## About

# 🚀 AdMob Model Context Protocol (MCP) Server

A powerful **Model Context Protocol (MCP)** server that exposes Google AdMob management, mediation waterfall operations, advanced revenue analysis, and A/B experiments directly to MCP-compatible AI clients (such as **Claude Code CLI**, **Claude Desktop**, **Cursor**, **Windsurf**, and **Cline**).

Features a local **Rules Engine** and **Safety Layer** ensuring that mutating operations are audited, verified, and run via dry-runs before touching your live AdMob account.

## 🛠️ Prerequisites & Setup

### 1. Enable the Google AdMob API
1. Open the [Google Cloud Console](https://console.cloud.google.com/).
2. Select or create your project.
3. Search for **AdMob API** in the API Library and click **Enable**.

### 2. Download OAuth 2.0 Desktop Credentials
1. Navigate to **APIs & Services** → **Credentials**.
2. Click **Create Credentials** → **OAuth client ID**.
3. Select **Desktop app** as the Application Type.
4. Download the generated client JSON and save it in the root of this repo as `credentials.json`.

### 3. Create Virtual Environment & Install Dependencies
```bash
python3 -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -r requirements.txt
```

> **Python 3.10+ required.** `fastmcp` does not support Python 3.9 or older.

### 4. Configure Environment (`.env`)
```bash
cp .env.example .env
```
Then edit `.env`:
```env
PUBLISHER_ID=pub-XXXXXXXXXXXXXXXX      # Your AdMob Publisher ID (AdMob UI → Account)
CREDENTIALS_PATH=credentials.json       # Path to your OAuth credentials file
TOKEN_PATH=token.json                   # Where to cache the authorized token
AUDIT_LOG_PATH=audit.log               # Log file for mutating operations
SLACK_WEBHOOK_URL=                      # (Optional) Slack alert webhook
```

### 5. Run the One-time Authorization Flow
```bash
python admob_core/auth.py
```
A browser tab will open — authenticate with your Google AdMob account and grant permissions. This writes `token.json` which is cached and auto-refreshed on all subsequent runs.

## 🔒 Safety, Auditing & Rules Engine

All write operations go through a two-stage safety pipeline before touching the live API:

### Stage 1 — Rules Engine (`rules.py`)
| Rule | Severity | Description |
|------|----------|-------------|
| `format_check` | 🔴 BLOCK | Prevents adding a network that doesn't support the group's ad format |
| `child_directed` | 🔴 BLOCK | Blocks bidding networks on COPPA-tagged apps |
| `min_bidding` | 🟡 WARN | Alerts when fewer than 3 bidding partners are configured |
| `admob_network_required` | 🟡 WARN | Warns if AdMob Network is absent from the waterfall |
| `pangle_region` | 🟡 WARN | Warns if Pangle is added outside its strong geos (APAC, US, BR, MX) |

### Stage 2 — Snapshot + Audit Log (`safety.py`)
- **`dry_run=True`** on any write tool previews the change without hitting the API
- Every real mutation captures a **pre-change snapshot** and appends a structured JSON entry to `audit.log`

---

## ⚙️ Configuration (`config.yaml`)

Customize app categories and rule thresholds:

```yaml
app_categories:
  gaming:
    app_ids: ["ca-app-pub-XXXX~YYYY"]   # AdMob app IDs to tag
    child_directed: false
    primary_formats: ["REWARDED_VIDEO", "INTERSTITIAL", "BANNER"]

rules:
  min_bidding_partners: 3
  stale_ecpm_threshold_days: 30
  stale_experiment_days: 14
```

---

## ❌ Troubleshooting

| Error | Fix |
|-------|-----|
| `ValueError: PUBLISHER_ID must be provided` | Check `.env` contains `PUBLISHER_ID=pub-...` and that the server's `cwd` points to the repo root |
| `FileNotFoundError: credentials.json not found` | Place `credentials.json` in the repo root or set `CREDENTIALS_PATH` to its absolute path |
| `403 Forbidden / AdMob API not enabled` | Enable the AdMob API in Google Cloud Console for your project |
| `401 Unauthorized / Token Expired` | Delete `token.json` and re-run `python admob_core/auth.py` |
| `fastmcp not found` / install errors | Ensure you're using Python 3.10+ (`python --version`) |

---

## 📋 Requirements

- Python 3.10+
