Porkbun MCP Server

update_auto_renew

Idempotent

Turn auto-renewal on or off for a domain to automate payment at expiration or require manual renewal.

Instructions

Turn auto-renewal on or off for a domain in the authenticated account. When auto-renew is on, Porkbun automatically charges your account credit at expiration. When off, you must manually renew or the domain expires. Idempotent.

Input Schema

statusYes`on` enables auto-renew, `off` disables it.
Behavior4/5

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

Beyond annotations (idempotentHint=true), the description adds that turning auto-renew on charges account credit, and turning it off requires manual renewal. This provides valuable behavioral context not present in annotations.

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?

Three short sentences, no redundancy. The first sentence states purpose, the second explains consequences, and the third states idempotency. Every sentence earns its place.

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

Completeness4/5

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

The tool is simple with only two parameters and clear behavior. The description covers purpose and consequences, but lacks information about return values or prerequisites (e.g., domain must exist). Still sufficient for the simple operation.

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 both parameters are described in the schema. The description does not add additional meaning beyond the schema's descriptions, so baseline score 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 ('Turn auto-renewal on or off') and resource ('for a domain in the authenticated account'), clearly distinguishing it from sibling tools like register_domain or update_dns_record.

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 explains the consequence of auto-renew being on (automatic charge) and off (manual renewal), giving context for when to toggle. It doesn't explicitly state when not to use it, but the context is clear.

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