Scores, issues and names only

This page shows how dev.coinop/longwatch's tool descriptions scored, the issues found and the names of its tools and parameters. The descriptions are the server's own: read them where the copy came from.

Forecall asked the URL this server lists in the official MCP Registry for its tools/list once, on the date above, without calling any tool. The server may have changed since.

Average score: 56.6 / 100Cloudy
Tools: 18
Near-identical descriptions: 1

Across the server

Major
14 tools repeat the same note (34 words). Say it once in the server's instructions, and let each description say what only that tool does. The note does not count toward the tools' scores.repeated_note
Minor
The server has no instructions. Say there, once, what the server is for and when to use it: Claude Code and Gemini CLI read the instructions before the tool descriptions.instructions_missing

Tools whose descriptions are nearly the same

What static scoring cannot tell

This score reads only the text of each description and schema: it says what is written, not what a model will do. Short tools whose names already say what they do, such as browser_close, score low here even when models use them well, and in our measurements current models chose the right tool in one step even from one-line descriptions, as long as the names and schemas differed. What the text cannot show, such as what happens over several steps and whether an added sentence helps or misleads, is what an evaluation measures, on the Pro and Team plans.
