Release Vitals: Build Size, Memory & Performance Audits (MCP)

TURN YOUR AI CLIENT INTO A UNITY RELEASE ENGINEER.

Ask Claude, Codex, Gemini, or another MCP client to run a Unity release workflow. Release Vitals connects the agent to Unity through a local MCP relay. Unity performs the measurements; the agent returns a compact, evidence-labeled answer.

Ask once. Review the confirmation. Let Unity measure. Then re-run and compare after the change you choose.

EXAMPLE PROMPTS

"Audit my Android build size and save it as the baseline."

"Measure again and explain what changed."

"Run release diagnostics and tell me what blocks shipping."

"Investigate why my Unity build failed."

"Audit memory while I reproduce this scene."

"Capture 30 seconds of Play Mode performance and explain the worst spikes."

CORE WORKFLOWS

BUILD SIZE AUDIT

Build the active target after explicit confirmation and measure it through Unity's BuildReport. See total size, the largest assets and output files confirmed in the build, package risks, and baseline deltas. Android adds deep APK, DEX, ABI, and resource analysis and can analyze an existing APK.

MEMORY AUDIT

Run a deterministic static scan or guide a confirmed capture in Editor Play Mode or from a supported connected player. Findings separate proven evidence from likely candidates and explain impact, trade-offs, and next actions. Guided captures can be saved and compared with a memory baseline.

PERFORMANCE AUDIT

Capture a controlled Editor Play Mode window, identify the worst frame-time and GC windows, summarize available markers, and clearly state when exact method or asset attribution is not proven.

RELEASE DIAGNOSTICS & BUILD FAILURE INVESTIGATION

Check readiness blockers, player and build settings, installed analysis tools, relevant Unity logs, bridge availability, and missing prerequisites before searching or changing project code.

WHY IT IS DIFFERENT

WORKFLOWS, NOT A TOOL BAG

Release Vitals gives the agent a small set of opinionated release workflows instead of hundreds of raw Unity commands.

UNITY MEASURES; THE AI EXPLAINS

The AI does not guess from source code alone. Results come from Unity-owned workflows, BuildReport data, captures, logs, and local artifacts.

YOU STAY IN CONTROL

Release Vitals is read-only by default. It does not delete assets or automatically modify your project. Builds and guided captures require explicit confirmation.

LOCAL-FIRST BY DESIGN

The MCP relay and authenticated Unity bridge run locally. Release Vitals has no cloud service and no product telemetry. Data handling by the selected AI client follows that client's account and privacy policy.

USE IT WITH OR WITHOUT AI

Build-size, memory, performance, and diagnostic workflows are also available in the Unity Editor. AI integration adds natural-language workflow control and compact summaries; it is optional.

WHO IT IS FOR

- Solo developers and small teams preparing Unity releases.

- Mobile teams investigating Android build size and memory.

- Developers already using Claude, Codex, Gemini, or another MCP client.

- Teams that want repeatable local audits and evidence they can review.

REQUIREMENTS

- Unity 6000.3.5f2 or newer.

- Node.js 18 or newer for MCP and AI integration only.

- An MCP-compatible AI client for optional AI workflows.

- Unity must remain open while an AI client uses Release Vitals.

- Android Build Support is required for Android builds, deep APK analysis, and Android device capture.

- The included Package Manifest resolves com.unity.nuget.newtonsoft-json 3.2.2.

CURRENT LIMITATIONS

- Performance capture currently runs in Unity Editor Play Mode.

- Connected-player performance capture is not currently supported.

- iOS build-size analysis is not currently supported.

- Release Vitals surfaces evidence and next actions but does not automatically optimize or delete project content.

- Exact source, method, or asset attribution is reported only when the captured evidence proves it.
