MCP server
Company and contact enrichment for AI agents
Look up companies by IP address or domain, and people by work email, from any MCP client.
Tools
All four are read-only. They never change data in your LeadBoxer account, and every result reports the credits used and the credits left.
lookup_ip
The company behind an IP address, with its domain, ISP, connection type and location. 20 credits.
lookup_domain
Firmographics for a domain: industry, employee range, headquarters, LinkedIn and specialties. 10 credits.
lookup_email
The professional profile behind a work email. 50 credits per profile found, free if none is found.
get_credit_balance
Your remaining credits and when they expire. Free.
Lookups use credits from your own LeadBoxer account, the same credits as the API and the App. Account summaries and recent leads are coming to this server.
Example prompts
“Who is behind IP 193.8.9.0?”
“Enrich acme.com with company details.”
“Who is jane.doe@acme.com? Add her company details too.”
“Here’s my server access log. Identify the companies visiting my API and rank them by employee count.”
“How many LeadBoxer credits do I have left?”

Find us in
The official MCP Registry (com.leadboxer.mcp/leadboxer), Smithery, Glama and mcp.so.
Authentication and privacy
Your client signs in with OAuth through the LeadBoxer Connect page. Scripts, CI and clients without OAuth can send the key as an x-api-key header instead; never put it in a URL. The server only receives the IP, domain or email you ask about, never your conversations.

New accounts start with 25,000 free credits. No card required.
