Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Swift reviews, local Apple references, app scaffolding and iOS simulator workflows.
These three are never merged into one score: opinions, measurements and popularity are different things.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Give your coding agent the Apple references, Swift source and local tools it needs to build and review an iOS app.

Describe an app in one sentence and the /ios-build agent plans it, writes the SwiftUI code and Xcode project, then builds and runs it in the simulator (what has been verified, example apps on the website). For an existing project, the same package gives your coding agent reviews, local Apple references and simulator tools to check its work.

/ios-build " " asks Claude Code to plan an iOS app, write its SwiftUI code and Xcode project, apply capability modules (sign-in, storage, payments, maps and more), then build, run and screenshot it in the iOS Simulator, ending with a report of what needs your accounts or money. Published tools are in ios-agent-mcp 2.10.2 (npm verified October 15, 2026), including plan-driven design tokens, sample data, palette-aligned assets, light/dark/XXL screenshot evidence, deployment-target checks and App Store readiness reports. Four existing apps built and ran on Xcode 27.0; see examples/agent for refreshed evidence.
Install the published server and Claude Code command:
claude mcp add ios-agent -- npx -y ios-agent-mcp@latest
npx -y ios-agent-mcp@latest install-command --global
Then, in any Claude Code session on a Mac with Xcode 16 or later:
/ios-build "A habit tracker with a list, a detail screen, and settings with dark mode toggle"
Shipping (unreleased GitHub source): ios-agent-mcp ship prepares screenshot sets and metadata, then offers separately approved signing/archive and TestFlight upload steps. Setup and limitations. Live signed distribution is not yet verified; npm is unchanged.
Windows/Linux or cloud client: the GitHub source now includes build --remote for unsigned builds and simulator screenshots on GitHub Actions. It requires a destination repository, GitHub CLI authentication and pinned toolkit/Xcode versions. See remote macOS setup and billing. npm publication is deferred.
XcodeGen is optional: without it, the agent writes a folder-synchronized Xcode project itself. The steps are described in docs/tooling/ios-build-agent.md. The four screenshot examples reused existing app folders; this exact one-sentence quickstart has not yet been run from planning through code generation in one Mac session.

Plans, generated sources, run reports and what was and was not exercised: examples/agent.
Every capability is a folder in capabilities/ with a manifest, recipe, Swift template, apply hook and verify hook. The catalog lists the wider landscape for planning and cost estimates. The counts below are generated from the manifests.
| Status | Capabilities |
|---|---|
| Verified on a Mac | 7 |
| Module exists, not yet verified on a Mac | 41 |

162 catalog entries in 31 categories; generated from capabilities/CATALOG.md.
The agent builds and runs everything in the simulator without accounts. Capabilities that need a service declare the keys in their manifest. Client keys, such as a publishable key, go in the project's gitignored .env file and reach the app through a generated xcconfig. Until they are set, the keys are REPLACE_ME placeholders, so the app still builds and shows a configuration message. Server secrets are never put in the app. PLAN.md lists what each run needs and the cost model of each service. Running on a device, using TestFlight or publishing needs your Apple Developer Program membership.
| You want to | Use | Notes |
|---|---|---|
| Build a new app from a description | /ios-build " " in Claude Code, or ios-agent-mcp build | Plans, writes, builds, runs and screenshots; see above. Available in npm 2.10.2 and GitHub main. |
| Make an existing project pass your own acceptance tests | ios-agent-mcp loop | Runs the checks you write and asks Claude to repair failures; see the app-building loop and the Reading List demo. |
| Get an editable starter only | ios-agent-mcp new MyApp | A starting point with a brief, not a finished app. |
| Review or extend code you already have | The MCP tools below | File-located reviews, local references, assets and simulator checks. |
For Claude Code:
claude mcp add ios-agent -- npx -y ios-agent-mcp@latest
Set up ChatGPT/Codex, Gemini CLI or Muse. One npm package includes reviews, local references, app scaffolding and simulator tools. Node.js 20+ is required; local iOS builds need macOS and Xcode; the GitHub-source remote lane runs those steps on Actions.
Then ask:
Build a SwiftUI reading list with local persistence, search and accessible empty/error states. Reuse the local source library. Build it, run the tests and capture simulator evidence. Explain any checks that fail.
For an existing app, provide its absolute project path and ask for a focused review before making changes.
| Feature | What you get |
|---|---|
| Build an app from a sentence | The ios-build agent plans screens, data and capabilities, writes SwiftUI and the Xcode project, then builds, runs and screenshots the app in the simulator. Available in ios-agent-mcp 2.10.0. |
| Start an app | An editable Swift starter, implementation brief and optional XcodeGen specification. |
| Reuse Apple knowledge | Search local Swift source and guides in bounded sections, plus a dated directory of Apple technologies and release notes. |

| Generate design assets | Named light/dark/high-contrast colors and an opaque 1024px app icon rendered locally from editable SVG layers. |
| Review app color systems | Generate semantic palettes and inspect light, dark and high-contrast color evidence. |
| Review backend integration | Identify supported services and review credential, auth, policy and networking evidence locally. |

| Review launch screens | Conservative target-aware checks for launch configuration, storyboards and asset references. |
| Prepare a local release draft | Inspect selected-target facts, unresolved questions and hashed, resumable local packages without connecting to Apple. |
| App Store Screenshot Studio (GitHub source) | Turn captures into localized screenshot sets with reusable layouts, neutral frames, a preview gallery and validated PNG exports. |
| Apple system integrations (GitHub source) | Preview and review Calendar, Reminders, Contacts, Photos, Camera, Maps, Files, Sharing, Shortcuts and Notifications with permission and capability evidence. |

Create a starter directly:
npx -y ios-agent-mcp@latest new MyApp --brief "A reading list with local storage" --xcodegen
The starter is not a finished app: --xcodegen writes a project.yml that XcodeGen turns into a project. For a complete app from a description, use /ios-build. Generated app ownership and branding belong to the user.
The Reading List demo has persistence, search, simulator acceptance tests and captured screens. The four apps the /ios-build agent planned and wrote, with their plans, run reports and simulator screenshots, are in examples/agent.
The published npm 2.10.2 package includes the build-agent tools, deployment-target checks and App Store readiness reports. They include seven Apple system integration tools and nine Screenshot Studio tools. Static reviews are heuristics, not compiler diagnostics. The Apple directory is a reference map, not Apple's proprietary framework source or proof of 405 working integrations. Token savings have not been benchmarked. Build-loop verification limits.
Xcode already ships agent expertise and build/test tools. Use those when they meet your needs. This repository adds shared guidance across these four client families, inspectable rev
