a9df501856* feat(servers): flatten mcp.json settings to top-level fields (#1358) Eliminate the nested `settings` block introduced in #1352 so each server entry's Inspector-extension fields live as direct keys alongside `type` / `url`, matching the `.mcp.json` shape Claude Code / Cursor / Cline write: - `headers` becomes a `Record<string, string>` on disk (was nested `settings.headers` as a pair-array) - `oauth` becomes a nested `{ clientId?, clientSecret?, scopes? }` object (was flat `settings.oauthClientId` / `oauthClientSecret` / `oauthScopes`) - `metadata`, `connectionTimeout`, `requestTimeout` move to the entry's top level as-is (Inspector-only fields) The in-memory + wire shape is unchanged from #1352: `InspectorServerSettings` keeps pair-array `headers` and flat `oauth*` fields because the form needs them in that shape to drive controlled-component editing. The bidirectional conversion lives in `serverList.ts` (`storedFieldsToInspectorSettings` / `inspectorSettingsToStoredFields`) and is invoked by `mcpConfigToServerEntries` / `serverEntriesToMcpConfig` and by the server route's `buildStoredEntry`. The `PUT /api/servers/:id` wire envelope keeps the preserve/clear/apply semantics from #1353 — the backend splats validated `settings.*` onto top-level disk keys when assembling the next on-disk shape. Hard-cutover migration per the issue's decision 4: files written by the one pre-#1358 v2/main build have a nested `settings` block; we drop the node on read with a one-line warn including the server id. The persisted headers / metadata / timeouts / OAuth credentials are intentionally lost on first read — users re-enter them via the form (or hand-edit the file into the flat shape). v2 has not shipped a stable release with the nested shape, so the blast radius is dogfooders only. The smuggle-guard in `buildStoredEntry` widens from just `settings` to all six Inspector-extension keys (`settings`, `headers`, `metadata`, `connectionTimeout`, `requestTimeout`, `oauth`), so a caller can't bypass `validateSettings` by nesting any of them inside `config`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address PR review on flatten (#1359) - Single-source the Inspector-extension key list with `satisfies` (finding 1). `INSPECTOR_FIELD_KEY_MAP satisfies Record<keyof StoredInspectorFields, true>` in serverList.ts means a new field on the type forces a compile error here. The set is exported and re-used by the server route's smuggle guard, so adding `proxy` or similar in the future updates all three sites in lockstep. The PUT preserve path now uses a new `stripInspectorFields` helper that derives from the same source instead of hand-destructuring. - Add read-path shape validation in `normalizeMcpServers` (finding 2): `headers: "oops"` / `metadata: 42` / `oauth: []` / non-numeric timeouts are dropped individually with a warn, so a hand-edited malformed file can't put garbage rows into the form. Mirrors the write-side `validateSettings` symmetry. New integration test covers each malformed shape with a partial fixture so a single bad key doesn't take out the whole entry. - Align new warns to the `fileLogger || console.warn` fallback pattern (finding 3) via a small `logWarn` helper, so the legacy-drop and smuggle warns are visible in `npm run dev` where the logger is often unconfigured. - Spec doc tweak: the CLI/TUI out-of-scope note's "writes to `settings.headers`" reference now reads "writes to the entry's top-level `headers` field on disk (post-#1358 flat shape)" (finding 4). Avoids confusion for future readers. - Nits: replace `current.mcpServers[originalId]!` with explicit narrowing; add a comment on the OAuth truthiness drop in `storedFieldsToInspectorSettings` mirroring the write-side comment. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(servers): address pass-2 review on flatten (#1359) - Tighten `isNonNegNumber` with `Number.isFinite` so `Infinity` and `NaN` are rejected at the read boundary, matching the write-side intent (finding D). Hand-edited `connectionTimeout: Infinity` would have passed the prior check and propagated to the form. - Add a one-line comment in `normalizeMcpServers` noting that the per-entry object is mutated in place via the `delete` calls — safe for today's callers (freshly parsed JSON, no other reference held) but worth flagging for the next reader (finding A). Skipping findings B (move type guards to module scope — single call site) and C (`isOauthObject` lenient on extra keys — reviewer confirmed this is the intended forward-compat behavior, matching `normalizeServerType`'s unknown-key passthrough). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(servers): fix mutation-comment caller branch label (#1359) The previous comment named the GET handler's "seed branch" as a caller of normalizeMcpServers, but that branch returns DEFAULT_SEED_CONFIG directly without normalizing. The actual second caller is the file-present branch (after parseStore). Correcting the label so a future reader looking for the seed branch caller doesn't waste time.
