+We use AI tooling constantly and have no problem with you using it too. But somewhere in the loop there has to be a human who actually understands the change. We have a large backlog and limited reviewer time—we're not spending it on code nobody has read. Not disclosing is also just rude to the people on the other end.

+- **Disclose it.** One line in the PR or issue description. That's it.
+- **Own it.** You can explain the change in your own words. When a maintainer asks a question, the answer comes from you, not pasted from a chat window.
+- **No drive-by agents.** PRs, issues, or comments produced by an autonomous agent with no human review get closed on sight. If your agent is auto-filing PRs against our open issues, stop.
+
+Undisclosed AI contributions get closed. Repeat offenders get banned from the `modelcontextprotocol` org.
