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.

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

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

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3

Run this in your terminal

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "linkjar": {
      "url": "https://linkjar.com/mcp"
    }
  }
}

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": {
    "linkjar": {
      "type": "http",
      "url": "https://linkjar.com/mcp"
    }
  }
}

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3
https://linkjar.com/mcp

Menu names can differ slightly by plan and over time.

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

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

What it can do

Compared with others in Otheri

  • More stars than 0% of the other 32461 servers in this category
  • Published to the registry more recently than 72% of the other 32461 servers in this category
  • Basic checks equal to or better than 100% of the other 32461 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Linkjar safe?

It passed 1 of 1 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 (1.0.1) reached the registry 15 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: Spec Driven Development, Remote Desktop Commander, dotnet-mcp

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

linkjar

Send decks, proposals, PDFs and HTML pages as branded, tracked links from your terminal or your AI agent, then see who opened them, how far they read and what they clicked.

npx linkjar login

npx linkjar send deck.pdf --for "Sam Lee " npx linkjar activity deck

Requires Node 18+. No dependencies. Install globally with npm i -g linkjar, or run it with npx linkjar.

Log in

linkjar login                 # opens your browser; the token is saved, never printed

linkjar login --no-browser # over SSH: open the printed link on any device linkjar login --key lj_... # or save an API key

In CI or agent sandboxes, set LINKJAR_API_KEY instead. Create keys at Settings → Claude, CLI & API on linkjar.com. The env var takes precedence over a saved login. The login is saved in ~/.config/linkjar/config.json (or under $XDG_CONFIG_HOME), readable only by you. linkjar logout removes it.

Commands

CommandWhat it does
send Publish a PDF, Office file, HTML file, folder with index.html, or HTML on stdin
update Replace what a link shows; the link stays the same
listRecent documents with view counts
activity Who opened it, when, how far they read (alias views)
responses What people submitted or signed on a fillable PDF (--csv for a spreadsheet, --save-signed for signed PDFs)
link --name --emailA personal link for one person
settings Password, email gate, allowed domains, expiry, call-to-action button
room Several documents behind one link
open Open the document's settings page
whoami, login, logoutAccount

is a link, its slug or its id. Every command has --help with examples. Add --json to any command for the raw API response. In normal output the first line is the link.

linkjar send ./proposal-site --title "Acme proposal" --password hunter22

linkjar send deck.pdf --email-gate --domains acme.com --expires 2026-12-31 linkjar send deck.pdf --cta-label "Book a call" --cta-url https://cal.com/me/intro cat page.html | linkjar send - --title "One-pager" linkjar settings acme-proposal --remove-password linkjar room "Acme deal room" acme-proposal case-study --email-gate

Use --url or LINKJAR_URL to point the CLI at another server, for example a local dev server.

For AI agents

skills/ holds agent skills for Claude Code, OpenClaw and similar agents:

SkillWhat it does
linkjarEvery CLI command: send, personal links, settings, activity, rooms
proposalWrites a client proposal page from a template and sends a link per decision-maker
pitch-deckBuilds a phone-friendly slide deck and sends a link per investor
one-pagerA sell sheet / leave-behind, optionally tailored to one account
case-studyTurns call notes and metrics into a case study (real quotes and numbers only)
follow-upReads activity and drafts who-to-contact-next emails

The writing skills ship a template.html with one per section, because the viewer reports which headings each person scrolled to. Ways to install them:

  • Claude Code plugin: this repo is also a Claude Code plugin and marketplace (.claude-plugin/):
  /plugin marketplace add rocketgems/linkjar

/plugin install linkjar@linkjar

- **Any agent:** copy the folders under `skills/` into the agent's skills folder, for

example ~/.claude/skills/.

For agents that can't run a CLI, such as Claude.ai or ChatGPT on the web, use the remote connector at https://linkjar.com/mcp instead.
