OpenClaw MCP config: NZ number, SMS, email

Short answer

Add an agentline entry under mcp.servers in OpenClaw's config with url https://agentline.nz/mcp, transport streamable-http and an Authorization header of Bearer ${AGENTLINE_KEY}, then check it with openclaw mcp doctor agentline --probe. This suits always-on, unattended OpenClaw agents; for a personal setup with OAuth sign-in, follow the OpenClaw guide instead.

Before you start

An Agentline NZ API key from Dashboard → API keys, available to the Gateway as AGENTLINE_KEY. Start free with an email inbox (no card), or take a 7-day trial of Starter or Pro to get a number.
Your 028 number is set up within a few days of signup. Your email inbox works straight away.

Steps

Stop the Gateway. OpenClaw's docs say changes to saved servers need the local Gateway stopped.

Add Agentline NZ to the config. Add this to openclaw.json. If you leave out transport, OpenClaw assumes SSE, so set it.

{
  mcp: {
    servers: {
      agentline: {
        url: "https://agentline.nz/mcp",
        transport: "streamable-http",
        headers: { Authorization: "Bearer ${AGENTLINE_KEY}" },
        requestTimeoutMs: 60000,
      },
    },
  },
}

Check it. Run openclaw mcp doctor agentline --probe. It also warns if a header holds a literal secret instead of a variable.
Start the Gateway. Start the Gateway again and ask your agent: What's my Agentline NZ number?

Good to know

If you also set auth to oauth, OpenClaw ignores static Authorization headers.
OpenClaw's openclaw mcp commands don't read mcporter's config. Configure Agentline NZ in mcp.servers.
requestTimeoutMs of 60000 leaves room for wait_for_code, which waits up to 55 seconds.
