RSVP / join a TavernFinder event on behalf of the authenticated user. Requires a personal access token with the write:rsvp scope. Use search_events first to find the venueId + eventId pair.
| Name | Required | Description | Default |
|---|---|---|---|
| eventId | Yes | UUID of the specific event to join | |
| venueId | Yes | UUID of the venue hosting the event | |
| accessCode | No | Access code, only needed if the event is access-code-protected |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description must carry the transparency burden. It discloses the authentication scope requirement and that it acts on behalf of the authenticated user, but it does not explain what happens if the user is already RSVP'd, idempotency, or the response format. These are meaningful behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the core verb and resource, and every sentence adds useful context. No filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simple action and the 100% schema coverage, the description covers the key prerequisites (auth scope, search_events) and the core behavior. It lacks explicit return-value documentation, but for an RSVP action this is not critical. It's generally complete for the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All parameter descriptions are in the schema (100% coverage), so the description adds minimal additional meaning. It does reinforce the need for both venueId and eventId as a pair, but doesn't add extra semantic detail beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('RSVP / join'), the target resource ('TavernFinder event'), and the scope ('on behalf of the authenticated user'). It also references the prerequisite search_events, which helps distinguish this from create_event or register_user.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly instructs 'Use search_events first to find the venueId + eventId pair', providing a clear when-to-use directive and a sequenced alternative. It also specifies the required scope, giving additional context for when this tool should be invoked.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct resource and action: user registration, event creation, RSVP, and separate searches for events, games, and venues. There is no overlap in purpose, so an agent can easily select the right tool.
All tool names follow the verb_noun pattern (create_event, register_user, rsvp_event, search_events, search_games, search_venues). Even 'rsvp_event' uses a verb-like acronym consistently, and the snake_case style is uniform.
Six tools is well within the ideal 3-15 range for a focused domain. Each tool has a clear role, and there are no redundant or excessive entries.
The toolset covers the main workflows: searching for venues/games/events, creating events, RSVPing, and registering users. Minor gaps exist such as no cancel_rsvp or update_event, but these are not core dead ends and agents can work around them.
