Personal Email to Company Resolver MCP Server

Give it a free mail address (Gmail, Outlook, iCloud, Yahoo, and about 140 more consumer domains). Each run reads the public Gravatar profile for the address, the GitHub account whose public commits are signed with it, and, for a name with an employer, Mamba Labs Person LinkedIn URL Resolver. It returns one row per address with the person's name, likely employer, employer domain, and a confidence. It never contacts the mailbox and never opens LinkedIn.

What it does

• match_status is resolved (employer at 0.75 or more, billed), weak, name_only, corporate_email, not_found, invalid_email, or blocked, and only resolved is billed.

• employer_source says where the employer came from: gravatar, github, web_result, linkedin_headline, or email_domain. evidence_urls lists the public pages.

• The LinkedIn step raises the confidence when a LinkedIn result shows the employer as current and lowers it when it shows it as former.

All of the work runs on Apify. This package is a thin client that starts the actor run, waits for it, and hands back the dataset rows.

Quick start

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

Add this to your Claude Desktop config (claude_desktop_config.json), Cursor, or any MCP client:

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

Restart the client. The resolve_personal_email_employer tool appears.

Prerequisites

• Node.js 18 or newer.

• An Apify API token from console.apify.com/account/integrations, set as APIFY_TOKEN. The server lists its tool without a token; a call needs one.

Example prompts

• "These ten signups used Gmail addresses. Which companies do they work at?"

• "Find the employer behind this Outlook address and show me the evidence."

Tool

resolve_personal_email_employer. One tool. Example arguments:

{ "emails": ["sample.signup@gmail.com"] }

Inputs

Every buyer facing input of the actor, unchanged. Omitted inputs take the actor's own defaults.

Pricing

Pay per event on Apify, billed to your Apify account. Prices in USD.

Every other row is free. With use_linkedin_resolver on, Person LinkedIn URL Resolver bills its own events on top: $0.035 per person sent to it, found or not, plus $0.0005 per run on the free plan.

Your keys

The actor holds no key. github_token is optional and is your own, used for the run only. Mamba Labs pays the platform costs of the run, proxy traffic included.
