Pass tool_ids as a URL query parameter (comma-separated) to include Open WebUI tool IDs (e.g. MCP servers) in chat completion requests. This enables MCP tool activation when the widget is embedded. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The non-streaming /api/chat/completions endpoint doesn't execute Open WebUI's MCP tool pipeline. Streaming mode enables tool context injection and provides real-time response rendering. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Fix conversation context bug: send full message history instead of only last message - Add welcome screen with icon, title, subtitle, and 3 suggested prompts - Add configurable title via 'title' URL param (defaults to 'GCP Cost Assistant') - Add 'New chat' button to clear conversation - Switch to Google Blue (#4285f4) color scheme - Styled send button with blue background - Better placeholder: 'Ask about GCP costs and pricing...' - Chat bubble icon instead of layers icon Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Reads 'prompts' query parameter as pipe-separated list of prompts. Falls back to hardcoded defaults when not provided. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
