## About

# mcp-reddit-ads

MCP server for Reddit Ads API v3 -- campaign management, ad creation, performance reporting, and audience targeting via Claude.

## Features

- **18 tools** covering full CRUD for campaigns, ad groups, and ads
- Performance reports with daily breakdowns
- Subreddit, interest, and geographic targeting
- Bulk pause/enable operations
- Safe by default: all new entities created in PAUSED status
- Budget inputs in dollars (auto-converts to Reddit's microcurrency format)

## Installation

```bash
npm install mcp-reddit-ads
```

Or clone the repository:

```bash
git clone https://github.com/mharnett/mcp-reddit-ads.git
cd mcp-reddit-ads
npm install
npm run build
```

## Configuration

**Security:** Never share your `.mcp.json` file or commit it to git -- it may contain API credentials. Add `.mcp.json` to your `.gitignore`.

### 1. Reddit OAuth App

Create a Reddit OAuth app at [reddit.com/prefs/apps](https://www.reddit.com/prefs/apps):

- Select "script" type
- Note the client ID and client secret
- Obtain a refresh token with `adsread adsedit read` scopes

### 2. Environment Variables

Set credentials via environment variables:

| Variable | Description |
|---|---|
| `REDDIT_CLIENT_ID` | OAuth app client ID |
| `REDDIT_CLIENT_SECRET` | OAuth app client secret |
| `REDDIT_REFRESH_TOKEN` | OAuth refresh token with ads scopes |
| `REDDIT_ADS_MCP_WRITE` | Set to `true` to enable mutating tools (create/update/pause/enable). Unset = read-only (default). |

### Read-only by default

As of v1.1.0 the MCP starts in **read-only mode**. The 10 read/report/targeting tools are always exposed, but the 8 mutating tools (create/update campaigns, ad groups, ads, and bulk pause/enable) are hidden from the tool list and refused at call time unless `REDDIT_ADS_MCP_WRITE=true` is set in the server's environment. This guards against a casual chat message accidentally mutating live ad spend. Enable writes deliberately, for the sessions where you actually intend to ship changes.

### 3. Config File

Copy `config.example.json` to `config.json` and fill in defaults:

```json
{
  "reddit_api": {
    "base_url": "https://ads-api.reddit.com/api/v3",
    "auth": {
      "client_id": "",
      "client_secret": "",
      "refresh_token": "",
      "user_agent": "reddit-ad-mcp/1.0"
    }
  },
  "defaults": {
    "account_id": "",
    "business_id": "",
    "report_metrics": ["impressions", "clicks", "spend", "ctr", "cpc", "ecpm"],
    "date_range_days": 7
  }
}
```

Environment variables take precedence over config file values.

## Usage

### Claude Code (.mcp.json)

```json
{
  "mcpServers": {
    "reddit-ads": {
      "command": "node",
      "args": ["/path/to/mcp-reddit-ads/dist/index.js"],
      "env": {
        "REDDIT_CLIENT_ID": "$(security find-generic-password -a reddit-ads-mcp -s REDDIT_CLIENT_ID -w)",
        "REDDIT_CLIENT_SECRET": "$(security find-generic-password -a reddit-ads-mcp -s REDDIT_CLIENT_SECRET -w)",
        "REDDIT_REFRESH_TOKEN": "$(security find-generic-password -a reddit-ads-mcp -s REDDIT_REFRESH_TOKEN -w)"
      }
    }
  }
}
```

## Key Conventions

- **Spend values** are returned from the API in microcurrency (1 dollar = 1,000,000 microcurrency units). Divide by 1,000,000 to get dollar amounts. Budget inputs accept dollars and auto-convert.
- **Dates and times** use ISO 8601 format (`YYYY-MM-DDTHH:MM:SSZ`).
- **New entities default to PAUSED** status. Explicitly set status to `ACTIVE` to go live.
- **Report metrics** default to the set configured in `config.json` but can be overridden per request.

## Architecture

- **Resilience**: Uses [cockatiel](https://github.com/connor4312/cockatiel) for retry policies and circuit breaking on API calls
- **Logging**: Structured logging via [pino](https://github.com/pinojs/pino)
- **Response truncation**: Large API responses are truncated at 200KB to stay within MCP message limits
- **Auth**: OAuth 2.0 refresh token flow with automatic access token renewal
