Overview

Description from the maker (original English)

Declare what your app does and where it operates; get cited, jurisdiction-specific findings.

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 lexlint https://mcp.lexlint.io/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": {
    "lexlint": {
      "url": "https://mcp.lexlint.io/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": {
    "lexlint": {
      "type": "http",
      "url": "https://mcp.lexlint.io/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.

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

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

Values you fill in

  • X-API-Key secret HTTP header
    Optional. A client that signs in with OAuth sends no key. A client that cannot sign in sends your own UnGovr Open Data key here, which LexLint checks against UnGovr's key store and meters per request…

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 6, 2026. The maker wrote them, not us; we show them as plain text.

  • set_profile

    Step 1 of the lint. Declare what the app does (activities) and where it will operate (jurisdiction slugs), from the app's own code: ask the user which app if they have not said, and lint only one whose code you can open (the open folder, a public repository, one the user connecte

  • run_lint

    Step 2 of the lint, and the one that returns findings. Pass the activities and jurisdictions set_profile validated, and get lint-style findings: which obligations apply, with severity (warn/info), citation, as_of_date, staleness, and confidence. warn: a live obligation binds the

  • get_law

    One jurisdiction's law from the LexLint law library, across all thirteen topics LexLint covers: AI law, scraping/crawling and access legality, personal-data and biometric privacy, product-security and cyber-resilience law, communications law (marketing messages, calls and texts,

  • resolve_domain_jurisdiction

    Best-effort mapping from a domain to the jurisdiction whose law governs its OPERATOR, for feeding into the other tools. Never uses server or edge-node location; IP addresses are refused. Costs one to four upstream requests, varying with how many domain-label candidates it tries b

  • check_access

    Preflight. Reports whether an UnGovr Open Data key reached LexLint, whether it is valid, how much of today's free allowance is left and when it resets, how current the law library is, and whether the LexLint plugin you are running is the latest published one. Call this first: a m

  • submit_feedback

    Send the developer's feedback on LexLint to the people who build it, recorded against their UnGovr account so we can write back. Run this ONLY on the developer's explicit yes. It may be raised unprompted in exactly one place, the close of a lint run whose upload approval was decl

  • upload_lint_run

    Store one lint run on the LexLint portal, against the UnGovr account that signed in or owns the key, and return the portal URL and, for a trial key, a share URL that opens the run with no sign-in for 30 days. This is the closing step of every run that produced findings, raised un

Common questions

Is LexLint: a lint for the law that governs software 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 (1.0.4) reached the registry 8 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?
