Identify & convert visitors, directly from Claude.

The Knock2 MCP connects your live website visitor data directly to Claude, Cursor, Windsurf, and other AI tools. Instead of logging into a dashboard, you just ask — "who's on my site right now?" or "draft outreach for the Lattice visitor" — and Claude answers using real-time data pulled from Knock2. No tab switching. No copy-pasting. Just your pipeline, inside your AI.

Knock2 uses device fingerprinting combined with an identity graph built from consented publisher login data. When someone logs into a major publisher site, their identity is tied to their device. When that same device later visits your site, our pixel matches it back to the person. It's the same underlying technology that powers retargeting pixels from Meta, Google, and LinkedIn.

Traditional visitor ID tools rely on IP address lookup, which fails for anyone on home WiFi, mobile, or a VPN, which is most B2B traffic.

MCP (Model Context Protocol) is an open standard that lets AI tools like Claude connect to external data sources in real time. Think of it like a plugin layer for AI — instead of Claude only knowing what's in its training data, it can call live tools and APIs mid-conversation. For sales teams, this means your AI can finally act on what's happening right now, not just what it already knows.

Account-level identification tells you which company a visitor is from. It's useful for account-based marketing, territory routing, and understanding which target accounts are actively researching you. Person-level identification tells you exactly who the individual is: name, title, work email, phone, and LinkedIn profile. Person-level data is only available for US traffic due to privacy regulations in other regions.

Knock2 MCP works with any MCP-compatible client — including Claude Desktop, Claude Code, Cursor, and Windsurf. As the MCP ecosystem grows, any new client that adopts the standard will work automatically. Setup takes under two minutes in any of them.

Yes. Native integrations are built for HubSpot, Salesforce, Slack, Apollo, Outreach, Lemlist, Instantly, and Clay. For anything not on that list, webhooks cover Zapier, Make, n8n, and any other tool that accepts them. Identified visitors can be routed in real time based on lead score, pages visited, firmographics, persona match, UTMs, or any combination.

Yes — the MCP pulls from your Knock2 visitor data, so you'll need an active Knock2 account with the tracking pixel installed on your site. If you're not a customer yet, you can sign up free and have the pixel live in minutes. The MCP API key is generated from your dashboard once you're set up.

Yes. Knock2 uses the same underlying technology as ad retargeting pixels from Meta, Google, and LinkedIn. Our data comes from consented publisher login co-ops, tying identity to an anonymous device fingerprint.

Without the MCP, Claude has no idea who's visiting your site. You'd have to manually export data, copy it in, and describe the context yourself. With the Knock2 MCP, Claude pulls live visitor data in real time — who's on your site, what pages they're on, how they score against your ICP, and what outreach has already been sent. It's the difference between asking Claude to help you think and asking Claude to actually do the work.

Account-level identification works globally. Person-level identification (with names, emails, and contact details) is limited to US traffic by design. This is how Knock2 stays compliant with GDPR, CCPA, and the ePrivacy Directive in Europe. You won't see individual European or Asian visitors' personal details, but you will see which companies are visiting.

Under two minutes. Generate an API key in your Knock2 dashboard, run one terminal command (or paste one JSON block), and you're connected. There's no OAuth flow, no complex configuration, and no engineering help needed. If you can copy and paste, you can set this up.

Plans start at $199/month (Startup) and scale with included credits. Identifying an account costs 1 credit, identifying a person costs 6 credits, and prospecting additional contacts at an account costs 3 credits. Most teams land on Growth ($499) or Scale ($999) once they see their actual traffic volume. Every plan includes a 7-day free trial.

Yes. All requests are authenticated with your personal API key and transmitted over HTTPS. Your data is only accessible to you — the MCP does not expose your visitor data to Anthropic, other Claude users, or any third party. You can revoke your API key from your dashboard at any time.

Absolutely. Once setup is done — which takes two minutes — using the MCP is as simple as typing a question into Claude. Your reps don't need to know what MCP stands for. They just ask "who should I reach out to today?" and Claude handles the rest. Setup can be done by one person on the team and shared across however many reps need it.
