TDQS
Scored across 3 tools
The tool names 'generate-auth-code' and 'generate-endpoint-code' both involve 'generate' and 'code', which could be confused without descriptions. 'search-api-docs' is distinct, but the two generate tools overlap in purpose.
All tool names follow a consistent verb_noun pattern using snake_case (generate-auth-code, generate-endpoint-code, search-api-docs). Minor deduction for two tools sharing the same verb 'generate'.
With only 3 tools, this server is extremely limited for an API platform like Nylas. The tool count feels far too low for the expected scope.
The tools are limited to code generation and documentation search, leaving out all core API operations (e.g., sending emails, managing calendars). This is a severe gap.
