C2.8/5.0
Behavior2/5

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

Annotations mark this as destructive (destructiveHint: true), so the description must disclose mutation effects. The description only says 'Edit' with no details on what changes occur, whether it overwrites all attributes, or if it requires specific authorization. It adds no behavioral context beyond the annotation.

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

Conciseness3/5

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

The description is a single sentence that is easy to parse, but it largely restates the title and adds minimal value. It is not verbose, but it could be more informative without losing conciseness.

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 a destructive mutation tool, no output schema, and a nested request body, the description lacks essential operational details: how to construct the body, what response to expect, and any side effects. The schema provides some parameter names but no guidance on usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the tool description does not explain any parameters. It mentions 'attributes' generically but doesn't specify that updatePtrRecordBody contains the new ptr value or that ipAddress is the record identifier. The ptr field within the schema has a minimal description, but the tool description contributes nothing.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses 'Edit' as a specific verb and identifies the PTR Record resource and ip address as key. It distinguishes from sibling tools like createPtrRecord and deletePtrRecord by indicating modification semantics, though it doesn't explicitly name alternatives.

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?

The description implies this tool is for editing an existing PTR record, which is the correct context. However, it provides no explicit when-to-use guidance, no mention of prerequisites (e.g., record must exist), and no comparison with alternatives like updateDnsZoneRecord.

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.
