Since Monday, Knock2 identified 96 people across 51 companies, and 31 of them came from paid campaigns. Here are the ten worth your time, starting with the strongest:
1. Jordan Blackwood, VP of RevOps at Northbeam Labs
- Who: Runs RevOps at a data analytics company in Austin, 51 to 200 employees, on HubSpot and Outreach. Scores 88 and is marked Qualified.
- Came from: LinkedIn ad, Q4 RevOps playbook campaignutm_source=linkedin · utm_medium=paid · utm_campaign=q4-revops-playbook · utm_content=playbook-ad-v2
- Page visits:
- Oct 5, 9:14am: /resources/revops-playbook, about 6 minutes
- Oct 5, 9:21am: /pricing, 3 minutes
- Oct 6, 2:40pm: /pricing again, then /integrations/hubspot
- Oct 7, 8:05am: /customers, read the Baseten story
- CRM: Not in HubSpot yet. Ingrid Solberg (VP of Sales) is the other likely buyer.
- Why it matters: The ad did its job. Jordan read the playbook it promoted, went straight to pricing, came back the next day to check the HubSpot integration, and is now reading customer stories. That is a buyer, not a browser.
- 2. Mateo Ruiz, Director of Sales Ops at Quillbank · Google Ads, competitor-rb2b
- 3. Rachel Moss, Head of Sales at Frostlake · Google search
- 4. Amara Okonkwo, Head of Demand Gen at Hedgerow · Meta ads, q4-retargeting

It doesn’t just answer. It does the work.
Your best rep researches the account, writes a personal note and works the right list.
The MCP gives every rep that ability. Claude reads live visitor data from Knock2, then pushes contacts to your CRM, sequences and Slack when you say so.
Actions are marked as changes, so Claude can check with you before it adds or sends anything.

FAQ
Frequently asked questions
How does Knock2 identify visitors on my site?
You add a small script to your site. When someone visits, Knock2 matches that visit against licensed identity data to resolve the person and the company behind it. You get name, title and business contact details.
Most visitor identification tools work from IP address alone. That resolves a corporate network but not a visitor on home WiFi, mobile or a VPN. That is most B2B traffic today.
What exactly does the Knock2 MCP do?
It connects your live Knock2 visitor data to Claude, Cursor and other AI tools. Instead of opening a dashboard, you ask: "Who from our ICP was on pricing this week?" or "Draft outreach for the Wiz visitor." Claude answers with real data from Knock2.
It can also act. Claude can add a contact to your CRM or a sequence, find the buying committee, or set up a Play, and asks before it does.
What's the difference between account-level and person-level identification?
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.
What is MCP and why does it matter?
MCP (Model Context Protocol) is an open standard that lets AI tools like Claude connect to live data and tools. Without it, Claude only knows what you paste in. With it, Claude can look things up and take actions mid-conversation.
For sales teams, that means your AI works from what is happening on your site right now.
Will this work with my CRM and sales tools?
Yes. Knock2 connects natively to HubSpot, Salesforce, Attio, Slack, Microsoft Teams, Apollo, Outreach, Lemlist, Instantly, HeyReach, Smartlead and Amplemarket. Webhooks cover Clay, Zapier, Make, n8n and anything else that accepts them.
Through the MCP, Claude can push contacts to your CRM, Slack and most of these sequencing tools for you.
Which AI tools does Knock2 MCP work with?
Any MCP-compatible client, including Claude (web and desktop), Claude Code, Cursor and Windsurf. New clients that adopt the standard work too. Setup takes about two minutes in any of them.
Is this actually legal? How does Knock2 identify people without them opting in?
Yes. Knock2 is built on the same class of identity and analytics technology already running on most B2B websites.
Person-level identification runs on US traffic only, by design. Everywhere else, Knock2 returns company-level information only. That is how it stays within GDPR, CCPA and ePrivacy expectations. The identity data itself is licensed from established data providers.
Do I need to already be a Knock2 customer?
Yes. The MCP reads your Knock2 visitor data, so you need a Knock2 account with the tracking script on your site. You can start a free trial and have the script live in minutes.
Does Knock2 work outside the US? What about GDPR?
Person-level identification, with names, emails and contact details, is limited to US traffic by design. Account-level identification works globally. 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.
How is this different from just asking Claude about my pipeline?
Without the MCP, Claude has no idea who is on your site. You would have to export data, paste it in and explain it yourself.
With the MCP, Claude pulls live data from Knock2: who visited, which pages they read, how they score against your ICP and what outreach has already gone out. Claude stops just helping you think and starts doing the work.
How does pricing work?
The MCP is included in every Knock2 plan at no extra cost. Lookups and actions use the same credits as the dashboard. See pricing for current plans and credit costs. Every plan starts with a 7-day free trial.
How long does setup take?
About two minutes. In Claude, add Knock2 as a custom connector using https://api.knock2.ai/mcp/, sign in to Knock2 and approve access. No API key needed.
For Claude Code, Cursor or Windsurf, create an API key in your Knock2 dashboard and paste one command or one block of JSON.
Is my visitor data secure when accessed through the MCP?
Yes. Every request is authenticated, either by your Knock2 sign-in (OAuth) or by your API key, and sent over HTTPS. Only your workspace can see your data. The MCP does not share it with Anthropic, other Claude users or any third party.
You can revoke access or an API key from your dashboard at any time.
Can non-technical team members use this?
Yes. After the two-minute setup, using the MCP is just typing a question into Claude. Reps don't need to know what MCP stands for. They ask "Who should I reach out to today?" and Claude does the rest.
