Currently the server requires the offine token in the OFFLINE_TOKEN environment variable, or in a request header. But use of offline tokens is deprected, and will be removed in the future. To avoid using them this patch adds an optional mechanism to use the OAuth authorization code flow, intended for use when the server is executed locally by the user. When the server starts it checks if the USE_AUTHORIZATION_CODE_FLOW environment variable is set to true. If it is then the authorization URL will be opened with the local browser, so that the user can provide the credentials. Then the authorization server will send the authorization code to the /oauth/callback endpoint, and the MCP sever will exchange that code for the refresh and access tokens. The refresh token is then used as it was the offline token.
