+#### Notes
+
+- This release registers the official China-site MCP endpoint; the model API --base-url does not change the MCP endpoint.
+- The resolved API key is written to the selected Agent's private local configuration. Existing unmanaged entries are never overwritten.
+- qoder, qoderwork, and qwenwork are independent products. qwenwork is QwenWork (千问办公); qoderwork is Qoder Work.
+- workbuddy covers CodeBuddy / WorkBuddy. deepseek-harness is DeepSeek Harness and only accepts streamable-http.

+bl mcp connect --server TextGenerateImage --transport streamable-http --agent cursor

+bl mcp connect --server VideoGenerate --transport sse --agent claude-code
