This page shows how DropEngine x402 Agent Services (io.github.Ahmet11159/x402-agent-services)'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: 24 tools repeat the same note (90 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 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.
