LeadTrapper Connectors for Claude
LeadTrapper has two free connectors for AI assistants such as Claude. A connector lets the assistant use a tool while it answers you, so you can ask in plain words (“make WhatsApp links for these numbers”) and get the result in the chat. Both connectors are free, need no account and no sign-in, and store nothing you send them.
| Connector | Address | Tools |
|---|---|---|
| LeadTrapper WhatsApp Tools | https://useleadtrapper.com/mcp |
Create WhatsApp chat links; Format and clean a WhatsApp number list |
| LeadTrapper Contact Finder | https://useleadtrapper.com/mcp/contacts |
Find contact details on a business website |
How to add them to Claude
- In Claude, open Settings, then Connectors.
- Choose Add, then Add custom connector.
- Type a name, for example
LeadTrapper, and paste the address from the table above. - Choose Continue. Claude detects that no sign-in is needed; keep No sign-in selected and choose Add.
- Choose Connect. Claude lists the tools as read-only tools.
- Start a new chat and ask for what you need. The first time, Claude asks your permission to use the tool.
Any other assistant that supports remote MCP servers (Streamable HTTP) can use the same addresses.
WhatsApp Tools
Create WhatsApp chat links turns up to 1,000 phone numbers into wa.me click-to-chat links, with an optional message that is filled in when the chat opens. It adds the country code, removes a leading 0, and applies WhatsApp’s own rules for Mexico (+52 1) and Argentina (+54 9). It makes links only: it does not check whether a number is on WhatsApp and it sends nothing. Example: “Make WhatsApp links for 050 123 4567 and 055 765 4321, country UAE, message: Hello”.
Format and clean a WhatsApp number list takes up to 1,000 numbers, one per line or as CSV lines, and returns them in international format. It marks each number as already correct, fixed, worth checking, a duplicate or not a phone number, with the reason. Example: “Clean this list for WhatsApp, the numbers are from Saudi Arabia: …”.
Both tools use the same number rules as the free WhatsApp link generator and WhatsApp number formatter pages.
Contact Finder
Find contact details on a business website reads one website: its home page and up to three of its own contact, branch, team or about pages. It returns the email addresses, phone numbers (with a wa.me link), numbers the site links as WhatsApp, addresses and social profile links that the business publishes there. Example: “Find the contact details for example.com”.
It works one website at a time and checks up to 10 websites a day for each user. It follows each website’s robots.txt and does not read search engines, maps, social networks, WhatsApp or review sites. Some websites block automated visitors; the tool then says so. A phone number found this way is not checked for WhatsApp.
Privacy and limits
The connectors run on our website’s servers. They do not store the numbers, messages, website addresses or contacts that pass through them, and they do not read your conversations. We count how many times each tool is used per day, and Contact Finder keeps a counter keyed to your IP address for up to two days to apply its daily limit. The privacy policy has the details.
Need more than the free connectors?
The connectors handle a list or a website at a time. The LeadTrapper app for Windows finds businesses on Google Maps, collects their website contacts in bulk, checks which numbers are on WhatsApp and sends your messages from your own WhatsApp. You can try it free for 14 days.
