Exports leads from a search, campaign, or filtered set to Google Sheets, letting users send verified local-business data into a spreadsheet for review and sharing.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@LeadMarina MCP server Find roofing contractors in Austin, TX with a mobile number."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Verified local-business leads, inside your AI assistant. Search any niche in any US city, get each business's emails checked for deliverability and its phones checked for line type and carrier, then send the leads to Close, GoHighLevel, Google Sheets or a CSV, Excel or JSON file. You never leave the chat.
This is a remote MCP server. There is nothing to install or run:
https://leadmarina.com/api/mcpTransport: streamable HTTP (one POST per JSON-RPC message, plain JSON answers)
Auth: OAuth (sign in to LeadMarina in your browser), or a LeadMarina API key as a bearer token
REST API: https://leadmarina.com/docs, with an OpenAPI 3.1 document at https://leadmarina.com/openapi.json
This repository holds the listing: this README, client config examples, the
MCP registry's server.json and smithery.yaml. The server itself is
LeadMarina's hosted service.
Ask in plain language, for example:
"Find roofing contractors in Austin, TX with a mobile number."
"Which plumbers I've already collected have a safe email and over 50 reviews?"
"Send this search to Close."
"Every Monday, search HVAC contractors in Dallas and Fort Worth and email me a CSV."
"Estimate dentists across Colorado and Utah, then run it with a 2,000-lead cap."
Each lead is one local business: its listing (name, category, address, rating, reviews, website), up to 3 emails each marked safe, risky or invalid, up to 3 phones with line type and carrier, the owner's name where one can be found, and its social profiles.

You need a LeadMarina account. Every plan includes the MCP server, the free plan too: sign up.
OAuth (recommended). Add the server URL to your client. The first time a tool runs, your browser opens LeadMarina's sign-in and consent page. Nothing needs to be copied or pasted.
API key. Create a key on the API Keys page
and send it as Authorization: Bearer YOUR_API_KEY. The key spends your
leads, so keep it private and out of shared or committed config files.
Client set-up, with full files in examples/:
Client | How |
Claude (claude.ai or the desktop app) | Customize → Connectors → + → Add custom connector → paste the server URL. OAuth runs on first use, and the connector then works in the mobile app too. |

ChatGPT (developer mode) | Settings → Plugins → Developer mode → create an app with the server URL, authentication OAuth |
Cursor | One-click install, or |

Every tool carries MCP annotations: read-only tools say so, and
delete_automation is marked destructive. The tools that spend leads say so
in their descriptions, so your assistant can confirm with you first.
One lead is one delivered business, with all of its verification included. Lookups, reads and exports are free. See pricing and limits.
