MCP setup

Connect your assistant to the tools in your Postii workspace.

1
Open your workspace
Sign in to Postii and keep your dashboard open in a browser that supports WebMCP.
2
Give your assistant the prompt
Copy the setup prompt below. Your assistant needs access to the open Postii tab and its browser tools.
3
Verify the connection
Ask your assistant to discover Postii’s tools and run a read-only check before taking action.

Set up with your AI assistant

Paste this prompt into an assistant with browser site-tool support.

Help me use Postii from my agent through its available MCP tools.
The Analytics page is a sample-data frontend preview only; there is no analytics browser tool.
Independent hosting uses Google or Apple OAuth and server-verified Postii sessions after operator configuration. Email sign-in uses a 6-digit code only after the operator configures Resend and a verified sender. Never ask for a sign-in code. New users enter their first and last name and optional company, then choose a Stripe test-mode trial. Connections are in Settings; invitations require an active Team or Max trial or subscription. Explicitly configured hosted previews use isolated demo sessions, not verified live accounts. Checkout and invitations require operator configuration; live billing is not enabled. Email signup creates a password followed by email verification. Never handle card details yourself. Never treat a button click or redirect as proof of successful authentication. Never ask for passwords, provider secrets or session cookies in chat.
Verified options are ChatGPT desktop with site tools enabled for the account/model, or Gemini through the Chrome Model Context Tool Inspector developer extension with WebMCP enabled. Settings opens a modal; Platforms is inside it; sidebar Platforms opens a full workspace catalog page. My platforms is the default tab; All platforms is for browsing and setup. Read the current MCP guide first. Postii currently exposes page-scoped WebMCP tools on its signed-in dashboard, not a remote MCP server. Do not configure the dashboard URL as an MCP endpoint, invent a server URL or token, or assume beehiiv’s separate OAuth MCP is connected.
Check whether your host supports WebMCP and can access my signed-in dashboard. Settings → API & MCP → Set up assistant opens a three-step setup modal with the prompt and a full-guide link; this is not proof of a connected assistant. If your host supports it, discover the registered tools and verify availability with a read-only preview or connection check. If not, explain the missing capability and the supported next step; do not claim setup succeeded. If you cannot read the private guide, ask me to paste its text.
Discover my connected publications rather than assuming a destination. Connect a platform opens the platform modal; API/MCP setup tools are under Workspace menu → Settings → API & MCP (open the navigation menu on mobile). Sidebar Updates are product news, not account or delivery status. Social schedules are currently sandbox-only; beehiiv has separate real delivery tools with Send API eligibility requirements. Keep setup read-only. Before any later draft, publication, schedule, message or connection change, ask for my explicit approval, including exact content, destination/publication, audience and time. Use distinct operation IDs per publication and reuse each ID with identical input on retries; never retry successful or uncertain sends with a new ID.
Social Connect buttons currently report an unavailable connection, not a successful authorization. Do not treat clicking Connect as evidence that an account is connected.
Let me enter any required secrets in Postii’s connection form. Finish with a short ready/not-ready summary and any next step I must take.

What’s available today
