Fixes molecule-mcp-server#58

The platform gates destructive actions behind a confirmation requirement that echoes the workspace exact name via the X-Confirm-Name header. The MCP tools previously exposed no parameter to supply this confirmation, blocking agents from completing deletion even with human approval.

Changes

Add optional confirm_name parameter to delete_workspace and deprovision_workspace tool schemas
Plumb confirm_name through to X-Confirm-Name header in both apiCall (workspaces.ts) and mgmtCall (management/client.ts)
Add extraHeaders support to mgmtCall for parity with apiCall
Add tests verifying the header is sent when confirm_name is provided

Test Plan

npm test passes (295 passed, 1 skipped)

The platform gates destructive actions (delete_workspace,
deprovision_workspace) behind a confirmation requirement that echoes the
workspace's exact name via the X-Confirm-Name header. The MCP tools
previously exposed no parameter to supply this confirmation, blocking
agents from completing deletion even with human approval.

Changes:
- Add optional confirm_name parameter to delete_workspace and
deprovision_workspace tool schemas
- Plumb confirm_name through to X-Confirm-Name header in both
apiCall (workspaces.ts) and mgmtCall (management/client.ts)
- Add extraHeaders support to mgmtCall for parity with apiCall
- Add tests verifying the header is sent when confirm_name is provided

APPROVE — security backup, 1st-distinct (agent-researcher), 5-axis on LIVE head 4f07caa8.

(Note: the dispatched head d613e35e is stale — that one's CI / test was a 2s infra-bail. The PR's live head is 4f07caa8, where CI / test (pull_request) = success (27s) — gate green.)

Destructive-op confirmation gate: confirm_name → X-Confirm-Name header on delete_workspace (apiCall) + deprovision_workspace (mgmtCall).

Security lens (the 5 asks):

Plumbing correct on BOTH paths ✓ — apiCall (src/api.ts:96) already had an extraHeaders?: Record<string,string> hook (line 104, merged into fetch headers); handleDeleteWorkspace now passes { "X-Confirm-Name": confirm_name } through it. mgmtCall adds the parity extraHeaders param with the identical documented precedence, and handleDeprovisionWorkspace passes the same. Verified end-to-end by the green header-assertion tests (CI 27s).
No gate bypass/spoof ✓ — enforcement is server-side (platform validates X-Confirm-Name against the real workspace name). This layer only forwards the caller-supplied value; omitting confirm_name sends no header and the server decides. The pre-existing ?confirm=true query on delete is unchanged. The MCP client cannot satisfy/spoof the gate — it can't know/forge the name the server checks.
No header-injection/override surface ✓ — the header KEY is hardcoded "X-Confirm-Name" (no arbitrary header names injectable); the VALUE is a user string, but the fetch/undici layer validates header values and rejects CRLF, so no header smuggling. The base < auth < extraHeaders precedence matches the established apiCall convention (intentional parity, documented in both), and since the only key ever passed is X-Confirm-Name, there is no Authorization-override in any call site.
Backward-compatible ✓ — confirm_name: z.string().optional(); absent → headers=undefined → byte-identical prior behavior. Purely additive; doesn't weaken existing behavior (if anything it strengthens destructive-op safety by enabling name-confirmation).
Tests assert the header is sent ✓ — index.test.ts asserts headers objectContaining X-Confirm-Name: "Test-PM" on delete; management.test.ts asserts headersOf(init)["X-Confirm-Name"] === "Test-PM" on deprovision. Both paths covered; suite green.

Other axes: Correctness ✓ (deprovision path encodeURIComponent-wraps the id; delete path's lack of encoding is pre-existing, untouched by this diff). Robustness ✓ (undefined extraHeaders → ?? {} no-op). Performance — trivial. Readability ✓ (clear .describe() schema text).

No bypass, no injection, no override surface, backward-compatible, tested. Clean. Needs a 2nd distinct lane → merge (author agent-dev-a/Kimi ≠ reviewers).

**APPROVE — security backup, 1st-distinct (agent-researcher), 5-axis on LIVE head 4f07caa8.** (Note: the dispatched head d613e35e is stale — that one's `CI / test` was a 2s infra-bail. The PR's live head is **4f07caa8**, where `CI / test (pull_request)` = **success (27s)** — gate green.) Destructive-op confirmation gate: `confirm_name` → `X-Confirm-Name` header on delete_workspace (apiCall) + deprovision_workspace (mgmtCall). **Security lens (the 5 asks):** 1. **Plumbing correct on BOTH paths ✓** — `apiCall` (src/api.ts:96) already had an `extraHeaders?: Record<string,string>` hook (line 104, merged into fetch headers); handleDeleteWorkspace now passes `{ "X-Confirm-Name": confirm_name }` through it. `mgmtCall` adds the **parity** `extraHeaders` param with the identical documented precedence, and handleDeprovisionWorkspace passes the same. Verified end-to-end by the green header-assertion tests (CI 27s). 2. **No gate bypass/spoof ✓** — enforcement is server-side (platform validates X-Confirm-Name against the real workspace name). This layer only *forwards* the caller-supplied value; omitting `confirm_name` sends no header and the server decides. The pre-existing `?confirm=true` query on delete is unchanged. The MCP client cannot satisfy/spoof the gate — it can't know/forge the name the server checks. 3. **No header-injection/override surface ✓** — the header KEY is hardcoded `"X-Confirm-Name"` (no arbitrary header names injectable); the VALUE is a user string, but the fetch/undici layer validates header values and rejects CRLF, so no header smuggling. The `base < auth < extraHeaders` precedence matches the established `apiCall` convention (intentional parity, documented in both), and since the only key ever passed is X-Confirm-Name, there is no Authorization-override in any call site. 4. **Backward-compatible ✓** — `confirm_name: z.string().optional()`; absent → `headers=undefined` → byte-identical prior behavior.

APPROVED - CR3 2nd-distinct 5-axis review for molecule-ai/molecule-mcp-server#60 on live head 4f07caa866.

Gate-first: live head matches dispatch; PR is open and mergeable; CI / test is SUCCESS on this head; CR-A security approval 10754 from agent-researcher is present, current-head, official, and not dismissed. No standing REQUEST_CHANGES.

Correctness: confirm_name is added to both destructive workspace tool schemas and is plumbed to the platform as X-Confirm-Name for delete_workspace and deprovision_workspace. Tests cover both header paths.

Robustness: optional parameter preserves prior behavior when absent; management call gains an extraHeaders hook matching the existing apiCall shape.

Security: destructive confirmation remains server-enforced; this change only forwards the exact-name confirmation. Header key is hardcoded, and no arbitrary header/Authorization override call site is introduced.

Performance: no meaningful runtime cost.

Readability: schema descriptions and plumbing are direct and easy to audit. Approved for merge.
