Use LeadReef in ChatGPT

LeadReef works in ChatGPT as a custom MCP server. Once it is connected, you ask ChatGPT in plain words to find local businesses with no website or a weak one, read their contacts and draft the pitch. It needs ChatGPT on the web: Business, Enterprise and Edu get full access, Pro gets read-only tools. Setup takes about 2 minutes.

What you need

ChatGPT Business, Enterprise or Edu
Full access, including searches. On Business, Enterprise and Edu only a workspace admin or owner can add and publish the server; members then pick it in their chats. Pro can connect custom servers with read-only tools: you can read leads, but not start a search. Set up on the web; the mobile apps cannot add custom servers.
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. ChatGPT does the rest in the same chat: tables, ranking, and drafts of the first email.

@LeadReef find plumbers in Chicago with no website or a weak one and draft a short email to the top lead.
@LeadReef show my leads from the last search that have a phone number, sorted by rating.
@LeadReef for my top 5 dentists in Austin, list what is wrong with each website in one line.
@LeadReef how many credits do I have left?

What a chat looks like

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

Kowalski Plumbing has 187 reviews at 4.9 and no website, so people searching "emergency plumber Avondale" find competitors first. Draft:
Subject: Emergency calls you might be missing Hi Tom, Kowalski Plumbing has 187 reviews at 4.9 on Google, but no website, so late-night searches for a plumber in Avondale go to someone else. I build one-page sites for trades with a tap-to-call button. Can I send you a free draft this week?

If it doesn't work

“Add custom MCP server” is missing
Your workspace admin may have turned custom MCP servers off, or your plan does not include them. Ask the admin, or check that you are on Business, Enterprise or Edu.
ChatGPT reads leads but will not start a search
On Pro, custom servers get read-only tools, so searches are not available. Run the search in LeadReef, then read the results from ChatGPT.
LeadReef does not show up under @
Start a new chat and type @ again. If it is still missing, open chatgpt.com/plugins and check that LeadReef is connected.
Allow keeps looping back to sign-in
Allow third-party cookies for chatgpt.com and leadreef.ai, or try 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 ChatGPT

ChatGPT sees the data LeadReef returns in the chats where you use it, the same as anything else you share in a chat, and OpenAI's policies apply to that chat. LeadReef does not send your account data to OpenAI outside those calls. LeadReef privacy policy
