IONOS CLOUD MCP Server

Official

list_server_volumes

Retrieve all volumes attached to a server by providing the data center and server IDs.

Instructions

List all volumes attached to a specific server

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
depthNonesting depth of returned objects (0-5, default 1)
filtersNoserver-side filters as property→value pairs (contains match); e.g. {"name":"prod"} If the result is empty, retry without filters — a filter typo or mismatch silently returns nothing.
server_idYesthe ID of the server
datacenter_idYesthe ID of the data center
Behavior2/5

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

No annotations provided, yet the description does not mention read-only nature, pagination, error behavior, or what the response contains. Only the basic operation is stated, leaving critical behavioral traits undisclosed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, front-loading the purpose. It is efficient, but could include more context without being verbose.

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

Completeness2/5

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

With 4 parameters, no output schema, and annotations absent, the description is too sparse. It omits return format, filtering behavior, depth usage, and error handling, making it incomplete for an AI agent to use reliably.

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?

All 4 parameters have schema descriptions (100% coverage). The description adds no extra meaning beyond stating 'specific server', so baseline 3 is appropriate.

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 clearly states the verb 'List' and the resource 'volumes', scoped to 'a specific server'. This differentiates it from sibling tools like list_volumes (all volumes) and get_volume (single volume).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use or alternatives. Users must infer from the description that it's for server-scoped volume listing, but no when-not-to-use or comparison with list_volumes.

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