Installation

.package(
    url: "https://github.com/adamtheturtle/MCPClientInstall.git",
    from: "0.1.0"
)

Add the MCPClientInstall product to your target.

Usage

import MCPClientInstall

let server = MCPServerSpec(
    name: "my-server",
    command: "/usr/local/bin/my-server",
    arguments: ["--mcp"]
)

let location = MCPDesktopClient.codex.configurationLocation
let directory = location.directory(relativeTo: homeDirectory)
let configURL = directory.appendingPathComponent(location.fileName)

// JSON: Claude Desktop, Claude Code, or Cursor
let root = try MCPClientInstall.existingJSON(at: configURL)
let merged = try addingMCPServer(server, toJSON: root)
let data = try MCPClientInstall.prettyJSONData(from: merged.root)

// TOML: Codex
let existing = try String(contentsOf: configURL, encoding: .utf8)
let updated = try addingMCPServer(server, toCodexTOML: existing)

Writing is deliberately separate from merging, so an application can show a diff or ask for confirmation first:

try MCPClientInstall.writeConfig(
    data,
    to: configURL,
    backupSuffix: server.backupSuffix
)

For a complete prepare, safe replacement, read-back verification, and recoverable backup in one operation:

let result = try MCPClientInstall.installServer(
    server,
    format: location.format,
    at: configURL
)

let restored = try MCPClientInstall.restoreBackup(
    for: server,
    at: configURL,
    displacedSuffix: ".my-server-before-restore"
)

Safety

MCPClientInstall does not silently replace malformed or structurally incompatible configuration. Its file helper refuses symlinks and special files, retains metadata when replacing an existing file, and keeps the previous contents beside the target.

Applications remain responsible for obtaining user consent and filesystem access. The package has no UI and never searches for or modifies configuration on import.

Requirements

• Swift 6.2+
• macOS 14+
• Linux with a Swift 6.2 toolchain
