Most outbound B2B pipelines fail because they rely on stale static databases instead of live company intent signals (like engineering or GTM job openings posted today on Greenhouse, Lever, or Ashby) and real-time DNS/MX verification.

To solve this without expensive headless browsers, I built the @apexsignal B2B Intelligence Suite — a 4-Actor HTTP/DNS microservice fleet on Apify with native Model Context Protocol (MCP) support (mcp.apify.com + stdio MCP server) and a ready-to-import n8n workflow.

🛠️ The 4-Step B2B Intelligence Architecture

  1. ATS Career & Job Listing API (apexsignal/ats-career-job-listing-api) Queries official public JSON endpoints for Greenhouse, Lever, Ashby, and Workable to detect companies actively hiring for specific roles or keywords in under 2 seconds.
  2. B2B Domain Contact, Email, Social & Tech Enricher (apexsignal/b2b-domain-contact-enricher) Extracts public business emails, phone numbers, LinkedIn/X/GitHub links, DNS MX/SPF/DMARC records, and 24+ technology stack fingerprints directly from company domains.
  3. B2B Company Executive & Founder Lead Finder (apexsignal/b2b-company-lead-finder) Discovers C-level executives, Founders, and VPs from JSON-LD Person schemas and team pages, paired with MX-verified corporate email addresses.
  4. Bulk Email MX & DNS Deliverability Verifier (apexsignal/bulk-email-mx-verifier) Verifies thousands of emails against live DNS MX hosts, SPF/DMARC security postures, role-account rules, and disposable domain lists before you send a single email.

🤖 Using with Claude Desktop, Cursor, or Windsurf via MCP

You can connect all 4 tools directly to Claude Desktop, Cursor, or VS Code in two ways:

Option A: Hosted Apify MCP Server (mcp.apify.com)

Add this to your claude_desktop_config.json or .cursor/mcp.json:

{ "mcpServers": { "apexsignal-b2b-suite": { "url": "https://mcp.apify.com/?actors=apexsignal/b2b-domain-contact-enricher,apexsignal/bulk-email-mx-verifier,apexsignal/ats-career-job-listing-api,apexsignal/b2b-company-lead-finder", "headers": { "Authorization": "Bearer <YOUR_APIFY_API_TOKEN>" } } } }

Option B: Open-Source Stdio MCP Server
