XcodeBuildMCP

What it does

Drives xcodebuild and the simulator from an agent: build, test, launch, and read logs. This is the missing piece for iOS work, where the build loop otherwise means a human clicking through Xcode. Requires macOS and a working toolchain; expect the first run to fail on code signing rather than on anything the agent did.

Install

npx -y xcodebuildmcp

Client configuration

Paste this into your MCP client config (Claude Desktop, Cursor, or any client that reads mcpServers), then restart the client.

{
  "mcpServers": {
    "xcodebuild": {
      "command": "npx",
      "args": [
        "-y",
        "xcodebuildmcp"
      ]
    }
  }
}

When to use it

Reach for this when the task needs ios inside the agent loop. Skip it if a plain shell command or a one-off script is enough — every server you add costs context and adds a failure mode.

Other TypeScript servers

• Filesystem — Gives an agent scoped read, write, and search access to directories you explicitly allow
• Memory — A persistent knowledge graph stored in a local JSON file, exposed through entities, relations, and observations
• Sequential Thinking — Gives the model a scratchpad for structured, revisable reasoning: numbered thoughts that can branch, revise, and conclude
