This page shows how ABNF rule count, body discarded (io.github.sadri-dridi/abnf-ok)'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: 31 tools. Above 25, models start to tell tools apart less well.
- Critical: These tools share the same description: browser-url-ok, playwright-url-ok.
- 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.
