A3.7/5.0
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, covering the safety profile. The description adds that it returns 'all attributes' and selects by zone name, but does not disclose error behavior, whether a non-existent zone returns 404, or any other operational details. This is adequate for a simple read but not rich.
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 a single, front-loaded sentence: 'Retrieve a DNS Zone by zone name - Get all attributes for a specific DNS Zone'. Every word contributes meaning, with no filler or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read tool with annotations, the description is adequate but incomplete. There is no output schema, and the description only promises 'all attributes' without specifying what those attributes are or how the response is structured. It also does not address edge cases like zone not found. Given the lack of output schema, more detail would be expected.
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 description coverage is 0%, so the description must compensate. It explicitly states the zone is retrieved by zone name, clarifying the role of zoneName. However, it does not explain the required x-request-id or optional x-trace-id headers; their names and patterns (UUID for x-request-id) make them somewhat self-explanatory, but the description adds minimal value for these parameters.
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 the specific verb 'Retrieve' with the resource 'DNS Zone' and specifies 'by zone name' and 'for a specific DNS Zone', clearly distinguishing this from sibling tools like retrieveDnsZonesList (plural list) and retrieveDnsZoneRecordsList.
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?
Usage is implied: use this when you need a specific DNS zone's attributes by its name. However, there are no explicit exclusions or references to alternative tools (e.g., retrieveDnsZonesList for listing), so the guidance is only implied, not explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

C2.2/5.0
Disambiguation2/5
Many tools have clearly distinct CRUD roles per resource, but there are several confusing overlaps: start/stop/restart/shutdown/rescue are similar lifecycle actions, and there are duplicate audit tools like retrieveImageAuditsList and retrieveImageAuditsList1 (one even mislabeled as DNS Zones audit). Additionally, retrieveTagAuditsList appears to duplicate retrieveAssignmentsAuditsList, and updateDnsZoneRecord incorrectly says 'Create resource record'. These overlaps and mislabeled descriptions make it hard to pick the right tool.
Naming Consistency2/5
The naming is a mix of camelCase verb_noun patterns, but inconsistent. Some tools use 'retrieveXList' while others use 'listX', some use 'Cancel' with a capital letter, and 'tool_search' uses snake_case. Numeric suffixes like 'retrieveImageAuditsList1' and verbs like 'patchInstance' instead of 'updateInstance' further break consistency.
Tool Count1/5
With 124 tools, this is an extremely large tool surface for an MCP server. Even for a broad cloud provider API, this overwhelms an agent's context and selection capabilities. The number far exceeds reasonable scoping and creates unnecessary selection overhead.
Completeness4/5
The tool set covers a wide range of resources thoroughly: instances, snapshots, images, private networks, object storage, DNS, domains, tags, roles, users, secrets, and audits. Most resources have create/retrieve/update/delete lifecycle operations, and there are extensive audit history tools. Minor gaps exist (e.g., no explicit instance deletion besides cancel, no separate firewall management beyond upgradeInstance), but overall the surface is quite complete for its domain.
