Scored across 1 tool

Disambiguation5/5

Only one tool exists, so there is no possibility of confusion between tools. The tool's purpose is clearly defined and distinct.

Naming Consistency5/5

With a single tool, naming is inherently consistent. The name 'ssl_expiry_checker' is descriptive and follows a clear pattern.

Tool Count3/5

The server has only one tool, which is minimal for its domain. While it serves a focused purpose, it falls short of the typical 3-15 tool range for a well-scoped server.

Completeness4/5

The single tool covers the core functionality of checking SSL certificate expiry for a given URL. However, it lacks additional tools for batch checks, certificate details, or alerting, which would enhance completeness.
