MCP support
Linkjar provides a remote MCP connector at `https://linkjar.com/mcp` for agents that cannot run its CLI.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Servers that need sign-in will prompt on first connect.
Tools
Details
From the project READMElinkjar
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 <[email protected]>"
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

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
