Claude Code

Run one CLI command (replace the key), then verify with `claude mcp list`.

What are the connection details?

Server URLhttps://mcp.unitpost.com/mcp
TransportStreamable HTTP
Auth headerAuthorization: Bearer pk_live_YOUR_KEY(production key from www.unitpost.com)
Toolsone per API operation (emails_send, campaigns_send, …)

How do I connect Claude Code?

  1. Create a production API key

    Open https://www.unitpost.com → Settings → API keys → create a scoped key. Copy the full pk_live_… value (shown once). In every snippet below, replace pk_live_YOUR_KEY with that value.

    Must be production. Keys from unitpost.dev only work on the dev API. This MCP URL is production (mcp.unitpost.com) — a .dev key returns 401 Invalid API key on tool calls even if the server appears connected.

  2. Run this command

    Paste as one line. Replace pk_live_YOUR_KEY with your key. Keep Bearer inside the quotes. Flags stay before the name/URL.

    Shell
    claude mcp add --transport http --header "Authorization: Bearer pk_live_YOUR_KEY" unitpost https://mcp.unitpost.com/mcp

    Use -s user to install for every project. Grant only the scopes the agent needs (e.g. emails:send for emails_send). Prefer a revocable key dedicated to the agent.

  3. Verify

    Run claude mcp list (or /mcp in a session). unitpost should be connected with its tools listed.

  4. Send a test

    Ask Claude to send an email from a verified domain and confirm it in Unitpost Activity.
