Outscraper Ping

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

Annotations are absent, so the description carries the full burden. It clearly states the behavior: checks server status and returns metadata. While it doesn't elaborate on error behavior or metadata structure, it adds value beyond the name by specifying the action and output, enough for a simple ping tool.

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 concise and front-loaded with the core purpose, followed by a focused bullet list of use cases. Every sentence adds value with no redundancy or filler.

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 tool's simplicity, the absence of parameters, and the existence of an output schema, the description is fully complete. It covers what the tool does and when to use it, and the output schema handles return-value expectations. No additional detail is necessary.

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 tool has zero parameters, so the baseline is 4. The description appropriately avoids mentioning parameters since none exist, and there is no additional semantic burden to carry.

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 uses a specific verb ('Check') and identifies the resource ('whether the Outscraper MCP server is running'), clearly distinguishing it from data-fetching siblings. It also mentions returning metadata, making the tool's function unambiguous.

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 'Best for' section explicitly lists three concrete use cases: validating startup, confirming reachability, and lightweight health checks. It gives clear context for when to use this tool, though it doesn't explicitly mention when not to use it or alternatives, which is acceptable for a health check utility.

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