resy_list_payment_methods

Read-only

Retrieve the payment methods saved to your Resy account, including card brand, last four digits, expiry, and default status. Use the returned payment method ID when booking a reservation.

Instructions

List the user's saved payment methods on Resy. Returns id, brand, last four digits, expiry, and is_default. The id can be passed as payment_method_id to resy_book.

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 Resy's payload untouched. No field projection: this server has no verified record of which Resy fields matter, and inventing one would risk dropping a field a caller needs.

TDQS

A4.1/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds the return field set and downstream integration with resy_book, which is useful, but it does not disclose additional behavioral traits such as authentication requirements, rate limits, or what happens when no payment methods are saved. Given the read-only annotation, a middle score is appropriate.

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 two short sentences with no filler. It front-loads the core purpose and immediately gives the most important return fields and reuse context, so every clause earns its place.

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 simple, read-only list operation with one well-documented optional parameter and no output schema, the description covers purpose, return fields, and the key integration use case. Nothing essential for an agent to call this tool correctly is missing.

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 coverage is 100%, and the view parameter's description in the schema is already detailed and self-explanatory. The tool description does not add any parameter-level meaning, so the baseline of 3 applies.

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 uses a specific verb ('List') and resource ('the user's saved payment methods on Resy'), and enumerates the exact returned fields (id, brand, last four digits, expiry, is_default). This clearly differentiates it from sibling list tools like resy_list_reservations and resy_list_favorites.

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 provides clear context by explaining that the returned id can be passed as payment_method_id to resy_book, effectively stating when this tool is useful. It does not explicitly name alternatives or exclusions, but no direct alternative for listing payment methods exists among the siblings.

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