Conekta MCP Server

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool retrieves a checkout by ID but lacks details on permissions, rate limits, error handling, or response format. While it implies a read operation, it doesn't confirm safety or other behavioral traits beyond the basic action.

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 front-loaded with the core purpose in the first sentence, followed by a brief, structured 'Args' section. Every sentence earns its place by directly supporting tool understanding, with no redundant or verbose content. It is appropriately sized for a simple retrieval tool.

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 low complexity (single parameter, no nested objects) and the presence of an output schema (which handles return values), the description is mostly complete. It covers the purpose and parameter semantics well. However, it lacks behavioral details like error cases or usage context, which would be beneficial despite the output schema.

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 description adds meaningful context for the single parameter 'checkout_id' by specifying it as 'The Conekta checkout ID', which clarifies the expected format and source beyond the schema's minimal title ('Checkout Id'). With 0% schema description coverage and only one parameter, this compensates adequately, though it could provide more detail (e.g., ID format examples).

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 specific action ('Get') and resource ('a payment link (checkout) by ID'), distinguishing it from sibling tools like 'list_checkouts' (which lists multiple) or 'create_checkout' (which creates one). It precisely defines what the tool does without being vague or tautological.

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 description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., needing a checkout ID), exclusions, or comparisons to siblings like 'list_checkouts' for browsing or 'get_order' for related resources. Usage is implied but not explicitly stated.

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