420da2e415* feat(servers): export server list as mcp.json download (#1346) Adds an Export button to the Servers screen, next to "Add Servers". Clicking it downloads the current server list as a canonical mcp.json file (2-space indent, same shape serializeStore writes), so the user can hand it off, sync it to another machine, or symlink into Claude Desktop / Cursor / Cline. Wiring: - ServerListControls: new Export Button (variant=default), disabled when serverCount === 0 (nothing to download). - ServerListScreen / InspectorView: thread `onExport` / `onServerExport` through. - App.tsx: onServerExport runs serverEntriesToMcpConfig on the in-memory servers list, JSON.stringify with 2-space indent, and triggers a Blob download via a temporary anchor (appended to body for Firefox compatibility, then removed; object URL revoked). Tests: - ServerListControls unit tests cover button-count (toggle hidden vs shown, Export always present), disabled-on-empty, click fires onExport. - ServerListControls.stories grows play functions for both stories — WithServers asserts Export is enabled + click fires the spy in real Chromium, WithoutServers asserts Export is disabled. - Existing screen + view tests / stories updated for the new prop. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address PR #1351 review (extract helpers + exception safety + guard) Substantive items from the review: 1. Serialization format parity (review #1): added `serializeMcpConfig(entries)` to core/mcp/serverList.ts — a browser-safe helper that runs `serverEntriesToMcpConfig` then stringifies with 2-space indent. Single source of truth for export formatting; can't drift from serializeStore's on-disk shape. 2. Exception safety on the anchor cleanup (review #2) + a direct test for the App.tsx download wiring (review #6): extracted `downloadJsonFile(filename, json)` to clients/web/src/lib/ downloadFile.ts. removeChild + revokeObjectURL run in a `finally` so a thrown click() doesn't leak the DOM node or the object URL. Unit-tested under happy-dom with URL.createObjectURL mocked (happy-dom doesn't ship it). 3. Empty-list guard (review #5): App.tsx onServerExport bails when `servers.length === 0`. The button's disabled prop already prevents the UI path, but the handler is now locally correct against any future programmatic caller (storybook, keyboard shortcut, etc.). Acknowledged but not changed: - Tooltip on the disabled Export button (review #3) — Mantine's disabled-button + Tooltip wart wants a span wrapper + custom events config. Optional per the reviewer; deferred. - Repeated exports → `mcp (1).json` browser suffix (review #4) — a deliberate trade-off since `mcp.json` is the conventional name a user would expect to symlink into Claude Desktop / Cursor / etc. Tests: 1647 unit (+6) + 410 integration + 306 storybook = 2363 green.
