Use LeadReef in Cursor

LeadReef works in Cursor as a remote MCP server. Once it is added, the Cursor agent can find local businesses with no website or a weak one, read their contacts and draft the pitch, right next to your code. It works with any LeadReef plan. Setup takes about 2 minutes.

What you need

Cursor with the agent
Add the server for yourself in ~/.cursor/mcp.json, or for one project in .cursor/mcp.json in its folder.
Any LeadReef plan
The free plan includes 1 search a day. Searches use the same credits as in the app.

First prompts to try

LeadReef finds the businesses and their contacts. The agent does the rest: files, tables and drafts of the first email.

What a chat looks like

LeadReef cannot send email. The agent writes the draft from the lead's details, and you send it yourself.

Barton Creek Dental has 164 reviews at 4.9 and no site, so new patients cannot check insurance or book online. Draft saved to email-barton-creek.md:
Subject: New patients who cannot find you Hi Dr. Patel, Barton Creek Dental has 164 reviews at 4.9, but no website, so people searching "dentist Zilker" cannot see which insurance you take or book. I build simple sites for dental practices with online booking. Want a free mockup this week?

If it doesn't work

leadreef shows an error in the server list
Check that mcp.json is valid JSON and the URL is exactly https://api.leadreef.ai/mcp, then switch the server off and on.
The browser never opens to sign in
Open the MCP server list in Cursor and start the sign-in from the leadreef entry.
The agent does not use LeadReef
Mention LeadReef in the prompt, and check that the server is switched on in the MCP list.
Allow keeps looping back to sign-in
Try again in your default browser, or in a private window. Make sure you sign in to the same LeadReef account each time.
Searches stop with a limit message
You used the free plan's daily search, ran out of credits, or reached 10 searches a minute. Reading leads still works. The limits are listed in the technical reference.

Questions about Cursor

No. LeadReef only receives the tool calls the agent makes, such as the business type and city of a search. Your code stays between you and Cursor. LeadReef privacy policy
