Perplexity Comet tools (8, 2 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • comet_askwrite action

    Send a prompt to Comet/Perplexity and wait for the complete response (blocking). Ideal for tasks requiring real browser interaction (login walls, dynamic content, filling forms) or deep research with agentic browsing.

  • comet_connect

    Connect to Comet browser (auto-starts if needed)

  • comet_mode

    Switch Perplexity search mode. Modes: 'search' (basic), 'research' (deep research), 'labs' (analytics/visualization), 'learn' (educational). Call without mode to see current mode.

  • comet_poll

    Check agent status and progress. Call repeatedly to monitor agentic tasks.

  • comet_screenshot

    Capture a screenshot of current page

  • comet_stop

    Stop the current agent task if it's going off track

  • comet_tabs

    View and manage browser tabs. Shows all open tabs with their purpose, domain, and status. Helps coordinate multi-tab workflows without creating duplicate tabs.

  • comet_uploadwrite action

    Upload a file to a file input on the current page. Use this to attach images, documents, or other files to forms, posts, or upload dialogs. The file must exist on the local filesystem.
