cliffhall 219298b24d feat(web): add Console (stderr) tab; show it on stdio connect failure (#1621)
A failed stdio launch had no useful diagnostic surface: the message log
(History) is cleared on the error transition and there are no HTTP
requests (Network), so the auto-opened monitoring column was empty. The
process's stderr — which explains the failure (e.g. "No module named
mcp_server_time") — was captured in StderrLogState but never displayed.

- New ConsoleScreen renders the captured stderr stream (search / sort /
  clear / export; embeddable in the monitoring column), wired through App
  via the existing useStderrLog hook + StderrLogState.
- Console is a pinnable monitor tab like Logs/History/Network, gated to
  stdio servers (HTTP has no child process). It lives in the header menu
  when the column isn't pinned, and moves into the column when it is.
- The failure column now picks its tabs by which diagnostic actually
  captured content (stderr → Console, fetch requests → Network), not by
  the active server's transport: a connect failure fires the client
  `disconnect` event, which clears `activeServer`, so transport can't be
  read back there. The memo re-runs as stderr/fetch entries stream in, so
  the diagnostic tab appears as soon as the failing process prints.

Verified live against a failing `python -m mcp_server_time` stdio server:
the column auto-opens to Console showing the real ModuleNotFoundError.

React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

React Compiler

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:

export default defineConfig([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...

      // Remove tseslint.configs.recommended and replace with this
      tseslint.configs.recommendedTypeChecked,
      // Alternatively, use this for stricter rules
      tseslint.configs.strictTypeChecked,
      // Optionally, add this for stylistic rules
      tseslint.configs.stylisticTypeChecked,

      // Other configs...
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])

You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:

// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'

export default defineConfig([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...
      // Enable lint rules for React
      reactX.configs['recommended-typescript'],
      // Enable lint rules for React DOM
      reactDom.configs.recommended,
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])

HTTP proxy support

The web backend connects to remote MCP servers through the shared Node transport (core/mcp/node/transport.ts), which honors the conventional proxy environment variables: HTTPS_PROXY / HTTP_PROXY (and their lowercase forms) select the proxy, and NO_PROXY exempts hosts. Routing is powered by undici's EnvHttpProxyAgent, imported lazily only when a proxy variable is set, so runs without a proxy configured pay no cost. See the CLI README for more detail.
