Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@calculator-mcp-server calculate 5 + 3"
That's it! The server will respond to your query, and you can continue using it as needed.

TDQS
B3.2/5.0
Scored across 2 tools
Disambiguation5/5
The two tools, 'calculate' and 'convert_temperature', have clearly distinct purposes with no overlap. An agent can easily select the appropriate tool based on the task.
Naming Consistency5/5
Both tool names follow a consistent verb_noun pattern: 'calculate' (verb) and 'convert_temperature' (verb_noun). The naming is predictable and clear.
Tool Count4/5
With only 2 tools, the set is minimal but still reasonable for a focused calculator server. It covers core arithmetic calculation and temperature conversion without unnecessary clutter.
Completeness3/5
The tool surface covers basic arithmetic and temperature conversion, but lacks other common calculator operations like exponentiation, trigonometry, or memory functions, leaving notable gaps for a general-purpose calculator.
