cliffhall 07cafeedbc feat: surface and decode the OAuth id_token in Connection Info (#2019) 
When an authorization server returns an `id_token` alongside the access
token, the Inspector already persisted it and never showed it. Wire it
through to Connection Info as a viewer.

- Generalize `OAuthAccessTokenField` into `OAuthTokenField` (label + token),
  so the ID Token row reuses the existing copy control and "Decode JWT"
  toggle rather than duplicating them. Access-token behavior is unchanged.
- `oauthDetailsFromConnectionState` now surfaces `tokens.id_token` as
  `idToken`, omitted entirely when absent so no empty row renders.
- Docs: update the two `specification/` references to the renamed field.

This is deliberately a viewer, not a flow: no OIDC login mode, no signature
verification, and the `id_token` is never treated as a credential. The EMA
path is untouched. `id_token` is already in `maskSecrets`'
`JSON_SENSITIVE_KEYS`, so it stays masked in the Network tab — no gap.

## Design Principles
- **Single server connection** - No multiple concurrent connections (defer to plugins)
- **MCPJam-inspired** - Use MCPJam Inspector as UX reference model
- **Full-width content** - Maximize screen real estate for each section
- **No sidebar** - Deferred until menu becomes cumbersome or extensions multiply
- **Progressive disclosure** - Show relevant information at each connection stage
- **Resizable panels** - Allow users to adjust panel sizes on feature screens
## Navigation Model
```
┌─────────────────────────────────────────────────────────────────────────────────────────┐
│ [Server Name ▼] ● Connected (23ms) [Tools] [Apps] [Resources] [Prompts] [Logs] [Tasks] [History] [Disconnect] │
├─────────────────────────────────────────────────────────────────────────────────────────┤
│ │
│ Full-width content │
│ │
└─────────────────────────────────────────────────────────────────────────────────────────┘
```
- **Menu bar** displays server name, connection status with latency, and disconnect button when connected
- **Top navigation** links to Tools, Apps, Resources, Prompts, Logs, Tasks, and History sections
- **Connection indicator** shows latency from periodic `ping` requests
- **No sidebar** - content areas use full width
## Screen Flows
### Server List (Home)
Initial screen shown when no server is connected. Displays server cards in a responsive grid (1-2 columns).
```
┌─────────────────────────────────────────────────────────┐
│ MCP Inspector │

└─────────────────────────────────────────────────────────┘
```
**Add Server Options:**
- **Add manually** - Opens form modal for manual configuration
- **Import config** - Paste/upload internal `mcp.json` config
- **Import server.json** - Import MCP Registry format ([Issue #922](https://github.com/modelcontextprotocol/inspector/issues/922))
**Functionality:**
- List servers from `mcp.json` config file
- Add/edit/delete servers via CRUD endpoints on proxy
- Responsive grid layout (1 column mobile, 2 columns desktop)
### Server Connection Card
Each server in the list is displayed as a card with connection controls and status.
```
┌─────────────────────────────────────────────────────────┐

|--------|-----------|---------|
| Connected | Green dot | "Connected" |
| Connecting | Yellow pulsing dot | "Connecting..." |
| Failed | Red dot | "Failed (N)" with retry count |
| Disconnected | Gray dot | "Disconnected" |
**Card Actions:**
- **Toggle switch** - Connect/disconnect the server
- **Copy** - Copy command/URL to clipboard
- **Server Info** - Opens server info modal
- **Edit** - Opens edit server modal
- **Remove** - Deletes server (with confirmation)
### Import server.json Modal

```
**Schema Validation:**
- Validate against official MCP Registry schema
- Show validation errors inline with line numbers
- Highlight issues in the JSON editor
**Package Selection:**
- If server.json contains multiple packages (npm + pypi), let user choose which to use
- Display registry type, identifier, and runtime hint for each option
**Environment Variables:**
- Parse `environmentVariables` array from selected package
- Generate form fields for each variable
- Mark required variables with asterisk (*)
- Show description as helper text
- Validate required variables are filled before enabling "Add Server"
**Value Verification:**
- Check if package exists in registry (npm, pypi)
- Verify environment variables are set (or prompt user)
- For HTTP transport: optionally verify URL is reachable
- For STDIO: verify command is available (e.g., `npx` installed)
**Server Generation:**
- Convert server.json to internal config format
- Construct command from runtime hint + package identifier (e.g., `npx -y my-mcp-server`)
- Apply environment variables
- Set transport type from package.transport
**server.json to Internal Config Mapping:**
| server.json Field | Internal Config Field |
|-------------------|----------------------|
| `name` | `name` (display name) |
| `packages[n].registryType` | Determines command prefix |
| `packages[n].identifier` | Package name in command |
| `packages[n].runtimeHint` | Command prefix (npx, uvx, etc.) |
| `packages[n].transport.type` | `transportType` |
| `packages[n].environmentVariables` | `env` object |
**Use Cases:**
1. MCP authors testing server.json before publishing to registry
2. Developers importing servers from registry without manual setup
3. Configuration troubleshooting with detailed validation feedback

