Company Firmographic Enricher MCP Server

What it does

This server gives an AI client one tool:

• enrich_company_firmographics: enrich a company domain into employee band, industry, HQ, founded year, revenue estimate, logo, and description, parsed from the company's schema.org/Organization JSON-LD and HTML meta tags. Every record includes a source_signals array and a data_completeness score.

All of the work runs on Apify. This package is a thin client that routes the tool call to 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": {
    "company-firmographic-enricher": {
      "command": "npx",
      "args": ["-y", "@mambalabsdev/mcp-company-firmographic-enricher"],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

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

Prerequisites

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

Example prompts

• "Enrich stripe.com: employees, industry, HQ, founded year, and revenue estimate."
• "What firmographics can you find for gitlab.com, and how complete is the data?"
• "Pull company firmographics for these domains: stripe.com, gitlab.com, notion.so."
• "Find the employee band and HQ location for acme.com."

Tool and inputs

enrich_company_firmographics:

• domain (string): bare company domain to enrich, e.g. stripe.com. Provide this or domains.
• company_name (string): optional company name, used as a fallback label when the page does not expose one.
• domains (array): list of bare domains for batch processing. Takes precedence over domain.
• batchSize (number): domains enriched concurrently per wave in batch mode. Default 5, maximum 10.
• skipCache (boolean): force a fresh enrichment and ignore the 7 day result cache.
• failOnMostlyEmpty (boolean): by default the run ends FAILED when more than half the rows resolve no firmographic field, and this tool then returns an error. The rows are still saved, each with resolution_status and empty_reason. Set false to end the run SUCCEEDED and get the rows back. Default true.

The tool starts the actor run and polls it to a finished status, so a long run is not cut off at 300 seconds. The run is allowed 1,800 seconds. If it is still going two minutes after that, the call stops waiting and returns the run ID with a link to it in the Apify Console, where the results land when it finishes. A run that does not succeed comes back as an error with its run ID and status.
