Inspect capabilities, connected publications, and delivery activity before taking action.
Publishing, with your tools in the loop.
Follow tabbed setup instructions directly on Postii’s API and MCP pages. Copy a request or assistant prompt, then explore full references and connection help in the knowledge base.
Structured actions
Preview content, select publications, and submit approved beehiiv drafts or deliveries through browser tools.
Copy a setup prompt
In the workspace menu, open Settings → API & MCP, then choose Set up assistant or Explore the API. Follow the three-step modal, copy the setup prompt, and check API reachability. Assistant access still requires successful tool discovery and a read-only preview in your assistant.
Good to know
The API uses your signed-in browser session. MCP is currently page-scoped WebMCP; external API keys and a remote MCP endpoint are not available yet.
