periscope

A command-line browser for AI agents on macOS. It runs Safari's engine (WebKit), so websites see a normal Safari, and it keeps sessions open between commands.

periscope navigate https://books.toscrape.com/ --session demo
periscope text --session demo        # the page as markdown
periscope extract --session demo     # the page's records as JSON
periscope click "text:Next" --session demo

Install

brew install oskar-szulc/tap/periscope
periscope install-skill    # adds the agent skill to this project

Without Homebrew: curl -fsSL https://raw.githubusercontent.com/oskar-szulc/periscope/main/install.sh | sh

To build from source instead (Xcode 26): swift build -c release, then copy .build/release/periscope onto your PATH.

For agents
  • Claude Desktop: download periscope-<version>.mcpb from the latest release and open it
  • Claude Code: /plugin marketplace add oskar-szulc/periscope, then /plugin install periscope@periscope
  • Codex, Cursor and others: npx skills add oskar-szulc/periscope
  • MCP clients: listed in the MCP Registry as io.github.oskar-szulc/periscope; the command is periscope mcp, e.g. claude mcp add periscope -- periscope mcp, or in a JSON config: {"mcpServers": {"periscope": {"command": "periscope", "args": ["mcp"]}}}
  • Any agent with a shell: periscope docs prints the full reference

What else you can do

  • Act: click, fill, type, select, scroll, mouse, targeting CSS or what a person sees (text:Next, label:Email)
  • Stay logged in: named sessions persist; login and show let you take over the window
  • Know when you're blocked: CAPTCHA and bot-check pages exit with code 5

Requirements

  • macOS 26 or newer, in a logged-in desktop session with the display on
