OAuth2 Configuration

This API uses OAuth2 for authentication. The MCP server can handle OAuth2 authentication in the following ways:

  1. Using a pre-acquired token: You provide a token you've already obtained
  2. Using client credentials flow: The server automatically acquires a token using your client ID and secret

Environment Variables

petstore_auth

Configuration Variables:

  • OAUTH_CLIENT_ID_PETSTORE_AUTH: Your OAuth client ID
  • OAUTH_CLIENT_SECRET_PETSTORE_AUTH: Your OAuth client secret

Token Caching

The MCP server automatically caches OAuth tokens obtained via client credentials flow. Tokens are cached for their lifetime (as specified by the expires_in parameter in the token response) minus 60 seconds as a safety margin.

When making API requests, the server will:

  1. Check for a cached token that's still valid
  2. Use the cached token if available
  3. Request a new token if no valid cached token exists
