Install

The connector URL is https://versusbrief.com/mcp. Every tool is read-only and none of them touches an ad account.

• On the web — nothing to install: sign in with your email and type the prospect’s website.
• Claude — web and desktop: add a custom connector, sign in with your email.
• Claude Code — one command with a key, or sign in from /mcp.
• Cursor — a block in mcp.json; sign in or use a key.
• ChatGPT — developer mode, sign in with your email.

Two ways to authenticate

• Sign in (OAuth). The app opens a Versusbrief page, you enter your email and choose Allow. That creates a free account.
• API key. Create one on the account page and send it as Authorization: Bearer vb_live_….

One email is one account. The first visit creates the account. After that, the same email gets a one-time link; open it in the same browser to connect another app or to get another key.

Try it

Build a pitch for theirbusiness.co.uk in Didsbury, GB.

That runs pitch_report: the prospect against up to three rivals from Google’s map pack, with a 90-day plan and a page you can send. For one competitor in depth:

Run a teardown of competitor.co.uk in Manchester, GB,
for my client yourclient.co.uk.

Then ask for account_status to see credits left, or list_reports for your links.
