For AI agents

Install whoisbrowsing from your coding agent

whoisbrowsing is built so a coding agent (Claude Code, Cursor, Codex and others) can add it to a project with no one signing up first. The agent creates a site, puts one script tag in the right file, and hands you two links: one to watch your visitors live, and one to keep the site under your Google sign-in.

Everything for agents

• SKILL.mdOne Markdown file with everything an agent needs, from creating the site to verifying it. Also an Agent Skill.
• MCP serverRemote, streamable HTTP, no auth: create_site, get_install_instructions and check_live.
• Agent API + OpenAPIPOST /api/agent/sites creates a site with no sign-up. The spec is OpenAPI 3.1.
• llms.txtAn index of every page and guide as Markdown links, plus llms-full.txt with all of them.
• Markdown twinsAdd .md to any article, install guide or main page for its Markdown source, like this page's.

MCP server

A remote MCP server over streamable HTTP, with no auth, listed in the official MCP Registry as com.whoisbrowsing/mcp. Add it to your agent once, and it can create the site, read the install guide for your framework and check that the script is connected.

• create_site({domains, name?}): creates a site with no sign-up; the same answer as the API: snippet, watch links, claim link.
• get_install_instructions({platform}): where the tag goes on one platform (the install guide's Markdown), or the list of platforms.
• check_live({siteId, key}): whether the script is connected right now: websites, visitors and whether the owner is watching. key is the owner key after #wib= in the watch link.

Agent API

POST https://whoisbrowsing.com/api/agent/sites creates a site with no sign-up and no auth.

curl -sS -X POST https://whoisbrowsing.com/api/agent/sites \
  -H 'Content-Type: application/json' \
  -d '{"domains":["localhost:3000","example.com"]}'

Errors are JSON with a hint: 400 for a bad body, 429 past the limits (10 sites per network per hour, 5 unclaimed sites per browser). The spec: openapi.json (OpenAPI 3.1). The full walkthrough is SKILL.md.

The two links are for you, not the code

The watch link opens your own site with the live view on. It holds a private owner key, so treat it like a password. The claim link keeps the site in your account once you sign in with Google; it works once and expires after 30 days. A good agent hands you both in its reply and never writes them into the repository. Only the tag goes in the code.

llms.txt and Markdown twins

• llms.txt: an index of every page and guide, as Markdown links.
• llms-full.txt: every guide in one file.
• Markdown twins: add .md to any article, install guide or main page for its Markdown source, for example /install/nextjs.md or /for-agents.md.

Privacy, word for word

• Your visitors' browsers send the page, pointer position, clicks, scroll, device type, source, browser and operating system, and time on site. Never keystrokes, form values or page text.
• Nothing about your visitors is stored on our servers.
• No cookies on your visitors.
• Visitors from the EU/EEA, UK and Switzerland, and browsers with Global Privacy Control, are never shown.
