CAUTION

Publisher claims: "Read-only MCP server (stdio): GPU rental price comparison checked daily (H100, H200, A100, L40S, RTX 4090/5090 and more) with price history, a stack cost optimizer, and AI-infra deals and free tiers." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

What would make this Verified

20 points to 80 · weights: behavior 45%, static 25%, prompt 15%, publisher 15%
  1. Unclaimed publisher≈ +8 on the totalClaim connormatthewdouglas: a verified publisher gets +50 on publisher trust. It is free and usually instant with GitHub sign-in.
  2. Does not do what the description says≈ +5 on the totalIn the sandbox the skill never performed the task it claims (no call to the service it is for). Make sure the happy path runs without extra setup, or describe the real behavior.
  3. New publisher≈ +3 on the totalTime clears this on its own after 14 and 30 days. Claiming the handle (+50) is the fastest way past it.
  4. Unicode escape sequence detected≈ +2 on the totalPut hosts, commands and strings in plain source. Decoding at runtime looks identical to malware and costs points on its own.
