01 · Install NVEIL

before you install - you'll need

NVEIL_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add nveil-ai-nveil-toolkit -- uvx nveil

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "nveil-ai-nveil-toolkit": {
      "command": "uvx",
      "args": [
        "nveil"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

license AGPL-3.0 - declared in the repository

pypi package nveil - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.nveil-ai is GitHub-verified and matches the repo owner

06 · NVEIL FAQ

What is NVEIL?

Describe your data. Get production charts. Your data stays local. API Reference Examples Changelog

Is NVEIL still maintained?

Yes - as of 2026-09-18, its last commit was 2026-06-05. We re-verify nightly.

How do I install NVEIL?

Run `uvx nveil`. The README documents one environment variable (NVEIL_API_KEY) to set first. You can also paste the ready-made client config above.

Does NVEIL run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
