An AI agent can call openid_connect_token faster than any human can review: one bad instruction and it creates or modifies resources in Slack by the hundred, each call as confident as the last.

openid_connect_token Rate-limited

openid_connect_token stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
