Deliverable: Retriever over MCP: expose your T6 retriever as an MCP tool and call it from an MCP client chatbot.
Assessment: Answer the five Interview questions without notes, then run the lab.
Interview probe: Larkspur's support bot connects to a filesystem server rooted at the project folder. Someone adds a second filesystem server rooted at `./handbook`. Now the bot says files it read yesterday “do not exist”. How do you find the cause?
Common mistakes: Putting parameter limits in docstring Args: lines instead of the type
Connecting two servers whose tool names collide in tool_to_session
Relying on FastMCP's default host inside a Docker container
