This page shows how Agent Utility Suite (x402) (io.github.vanakenj45/x402-agent-api)'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

- Major: 41 tools. Above 40, models choose less accurately.
- Major: 36 tools repeat the same note (30 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.
- Minor: The server's instructions are 7125 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.
