MCP cldkctl Server

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

No annotations are provided, so the description must fully disclose behavioral traits. The description fails to indicate whether this is a read or write operation, what permissions are required, or any side effects (e.g., rate limits, data returned). It doesn't explain what 'available_member' means in context, leaving the agent guessing about the tool's 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 a single sentence that is overly concise to the point of being uninformative. While it avoids verbosity, it fails to convey essential information, making it under-specified rather than efficiently structured. It doesn't front-load key details, wasting the opportunity to guide the agent effectively.

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 the complexity implied by the tool name (involving registries and members) and the lack of annotations and output schema, the description is completely inadequate. It doesn't explain the tool's function, output format, or behavioral context, leaving the agent unable to use the tool correctly without external knowledge.

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?

The input schema has 100% description coverage, with the single parameter 'project_id' clearly documented. The description adds no additional semantic context about the parameter (e.g., how it relates to registry members or availability). Since the schema does the heavy lifting, the baseline score of 3 is appropriate, though the description contributes no extra value.

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_registry_available_member endpoint' is a tautology that merely restates the tool name without explaining what the tool does. It lacks a specific verb and resource, failing to distinguish this tool from its many siblings (e.g., cldkctl_registry_member_list, cldkctl_registry_member_add). This provides no meaningful information about the tool's purpose.

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?

The description offers no guidance on when to use this tool versus alternatives. With siblings like cldkctl_registry_member_list and cldkctl_registry_member_add, it's unclear if this tool lists, adds, or checks availability of registry members. There is no mention of prerequisites, context, or exclusions, leaving the agent without usage direction.

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