This page shows how io.github.dtajitdinov-aris/sphere-marketplace'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.

## Across the server

- Minor: 30 tools. Above 25, models start to tell tools apart less well.
- Minor: 18 pairs with nearly the same description in all; the top 12 are shown.
- Minor: The server's instructions are 7186 characters. Claude Code reads only the first 2,048 by default (Codex 0.154.0 reads them whole). Put what the server is for first.
