iOS installation

Add this repository as a Swift package with version 0.1.0, then select the MCPMobile library product. Or add it to Package.swift:

.package(url: "https://github.com/tavric-labs/mcp-mobile.git", from: "0.1.0")
// Target dependency:
.product(name: "MCPMobile", package: "mcp-mobile")

Requirements: iOS 16+, macOS 13+, Swift 6.1.

First client

import MCPMobile

let client = try MCPMobileClient(endpoint: serverURL, accessTokenProvider: {
    credentials.currentAccessToken()
})
try await client.connect()
let page = try await client.listTools()
await client.close()

Interactive sign-in

For interactive sign-in, supply the official OAuthAuthorizer with BrowserAuthorizationPresenter as its authorization delegate, and optionally KeychainTokenStorage. The host provides its callback scheme, presentation window and OAuth scope policy. Register the callback URL scheme in the app's Info.plist.

• BrowserAuthorizationPresenter implements the upstream OAuth authorization delegate with AuthenticationServices.
• KeychainTokenStorage implements the upstream token storage protocol with device-only, when-unlocked Keychain items.
• No client secret belongs in a public mobile app.

See Cully's apps/ios/Sources/CullyModel.swift for a consuming application.

Verification status

The package compiles and has passed authenticated Cully read checks on macOS. Physical iPhone verification is separate; see verification.
