# OpenClaw

Add the Reduck MCP server to OpenClaw over streamable HTTP, keep its local gateway alive, and bring the model provider it ships without.

OpenClaw reaches Reduck over streamable HTTP, and runs it through a local gateway of its own.

## Before you start

You need a Reduck account, and a paired browser if you want scripts to run on your own Chrome.
Both are in the [quick start](https://docs.reduck.ai/#quick-start).

OpenClaw needs **Node 20 or later**, and a model provider of its own, and it ships with none.

```bash
npm i -g openclaw
```

## Add the server

```bash
openclaw mcp add reduck \
  --url https://mcp.reduck.ai \
  --auth oauth \
  --transport streamable-http
```

> [!WARNING]
> `--transport streamable-http` is required. Without it OpenClaw negotiates SSE and fails with
> `SSE error: Non-200 status code (400)`, which reads like an authorization failure and is not.

Then authorize. This opens your browser; approve the request and the CLI picks up the callback.

```bash
openclaw mcp login reduck
```

## Confirm it is connected

```bash
openclaw mcp probe
```

A working connection lists Reduck's tools, about thirty of them.

The OAuth flow signs you in as whichever Reduck account your browser is already using, which is
not always the one you meant. Ask your agent to call `whoami` and read the handle back before you
rely on it.

## Settings worth changing

OpenClaw asks for approval before each tool call, which interrupts a script mid-run. To let Reduck
run unattended:

```bash
openclaw mcp configure reduck --approval auto
```

OpenClaw reaches the server through a local gateway. Install it as a daemon to keep it alive after
the terminal closes:

```bash
openclaw onboard --install-daemon
```

## If it does not appear

- The transport was left out, so the connection failed as SSE. See the warning above. The error
  names a status code, not the flag that caused it.
- Node is older than 20.
- Sign-in never finished. `openclaw mcp login reduck` has to complete in the browser before any
  tool call works.

## Try it

Ask for something on a real site, and let the agent pick the script:

> Use Reduck to get me the weather in Paris for the next two weeks.

Reduck finds a script for the site, runs it, and hands back the result. The
[script catalogue](https://reduck.ai/explore/scripts) lists everything it can already do.
