Summary

Prospect research answered where the email is being written.

Take the hosted path: a URL, one OAuth approval, and no key stored in the agent's config. The flow it supports is the short one — find the person, then get their details — done without leaving the draft.

What it is

An MCP server for DataLayer, a B2B data enrichment API covering companies and the people who work at them. A hosted remote server is the recommended path; the npm package is the stdio fallback for environments that cannot reach it.

What you get

A person looked up by who they are and where they work
A person enriched with verified contact details
A commercial database of companies and verified contacts behind both calls
A hosted endpoint at https://api.datalayer.sh/mcp over Streamable HTTP, with OAuth and Dynamic Client Registration
A stdio npm package, still maintained, for environments with no route to a remote server

Requirements

For the hosted server, paste the URL into your client and approve the OAuth prompt — no API key sits in the agent. Headless callers send an Authorization: Bearer header on POST /mcp instead.

Setup effort

Paste a URL, then sign in — add the endpoint to your client and sign in to the vendor
