Mobile Phone Waterfall MCP Server

Find a mobile phone number for each contact by calling your own phone data providers in order, Prospeo, Lusha, ContactOut, and FullEnrich, until one returns a number. One row per contact with the number in E.164 format, line type, country, a Do Not Call flag where the provider reports one, and the provider credits it spent.

It runs the Mobile Phone Waterfall actor (Actor ID 6OOgPktf7RIa5XCOP) on Apify.

The Prospeo path has been run live on a real key (2026-10-19). The Lusha, ContactOut, and FullEnrich steps are built to each provider's documented API but have not yet been run on a live key; every run summary lists them under providers_not_live_verified. No key is stored.

Setup

{
  "mcpServers": {
    "mamba-mobile-phone-waterfall-orchestrator": {
      "command": "npx",
      "args": ["-y", "@mambalabsdev/mcp-mobile-phone-waterfall-orchestrator"],
      "env": {
        "APIFY_TOKEN": "your-apify-token",
        "PROSPEO_API_KEY": "optional",
        "LUSHA_API_KEY": "optional",
        "CONTACTOUT_API_KEY": "optional",
        "FULLENRICH_API_KEY": "optional"
      }
    }
  }
}

APIFY_TOKEN is required to run the tool. The provider keys are optional and read from this server's environment, so they never pass through the model's context. With no provider key set, the run completes, calls nothing, and charges only the run start fee.

Inputs

contacts (each with any of full_name, first_name, last_name, company_domain, company_name, linkedin_url, email, id), or the single contact shortcuts full_name, company_domain, linkedin_url, email. Optional: provider_order, mobile_only, max_contacts, max_provider_credits, max_charge_usd.

A LinkedIn URL is passed to providers as an identifier. Neither this server nor the actor opens it.

How it runs

The server starts the actor run (POST /v2/acts/{id}/runs), polls it (GET /v2/actor-runs/{runId}) to a terminal status with a run timeout of 1,800 seconds, and returns the dataset. A run that does not succeed comes back as an error with its run ID.

Cost

Apify charges the actor's pay per event prices to your Apify account: a start event, a charge per contact on which at least one provider was called, and a charge per number found. Your providers charge their own credits on your keys. See the actor's pricing tab for current prices.
