Tastytrade — the complete, unedited output of the deterministic mcptrustchecker engine v1.12.1, scanned . Every finding, capability tag and score component below is exactly what the engine produced — no AI, no post-processing.

"Tools were statically extracted from the published source (46 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command \"npx -y <package>\"."
