Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account jrlingyin888 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server that gives a coding agent a curated catalog of modern SwiftUI components to browse, search and fetch as source code.

What you can do: Browse the catalog's categories and component counts, optionally filtered by category, to see what is available before choosing a component for a view or screen.
When to use it: Useful when an AI coding agent is building iOS or SwiftUI interfaces and you want it to pull current, reviewed components instead of guessing at APIs or reaching for deprecated ones.
Requirements: Runs as a local process over stdio, installed from the npm package swiftforge-mcp (for example via npx), so Node.js and npm are needed on the machine. No authentication, environment variables or headers are declared.

Before you install

The server only serves component source and notes; the agent still writes code into your project, so review what it inserts before building. The README's demo build was verified on Xcode 26 and an iOS 26 simulator, so older toolchains may not compile the newest components.

Installation

In SourceWeft

Open Swiftforge in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

SwiftForge MCP

[npm version] [license] [MCP] [SwiftUI]

A curated, current, production-grade SwiftUI component library — served straight to your AI coding agent over MCP.

Think 21st.dev (curated React components for AI agents), but for SwiftUI.

A quick tour of components from the catalog (incl. iOS 26 Liquid Glass), running in the demo app.

The problem

Coding agents (Claude Code, Cursor, Copilot) are great at logic and mediocre at SwiftUI. They:

reach for deprecated APIs (NavigationView, .foregroundColor, ObservableObject everywhere)
have never seen iOS 26 "Liquid Glass" (.glassEffect, GlassEffectContainer, .buttonStyle(.glass)) and guess wrong
produce bland, one-off views instead of polished, reusable components

You end up rewriting their SwiftUI by hand. Every time.

What SwiftForge does

SwiftForge is a tiny MCP server that gives your agent on-demand access to a hand-curated catalog of modern, compile-ready SwiftUI components. When you ask your agent to "add a glass card" or "build an onboarding flow," it pulls the real, current component instead of hallucinating one.

The value isn't the server — it's the curated catalog: every component uses current API only, is dark-mode + Dynamic Type friendly, includes a #Preview, and is reviewed for taste.

Quick start

Claude Code

Cursor / Windsurf (`~/.cursor/mcp.json` or project `.cursor/mcp.json`)

json

{  "mcpServers": {    "swiftforge": {      "command": "npx",      "args": ["-y", "swiftforge-mcp"]    }  }}

{  "mcpServers": {    "swiftforge": {      "command": "npx",      "args": ["-y", "swiftforge-mcp"]    }  }}

Full setup, example prompts, and troubleshooting: docs/USAGE.md.

Run from a local clone (development)

bash

git clone <this repo> && cd swiftforge-mcpnpm install && npm run smoke# then point your agent at: node /absolute/path/to/src/index.js

git clone <this repo> && cd swiftforge-mcpnpm install && npm run smoke# then point your agent at: node /absolute/path/to/src/index.js

Then just talk to your agent:

"Use swiftforge to add a Liquid Glass stat card to this dashboard." "Search swiftforge for a pull-to-refresh list and wire it to my view model."

Demo app — the closed loop, proven

examples/SwiftForgeDemo is a real iOS app that pulls in all 96 catalog components and builds clean — proof that the full loop works (agent → swiftforge → a compiling iOS app):

bash

npm run demo:gen      # (re)generate the demo project from the catalognpm run demo:build    # headless xcodebuild for the iOS simulator# or just open it:open examples/SwiftForgeDemo/SwiftForgeDemo.xcodeproj

npm run demo:gen      # (re)generate the demo project from the catalognpm run demo:build    # headless xcodebuild for the iOS simulator# or just open it:open examples/SwiftForgeDemo/SwiftForgeDemo.xcodeproj

Verified ** BUILD SUCCEEDED ** on Xcode 26 / iOS 26 simulator — including the Liquid Glass components. The app live-renders a couple of components (paywall, OTP) and lists the full catalog.

Tools the agent gets

Tool	What it does
`list_categories`	See the catalog's categories + counts
`list_components`	Browse components (optionally by category)
`search_components`	Free-text search by what you're building
`get_component`	Fetch one component's full, current SwiftUI source + usage + notes

What's inside

96 curated components across 14 categories: Buttons & Controls · Cards & Containers · Navigation & Bars · Lists & Scroll · Lists & Grids · Forms & Inputs · Charts · Effects & Liquid Glass · Feedback & Overlays · Media · Auth & Account · Animations · Layout & Scaffolding · Onboarding & Hero — including dedicated iOS 26 Liquid Glass components with graceful-fallback notes.

Every component is gated through a syntax check (scripts/validate.js, xcrun swiftc -parse) and a senior-review pass that strips deprecated API.
