MCP Kafka Schema Reg

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

No annotations are provided, so the description carries the full burden. It mentions the tool is 'interactive' and will 'elicit' preferences, which hints at user interaction, but fails to disclose critical behavioral traits: whether it's read-only or destructive (export might imply read-only, but not confirmed), authentication needs, rate limits, or what happens during elicitation (e.g., prompts, timeouts). For a tool with 8 parameters and no annotations, this leaves significant gaps in understanding its operation.

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 appropriately sized with two sentences that are front-loaded: the first states the purpose, and the second clarifies usage. There's no wasted text, and it efficiently conveys key points. However, it could be slightly more structured by explicitly listing what 'global' entails, but overall, it's concise and well-organized.

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 (8 parameters, 0% schema coverage, no annotations, no output schema), the description is incomplete. It lacks details on what 'global export' includes, how elicitation works, the tool's safety profile, and the meaning of parameters. Without this information, an AI agent would struggle to use the tool correctly, making it insufficient for the tool's scope and parameter richness.

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%, meaning none of the 8 parameters have descriptions in the schema. The description only vaguely references 'export preferences' without explaining what the parameters (e.g., compression, format, include_config) mean or how they affect the export. It adds minimal semantic value beyond implying parameters relate to preferences, failing to compensate for the lack of schema documentation, which is inadequate given the high parameter count.

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 performs an 'interactive global export with elicitation for export preferences', which indicates it exports data globally and interactively gathers preferences. However, it's vague about what 'global export' means (e.g., all schemas, contexts, or other resources) and doesn't distinguish it from sibling tools like 'export_global' (non-interactive) or 'export_context', leaving ambiguity in its specific scope.

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 provides clear context for when to use this tool: 'When export preferences are not specified, this tool will elicit the required configuration from the user.' This implies it's suitable for cases where preferences are unknown or need user input, offering guidance on its interactive nature. However, it doesn't explicitly state when not to use it (e.g., vs. 'export_global' for predefined preferences) or mention alternatives, which limits full differentiation.

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