Reddit MCP Buddy

Rate limit errors: Add Reddit credentials for higher limits

Reddit API enforces dynamic rate limits based on HTTP response headers. Unauthenticated requests have lower limits. Add Reddit OAuth credentials (client_id, client_secret, username, password) to environment variables in your MCP configuration for enhanced rate limits. Monitor rate limit headers in responses. Implement exponential backoff on 429 errors. Each OAuth authorization has its own rate limit window.

Subreddit not found: Check spelling (case-insensitive)

Verify subreddit name spelling (case-insensitive). Check if subreddit exists by visiting r/subredditname in browser. Ensure subreddit is public (private subreddits require authentication). Some subreddits may be banned or quarantined. Use Reddit search to confirm subreddit name before querying.

Private subreddits require authentication

Private subreddits require Reddit OAuth authentication. Add Reddit credentials (client_id, client_secret, username, password) to your MCP configuration environment variables. Ensure your Reddit account has access to the private subreddit. Create a Reddit OAuth app at https://www.reddit.com/prefs/apps if you don't have one. Use script-type OAuth app for read-only access.

Restart Claude Desktop after config changes

Claude Desktop requires a restart to load new MCP server configurations. After adding or modifying the reddit-mcp-buddy configuration in claude_desktop_config.json, fully quit and restart Claude Desktop. Verify the server is loaded with claude mcp list command (Claude Code) or by asking Claude to list available tools. Configuration changes take effect only after restart.

Reddit MCP server authentication errors with OAuth tokens

Verify OAuth token is valid and not expired. Check token scopes match required operations. Ensure token format is correct (Bearer token in Authorization header). For OAuth integrations, verify token refresh logic is working correctly.

Reddit rate limit errors when making multiple API calls

Implement exponential backoff retry logic with jitter. Use Reddit API rate limit headers to monitor usage. Reduce concurrent requests. Cache frequently accessed content data. Reddit allows 60 requests per minute per OAuth application.

Reddit post or subreddit access denied errors

Verify OAuth token has access to the post or subreddit. Check subreddit permissions and user role. Ensure OAuth token has required scopes (read, submit, modposts) for target operations.

Reddit MCP server connection timeouts or network errors

Check network connectivity and firewall settings. Verify Reddit API endpoints are accessible. Increase request timeout values. Implement connection pooling and retry mechanisms with exponential backoff.
