Use Radar Lab in Claude

Radar Lab works inside Claude. Ask a question in plain words and Claude answers from your Radar Lab picks, competitor gaps and sponsor history, with a table of newsletters you can open.

Before you start

• A Radar Lab Pro account.
• Any Claude plan. Free plans can add one custom connector.
• About two minutes.

Your connector address

Connect Claude

1. In Claude, open Settings → Connectors. Click Add at the top right, then Add custom connector.
2. Name it Radar Lab, paste the connector address under MCP server URL, and click Continue.
3. Keep the settings Claude picks for you (Sign in now and Register automatically) and click Add.
4. On the Radar Lab connector page, click Connect. Sign in with your Radar Lab email if asked, check your business, and click Allow access.
5. Optional: under Tool permissions, change Needs approval to Always allow, so Claude doesn’t ask before each lookup. Every tool is read-only.
6. Open a new chat and ask away. To check, ask “Is Radar Lab connected?”

Things to ask

• “Which newsletters should we sponsor? Use Radar Lab.”
• “Where are our competitors sponsoring that we aren’t?”
• “Which brands sponsor newsletters in our market?”
• “What’s new in Radar this week?”
• “Find newsletters in our market with over 10,000 subscribers.”
• “Where does our biggest competitor sponsor newsletters?”

Good to know

• Read-only. Your AI app can read your Radar Lab data. It can’t change anything, see billing, or contact anyone.
• Daily MCP limits: 10 new searches and 15 new brand lookups a day. Repeating one you already ran is free. Limits reset at midnight UTC.
• Check before you buy. Prices, subscriber counts and availability change, so confirm them with the publisher.
• Part of Radar Lab Pro. If your plan ends, the connection stops working until you upgrade again.
• To disconnect: Claude → Settings → Connectors → Radar Lab → Disconnect.
