Prefer the OAuth browser approval. If your setup needs static config, paste the key block instead.

What are the connection details?

Server URLhttps://mcp.unitpost.com/mcp
TransportStreamable HTTP
Auth (recommended)OAuth 2.1 — add the URL, approve in the browser(scopes match API capabilities; tokens refresh automatically)

How do I connect Windsurf?

  1. Connect with OAuth (recommended)

    In Windsurf: Settings → Cascade → MCP Servers → Add Server, or paste this into `~/.codeium/windsurf/mcp_config.json`. Windsurf uses serverUrl (not url) for remote HTTP. No key to copy. Your client opens Unitpost in the browser — pick a workspace, approve the scopes, and you're connected. Tokens refresh automatically.

    JSON
    {
  "mcpServers": {
    "unitpost": {
      "serverUrl": "https://mcp.unitpost.com/mcp"
    }
  }
}

  2. Refresh and verify

    Refresh the MCP server list. Unitpost's tools should appear under unitpost.

  3. Send a test

    Ask Cascade to send a test email from a verified domain, then confirm in Unitpost Activity.

No browser on this machine? For headless setups, CI, SSH, or clients that can only paste a key, use the API-key setup instead.
