The name suggests it does something with Resemble's product; it does not. What it is good for is stopping an agent guessing at API shapes from memory, which is where most integration bugs start. Connect it while writing the integration, and expect nothing from it afterwards. It runs on a generic documentation server, so the behaviour will be familiar if you have used one from another vendor.
A documentation search endpoint, not a product one. It answers questions about Resemble's voice API rather than doing anything with voices — useful when a coding agent is writing against that API.
searchDocs — a query against the documentation, returning relevant passages with source links.
