eb_org_attendees

Read-only

List attendees across an organization's Eventbrite events. Filter by attending status and paginate results for organizer reporting.

Instructions

List attendees across an organization's events (organizer side).

Input Schema

NameRequiredDescriptionDefault
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full" returns Eventbrite's payload untouched. No field projection on this tool: this server has no verified record of which Eventbrite fields matter here, and inventing one would risk dropping a field a caller needs.
org_idYesOrganization id (from eb_my_organizations)
statusNoAttendee status filter
continuationNoPagination continuation token from a previous response

B3.3/5.0
Behavior2/5

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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds no behavioral context of its own: nothing about pagination despite the continuation parameter, nothing about how results are aggregated across events, and nothing about authorization scope beyond the vague 'organizer side'.

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?

A single front-loaded sentence with zero filler; the resource and its scope come first. Given the schema carries the parameter detail, this is appropriately sized.

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

Completeness3/5

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

With no output schema, the description should say more about what a caller gets back — the aggregate-per-event shape and the continuation-token pagination are left unstated. Annotations cover safety, and the schema covers inputs, so the remaining gap is return/pagination behavior.

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?

Schema description coverage is 100%, so all four parameters including the enum filters and continuation token are documented in the schema itself. The description contributes no additional parameter meaning, so the baseline 3 applies.

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

Purpose4/5

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

Specific verb (List) plus resource (attendees) plus a scoping qualifier (across an organization's events, organizer side) that distinguishes it from the event-level sibling eb_event_attendees. It does not name that sibling explicitly, but the 'organization's events' scope makes the boundary inferable.

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

Usage Guidelines3/5

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

The parenthetical '(organizer side)' hints at the caller context, implying use when operating as an organizer rather than a single event's perspective. However, no alternative tool is named, no when-not condition is given, and no prerequisite (e.g., needing an org_id from eb_my_organizations) is stated.

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