What Reddit credentials do I need to set up this MCP server?

You need a Reddit OAuth app's client ID and secret, plus a refresh token. Register your app at reddit.com/prefs/apps, then generate credentials through Reddit's OAuth flow to obtain the refresh token.

Can I manage multiple Reddit ad accounts with one server instance?

The server uses a single set of credentials (REDDIT_CLIENT_ID, REDDIT_CLIENT_SECRET, REDDIT_REFRESH_TOKEN), so each instance manages one Reddit account. Run multiple instances with different credentials to manage multiple accounts.

What ad management operations does this server support?

The server supports creating and managing campaigns, ad groups, individual ads, and audience targeting rules. It also provides reporting and performance metrics for your Reddit ads.

How do I authenticate if my refresh token expires?

Refresh tokens can expire or be revoked. Regenerate a new refresh token through Reddit's OAuth authorization flow and update the REDDIT_REFRESH_TOKEN environment variable.

Is there pricing or rate limiting I should know about?

This MCP server is a client library for Reddit's Ads API; pricing depends on your Reddit ad spend and API rate limits are set by Reddit. Check Reddit's Ads API documentation for current rate limits and quotas.
