Accessing the LRA MCP server with a Refresh or Access Token

For temporary experiments or batch jobs, you can access the LRA MCP server with either a refresh token or an access token. You can fetch the tokens from https://kfinance.kensho.com/manual_login/ (opens in a new tab). The access token expires after one hour while the refresh token expires after one week.

Getting started with just an access token is easiest for tasks or experiments that take less than an hour. You can use the script below as a starting point.
