Permissions Found in Source Code

Found by scanning the linked source code. This listing connects to a hosted endpoint, so none of this runs on your machine: it describes what the server software does where it is hosted.

file_system

Applies to the server that hosts this plugin, not to your machine.

HTTP Network Access

Connects to external APIs or services over the internet.

env_vars

Applies to the server that hosts this plugin, not to your machine.

Shell Command Execution

How to Connect

Remote Plugin

No local installation needed. Your AI client connects to the remote endpoint directly.

Add this to your MCP configuration to connect:

Documentation

View on GitHub

From the project's GitHub README.

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 <sam@acme.com>"
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

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

<ref> 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:

Skill	What it does
`linkjar`	Every CLI command: send, personal links, settings, activity, rooms
`proposal`	Writes a client proposal page from a template and sends a link per decision-maker
`pitch-deck`	Builds a phone-friendly slide deck and sends a link per investor
`one-pager`	A sell sheet / leave-behind, optionally tailored to one account
`case-study`	Turns call notes and metrics into a case study (real quotes and numbers only)
`follow-up`	Reads activity and drafts who-to-contact-next emails

The writing skills ship a template.html with one <h2> 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.

Development

npm test     # node --test: arg parsing, zip writer, fake-server send/activity/refresh, OAuth flow