#### Apps Screen
A two-panel layout showing the subset of tools that are **MCP Apps** — tools whose
metadata advertises a UI resource via `_meta.ui.resourceUri` (or the deprecated
flat `_meta["ui/resourceUri"]`). The right panel toggles between an input form
(before launch) and the embedded app (after launch).
**Input Form State:**
```
┌──────────────────────────┬──────────────────────────────────────────────┐

└──────────────────────────┴──────────────────────────────────────────────┘
```
**Running App State:**
After "Open App" the right panel swaps to the embedded MCP App. The input
form is replaced by the app iframe; a "Back to Input" button (only when the
selected app has input fields) returns to the form.
```

```
**Features:**
- **App Detection** — A tool is treated as an App when `getToolUiResourceUri(tool)`
returns a defined `ui://...` URI (helper from `@modelcontextprotocol/ext-apps`).
Filtering happens upstream (wiring layer); the screen receives an already-filtered
`tools: Tool[]` array of apps.
- **List Changed Indicator** — Shows when `notifications/tools/list_changed` received.
- **Refresh Apps** button re-runs `tools/list`.
- Searchable list, mirroring the Tools screen sidebar.
- **App icons** rendered from `tool.icons` when present.
- **App Input form** generated from `tool.inputSchema` (same `SchemaForm` used by
Tools screen).
- **Open App** button:
- If the tool has input fields, the form must be filled before launch.
- If the tool has no input fields, "Open App" runs immediately on selection.
- **Back to Input** returns to the form (only visible when the app has fields).
- **Maximize / Minimize** toggle hides the sidebar to give the app the full viewport.
- **App Renderer** embeds the UI resource in a sandboxed iframe and bridges
it to the active MCP server via `AppBridge`. Tool input and result are sent
to the app via `sendToolInput` / `sendToolResult`.
- **Close (✕)** deselects the app and clears any in-flight launch.

### Client Feature Handlers
Client feature handlers manage server-initiated requests (sampling, elicitation). They appear in two contexts:
1. **Inline** - When triggered during tool execution, shown within the Tools screen (see [Inline Client Request Queue](#tools-screen))
2. **Modal** - For standalone testing or detailed view
For detailed documentation including Testing Profiles and Sampling Providers, see [v2_ux_handlers.md](v2_ux_handlers.md).

## Form Generation
Forms are dynamically generated from JSON Schema for tool inputs, prompt arguments, and resource template variables.
**Supported Field Types:**
| JSON Schema Type | Form Control |
|------------------|--------------|
| `string` | Text input |
| `string` (enum) | Select dropdown |
| `string` (format: uri) | URL input with validation |
| `number` / `integer` | Number input |
| `boolean` | Checkbox or toggle |
| `array` | Dynamic list with add/remove |
| `object` | Nested fieldset |
**Schema Features:**
- `required` - Mark fields as required (*)
- `default` - Pre-fill with default value
- `description` - Show as helper text
- `enum` - Render as select dropdown
- `minimum` / `maximum` - Validation for numbers
- `minLength` / `maxLength` - Validation for strings
**Fallback:**
- For complex schemas (`anyOf`, `oneOf`, `$ref`), show JSON editor as fallback
- Toggle between form view and JSON editor
## Error Handling UX
### Toast Notifications
Transient errors and success messages shown as toasts:
```
┌─────────────────────────────────────────────────────────┐
│ ✓ Connected to everything-server [×] │
└─────────────────────────────────────────────────────────┘
┌─────────────────────────────────────────────────────────┐
│ [!] Tool execution failed: Invalid parameters [x] │
│ [View Documentation →] │
└─────────────────────────────────────────────────────────┘
```
### Inline Error Display
Persistent errors shown inline in context (e.g., server cards):
```
┌─────────────────────────────────────────────────────────┐
│ [!] Connection Error │
│ │
│ Failed to connect: ECONNREFUSED │
│ Retry attempt 3 of 5 │
│ │
│ [Show full error] [Troubleshooting Guide →] │
└─────────────────────────────────────────────────────────┘
```
**Error Display Patterns:**
- **Truncation** - Long errors truncated to ~100 chars with "Show more"
- **Retry count** - Display retry attempts for connection errors
- **Doc links** - Contextual links to troubleshooting documentation
- **Expandable** - Click to show full error message/stack trace
### Connection States
Clear visual feedback for connection lifecycle:
| State | Visual | User Action |
|-------|--------|-------------|
| Disconnected | Gray status, toggle off | Click toggle to connect |
| Connecting | Yellow pulsing, spinner | Wait or cancel |
| Connected | Green status, toggle on | Click toggle to disconnect |
| Failed | Red status, error shown | Retry or edit config |
| OAuth Flow | Redirect indicator | Complete OAuth in browser |
