-}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the description adds little. It mentions 'all data centers' and 'regions' but does not describe pagination, filtering defaults, or any other behavioral traits. No contradiction, but minimal value beyond annotations.
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 short and front-loaded. However, the prefix 'List data centers -' repeats the tool name and adds no value, slightly detracting from conciseness.
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?
With 9 parameters and no output schema, the description is under-specified. It does not mention required x-request-id, pagination, filtering, or ordering behavior. The tool is safe to call (per annotations), but the description alone is insufficient for correct invocation.
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?
Schema description coverage is 0%, so the description must compensate. It only hints at region-related parameters via 'corresponding regions' but leaves page, size, orderBy, name, slug, and tracing parameters unexplained. This is insufficient for a 9-parameter tool.
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 action ('List') and the resource ('data centers'), and adds that it returns corresponding regions. This distinguishes it from sibling tools, as it is the only one about data centers.
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?
Usage is implied by the name and description, but there is no explicit guidance on when to use this tool over alternatives or any prerequisites. No alternatives are mentioned, but the purpose is clear enough that an agent can infer when to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
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.
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.
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.
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.
