reddit-mcp-server

The server correctly loads sensitive credentials (Client ID, Client Secret, Username, Password, OAuth Token) from environment variables, preventing hardcoding. Input validation for tool parameters is implemented using Zod, reducing common injection vulnerabilities. The RedditClient handles OAuth2 token acquisition and refresh, and includes a retry mechanism for 401 errors. Optional OAuth protection for the HTTP endpoint is available, with token generation if none is provided during setup. No 'eval' or obvious malicious patterns were found in the provided code. However, the OAuth token generation during startup if `OAUTH_ENABLED` is true but `OAUTH_TOKEN` is unset, prints the token to console.error, which might be a minor security exposure if not properly managed in a production environment.
