## Summary Follow-up to #3056 This PR updates the mcp-server interface for reading the config settings saved by the user. At risk of introducing _another_ Config struct, I think it makes sense to avoid tying our protocol to ConfigToml, as its become a bit unwieldy. GetConfigTomlResponse was a de-facto struct for this already - better to make it explicit, in my opinion. This is technically a breaking change of the mcp-server protocol, but given the previous interface was introduced so recently in #2725, and we have not yet even started to call it, I propose proceeding with the breaking change - but am open to preserving the old endpoint. ## Testing - [x] Added additional integration test coverage
