The two tools are clearly distinct: convert performs a transformation action, while list_styles retrieves metadata. There's no overlap in purpose. The only minor concern is that list_styles could arguably be a helper within convert, but as separate tools they're unambiguous.

Both tools use a consistent verb-first snake_case pattern: convert and list_styles. The naming follows a predictable convention with concise, descriptive verbs that clearly indicate the action each tool performs.

With only 2 tools for what appears to be a conversion-focused server, the surface feels quite thin. A tool like this would reasonably benefit from additional tools such as getting validation feedback, converting to different output formats, or inspecting diagrams before conversion. Two tools barely constitutes a functional server.

The core conversion workflow is covered (convert + style discovery), but there are notable gaps. There's no validate/preview tool to check a Mermaid diagram before converting, no way to batch convert multiple diagrams, and no handling for additional diagram types beyond the three mentioned. The surface works for basic usage but has dead ends.
