Frequently asked questions

What prerequisites are needed?

Latest Git and Node.js, Claude Desktop, and (optionally) a running Steel Docker image for self-hosting or a Steel API key for cloud mode.

How do I switch between local and cloud modes?

Set the `STEEL_LOCAL` environment variable to `"true"` for local mode (no API key needed) or `"false"` for cloud mode (requires `STEEL_API_KEY`). Optionally change `STEEL_BASE_URL` for custom endpoints.

What tools does Steel MCP Server provide?

It provides `navigate`, `search`, `click`, `type`, `scroll_down`, `scroll_up`, `go_back`, `wait`, and `save_unmarked_screenshot`.

Where are screenshots stored?

Screenshots are stored as MCP resources accessible via URIs in the form `screenshot://RESOURCE_NAME`.

Is the `GLOBAL_WAIT_SECONDS` env variable required?

No, it is optional. It adds a delay (in seconds) after every tool action to help with slow-loading or dynamic pages.
