Generate booking URL for selected flight options. Creates a personalized booking link that directs users to complete their flight reservation with pre-filled search criteria and selected flights.
| Name | Required | Description | Default |
|---|---|---|---|
| flight_ids | Yes | List of specific flight identifiers from search results (e.g., ['W95730:RC:2025-07-20 04:45:00:0X1']) |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark the tool as read-only and non-destructive. The description adds that it only generates a link and that users must still 'complete their flight reservation', making clear no booking is created by this call. This is useful beyond the structured annotations.
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?
Two short sentences front-load the core action ('Generate booking URL') and add only the essential elaboration about pre-filled criteria and user completion. 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?
For a one-parameter tool with no output schema, the description clearly identifies the output as a URL and explains its purpose. It lacks details such as URL expiration or error behavior, but those are not critical for correct invocation.
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?
The schema already documents the single flight_ids parameter at 100% coverage, including the format and example. The description's mention of 'selected flights' only restates the parameter's role and does not add new semantic detail, so baseline 3 is appropriate.
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 uses a specific verb-resource pair ('Generate booking URL') and limits scope to flight options, setting it apart from flight_search and car_allocate. The second sentence reinforces the purpose: a personalized link to complete a flight reservation.
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?
The phrase 'selected flight options' and 'selected flights' give clear context that this tool is used after flight search/selection. It does not explicitly name alternatives or give when-not-to-use conditions, but the intended workflow is apparent.
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 combination of travel vertical (flight, bus, car, hotel) and action (search, allocate, weather, room details). The weather forecast tools are separated by transport mode with different condition types, so an agent can reliably choose the right one.
Most tools follow a clear resource_action pattern such as bus_search, flight_allocate, and hotel_weather_forecast. Minor deviations are hotel_room_detail, which uses a noun phrase, and mcp_enuygun_ping, which breaks the pattern but is a standard connectivity check.
Twelve tools is a reasonable size for a multi-vertical travel booking server covering flights, buses, cars, hotels, and weather. Each vertical has search and weather coverage, with allocation and detail tools where most relevant.
Flight and car searches have matching allocation tools, but bus_search has no bus allocation/booking tool and hotel_search/hotel_room_detail have no hotel booking allocation tool. The core search and planning surface is present, but the booking lifecycle is inconsistent across verticals.
