Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

      "command": "git",

Click the MCP Servers icon in the Cline sidebar, then "Edit Configuration".

Same shape as Claude Desktop. Restart Windsurf to pick up changes.

~/.continue/config.json

  "mcpServers": [

        "~/.claude/skills/SwiftUI-Agent-Skill"
      ]
    }
  ]
}

Continue uses an array of server objects rather than a map.

~/.config/zed/settings.json

{
  "context_servers": {
    "swiftui-agent-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/twostraws/SwiftUI-Agent-Skill",
          "~/.claude/skills/SwiftUI-Agent-Skill"
        ]
      }
    }
  }
}

Add to context_servers. Zed hot-reloads on save.

claude mcp add swiftui-agent-skill -- git clone https://github.com/twostraws/SwiftUI-Agent-Skill ~/.claude/skills/SwiftUI-Agent-Skill

One-liner. Verify with claude mcp list. Remove with claude mcp remove.

Use Cases

Real-world ways to use SwiftUI Agent Skill

Build a settings screen the right way (iOS 17+)

👤 iOS devs ⏱ ~15 min intermediate

When to use: You want a Settings screen that's actually idiomatic for iOS 17+.

Prerequisites

Server/skill installed and authenticated — See repo README

Flow

Plan

Using the SwiftUI skill, design a Settings view with sections: Account, Notifications, About. Use @Observable for the view model.✓ Copied

→ View hierarchy + ViewModel sketch
Code

Write the full file with toggles, NavigationLink to subpages, and a confirmation dialog for sign-out.✓ Copied

→ Compiles on Xcode 15+

Outcome: Idiomatic SwiftUI you don't have to rewrite next year.

Pitfalls

Don't mix @StateObject with @Observable — Don't mix @StateObject with @Observable — the skill enforces one or the other; follow it.

Cost & Limits

What this costs to run

API quota: See provider docs for rate limits
Tokens per call: Varies by tool
Monetary: See repo README for pricing details
Tip: Cache tool results and avoid repeated identical calls.

Security

Permissions, secrets, blast radius

Credential storage: Use environment variables; never commit secrets

Data egress: Tool calls go to the provider's API as documented

Troubleshooting

Common errors and fixes

view doesn't update on state change

Ensure the property is on an @Observable class, not a struct. The skill's checklist covers this.

Verify: @Observable annotation present

preview crashes

@Observable views need a real instance in #Preview. The skill's examples show the pattern.

Verify: Preview compiles
