Integrations

One MCP API. Any agent you already use.

Mastheads runs an MCP server at https://api.mastheads.app/v1/mcp. Connect ChatGPT, Claude, Cursor or Codex to it and they can read your publications, your articles, and the sources each article was written from. With a key you created for it, they can start an article and publish one.

get_article_sources returns the pages an article was written from, the verdicts the desks recorded against it, and the editor of record. An agent asking it does not have to take the article on trust, and neither do you.
