-}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, lowering the bar. The description adds that it lists the user's own handles and supports filtering, but omits details like pagination, required request ID, or default behavior.
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 but repetitive: 'List all handles' duplicates the title and the second clause reiterates the same idea. It is concise in length but not in wording, lacking structural clarity.
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?
For a list endpoint with 12 parameters and no output schema, the description does not explain pagination, return format, required headers, or how filters combine. This 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?
With 0% schema parameter coverage, the description must compensate but only says 'filter', implying some parameters are filters without explaining specific ones. It does not clarify orderBy, page, size, search, or showDefaults semantics.
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 states the tool lists and filters handles, using a clear verb and resource. It distinguishes from retrieveHandle (singular) and mutation tools, but is somewhat redundant with the title.
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?
No guidance is given on when to use this tool versus alternatives like retrieveHandle or setDefaultHandle. The description does not mention exclusions or provide context for selecting this over sibling tools.
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.
