FAQ from Steel MCP Server

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.
