How would you verify that text metadata is properly attached and accessible after integrating an MCP into deployment? What steps would you take to confirm this?

First, I would identify the metadata schema expected by downstream consumers (e.g., key names, data types, required fields). Then I would write integration tests that simulate the MCP pipeline: feed sample text into the MCP, capture the output, and assert that the metadata fields are present and correctly formatted. For runtime verification, I would enable logging at the point where metadata is attached, capturing a sample payload to a monitoring dashboard. Additionally, I would perform a health‑check endpoint that returns the metadata for a test document, allowing manual or automated verification. Finally, I would set up a monitoring rule that flags any missing or malformed metadata in production logs, ensuring continuous compliance. This approach covers unit, integration, and production‑level validation, giving confidence that metadata is correctly attached and accessible.
