PopNx MCP’s three pillars

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

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Law & government data
  • You need to fill in: X-Api-Key

Install

Pick the AI app you use, then copy the settings.

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http catalog https://dataandapis.com/mcp --header 'X-Api-Key: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "catalog": {
      "url": "https://dataandapis.com/mcp",
      "headers": {
        "X-Api-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "catalog": {
      "type": "http",
      "url": "https://dataandapis.com/mcp",
      "headers": {
        "X-Api-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • X-Api-Key secret HTTP header
    Your dataandapis.com API key (free account: 500 tokens a month). Optional for search_apis and get_api; required for call_api.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • search_apis

    Find APIs on dataandapis.com by the data they provide (e.g. 'sanctions screening', 'barcode nutrition', 'IP geolocation', 'company by domain', 'public holidays'). Returns up to 10 matches with slug, one-line summary, base URL and docs. Follow with get_api for the endpoints.

  • get_api

    Full reference for one API: every endpoint with method, path, path and query parameters with example values, request body and an example response, plus the token cost per call. Use the slug from search_apis.

  • call_api

    Make a live request to a dataandapis.com API with the user's API key (sent as X-Api-Key on this MCP connection). Give the API slug, the endpoint path from get_api (path parameters already filled in, e.g. '/v1/products/3017620422003'), optional query parameters and, for POST, a JS

Common questions

Is Data and APIs safe?

It passed 2 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?

You need to fill in: X-Api-Key

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 (1.0.0) reached the registry 10 days ago.

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: SOS.city public record, USVI Public Records, Korean Government Documents (HWPX)
