KOLSprite Caption

Access caption_extract_url through the active compatible KOLSprite connection, either as a directly exposed business tool or through the Yunya facade. Do not ask whether to use MCP.

Compatible MCP routing

• Prefer the SellerSpace Yunya unified MCP when it is available and authenticated.
• Support direct business tools plus current and legacy Yunya facade entrypoints.
• In direct mode, resolve and call caption_extract_url by its semantic business name.
• In Yunya facade mode, if the business tool is not visible at the host's top level, make at most one host-level discovery attempt and prefer the product-specific yunya_search_kolsprite_tools. Call it once with the TikTok-caption-extraction intent; use the exact internal tool name and complete input schema it returns, then invoke that tool through call_read_tool.
• If the product-specific entrypoint is unavailable but the legacy generic yunya__search_tools is discoverable, call it once with provider kolsprite, operation read, and the same caption intent. Do not prefer the generic entrypoint when the product-specific one is available.
• Do not guess a facade namespace, internal tool name, wrapper, or arguments. Reuse the discovered name and schema for the run.
• A host-level miss for caption_extract_url does not prove that the internal business tool is absent. Only report a missing business dependency after direct exposure and the available current or legacy facade lookup fail. If neither facade entrypoint can be discovered, report a connector-discovery failure and do not switch to Feishu Minutes or another unrelated fallback service.
• A standalone KOLSprite MCP remains compatible only when it exposes the same required semantic tool name, input schema, and response shape.
• If both connections are enabled, use one connection for the entire run, prefer Yunya, and never duplicate a paid call across both services.
• If caption_extract_url is absent or schema-incompatible, report the missing dependency instead of substituting another caption tool name.
