v4.4.0

4.4.0

This is a minor release with a wide set of correctness and soundness fixes. Some fixes intentionally make Zod stricter, so code that depended on previously accepted invalid or ambiguous inputs may need small updates.

Potentially breaking bug fixes

What was reviewed

chore(deps): bump zod from 3.25.76 to 4.4.3 — a Dependabot-generated major-version bump across two files:

• package.json: "zod": "^3.25.76" → "zod": "^4.4.3"
• package-lock.json: resolved entry updated to 4.4.3 with new integrity hash

Correctness / breaking-change analysis

This is a v3→v4 major bump. I traced every Zod import and call site in the repo:

src/mcp.ts:23 is the only consumer (import { z } from "zod"). The APIs used are:

z.string().min(1).describe(…)
z.string().optional().describe(…)
z.array(z.string()).optional().describe(…)
z.number().int().min(0).max(3).optional().describe(…)
z.number().positive().optional().describe(…)
z.number().int().min(1).max(24).optional().describe(…)
z.enum([…]).optional().describe(…)

All of these APIs (z.string, z.number, z.array, z.enum, .min, .max, .int, .positive, .optional, .describe) are present and semantically unchanged in Zod v4. None of the v4 breaking changes (stricter discriminated union typing, preprocess optionality deferral, tuple-hole rejection, catch-handling for absent keys) touch any of these call sites.

@modelcontextprotocol/sdk explicitly declares "zod": "^3.25 || ^4.0" as a non-optional peer dependency — confirmed in package-lock.json:908-916 — so the SDK is designed to accept Zod v4 schema objects passed to server.registerTool().

CI

All checks green at the time of review:

• build (20) — ✅
• build (22) — ✅
• analyze (CodeQL) — ✅
• actionlint — ✅

What's good

Narrow, clean mechanical bump. The deliberate isolation of the Zod dependency to a single file (mcp.ts) made this upgrade straightforward to verify; no scattered usage across the codebase to audit.

No test coverage gap introduced — the existing CI suite exercised the build and static analysis with the new version.
