This page shows how R/IV — Verify Claims, Citations & Agent Actions (io.github.duranivrobert-glitch/riv)'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: 35 tools. Above 25, models start to tell tools apart less well.
- Minor: 398 pairs with nearly the same description in all; the top 12 are shown.
- 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.
