PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • pdl_person_enrich

    Find the single best-matching person profile for a set of identifying attributes (name, email, phone, profile URL, company, etc.). Returns one record plus a likelihood score (1-10), or a 404 'no match' body. Use uniquely-identifying inputs for best results. API: GET /person/enric

  • pdl_person_identify

    Given broad, possibly-ambiguous attributes about a person, return up to 20 strongly-related profiles ranked by match score. Sits between enrich (1:1) and search (open-ended) — ideal when you can't uniquely resolve someone. API: GET /person/identify.

  • pdl_person_search

    Search the full PDL Person Dataset with an Elasticsearch query object OR a SQL string over the Person Schema (e.g. everyone with job_title_role='engineering' at a company). Returns matching profiles sorted by completeness; paginate with scroll_token. Each returned record costs 1

  • pdl_company_enrich

    Find the single best-matching company record. Requires a non-ambiguous input — name OR website OR ticker OR profile (website/ticker/profile resolve more reliably than name). Returns firmographics (industry, size, location, etc.) or a 404 'no match' body. API: GET /company/enrich.

  • pdl_company_search

    Search the full PDL Company Dataset with an Elasticsearch query object OR a SQL string over the Company Schema (e.g. all SaaS companies with 50-200 employees in the US). Paginate with scroll_token. Each returned record costs 1 credit. API: POST /company/search.

  • pdl_ip_enrich

    Enrich an IP address with its location, company, and (optionally) associated person data via a 1:1 match against PDL's IP dataset. API: GET /ip/enrich.

  • pdl_autocomplete

    Get suggested values for a search field along with the number of available records for each — useful for building valid Person/Company Search queries. Free on all plans. API: GET /autocomplete.

  • pdl_job_posting_search

    Search PDL's Job Posting Dataset (millions of active & historical postings sourced from company career pages) with an Elasticsearch query object OR a SQL string. Beta — may require plan access (HTTP 403 if not enabled). Each returned posting costs 1 credit. API: POST /job_posting

Common questions

Is People Data Labs MCP by usefulapi safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.35.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

People Data Labs MCP by usefulapi

Enrich and search people and companies, resolve identities, and enrich IPs — from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your People Data Labs API key.

Live endpoint: https://peopledatalabs.usefulapi.io/mcp · Homepage: https://usefulapi.io/peopledatalabs

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://peopledatalabs.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http peopledatalabs https://peopledatalabs.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "peopledatalabs": { "url": "https://peopledatalabs.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your People Data Labs credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/peopledatalabs/

On first connect you'll paste your People Data Labs API key. It's validated, stored per-user, and scoped to you.
