mcp-gads

Google Ads MCP server — query campaigns, keywords, assets & more via natural language.
Built with Bun + TypeScript. Works with Claude, Cursor, and any MCP client.

Quick Start

1. Get Credentials

You need a Google Ads API developer token and OAuth client credentials.

1. Download your OAuth client JSON from Google Cloud Console
2. Set environment variables:

export GOOGLE_ADS_DEVELOPER_TOKEN=your-token
export GOOGLE_ADS_CREDENTIALS_PATH=./credentials.json

3. Run the setup helper to authorize:

npx mcp-gads setup

This opens your browser, completes OAuth, and saves a refresh token.

2. Add to Claude Code

claude mcp add google-ads --scope user --transport stdio \
  -e GOOGLE_ADS_DEVELOPER_TOKEN=your-token \
  -e GOOGLE_ADS_CREDENTIALS_PATH=/path/to/credentials.json \
  -- npx -y mcp-gads@latest

That's it. Restart Claude Code and the tools are available. Every session runs the latest version automatically.

Also works with bunx mcp-gads@latest if you have Bun. Requires Node 22+ when running via npx.

If your environment blocks npm registry access at runtime, install once and run the published binary name directly:

npm i -g mcp-gads@latest
claude mcp add google-ads --scope user --transport stdio \
  -e GOOGLE_ADS_DEVELOPER_TOKEN=your-token \
  -e GOOGLE_ADS_CREDENTIALS_PATH=/path/to/credentials.json \
  -- mcp-gads

curl -Lo mcp-gads https://github.com/pijusz/mcp-gads/releases/latest/download/mcp-gads-darwin-arm64
chmod +x mcp-gads
sudo mv mcp-gads /usr/local/bin/
claude mcp add google-ads --scope user --transport stdio \
  -e GOOGLE_ADS_DEVELOPER_TOKEN=your-token \
  -e GOOGLE_ADS_CREDENTIALS_PATH=/path/to/credentials.json \
  -- /usr/local/bin/mcp-gads

Invoke-WebRequest -Uri "https://github.com/pijusz/mcp-gads/releases/latest/download/mcp-gads-windows-x64.exe" -OutFile "$env:LOCALAPPDATA\mcp-gads.exe"
claude mcp add google-ads --scope user --transport stdio -e GOOGLE_ADS_DEVELOPER_TOKEN=your-token -e GOOGLE_ADS_CREDENTIALS_PATH=C:\path\to\credentials.json -- "%LOCALAPPDATA%\mcp-gads.exe"

ChatGPT Codex

Codex uses TOML, not JSON. Install once, then add to ~/.codex/config.toml:

npm i -g mcp-gads

[mcp_servers.gads]
command = "mcp-gads"

[mcp_servers.gads.env]
GOOGLE_ADS_DEVELOPER_TOKEN = "your-token"
GOOGLE_ADS_CREDENTIALS_PATH = "/absolute/path/to/credentials.json"

Three gotchas that cause silent failures on Codex:

• Don't use npx -y without raising the timeout. Codex's default startup_timeout_sec is 10s, which is too short for npx's first-run download. A global install (above) or the prebuilt binary sidesteps this entirely. If you must use npx, add startup_timeout_sec = 30.
• Env vars must go under [mcp_servers.gads.env]. Codex does not inherit the parent shell environment into stdio servers — exporting vars in your shell won't reach the server.
• Use absolute paths for GOOGLE_ADS_CREDENTIALS_PATH. Codex spawns the server with its own cwd, so relative paths silently miss.

On Windows some Codex versions use startup_timeout_ms = 20000 instead of _sec.

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "google-ads": {
      "command": "npx",
      "args": ["-y", "mcp-gads@latest"],
      "env": {
        "GOOGLE_ADS_DEVELOPER_TOKEN": "your-token",
        "GOOGLE_ADS_CREDENTIALS_PATH": "/path/to/credentials.json"
      }
    }
  }
}

{
  "mcpServers": {
    "google-ads": {
      "command": "/usr/local/bin/mcp-gads",
      "env": {
        "GOOGLE_ADS_DEVELOPER_TOKEN": "your-token",
        "GOOGLE_ADS_CREDENTIALS_PATH": "/path/to/credentials.json"
      }
    }
  }
}

{

Configuration

Updates

Using npx @latest (recommended): You always get the latest version — no manual updates needed.

Using a binary: The server checks for new releases on startup and logs to stderr if outdated:

[mcp-gads] v0.2.0 available (current: v0.1.0). Download: https://github.com/pijusz/mcp-gads/releases/latest

Check your installed version:

mcp-gads --version

To update, download the new binary and replace the old one.

Development

Requires Bun.

git clone https://github.com/pijusz/mcp-gads.git
cd mcp-gads
bun install
bun test           # tests
bun run build      # standalone binary
bun run inspect    # MCP Inspector
bun run check      # biome format + lint
