Is bot.mailbox/mailbox safe to use?
bot.mailbox/mailbox scores 79/100 — grade B, which is a solid posture with a few gaps worth reading. It passes 5 of the 9 OWASP MCP Top-10 checks that apply to it, with Missing Authentication, Lack of Audit and Telemetry, Inadequate Rate Limiting, and Supply Chain Risk returning a warning rather than a pass. 1 further check does not apply to this server's transport and is excluded from the score entirely — skipped is not the same as failed. This is what the scanner found on 2026-08-06, not a guarantee. Re-run it yourself with `npx mcpr scan`.
What a grade B means, the ten checks behind it, and the point maths are all on how we score MCP server trust.
