feat(web-ui): UI polish + MCP OAuth handling#643
Merged
Conversation
- Layout: gray canvas + floating rounded main panel; sidebar transparent on canvas (login page framed); lighter gray backdrop; no shadows. - Account block moved to the sidebar footer (out of the navbar top-right). - Hide the actions/timestamp row while a turn is thinking/streaming; show a fallback note when a finalized turn has no visible content. - Login: reserve the hint line so an invalid username no longer shifts the input. - Session list items get spacing between rows. - Default agent selection prefers a servable conversational agent (web_search_agent / web_demo) instead of a non-loadable numbered example. - MCP / tool OAuth: parse the `adk_request_credential` event into an auth card, open the authorize URL, capture the callback, and resume the run via a function response (blocks.ts + Blocks.tsx AuthCard + client runSSE resume + App). - examples/web_search_agent: a servable non-a2ui agent with the web_search tool.
- collapse the authorization card to a compact "已授权 · <toolset>" row the moment the callback returns, instead of holding "等待授权…" until the whole reply finishes streaming - amber shield while pending, green once authorized; card names the toolset and the identity provider it will redirect to; wider layout - auto-capture the OAuth popup callback at the app entry (postMessage to the opener + close) so the user never pastes the callback URL - hide a turn's actions/timestamp row while it is awaiting authorization - add examples/mcp_oauth_agent: an MCP tool guarded by ADK-native OIDC OAuth (OpenIdConnectWithConfig + client credentials on McpToolset), fully env-driven, with a README
…d origin Default OIDC_REDIRECT_URI to http://localhost:8000/ (where `veadk frontend` serves the UI) instead of the Vite dev port; note the :5173 dev alternative in the agent docstring and README.

adk_request_credentialflow:blocks.ts: parse the credential-requestfunctionCallinto a dedicatedauthblock (callId, authUri, authConfig); resolve it on the credential response; skip empty function-response user turns on replay.Blocks.tsx: an OAuth card ("该工具需要授权" + 去授权 button, with authorizing/done/error states).client.ts:runSSEacceptsfunctionResponsesto resume a long-running call.App.tsx:onAuthopens the authorize URL in a popup, captures the callback (same-origin poll + postMessage, with a paste-URL fallback), setsoauth2.authResponseUri, and posts the credential back — the resumed run streams into the same turn.Example

veadk/webuibundle is rebuilt from this source. Excludes theweb_fetchtool (that's in #586). MCP-OAuth was validated for event parsing/rendering/build; a live token exchange still needs a real MCP-OAuth tool to test against.🤖 Generated with Claude Code
