How RDAP + hiring signal) works

What Company Enrichment MCP (DNS/RDAP + hiring signal) does

Company Enrichment MCP (DNS/RDAP + hiring signal) turns a company domain into structured enrichment data for agent workflows. The free preview focuses on signals available from domain infrastructure and registration records: email provider, detected SaaS and technology products, domain age, and registrar.

The paid depth record extends the result beyond technical domain signals. It can return company name, industry, social links, contacts, legal registration identifiers such as a VAT number or company number, office address, and a live hiring signal. Legal identifiers are digit-validated, and the hiring signal is read across eight applicant-tracking systems.

How it works

An agent supplies a company domain for enrichment. The preview uses DNS-derived observations and RDAP registration data, allowing a keyless first-level lookup. The deeper request adds business and recruiting information, including a current hiring indicator based on ATS data.

Connecting does not require an API key. The paid request is handled through x402 and settles in USDC on Base. This creates a clear separation between the free domain preview and the paid, broader enrichment result.

Setup and configuration

The service is designed for MCP use and can be connected without an API key. Applications should provide a company domain when invoking enrichment. A workflow that only needs email infrastructure, detected technology, domain age, or registrar data can use the free preview.

Use the paid depth record when the workflow also needs firmographics, contacts, legal registration, office location, social profiles, or the hiring signal. Payment for that call requires USDC on Base through x402, so the calling environment must support that payment flow.

Tools and capabilities

  • Free keyless company preview from a domain.
  • Email-provider detection from DNS data.
  • SaaS and technology-stack detection from DNS signals.
  • Domain-age and registrar lookup through RDAP.
  • Paid firmographic, contact, social, legal, and office enrichment.
  • Live hiring signal checked across eight applicant-tracking systems.

The paid result includes legal registration data with digit validation for VAT or company numbers. The hiring output is intended as a live signal rather than a static company attribute, because it is read from applicant-tracking systems during enrichment.
