The `browser_use` capability gives an agent a `browser` tool on a Browserless browser. Pages are read as an accessibility tree with element refs, and the agent acts by ref or viewport coordinate, fills forms, finds text and works across tabs. Traffic goes through the Everruns network guard.

On Claude models that support Anthropic’s native browser toolset, the capability uses it directly; set `native_tools: false` to keep the function tool.

Browser use is experimental and ships behind the `browserless_browser_use` feature flag.
