How does OpenClaw act on my apps?

You connect an integration to the agent's tools handle and select operations. OpenClaw calls those operations as tools while it runs.

Is there anything to install?

No. NoClick runs the OpenClaw harness for you in a hosted sandbox.

Can I run it on a schedule?

Yes. A hosted agent can be started from a schedule, a webhook, or another app event.

Which apps can it use?

Any of NoClick’s tool-provider integrations across communication, CRM, developer tools, databases, and more.

Set up in minutes

The open button drops you into a guided setup. It asks exactly this, nothing else:

Choose where it runs
On your computer through your own OpenClaw, or hosted in the cloud. The rest of setup adapts to your choice:
Pick what it can do in Lettr
A preset of real Lettr operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Lettr
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your OpenClaw first calls in. OpenClaw probes the server while adding it, so this lights up during openclaw mcp add.
Run this in your terminal
$openclaw mcp add noclick --url https://mcp.noclick.app/s/<your-link>
<your-link> is your personal server URL — setup mints it for you.

About OpenClaw

OpenClaw is an open command-line agent. NoClick runs it hosted and lets you connect your apps to it as tools, so it can take real actions across your systems. Wire an integration into the agent and OpenClaw can call that app’s operations directly. It is a good fit when you want an open, no-fuss agent with real tool access and nothing to install.

Open and approachable

Simple to point at a task

Solid general tool use

Hosted, with nothing to install
