Domain to LinkedIn URL Resolver MCP Server

An MCP server that resolves a company domain or name to its LinkedIn company URL. It wraps the Mamba Labs Domain to LinkedIn URL Resolver actor on Apify and returns a Clay-ready flat JSON row to any MCP client.

What it does

Give it a company domain or a company name and it finds the matching LinkedIn company page, with a confidence score so you know how much to trust it. You also get firmographics such as employee count, industry, and headquarters, plus social links, all in one flat row ready for Clay, a CRM, or an AI agent workflow. All of the resolution runs on Apify. This package is a thin client that calls the actor and hands back the result.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config:

{
  "mcpServers": {
    "mamba-linkedin-resolver": {
      "command": "npx",
      "args": ["-y", "@mambalabsdev/mcp-domain-to-linkedin-url-resolver"],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

Get your token at https://console.apify.com/account/integrations, paste it in, and restart Claude Desktop. The resolve_linkedin_url tool will be available.

Prerequisites

• Node.js 18 or newer
• An Apify account with an API token

Example prompts

• "Find the LinkedIn page for stripe.com."
• "What is the LinkedIn company URL for openai.com? Include the confidence score."
• "Resolve the company named Figma to its LinkedIn URL and firmographics."
• "Get the LinkedIn URL, employee count, and industry for datadoghq.com."

Inputs

• company_domain (optional): the bare company domain, no https:// and no trailing slash. Example: stripe.com

Provide at least one of the two. If both are given, the domain takes priority.
