What the code does

We read the source, 2 d ago · rules ccca72095570

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

    src = os.path.join(PROJECT, src_name)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

Today is the operative word: we check Verified by NPC every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add npc-verify -- uvx npc-verify-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "npc-verify": {
      "args": [
        "npc-verify-mcp"
      ],
      "command": "uvx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.npc-verify]
command = "uvx"
args = ["npc-verify-mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "npc-verify": {
      "args": [
        "npc-verify-mcp"
      ],
      "command": "uvx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "npc-verify": {
      "args": [
        "npc-verify-mcp"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: NPC_VERIFY_API_URL (NPC Verification API base URL. Defaults to the local API.), NPC_VERIFY_API_KEY (API key for the NPC Verification API.). The author declared them in the registry entry; get the values from the project itself.

Verified by NPC — questions

Answers built from our own checks of this server.

Why is there no uptime for Verified by NPC?
Verified by NPC runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package npc-verify-mcp was installed 426 times last week.
How do I connect Verified by NPC?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls npc-verify-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use Verified by NPC?
The pypi package npc-verify-mcp was installed 426 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Verified by NPC open source?
We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
