The success response is now built by `dashboard_serializer` — the same serializer `get_dashboard_info` uses — so all user-controlled strings (title, description, css, certification fields, tag/chart names) are wrapped in untrusted-content delimiters before reaching the LLM, giving full parity with the read path. The minimal re-fetch fallback also runs its title through `sanitize_for_llm_context`. ########## superset/mcp_service/dashboard/tool/update_dashboard.py: ########## @@ -0,0 +1,363 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.

The scalar attributes (id, dashboard_title, published) are now captured into locals *before* the re-fetch, and the fallback response uses those locals instead of re-reading ORM attributes that may have been expired by the post-commit session invalidation. Serialization also moved inside the try, so a lazy-load failure during serialization is caught by the same handler. ########## superset/mcp_service/dashboard/tool/update_dashboard.py: ########## @@ -0,0 +1,363 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.
