contains()). Cannot combine with $search.
searchNoKQL search query — wrap value in double quotes. Cannot combine with $filter.
selectNoComma-separated fields to return, e.g. id,subject,from,receivedDateTime
orderbyNoSort expression, e.g. receivedDateTime desc
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
Behavior4/5

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

Annotations indicate read-only and non-destructive. The description adds value by explaining that the response includes id, displayName, and parentFolderId, and that OData query parameters are supported. It also notes that the built-in 'Contacts' folder is always returned, which is helpful behavioral context.

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

Conciseness4/5

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

The description is concise, with a clear main sentence followed by a helpful tip section. It is front-loaded with the primary purpose and avoids verbosity, though it could potentially be slightly shorter.

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?

Given no output schema, the description adequately specifies the returned fields and mentions OData support. It provides sufficient context for an agent to understand the tool's output and usage, though additional details about pagination behavior could be beneficial.

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 coverage is 100%, so the baseline is 3. The description mentions OData query parameters in a tip but does not provide detailed semantic meaning beyond what the schema already offers. It adds minimal extra value.

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?

The description clearly states the tool retrieves the contact folder collection from the default Contacts folder of the signed-in user. It specifies returned fields (id, displayName, parentFolderId) and distinguishes from sibling tools like list-contact-folder-contacts and create-contact-in-folder by noting that this tool is used to discover folder IDs before using those.

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?

The description explicitly advises using this tool before list-contact-folder-contacts or create-contact-in-folder to obtain folder IDs. It also notes the built-in 'Contacts' folder is always included. However, it does not explicitly state when not to use this tool, but the context is clear enough.

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