Reddit Ads MCP Server

A Model Context Protocol (MCP) server that provides read-only access to the Reddit Ads API v3.

Features

• List ad accounts, campaigns, ad groups, and ads
• Generate performance reports with flexible metrics and breakdowns
• Daily performance trends
• OAuth2 authentication with automatic token refresh
• Configurable defaults for account ID and metrics

Setup

1. Create a Reddit Developer App

1. Go to https://www.reddit.com/prefs/apps
2. Click "create another app..."
3. Fill in:

• name: reddit-ad-mcp (or your preference)
• type: Select "script"
• redirect uri: http://localhost:8080 (won't be used but required)

1. Click "create app"
2. Note your client_id (under the app name) and client_secret

2. Get a Refresh Token

You need to do a one-time OAuth flow to get a refresh token:

# 1. Open this URL in your browser (replace CLIENT_ID):
https://www.reddit.com/api/v1/authorize?client_id=CLIENT_ID&response_type=code&state=random&redirect_uri=http://localhost:8080&duration=permanent&scope=adsread

# 2. Authorize the app - you'll be redirected to localhost with a ?code= parameter

# 3. Exchange the code for tokens (replace CLIENT_ID, CLIENT_SECRET, and CODE):
curl -X POST https://www.reddit.com/api/v1/access_token \
  -u "CLIENT_ID:CLIENT_SECRET" \
  -d "grant_type=authorization_code&code=CODE&redirect_uri=http://localhost:8080"

# 4. Save the refresh_token from the response

3. Configure the MCP Server

Create config.local.json (copy from config.json):

{
  "reddit_api": {
    "base_url": "https://ads-api.reddit.com/api/v3",
    "auth": {
      "client_id": "YOUR_CLIENT_ID",
      "client_secret": "YOUR_CLIENT_SECRET",
      "refresh_token": "YOUR_REFRESH_TOKEN",
      "user_agent": "reddit-ad-mcp/1.0"
    }
  },
  ...
  "defaults": {
    "account_id": "YOUR_AD_ACCOUNT_ID"
  }
}

4. Install Dependencies

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
