AI assistant integrationLeadMarina + Claude
Ask Claude for leads. Get fully verified local businesses back.
LeadMarina's MCP connector turns Claude into a lead generation workspace. Add one custom connector on claude.ai and ask in plain English — "find roofing companies in Phoenix, Tucson, and Flagstaff" — and LeadMarina searches public business listings data by niche and city, one search_leads call per city, which Claude makes for you. Every lead is verified before the search completes: emails SMTP-checked and labeled safe, risky, or invalid; phones checked for line type and carrier; owner names where identifiable; plus socials, ratings, reviews, and the full business profile.
Then finish the job without leaving the chat. Filter and rank delivered leads at zero credit cost, render shortlists as artifacts, keep your qualification rules in a Claude Project, and export to Close, GoHighLevel, Google Sheets, or a CSV file — CRM records update in place instead of duplicating. It works on every Claude plan, on web, desktop, mobile, and Claude Code — whether you're an agency building phone-verified lead lists for clients or a local sales team filling your own pipeline.
Prospect in plain English
Ask Claude for "med spas in Miami, Orlando, and Tampa" and the search_leads tool finds local businesses from public business listings data — one city per call, so Claude makes a call for each.
Every lead arrives verified
Up to 3 emails SMTP-checked and labeled safe, risky, or invalid; up to 3 phones with line type (mobile, landline, VoIP, toll-free) and carrier; owner names where identifiable; plus Facebook, Instagram, LinkedIn, X, YouTube, TikTok, and Yelp profiles, ratings, and reviews.
One connector, the whole workflow
Its tools include search_leads, get_search_results, enrich_domains, query_leads, export_leads, list_searches, get_balance, list_views, list_integrations, and four automation tools (list_automations, create_automation, update_automation, delete_automation) — a complete prospecting workflow over streamable HTTP with OAuth 2.1 or API-key auth. Already have target websites? enrich_domains verifies up to 10 domains per call (1 lead per domain) and returns a search_id to poll with get_search_results.
Qualify without spending credits
query_leads is free, so Claude can filter, sort, and re-slice delivered leads all day. The meter only counts delivery: 1 lead = 1 fully verified business. Ask for a shortlist as an artifact and iterate in the side panel.
Exports that never duplicate
Push leads to Close, GoHighLevel, Google Sheets, or a CSV/Excel/JSON file — a whole search, or just the shortlist query_leads found. Close and GoHighLevel exports update in place, matched on a stable Google business identifier, and so do exports into a spreadsheet LeadMarina created earlier — no duplicates, and your notes, activities, custom fields, and formatting are never touched.
Runs everywhere Claude does
Add it once at Customize > Connectors on claude.ai and use it on web, desktop, and mobile — or `claude mcp add` in Claude Code. Custom connectors work on every Claude plan, LeadMarina's free plan includes 100 leads, and any search can repeat daily, weekly, monthly, or yearly.
- 01
Add the connector
In Claude, open Customize > Connectors, click +, choose Add custom connector, and paste https://leadmarina.com/api/mcp. Sign in when prompted — OAuth 2.1 with dynamic client registration means no client ID or secret to configure.
- 02
Ask for leads
Enable LeadMarina from the + button in chat and ask: "Find HVAC companies in Dallas, Fort Worth, and Plano." Claude runs the search and pulls fully verified results into the conversation.
- 03
Qualify in the chat
Keep your ICP in a Claude Project, then ask Claude to keep only leads with a safe email and a mobile number. Filtering with query_leads is free, and shortlists render as artifacts beside the chat.
- 04
Export and automate
Say "send these to Close" or "keep a Google Sheet updated weekly." Exports to Close, GoHighLevel or a LeadMarina-made spreadsheet update in place — never duplicate — and any search can repeat daily, weekly, monthly, or yearly with any destination. For Close, run one manual Export → Close in the web app first to save the field mapping.

Which Claude plans can use the LeadMarina connector?+
All of them. Custom connectors work on Claude Free, Pro, Max, Team, and Enterprise; Free accounts are limited to one custom connector. On Team and Enterprise, an Owner adds LeadMarina under Organization settings > Connectors, then each member connects their own LeadMarina account.
Does it work in Claude Code?+
Yes. Run `claude mcp add --transport http leadmarina https://leadmarina.com/api/mcp`, then `/mcp` to complete the OAuth sign-in. For headless use, pass a LeadMarina API key with `--header "Authorization: Bearer <key>"` — API keys come with every LeadMarina plan, including free.
Do I need an OAuth client ID and secret in Advanced settings?+
No. LeadMarina supports OAuth 2.1 with dynamic client registration, so leave Advanced settings blank — Claude registers itself and you just sign in.
Will exporting from Claude create duplicates in my CRM?+
No. Exports to Close and GoHighLevel are update-in-place, matched on a stable Google business identifier. Re-running a search updates existing records; your notes, activities, custom field values, extra rows, and formatting are never touched, and GoHighLevel tags are additive-only.
Does chatting about my leads burn credits?+
No. query_leads is free — filter, sort, and re-query delivered leads as much as you like. The meter only counts delivered leads: 1 lead = 1 fully verified business. LeadMarina's free plan includes 100 leads; paid plans include 15,000, 65,000 or 240,000 leads per month, and Unlimited has no monthly quota at all — up to 210,000 leads a week.
Can I use LeadMarina in the Claude mobile app?+
Yes. Connect it once on claude.ai or Claude Desktop and the connector is also available in the Claude mobile app.
