Browser

Browser — MCP tools exposed to agents.

3 tools in this group.

browser_quit

Quit the browser entirely: close EVERY session on this server (not just the current one — including isolated sessions and sessions other agents created) and shut down the browser process. The server itself keeps running; the next browser tool call launches a fresh browser. Idempotent — safe to call when nothing is running. To end only the current session, use browser_stop.

No parameters.
