  Follows MCP best practices (not scored yet)

  2 tips (not scored)

  • !The tool list is about 41 KB (roughly 10k tokens). AI apps send it with every message, so it takes that much of the AI's memory before any work starts.
  • !edit_video_brief: Labeled read-only, but it takes a raw "script" input. A read-only label can't promise much when the tool runs whatever it's sent; make the tool itself refuse changes (for example with a read-only database user), or drop the label. QAmcp doe
