YNAB's own API docs list it under community-built tools and state they provide no support for them. · Local use needs a long-lived YNAB personal access token. The README also advertises a hosted OAuth connector on a third-party domain (ames-ynab.link) that stores your OAuth tokens in Cloudflare KV. · README includes agent-directed setup text (asking the user about a 1Password token and permission before using it). Benign, but it is text aimed at the AI. Tool descriptions not read. |
