Codemagic MCP Server

A local Python MCP server that exposes the Codemagic CI/CD REST API as Claude-callable tools. Trigger builds, manage apps, download artifacts, and clear caches — all from Claude Code or Claude Desktop without leaving the chat.

Quick Start

The fastest way to get running with Claude Code — no separate install step needed:

# 1. Add the server (uses uvx to run it on-demand)
claude mcp add codemagic -e CODEMAGIC_API_KEY=your-api-key-here -- uvx codemagic-mcp

# 2. Restart Claude Code — tools will appear in /tools

That's it. See Configuration for optional settings like CODEMAGIC_DEFAULT_APP_ID.

Installation

Requirements: Python 3.11+

Option 1 — uvx (recommended, no install needed)

uvx codemagic-mcp

Option 2 — pip

pip install codemagic-mcp

Option 3 — from source

git clone https://github.com/AgiMaulana/CodemagicMcp.git
cd CodemagicMcp
python3 -m venv .venv
.venv/bin/pip install -e .

Configuration

Get your API token from Codemagic User Settings → Integrations → Codemagic API.

You can provide settings as environment variables or via a .env file:

# .env
CODEMAGIC_API_KEY=your-api-key-here

# Optional: set a default app so you don't have to specify it every time
CODEMAGIC_DEFAULT_APP_ID=your-app-id-here

Default App ID

CODEMAGIC_DEFAULT_APP_ID is optional but recommended if you work primarily with one app. When set, the AI will use it automatically whenever a tool requires an app_id and none was specified. If it is not set, the AI will:

1. Call list_apps to discover available apps.

2. Use the app automatically if only one exists.

3. Present the list and ask you to choose if multiple apps are found.

Register with Claude Code

Run the following command to add the server:

claude mcp add codemagic -- codemagic-mcp

Then set your API key in the MCP env config, or export it in your shell before starting Claude Code:

export CODEMAGIC_API_KEY=your-api-key-here

Alternatively, add it manually to ~/.claude.json:

{
  "mcpServers": {
    "codemagic": {
      "command": "codemagic-mcp",
      "env": {
        "CODEMAGIC_API_KEY": "your-api-key-here",
        "CODEMAGIC_DEFAULT_APP_ID": "your-app-id-here"
      }
    }
  }
}

Using uvx (no prior installation needed)

{
  "mcpServers": {
    "codemagic": {
      "command": "uvx",
      "args": ["codemagic-mcp"],
      "env": {
        "CODEMAGIC_API_KEY": "your-api-key-here",
        "CODEMAGIC_DEFAULT_APP_ID": "your-app-id-here"
      }
    }
  }
}

Restart Claude Code — the tools will appear in /tools.

Register with Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "codemagic": {
      "command": "codemagic-mcp",
      "env": {
        "CODEMAGIC_API_KEY": "your-api-key-here",
        "CODEMAGIC_DEFAULT_APP_ID": "your-app-id-here"
      }
    }
  }
}

Restart Claude Desktop to pick up the changes.

Adding New Tools

1. Add a method to client.py

2. Add the tool function to the relevant tools/*.py file

3. That's it — server.py never needs to change
