MCP cldkctl Server

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

No annotations are provided, so the description carries full burden but offers no behavioral details. It doesn't disclose if this is a read-only operation, potential side effects, authentication requirements, rate limits, or output format. The phrase 'Call the endpoint' is generic and adds no useful context beyond the tool name.

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 single sentence 'Call the cldkctl_vm_list endpoint' is concise but under-specified, failing to convey essential purpose or usage. It lacks front-loaded information and wastes the opportunity to provide meaningful guidance, making it inefficient rather than appropriately brief.

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?

Given no annotations, no output schema, and a generic description, this is completely inadequate for a tool with 2 required parameters. It doesn't explain what the tool returns (e.g., a list of VMs), behavioral traits, or how it fits among siblings, leaving significant gaps for an AI agent to understand and use it correctly.

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 100%, with clear parameter documentation (project_id and limit, including note on '-1 for all'). The description adds no additional parameter semantics beyond what the schema provides, so the baseline score of 3 is appropriate as the schema adequately covers the parameters.

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 'Call the cldkctl_vm_list endpoint' is a tautology that restates the tool name with minimal added meaning. It vaguely suggests listing VMs but lacks specificity about what resources are listed (e.g., virtual machines in a cloud platform) and doesn't differentiate from siblings like cldkctl_vm_detail or cldkctl_get_vm, which also handle VM-related operations.

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 provided on when to use this tool versus alternatives. With many sibling tools (e.g., cldkctl_vm_detail for detailed VM info, cldkctl_get_vm for specific VM retrieval), the description fails to indicate this tool's role as a list operation or any prerequisites like authentication context.

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