eb_event_details

Read-only

Batch-fetch public event details by ID, with expansions for venue, image, ticket availability, and organizer. Supports up to 20 events per request.

Instructions

Batch-fetch public event details by id. Uses your bearer token by default, falling back to the browser bridge when no token is configured. For ticket-class detail prefer eb_ticket_classes.

Input Schema

TableJSON 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.
expandNoComma-separated expansions (default primary_venue,image,ticket_availability,event_sales_status,primary_organizer)
event_idsYesNumeric event ids

A4.8/5.0
Behavior5/5

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

Beyond the readOnlyHint and openWorldHint annotations, the description discloses authentication fallback behavior and detailed response-shape semantics: compact drops image/avatar URLs, full returns Eventbrite payload untouched, and no field projection is performed. This is valuable behavioral context an agent would not otherwise know.

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?

The description is three concise sentences, front-loaded with the core purpose. It has zero filler and each sentence earns its place: what it does, how auth works, and which sibling to prefer.

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

Completeness5/5

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

For a batch-fetch read tool with rich input schema and readOnly/openWorld annotations, the description covers purpose, auth, response-shape choices, and sibling differentiation. Without an output schema, the description gives enough context to call the tool correctly.

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

Parameters5/5

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

Schema coverage is 100%, so the baseline is 3, but the description adds significant extra meaning for the view parameter, explaining exactly what compact/full do and why there is no field projection. It also ties event_ids to the batch-fetch purpose.

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 opens with a specific verb and resource: 'Batch-fetch public event details by id.' This clearly distinguishes the tool from single-resource siblings like eb_event and from ticket-class-specific tools.

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?

It explicitly says when not to use it: 'For ticket-class detail prefer eb_ticket_classes.' The description also gives useful context about authentication fallback, but does not explicitly contrast with eb_event or other event-fetching siblings.

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